Kinase D demonstrates the NinaA amounts in cnx were indistinguishable from wt levels, suggesting the defects in Rh had been the consequence of the lack of Cnx, rather then a lack of NinaA. Calnexin Associates with Rh The association of Cnx with Rh was assessed by coimmunoaffinity experiments . Cnx was isolated in the stable complex with Rh , but didn’t bind to or elute from the immunoaffinity column inside the absence of Rh . These data indicated that Cnx and Rh physically associate within a protein complicated, steady by using a role for Cnx as being a molecular chaperone for Rh. Mutations in calnexin Result in Retinal Degeneration Examination within the cnx mutants uncovered they displayed an age related retinal degeneration . Photoreceptor cells in day previous cnx mutants displayed diminished rhabdomere dimension as when compared to wt .
In addition they displayed accumulations of rough ER membranes, dilated selleckchem description Golgi, and several sorts of deposits . These secretory pathway defects were consistent which has a failure in Rh maturation. The identity of the deposits is unknown, but they could possibly consist of degraded materials within the cells. At month, cnx mutants displayed a dramatic reduction of rhabdomeres in the R photoreceptor cells, when the R and R photoreceptor cell rhabdomeres remained . The Drosophila compound eye is manufactured up of about individual eye units identified as ommatidia. Each ommatidium incorporates eight photoreceptor cells . Only R photoreceptors express Rh, whereas R and R cells express a variety of various opsins . The finding that only R rhabdomeres degenerated, and not R and R, recommended the opsins located in R and R were expressed typically.
Calnexin Is Uniquely Expected by Rh in Photoreceptor Cells To verify regular expression from the small rhodopsins in R and hop over to this site R cells, we carried out immunocytochemical evaluation of Rh, Rh, and Rh opsins while in the cnx mutants. We identified all 3 opsins to get the right way localized to your rhabdomeres within the R and R cells , confirming that when Cnx was expected by Rh, it had been not needed through the R and R opsins. We examined irrespective of whether ER processing of other photoreceptor proteins was defective in the cnx mutant. Immunocytochemical examination unveiled that a further membrane protein, chaoptin, was present at its usual place within the rhabdomeres within the R photoreceptor cells in the two cnx mutants and wt .
In addition, we carried out immunoblotting examination to confirm that numerous primary phototransduction proteins, as well as the G protein subunit , the TRP and TRPL channels, PLC , arrestin , and arrestin had been all expressed at ranges indistinguishable from wt . These outcomes demonstrated that although Cnx was essential for processing of Rh, it was not necessary for expression of these other photoreceptor cell proteins.

The cofactor SAM can decompose spontaneously via three major pathways : hydrolysis of methyl sulfonium bond to SAH, cleavage of N ribosyl bond to adenine and intramolecular SN lactonization to methylthioadenosine . The SAM to SAH decomposition can interfere with all SAH mediated PMT activity assays . The Frankel laboratory uncovered that this degradation occurs at a slow fee and its impact could be mitigated by using Tris buffer in lieu of Hepes buffer and freshly purified SAM. SAM?s degradation also impacts the PMT action assays that count on MTAN as one particular coupling enzyme and adenine or its derivatives as readouts. Because MTAN is promiscuous toward SAH and MTA, all nonenzymatic SAM degrading goods will contribute signal readouts as enzymatic adenine manufacturing . Using the ATP mediated luminogenic assay being a model, our laboratory evaluated the result of three SAM degrading products and identified that SAH, MTA and adenine together gave fold higher background than SAH alone.
The spontaneous decomposition of SAM to SAH, MTA and adenine hence restricts the use of the SAH dependent chromogenic assays for PMTs of minimal activity. In lots of SAH primarily based chromogenic PARP Inhibitors assays, SAH is degraded in situ by coupling enzymes . The lack of accumulation of SAH is expected to become effective by releasing probable SAH inhibition of PMTs. Having said that, our laboratory showed that SAHbased chromogenic assays could very well be carried out in an uncoupled format by permitting SAH accumulation followed by SAH quantification. The prospective SAH inhibition won?t be dominant should the examined PMTs have lower affinity to SAH or maybe a higher concentration of SAM is employed. On top of that, reactive thiol based mostly chromogenic PMT action assays should certainly be carried out underneath conditions 100 % free of lowering reagents this kind of as DTT and mercaptoethanol, for the reason that these reagents interfere with all the assays by reacting together with the dyes straight .
Cysteines of PMTs and coupling enzymes are one more supply of high background in reactive thiol primarily based PMT action assays. This impact is usually minimized through the use of cysteinefree Parietin coupling enzymes. HTS adaptability of PMT action assays PMT activity assays have caught escalating interest for his or her prospective medium large throughput screening of PMT inhibitors . As an early effort towards HTS of PRMT inhibitors, the Bedford laboratory formulated an antibodybased ELISA PMT exercise assay and utilized it to recognize a suite of PRMT inhibitors from a , compound library; the Imhof laboratory utilized a radiometric filter binding assay to a pooled mixture of , compounds and recognized an SU inhibitor chaetocin; Purandare et.
al. created a comparable radiometric filter binding assay and recognized a pyrazole based mostly CARM inhibitor. The medium throughput format of these assays, however feasible for any little library of compounds, is just not efficient to manage recent HTS compound libraries, which frequently consist of K entities. Kubicek et. al. designed the first HTS assay for PMTs . On this dissociation enhanced lanthanide fluoroimmunoassay , N terminal biotinylated H amino acid peptide was dimethylated by Ga at HK and then immobilized onto a neuroavidin coated well microtiter plane.

An example for this method was reported in an earlier review by Quivy et al. for latent infection in the cell line, the place the authors reported synergistic results of HDAC inhibitors and also the phorbol ester phorbol myristate acetate , which would target the protein kinase C NF B pathway . Right here, we describe a drug screening assay constructed to recognize HIV reactivating drug combinations and report on the class of chosen FDA authorized anticancer medicines that prime latent HIV infection for reactivation or right trigger HIV reactivation being a consequence of their cell differentiating capacity . Importantly, in T cell populations that might not react with total reactivation to large activator concentrations, pretreatment with differentiating medicines permitted for full reactivation in the population degree. Complete program wide reactivation are going to be a prerequisite for viral eradication. We go over how our findings relate to past reviews that the cell differentiating polar compound N N hexamethylene bisacetamide as well as the second generation cell differentiating drug suberoylanilide hydroxamic acid the two set off HIV reactivation .
In summary, our information suggest that selleck chemical Wnt-C59 differentiating medication or compounds, like a class of therapeutic agents, could end up a part of a long term induction treatment to eradicate the reservoir of latently HIV infected T cells. Supplies AND Tactics Cell culture, plasmids, and reagents. All T cell lines and key T cells were maintained in RPMI supplemented with mM L glutamine, U ml penicillin, g ml streptomycin, and heat inactivated fetal bovine serum . Principal T cell cultures were even more supplemented with U ml IL . The latently infected JGFP cells, CA T cells, and EF T cells along with the viruses used to create these cell lines are described earlier . All cell lines had been created applying green fluorescent protein reporter viruses that express all viral gene products.
FBS was obtained from HyClone rtk inhibitors and was examined on the panel of latently infected cells to ensure that the utilized FBS batch did not spontaneously set off HIV reactivation . The phorbol ester phorbol myristate acetate , N N hexamethylene bisacetamide , cytarabine, azacytidine, rebeccamycin, aphidicolin, and oxaliplatin have been purchased from Sigma, whereas recombinant human tumor necrosis factor alpha was obtained from R D. SAHA was purchased from Cayman Chemical compounds. Daunorubicin, doxorubicin, amanitin, ICRF , and camptothecin had been purchased from Calbiochem Dichloro beta D ribofuranosylbenzimidazole was purchased from Alexis Biochemicals. A retroviral murine stem cell virus DsRedExpress plasmid was implemented for generation within the red fluorescent protein barcoded JGFP cell populations.
In vitro generation of latently HIV infected major T cells. Peripheral blood mononuclear cells from buffy coats of wholesome donors obtained with the American Red Cross or one other business vendor wereCDT cell depleted implementing anti CD DynaBeads.

Most significant, discontinuities in GFP myosin II fluorescence inside arcs get closer together with time, steady with arc contraction, and BB treatment effects in flaccid arcs that move inward in the slow and haphazard manner due solely to your continued pushing force of actin retrograde flow during the LP. Kinetic coupling in between TCR MC movement and cortical actin network movement at the IS We observed an extremely robust correspondence among the charges of centripetal actin movement and inward TCR MC movement across each the LP dSMAC and LM pSMAC regions on the IS. Also, this solid kinetic coupling among cortical actin flow and inward TCR MC movement was maintained right after every single drug treatment method. This robust coupling is in contrast to a previous report making use of bilayer engaged Jurkat T cells , by which the price of inward TCR MC movement with the periphery within the IS was reported to be ? the charge of centripetal actin movement.
As described in alot more detail within the Introduction, this as well as other research particularly those who have characterized the results of bodily barriers inside the bilayer around the rates of TCR MC motion have led to a dissipative or frictional coupling model of TCR MC actin cytoskeleton interaction that allows slippage in between the MC and actin movement. Though TCID clinical trial we definitely think that this kind of slippage would come about if we had utilised bodily barriers, we feel that inside the absence of this kind of barriers the coupling among TCR MCs and actin movement is most likely very tight. That said, at the very least part of the main difference in between our examine and that of Kaizuka and colleagues as regards the kinetic coupling among actin movement and TCR MC motion may be thanks to feasible variations in bilayer problems amongst the 2 studies .
It is also potential that, from the research by Kaizuka et al the quantitation of actin movement fee was restricted largely to your LP dSMAC , whereas the quantitation of TCR MC movements was produced predominately inside the LM pSMAC, major towards the discrepancy among their respective centripetal rates. Certainly, considerably stays to become learned relating to the elements and physical properties hydralazine from the mechanisms that couple TCR MCs and integrin clusters to cortical actin movement in the course of IS formation. Our demonstration that TCR MCs exhibit two distinct costs of centripetal motion throughout the IS can truly be reconciled that has a substantial quantity of charges reported previously.
To begin with, the rapidly price across the LP dSMAC reported here corresponds somewhat very well with rates on the periphery of the IS reported by quite a few groups . Moreover, the slow price throughout the LM pSMAC reported here corresponds really nicely with charges reported for areas of the Is are basically certainly within the LP dSMAC, that’s, for the LM pSMAC .

In addition, the inhibitory efficacy of FLLL in liver cancer cells was examined. Liver cancer or hepatocellular carcinoma is a single from the most major of cancers. According on the American Cancer Society, the five year relative survival rates are currently at for all phases for regional metastasis, and . for distant metastasis. Hence, there is an urgent should create additional helpful treatment options for liver cancer. Sufferers with any stage of liver cancer may appropriately be considered candidates for clinical trials working with new inhibitors as a result of the bad response to chemotherapy as conventionally utilized. The constitutive activation of STAT is commonly detected in clinical incidences of liver cancer and in greater than of human liver cancer cell lines but not in usual or non transformed human cells .
The constitutive activation of STAT in liver cancer is often on account of the aberrant methylation selleck killer deal and silencing of Suppressor of Cytokine signaling and . Constitutive STAT signaling contributes to liver cancer progression by selling angiogenesis, survival, metastasis, and development of liver cancer cells . Yet again, our data demonstrated that FLLL could efficiently inhibit STAT phosphorylation and induced apoptosis in four independent human liver cancer cell lines. These outcomes indicate that FLLL also has possible as a therapeutic agent for liver cancer cells expressing persistently activated STAT. On top of that, FLLL also potent to inhibit STAT phosphorylation and induce apoptosis in MDA MB breast cancer cells. The potency of FLLL was further confirmed in MDA MB breast cancer xenografts in mouse model in vivo.
Hence, FLLL isn’t only potent in cancer cells in vitro but in addition in tumor cells in animal model in vivo and might have future possible to target tumor cells that express persistently activated STAT in cancer patients. Curcumin is description demonstrated as a dietary agent which can inhibit STAT . FLLL was made as being a new analog which specifically targets STAT with larger binding potency and selectivity. Our data demonstrated that FLLL was much more potent than curcumin to inhibit STAT phosphorylation and STAT DNA binding action, downregulate STAT target genes, and induce cancer cells apoptosis. Having said that, the phosphorylation of mTOR and ERK was not certainly decreased by FLLL. FLLL also has little result on STAT phosphorylation stimulated with IFN g.
Furthermore, FLLL exhibited minor inhibition on some of the tyrosine kinases containing SH or both SH and SH domains, and various protein kinases by using kinase profile assay. These results further assistance the specificity of FLLL to inhibit STAT. Right after activated by some cell surface cytokines, such as IL , IFN g, JAK phosphorylates and activates cytoplasmic STAT protein to an active dimer, which translocates for the nucleus and induce the transcription of distinct target genes .

Smurf binding from the nucleus to SMAD induces export and recruitment towards the activated T Rs, wherever it causes degradation of receptors and SMAD through proteasomal and lysosomal pathways . Smurf also interacts with SMAD and induces SMAD ubiquitylation and translocation into the cytoplasm . For appropriate translocation towards the nucleus, the SMADs incorporate a nuclear localization like sequence that’s acknowledged by importins . Interestingly, the nuclear translocation of SMADs was also described in vitro to take place independently of additional importin like components, for the reason that SMAD proteins can right interact with nucleoporins, such as CAN Nup . Complicated of SMAD and SMAD is retained while in the nucleus by interactions with more protein binding partners and DNA. Dephosphorylation and dissociation of SMAD transcriptional complexes are considered to end this retention, allowing export of RSMADs from the nucleus . Numerous protein binding partners give a different venue for regulatory inputs controlling the exercise of SMADs.
Each SMAD spouse mixture VEGF kinase inhibitor targets a specific subset of genes and recruits either transcriptional co activators or co repressors. Members of a lot of DNAbinding protein families participate as SMADs cofactors, such as FOX, HOX, RUNX, EF, AP, CREB ATF, Zincfinger as well as other families. The SMAD cofactors vary in different cell kinds, therefore figuring out the cell sort dependent responses . By association with DNAbinding cofactors, SMADs reach target gene specificity and target specificity. Stimulation of diverse cells by TGF leads to quick activation or repression of the handful of hundred genes; probably, the pool of activated SMAD proteins is shared amid unique companion cofactors . On chromatin degree, SMADs can recruit histone acetyltransferases.
A few research exposed that TGF proteins influence transcription of different genes via interaction of your MH domain of SMADs with sequence specified transcription factors and co activators CBP and p. CBP and p interact with SMAD, SMAD, SMAD and SMAD in vitro and in vivo, Tanshinone IIA plus the interaction between the SMADs and CBP p is stimulated in response to TGF . Additionally, histone deacetylases and chromatin remodeling complexes are also associated with SMAD regulation. On this way, SMADs functionally interact using a assortment of transcription elements and regulate varied signaling pathways at the same time . SMADs act as sequence specific transcription components; then again, they can regulate cell fate by alternate mechanisms. Recent information indicate that R SMADs associate with all the p Drosha DGCR miRNA processing complicated to manage miRNA processing in a liganddependent and RNA sequence unique manner.
Thus far, more than TGF BMP regulated miRNAs are described . Non SMAD signaling Diversity of TGF signaling in cells is established not just by a variety of ligands, receptors, SMAD mediators or SMAD interacting partners, but also through the skill of TGF to activate other signaling pathways .

Regardless of enhancements in imaging technologies in excess of the past two decades, nearly all lung cancers are found because of the advancement of distant metastases. Hematogenous spread with numerous organ involvement is regularly reported. Generally, metastases from lung cancer involve the liver, adrenal glands, bone and brain . Muscle metastases are uncommon . Mandible metastasis from lung cancer is usually a unusual issue that may occur in the late stages from the sickness . We describe two situations of non minor cell lung cancer metastasis to thigh muscle and mandible bone , and talk about treatments and outcomes. Situation presentation Case A year old Caucasian female presented to our facility using a history of suitable shoulder discomfort that had persisted for a number of months and was resistant to medical treatment options. She reported no systemic illness. She had been a smoker for years.
A contrast enhanced computed tomography scan in the chest uncovered a correct upper lobe lung mass and mediastinal lymphadenopathy that did not involve the chest wall. CT guided biopsy within the lung mass offered a histopathological diagnosis of adenocarcinoma was good, staining for p was adverse PF-03814735 . On even further staging, brain metastasis was detected . A whole entire body F fluorodeoxyglucose positron emission tomography scan was performed and it unveiled greater FDG uptake inside the primary correct upper lobe lung mass, mediastinum and brain of . and respectively . She underwent neurosurgery and the histological report described the brain lesion as compatible with origin in the main lung tumor. She acquired six cycles of systemic chemotherapy consisting of cisplatin and pemetrexed.
At a single month comply with up, a PET CT scan showed sinhibitor FDG uptake in entire body areas of curiosity. She received Gy sequential palliative radiation treatment to the lung mass, and Gy on full brain, respectively. Inhibitors shows an axial part on the treatment method preparing CT scan fused with all the PET scan. 3 months just after RT, a CT scan uncovered sinhibitor lung and selleck chemicals recommended you read brain illness. She was enrolled in an experimental protocol with erlotinib hydrochloride plus ARQ placebo . 1 month later, she came to our Radiation Therapy Division for adhere to up, and she referred to ha skin lesion first noticed on her perfect thigh two weeks previously. A physical examination showed phlebitis and edema of the reduce limb. Because of this we prescribed minimal molecular excess weight heparin.
In spite of multimodality therapy, a whole new CT complete body scan pointed out progressive metastatic illness that has a rare lesion in the soft tissue while in the medial compartment of your correct thigh, infiltrating the skin . Ultrasonography was performed to evaluate the thigh lesion; it showed an inhomogeneous, hypoechoic picture, with irregular margins .

Entity form errors are denoted by T, boundary only mistakes are denoted by B and precision is denoted by P. The LTS MetaMap system led to a significant increase within the all round precision of healthcare entity recognition. Truly, LingPipe outperformed MetaMap in sentence segmentation on our check corpus. LingPipe uncovered appropriate sentences in which MetaMap discovered sentences containing boundary mistakes and some sentences have been even cut inside the middle of medical entities . A qualitative research of the noun phrases extracted by MetaMap and Treetagger chunker also shows the latter creates much less boundary errors. To the extraction of remedy relations, we obtained . recall precision and . F measure. Other approaches very similar to our operate like obtained recall precision and . F measure for that extraction of treatment relations. Semrep obtained recall, precision and . F measure on the set of predications such as the treatment connection .
Then again, provided the differences in corpora and within the nature of relations, these comparisons should Palomid 529 PI3K inhibitor be thought to be with caution. Annotation and exploration platform: MeTAE We implemented our approach inside the MeTAE platform which lets to annotate medical texts or files and writes the annotations of medical entities and relations in RDF format in external supports . MeTAE also will allow to investigate semantically the out there annotations by a type based mostly interface. User queries are reformulated making use of the SPARQL language according to a domain ontology which defines the semantic types related to healthcare entities and semantic relationships with their doable domains and ranges. Solutions consist in sentences whose annotations conform on the consumer query together with their corresponding documents .
A number of semantic relation extraction approaches only handle dyphylline relation detection . While in the context of health-related query answering techniques, we’re not simply interested in relation detection but additionally from the linked healthcare entities. We focus on seeking source,relation,target triples such the source plus the target have recognized categories and this kind of that the relation is legitimate w.r.t domain know-how and w.r.t linguistic concerns . On this context, exactly the same sentence may perhaps include several triples supply,relation,target . A initial evaluation of your false positives shows the primary error triggers are: mistakes in the extraction of medical entities patterns of your treatment relation that also cover forms of expression of other relations and sentences that have feasible supply and target entities while not them remaining linked with the remedy relation.
Applying external segmentation equipment brought improvements when compared with the direct utilization of MetaMap. Then again, other segmentation equipment exist and could display a numerous conduct. We carried out a comparative research of a more substantial set of equipment inside a latest job .

Nevertheless, there are actually various lines of proof suggesting involvement in the ER in autophagosome formation. The isolation membrane continues to be proposed to get differentiated from the ER, and indeed, the establishing isolation membrane is often linked with and directly linked to the rough ER Research in yeast have proven that early secretory pathway proteins are expected for yeast autophagosome formation. In addition, the ER targeted, but not mitochondrial targeted, Bcl suppresses autophagy by sequestering Beclin Last but not least, DFCP translocates from the ER to LC linked omegasome. In the present study, we showed that the early autophagic structures associate with all the ER, supporting the thought that the ER plays a critical function in autophagosome formation. Having said that, it stays unknown whether or not these ULK Atg structures represent some extraordinary blog in the ER membrane itself or some unknown distinct construction that tightly associates using the ER.
This blog seems to get composed of no less than two several elements, for the reason that localization of DFCP and erk inhibitor other Atg proteins are distinct, whilst they’re usually in shut proximity to one another . Our even further examination uncovered that VMP transiently associates with the pretty early autophagic structures . Nonetheless, the functional phase of VMP seems not to be upstream of Atg proteins, considering that VMP silencing triggers accumulation of abnormal autophagic membranes containing ULK, WIPI , DFCP and AtgL . Although it was reported that VMP interacts with Beclin , the phenotype of VMP siRNA was several from that of PI kinase suppression by wortmannin. On top of that, almost all of Beclin was not co fractionated with VMP .
These benefits suggest that main perform of VMP in the autophagy pathway is just not through regulation of PI kinase action. VMP might possibly provide very important part that happen to be required for a later stage of autophagosome formation. Further evaluation is going to be necessary to elucidate the position of VMP in autophagosome formation. Products and Systems Cell culture and transfection. MEFs , HeLa and PI3K alpha inhibitor HepG cells had been cultured in Dulbecco?s modified Eagle?s medium supplemented with FBS, g ml penicillin and streptomycin inside a CO incubator . NIHT cells had been maintained in DMEM containing bovine calf serum and the antibiotics . Atg KO, FIP KO, and Atg KO MEFs have been generated previously. For starvation, cells had been washed with PBS and incubated in amino acid totally free DMEM without having serum . FuGENE reagent was made use of for transfection.
Wortmannin and puromycin have been bought from Sigma . Plasmids. Image Consortium cDNA clones encoding mouse DFCP and human VMP , an ORFeome collaboration clone encoding human ERGIC, and a TOYOBO cDNA clone encoding human SecA were obtained from Invitrogen , Promega or TOYOBO , respectively.

Wortmannin treatment just about absolutely abolished the late phosphorylation of MARCKS induced by PAR AP without affecting the initial response. In contrast, PAR AP induced MARCKS phosphorylation was much more resistant on the action of wortmannin. As a way to find out whether or not the reduction of sustained PKC activation accounts for that capability of wortmannin to reverse platelet aggregation, the phorbol ester TPA was utilised to directly activate PKC. As proven in Inhibitor C, submit addition of TPA to PAR stimulated platelets wholly attenuated the inhibitory result of wortmannin. In contrast, TPA only partially prevented the inhibition of thrombin induced platelet aggregation induced by wortmannin plus YD . To even further verify the importance of sustained PKC activation in irreversible platelet aggregation, we additional the general PKC inhibitor GF X straight away right after stimulation of platelets with thrombin or APs.
Inhibitor D displays that posttreatment with GF X didn’t drastically influence thrombin induced platelet aggregation; however, when it had been combined with YD , the aggregation was diminished and grew to become reversible. In contrast, publish treatment with GF X PD0332991 alone was capable to reverse platelet aggregation in response to PAR AP or PAR AP . We following attempted to find out which signalling molecule is responsible for PIK dependent PKC activation and platelet aggregation. The purpose of Akt, a serious downstream effector of PIK, was investigated by utilizing selective inhibitors at concentrations reported to inhibit Akt in human platelets . As shown in Inhibitor A, the two SH and AKT inhibitor V considerably decreased the Ser phosphorylation of GSKb induced by thrombin, PAR AP and PAR AP, which can be largely dependent on Akt in platelets , hence confirming the effectiveness of those two inhibitors.
Within this issue, however, neither SH nor AKT inhibitor V markedly prevented MARCKS phosphorylation induced by these stimulators . Also, SH and AKT inhibitor V only somewhat lowered the maximal extent or the original price of platelet aggregation in response to thrombin, PAR Dexamethasone AP or PAR AP, and didn’t impact the stability of platelet aggregation . Even inside the presence of YD , SH or AKT inhibitor V also failed to reverse thrombin induced platelet aggregation . Combined blockade of ADP PY receptor and PAR reverses thrombin induced platelet aggregation It’s been reported that PAR mediated PIK activation is largely dependent to the ADP PY Gi pathway ; we so investigated regardless of whether a PY antagonist can also be capable of disrupt the stability of thrombin induced platelet aggregation when in blend by using a PAR antagonist.
As shown in Inhibitor A, the PY antagonist Me SAMP abolished Akt phosphorylation, at each Thr and Ser, induced by thrombin or PAR AP, and selectively inhibited the late phosphorylation of MARCKS .
