se anti Actin was used as control anti body. Membranes were washed four times with kinase inhibitor Gemcitabine TTBS and then incubated for 1 hour with anti rabbit or anti mouse HRP conjugated secondary antibody followed by chemiluminescence ECL detection and ex posure to autoradiography film. Films were scanned with HP scanjet8200 and the images were collected and analysed using ImageJ soft ware. Statistically significant differences between patients were estimated with the Student t test. For mRNA, gene ontology analysis has been carried out using DAVID and GSEA. Illumina ID of differential expressed genes was uploaded to the Inhibitors,Modulators,Libraries DAVID database and the analysis was performed using the algorithm within the softwares.

With GSEA, the whole genome with expression value were uploaded to the software and compared with catalog C5 gene ontol ogy gene sets in MsigDB, which contains 233 GO cellular component gene sets, 825 GO biological process gene sets, 396 GO molecular function gene sets. Inhibitors,Modulators,Libraries For miRNA, TargetScan was used to find the glo bal target of DE miRNAs, which were dysregulated by at least two fold and the target gene list was uploaded to DAVID as well. mRNA and miRNA correlation ana lysis has been performed using SA BNs. Genomes are under constant threat of damage from exogenous factors and endogenous processes that result in DNA lesions. Correspondingly, cells have evolved elaborate DNA damage response mechanisms to maintain genome integrity Inhibitors,Modulators,Libraries and stability. DDR integrates the DNA repair process with Inhibitors,Modulators,Libraries the cell cycle regulation, chroma tin dynamics and programmed cell death, requiring delicate coordination of hundreds of genes.

Because DNA Drug_discovery damage underlies the onset of cancer, aging, immune deficiencies, and other degenerative diseases, urgent needs of public health have made DDR a major target of study for decades. DDR is highly conserved during evolution. Essential components of the DDR network, including ATM ATR pathway, non homologous ends joining and ho mologous recombination repair, share homologues among almost all the eukaryotes. Therefore, studies of the DDR in lower eukaryotes can provide valuable infor mation to elucidate the mechanism in higher organisms. Because of their experimental amenabilities, budding yeast and fission yeast have become excellent models for DDR research. Fission yeast separated from budding yeast about 1,000 million years ago during evolution.

S. pombe contains about 150 metazoan homologous genes which cant be found in S. cerevisiae, and a similar number is seen when this comparison is made for S. cerevisiae. sellectchem This emphasizes the advantage of using both yeasts for basic studies. With the completion of the Saccharomyces Genome Deletion Project in 1999, genome wide screens using a deletion library have become an effective way to identify novel genes involved in DDR. Using such systematic screens, scientists have discovered 40 genes required for repairing DNA lesions caused by MMS, 31 genes involved in DDR to UV, and 107 new loci that influence sensi
