Backgrounds: SIRT1 plays an important role in many physiological processes, including metabolism, neuronal protection, senecence and inflammatory, by staging histones and multiple transcription factors. However, the complex mechanisms of SIRT1 signaling in tumors are not yet fully understood, as it acts as both an oncogen and a tumor suppressor. On the other hand, it has been shown that the Lnc...
dna methylation plays an important role in carcinogenesis through epigenetic silencing of tumor suppressor genes. aberrant methylation usually results from changes in the activity of dna methyltransferases (dnmts). some studies show that the overexpression of the dnmts may lead to aberrant methylation of tumor suppressor genes. also the overexpression of dnmts may be related to methylation stat...
Introduction: Gastric cancer is a multifactorial disease and the fourth most common cancer in the world and the second cause of death from cancer. This study was designed and performed to investigate CDH1 and RUNX3 genes expression in healthy and tumor marginal tissue of people with gastric cancer. Methods: In this case-control study, 64 samples including 32 samples of gastric tumor tissue a...
Accumulation of gene changes and chromosomal instability in response to cellular DNA damage lead to cancer. DNA damage induces cell cycle checkpoints pathways. Checkpoints regulate DNA replication and cell cycle progression, chromatin restructuring, and apoptosis. Checkpoint kinase 2 (chk2) is activated in response to DNA lesions. ATM phosphorylate chk2. The activated Chk2 kinase can phosphoryl...
