Role of DNA Methylation in Cell Cycle Arrest Induced by Cr (VI) in Two Cell Lines
Hexavalent chromium [Cr(IV)], a well-known industrial waste product and an environmental pollutant, is recognized as a human carcinogen. But its mechanisms of carcinogenicity remain unclear, and recent studies suggest that DNA methylation may play an important role in the carcinogenesis of Cr(IV). The aim of our study was to investigate the effects of Cr(IV) on cell cycle progress, global DNA m...
متن کاملCell cycle arrest is not yet senescence, which is not just cell cycle arrest: terminology for TOR-driven aging
Cell cycle arrest is not yet senescence. When the cell cycle is arrested, an inappropriate growth-promotion converts an arrest into senescence (geroconversion). By inhibiting the growth-promoting mTOR pathway, rapamycin decelerates geroconversion of the arrested cells. And as a striking example, while causing arrest, p53 may decelerate or suppress geroconversion (in some conditions). Here I dis...
متن کاملChenopodium Botrys as a Source of Sesquiterpenes to Induce Apoptosis and G1 Cell Cycle Arrest in Cervical Cancer Cells
Conducting cell apoptosis pathways is a novel strategy in cancer treatment. This study aimed to explain that C. botrys essential oil could induce apoptosis and arrest the cell cycle in HeLa cells. Cytotoxic and apoptogenic effects of the essential oil of Jerusalem-oak (Chenopodium botrys L.), which was obtained from the aerial parts of the plant, were evaluated in HeLa cells. Cell viability was...
متن کاملInterferon (IFNγ) induces cell cycle arrest in RCC cell lines
We have recently demonstrated that the anti-proliferative effect of interferon (IFNg) in RCC is due to an increased production of nitric oxide (NO) which in turn inhibits the induction of arginase (ARG2). The growth of cultured murine RCC cell lines was inhibited in 85% in IFNg treated when compared to un-treated cells. In contrast only 33% of these cells were inhibited by IFNg. These results i...
متن کاملCell cycle arrest is not senescence
DNA damaging agents and radiation, cytotoxins and anti-cancer drugs, telomere erosion and cytokines, culture shock and mitogenic stimuli, oncogenes and tumor suppressors can induce both cell cycle arrest and cellular senescence. Due to this semi-coincidence, senescence is confused with cell cycle arrest, or even more misleadingly, with growth inhibition. With such misconceptions, cellular senes...
