NKX3.1 activates cellular response to DNA damage.
The prostate-specific tumor suppressor homeodomain protein NKX3.1 is inactivated by a variety of mechanisms in the earliest phases of prostate carcinogenesis and in premalignant regions of the prostate gland. The mechanisms by which NKX3.1 exercises tumor suppression have not been well elucidated. Here, we show that NKX3.1 affects DNA damage response and cell survival after DNA damage. NKX3.1 e...

متن کاملCellular metabolic response to DNA damage
DNA damage elicits a cellular signaling response that initiates cell cycle arrest and DNA repair. The metabolic response to DNA damage is largely unknown. Here we report a novel metabolic response to genotoxic stress. DNA damage triggers a critical block in the uptake of glutamine, a mitochondrial substrate essential for cellular proliferation. Sirtuins regulate both cellular metabolism and str...
متن کاملCellular responses to DNA damage.
For many years, the study of the regulation of the SOS network was complicated by both the complexities of the responses and the interrelationships of the key regulatory elements. However, recently the application of powerful genetic and molecular biological techniques has allowed us to gain a detailed picture of the regulation of this complex network. The network is now known to consist of mor...
متن کاملCellular responses to DNA damage.
Cells are constantly under threat from the cytotoxic and mutagenic effects of DNA damaging agents. These agents can either be exogenous or formed within cells. Environmental DNA-damaging agents include UV light and ionizing radiation, as well as a variety of chemicals encountered in foodstuffs, or as air- and water-borne agents. Endogenous damaging agents include methylating species and the rea...
