Cellular 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 کاملNKX3.1 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 کاملTriplex-Induced DNA Damage Response
Cellular DNA damage response is critical to preserving genomic integrity following exposure to genotoxic stress. A complex series of networks and signaling pathways become activated after DNA damage and trigger the appropriate cellular response, including cell cycle arrest, DNA repair, and apoptosis. The response elicited is dependent upon the type and extent of damage sustained, with the ultim...
متن کاملChemotherapy induced DNA damage response
Chemotherapeutics target rapidly dividing cancer cells by directly or indirectly inducing DNA damage. Upon recognizing DNA damage, cells initiate a variety of signaling pathways collectively referred to as the DNA damage response (DDR). Interestingly, the pathways used to elicit this response are as varied as the types of DNA damage induced. However, the activation of these various pathways has...
متن کاملCellular Responses to Cisplatin-Induced DNA Damage
Cisplatin is one of the most effective anticancer agents widely used in the treatment of solid tumors. It is generally considered as a cytotoxic drug which kills cancer cells by damaging DNA and inhibiting DNA synthesis. How cells respond to cisplatin-induced DNA damage plays a critical role in deciding cisplatin sensitivity. Cisplatin-induced DNA damage activates various signaling pathways to ...
