Cellular 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...
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 ...
متن کاملtranscriptional responses to cinnamaldehyde in mycobacterium tuberculosis
results results of the current study showed that the minimum inhibitory concentration value of cinnamaldehyde against m. tuberculosis was 200 µg/ml. moreover, rt-pcr data showed that a total of 25 genes were regulated by the cinnamaldehyde. of these, 12 genes were up-regulated, and 13 genes were down-regulated. conclusions cinnamaldehyde is a pattern to expand the new anti-tb drugs, because the...
متن کاملToxicity from radiation therapy associated with abnormal transcriptional responses to DNA damage.
Toxicity from radiation therapy is a grave problem for cancer patients. We hypothesized that some cases of toxicity are associated with abnormal transcriptional responses to radiation. We used microarrays to measure responses to ionizing and UV radiation in lymphoblastoid cells derived from 14 patients with acute radiation toxicity. The analysis used heterogeneity-associated transformation of t...
