In Drosophila, heterozygosity in the pro-apoptotic gene hid significantly reduces apoptosis that is induced by ionizing radiation (IR). Therefore, mechanisms that regulate Hid levels can potentially contribute to life-or-death decision of an irradiated cell. 3'UTR of hid mRNA contains 5 potential binding sites for bantam microRNA. Ectopic expression of ban(More)
Tumor suppressor p53 plays a key role in DNA damage responses in metazoa, yet more than half of human tumors show p53 deficiencies. Therefore, understanding how therapeutic genotoxins such as ionizing radiation (IR) can elicit DNA damage responses in a p53-independent manner is of clinical importance. Drosophila has been a good model to study the effects of(More)
We report a phenomenon wherein induction of cell death by a variety of means in wing imaginal discs of Drosophila larvae resulted in the activation of an anti-apoptotic microRNA, bantam. Cells in the vicinity of dying cells also become harder to kill by ionizing radiation (IR)-induced apoptosis. Both ban activation and increased protection from IR required(More)
