Researchers from University of Tokyo report on findings in apoptosis
May 26th, 2009
"Abnormal regulation of placental apoptosis and proliferation has been implicated in placental disorders. Recently, several DNA-damaging agents were reported to induce excessive apoptosis and reduce cell proliferation in the placenta; however, the molecular pathways of these toxic effects on the placenta are unclear," researchers in Tokyo, Japan report. "The aim of the present study was to determine the involvement of TRP53, a tumor suppressor that mediates cellular responses to DNA damage, in the induction of apoptosis and cell cycle arrest in the developing placenta. For this purpose, we treated pregnant mice on Day 12 of gestation with 10 mg/kg of etoposide and 5-Gy...
