2003 MAR 13 - (NewsRx.com & NewsRx.net) -- Survivin is an apoptosis antagonist.
According to recent research from Japan, "survivin, a protein that inhibits apoptosis, is expressed in a variety of tumor cells."
"We detected survivin-specific mRNA and protein in normal placental tissues, two human choriocarcinoma cell lines (JEG-3 and BeWo), and a trophoblastic cell line (tPA30-1) by reverse transcription-polymerase chain reaction (RT-PCR), Northern blotting, and Western blotting," described A. Shiozaki and colleagues, Toyama Med & Pharmaceutical University, Department Obstetrics & Gynecology.
"Immunohistochemically, survivin was localized to normal villous cytotrophoblasts, normal extravillous trophoblasts, cytotrophoblasts in hydatidiform mole, and choriocarcinoma cells."
"Antisense oligonucleotides for survivin dose-dependently induced apoptosis in two choriocarcinoma cell lines (JEG-3 and BeWo) and a trophoblastic ...
