Gestational trophoblastic diseases, like the complete hydatidiform mole (CHM), are a group of human interrelated neoplasms whose ethiology and progression is poorly understood at the molecular level. We have previously reported the cloning and expression of a new tumor necrosis factor receptor (TNF-R) related transcript, named CHMS-I that encodes a potential death domain. Here we show that ectopic expression of the putative CHMS-1 death domain specifically induced apoptosis in a dose-dependent manner, in trophoblastic (JEG-3) and non-trophoblastic (COS-7) cells. We also investigated the expression of apoptosis-related molecules such as Bcl-2 and p53 and demonstrated that Bcl-2 is repressed in CHM while p53 is overexpressed in CHM compared with persistent gestational trophoblastic tumors. Altogether, these data indicate that the CHMS-I death domain is able to trigger apoptosis, thus suggesting that this new entity might be an important inducer of molar regression mechanisms in women.
