Methylation status of TUSC3 is a prognostic factor in ovarian cancer.

Background: Current prognostic information in ovarian cancer is based on tumor stage, tumor grade, and postoperative tumor size. Reliable molecular prognostic markers are scarce. In this article, the authors describe epigenetic events in a frequently deleted region on chromosome 8p22 that influence the expression of tumor suppressor candidate 3 (TUSC3), a putative tumor suppressor gene in ovarian cancer.

hVps37A Status affects prognosis and cetuximab sensitivity in ovarian cancer.

Purpose: Although prognostic and predictive factors in ovarian cancer have been extensively studied for decades, only few have been identified and introduced to clinical practice. Here, we evaluate hVps37A (HCRP1) as a possible novel predictive marker for ovarian cancer. hVps37A was originally described as a member of the membrane-trafficking ESCRT-I complex mediating the internalization and degradation of ubiquitinated membrane receptors.

The role of c-FLIP(L) in ovarian cancer: chaperoning tumor cells from immunosurveillance and increasing their invasive potential.

Objective: In the current study, we aimed to investigate the role of the long isoform of cellular Fas-associated death domain-like interleukin-1beta-converting enzyme (FLICE)-like inhibitory protein (c-FLIP(L)) in ovarian cancer (OC) development by using RNA interference (RNAi) in vitro and in vivo.

Methods: TRAIL-resistant human OC cell lines were genetically manipulated by RNAi-mediated suppression of c-FLIP(L). Subsequently, the genetic alteration that was introduced into the various OC cell lines was characterized in vitro and in vivo.

BAMBI is overexpressed in ovarian cancer and co-translocates with Smads into the nucleus upon TGF-beta treatment.

Objective: Transforming growth factor beta (TGF-beta) signaling via Smads plays a central role in carcinogenesis. Bmp and activin membrane-bound inhibitor (BAMBI) was initially described as a pseudoreceptor antagonizing TGF-beta receptor activation, thus impairing signaling. Here we wanted to estimate the role of BAMBI in ovarian cancer.
