Here, we investigate the mechanism and function of LKB1, a Ser/Thr kinase mutated in Peutz-Jegher syndrome (PJS). We demonstrate that LKB1 physically associates with p53 and regulates specific p53-dependent apoptosis pathways. LKB1 protein is present in both the cytoplasm and nucleus of living cells and translocates to mitochondria during apoptosis. In(More)
OBJECTIVES Preclinical data suggest an important role for the sarcoma proto-oncogene tyrosine kinase (SRC) in the oncogenesis of epithelial ovarian cancer (EOC) or primary peritoneal carcinoma (PPC). The Gynecologic Oncology Group (GOG) conducted a Phase II trial to evaluate the efficacy and safety of dasatinib, an oral SRC-family inhibitor in EOC/PPC, and(More)
OBJECTIVE This two-stage phase II study was designed to assess the activity of the combination of temsirolimus and bevacizumab in patients with recurrent or persistent endometrial carcinoma (EMC). METHODS Eligible patients had persistent or recurrent EMC after receiving 1-2 prior cytotoxic regimens, measurable disease, and Gynecologic Oncology Group(More)
The use of histone deacetylase (HDAC) inhibitors has shown promise for a variety of malignancies. In this investigation, we define the activity of this class of inhibitors in combination with traditional cytotoxic chemotherapy in endometrial cancer cells. Significant reductions in growth were observed in Ark2 and KLE endometrial cancer cells following(More)
The granulin-epithelin precursor (GEP/PCDGF), a 68-88 kDa secreted glycoprotein, has been shown to be an important growth and survival factor for ovarian cancer cells. Furthermore, GEP expression is a predictor of patient survival in metastatic ovarian cancer cells. Up to this point, however, the molecular mechanisms and clinical relevance of a GEP-mediated(More)
Aberrant DNA methylation is an important molecular alteration commonly detected in various malignancies. Hypermethylation and expression silencing have been frequently found in multiple genes including those for steroid receptors, tumor suppressors, and DNA repair factors. Differential DNA methylation patterns are detected in type I and type II endometrial(More)
OBJECTIVE To evaluate whether the addition of topotecan can improve the efficacy of carboplatin and paclitaxel in first-line treatment of advanced epithelial ovarian cancer. METHODS Meta-analysis was performed using a random effects model. RESULTS Four randomized controlled trials with a total of 3632 patients were identified and included in the(More)
Objective: The myocardial bridging (MB) prevalence, anatomic characteristics of MB, and the relationship between characteristics of MB in mural coronary artery segment and coronary atherosclerosis were analyzed. Methods: In this perspective nonrandomized controlled study, a total of 1 132 patients who admitted to our hospital for suspected or known coronary(More)
