Visfatin is a cytokine secreted by visceral adipose tissue, which plays an important role in obesity, diabetes, insulin resistance, atherosclerosis and polycystic ovarian syndrome. Additionally, visfatin is also involved in the metabolic syndrome-associated malignancies such as breast, colon, gastric and endometrial cancers. Visfatin inhibitor might be a potential antitumor therapeutic strategy for inhibiting the growth of many cancers.

Robotic-assisted laparoscopic surgery is the most common approach for the treatment of early-stage endometrial and cervical cancers in the US. Surgical staging requires pelvic and often aortic lymphadenectomy, depending on the primary tumor characteristics. Pelvic and aortic lymphadenectomy procedures may also be indicated for debulking of larger metastases to improve disease control. The infra-renal basin is an important anatomic site of metastasis from pelvic tumors, and robotic dissection techniques for this site have been described...

OBJECTIVE: Gynecologic Oncology Group (GOG) 177 demonstrated that addition of paclitaxel to a backbone of adriamycin/cisplatin improves overall survival (OS) and progression-free survival (PFS) for patients with advanced or recurrent endometrial cancer. Using patient specimens from GOG-177, our objective was to identify potential mechanisms underlying the improved clinical response to taxanes. Stathmin (STMN1) is a recognized poor prognostic marker in endometrial cancer that functions as a microtubule depolymerizing protein, allowing cells to transit rapidly through mitosis...

Endometrial cancer (EC) is the estrogen-dependent gynecologic malignancy, however the molecular mechanism involved in the development and progression of EC remain unclear. The aim of this study was to investigate the role of RIZ1 in EC. Immunohistochemical analysis revealed that RIZ1was decreased in EC than in normal endometrium. Lower RIZ1 level was correlated with high-grade carcinoma (p = 0.048) and positive expression of ERα (p = 0.004). In EC cells, estrogen could down regulated the expression of RIZ1, however, ICI182,780 could up regulated the expression of RIZ1...

The TGF-β/Smad and the PI3K/AKT signaling pathways are important regulators of proliferation and apoptosis, and their alterations lead to cancer development. TGF-β acts as a tumor suppressor in premalignant cells, but it is a tumor promoter for cancerous cells. Such dichotomous actions are dictated by different cellular contexts. Here, we have unveiled a PTEN-Smad3 regulatory loop that provides a new insight in the complex cross talk between TGF-β/Smad and PI3K/AKT signaling pathways. We demonstrate that TGF-β triggers apoptosis of wild-type polarized endometrial epithelial cells by a Smad3-dependent activation of PTEN transcription, which results in the inhibition of PI3K/AKT signaling pathway...

Carcinogenesis is a multistep multifactorial process that involves the accumulation of genetic and epigenetic alterations. In the past two decades, there has been an exponential growth of knowledge establishing the importance of epigenetic changes in cancer. Our work focused on reviewing the main role of epigenetics in the pathogenesis of endometrial carcinoma, highlighting the reported results concerning each epigenetic mechanistic layer. In a previous review, we assessed DNA methylation alterations. The present review examines the contribution of histone modifications, chromatin remodeling and noncoding RNA alterations for endometrial carcinogenesis...

We present a case of an endometrial cancer patient with germline mutation in MutS homolog 6 (MSH6), associated with Lynch syndrome. A 60-year-old Korean woman had a personal history of colon cancer 23 years ago. She also had a family history of endometrial cancer and colon cancer of her sisters and brothers. Immunohistochemistry was negative for MutL homolog 1 (MLH1) and positive for MutS homolog 2 (MSH2). Based on these findings, she underwent genetic counseling and testing that revealed a frameshift germline mutation at MSH6 (c...

Endometrial cancer is the most common gynaecological malignancy encountered in developed countries and the second most common in the developing world. The five-year survival rate of patients with endometrial cancer diagnosed at a late stage is <30%. Therefore, it is critical to develop a suitable chemotherapeutic regimen for late-stage endometrial cancer. Cisplatin (CDDP) is a first-line chemotherapeutic drug for endometrial cancer chemotherapy. The present study investigated the molecular mechanism underlying the effect of CDDP on endometrial cancer from the perspective of cell autophagy...

The stratification of cancer into subtypes that are significantly associated with clinical outcomes is beneficial for targeted prognosis and treatment. In this study, we integrated somatic mutation and gene expression data to identify clusters of patients. In contrast to previous studies, we constructed cancer-type-specific significant co-expression networks (SCNs) rather than using a fixed gene network across all cancers, such as the network-based stratification (NBS) method, which ignores cancer heterogeneity...
