The aim of the present study was to determine the effect of cyclin‑dependent kinase 7 (CDK7) silencing on the sensitivity of the HEC‑1‑A endometrial carcinoma cell line to cisplatin [cis‑dichlorodiammineplatinum (II), or DDP]. Four CDK7 siRNA fragments were designed and synthesized based on the gene sequence of CDK7 and transfected into HEC‑1‑A cells. The RNA interference of the fragments was c...

Exocyclic adducts of DNA bases, such as etheno- and hydroxyalkano- ones, are generated by a variety of bifunctional agents, including endogenously formed products of lipid peroxidation. In this work we selectively modified cytosines in the 5'-d(TTT TTT CTT TTT CTT TTT CTT TTT T)-3' oligonucleotide using: chloroacetaldehyde to obtain 3,N(4)-alpha-hydroxyethano- (HEC) and 3,N(4)-etheno- (epsilonC...

BACKGROUND Safe, effective and convenient antiemetic regimens that preserve benefit over repeated cycles are needed for optimal supportive care during cancer treatment. NEPA, an oral fixed-dose combination of netupitant, a highly selective NK1 receptor antagonist (RA), and palonosetron (PALO), a distinct 5-HT3 RA, was shown to be superior to PALO in preventing chemotherapy-induced nausea and vo...

A geographic information system ~GIS! based approach is presented for the development of a terrain model based on stream channel representation of the U. S. Army Corps of Engineers Hydrologic Engineering Center’s River Analysis System ~HEC-RAS! hydraulic model. As input, the approach requires a completed HEC-RAS simulation, a digital elevation model ~DEM!, and a GIS representation of the stream...

BACKGROUND The aim of this study was to investigate the sensitivity to rapamycin of endometrial cancer cells with different phosphatase and tensin homologue (PTEN) expression to understand the mechanism of resistance to mammalian target of rapamycin (mTOR) inhibitors in the treatment of endometrial cancer. MATERIAL AND METHODS Twenty specific pathogen-free female BALB/c mice received transpla...

Endometrial cancer is the most common female reproductive cancer in the United States and is associated with deregulated tight junction protein expression. Given the highly estrogen-responsive nature of this tissue, we investigated the effects of estrogen and its agonist, 4-OH TAM, on the expression and subcellular localization of the tight junction protein claudin-4 (CLDN-4), in HEC-1A endomet...

The smectites represent a versatile class of clay minerals with broad usage in industrial applications, e.g., cosmetics, drug delivery, bioimaging, etc. Synthetic hectorite Na0.7(Mg5.5Li0.3)[Si8O20](OH)4 is a distinct material from this class due to its low-cost production method that allows to design its structure to match better the applications. In the current work, we have synthesized for t...

Introduction:  With repeated courses of chemotherapy, chemotherapy-induced nausea and vomiting (CINV) becomes progressively more difficult to control. The aim of this study was to evaluate whether the antiemetic efficacy of the triple combination aprepitant, palonosetron and dexamethasone could be sustained for up to six cycles of highly emetogenic chemotherapy (HEC) (cisplatin ≥ 50 mg/m(2) ). ...

PURPOSE EphA2 overexpression is frequently observed in endometrial cancers and is predictive of poor clinical outcome. Here, we use an antibody drug conjugate (MEDI-547) composed of a fully human monoclonal antibody against both human and murine EphA2 (1C1) and the tubulin polymerization inhibitor monomethylauristatin F. EXPERIMENTAL DESIGN EphA2 expression was examined in endometrial cancer ...
