MicroRNA-23a inhibits endometrial cancer cell development by targeting SIX1.

The present study focused on exploring the inhibitory mechanism of microRNA (miR)-23a in endometrial cancer. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) was used to investigate miR-23a expression in endometrial tissues and endometrial cancer cells. A colony formation assay using crystal violet staining was performed to compare cell proliferation, while wound-healing and Transwell assays were performed to compare cell migration and invasion.

The Increased PTK7 Expression Is a Malignant Factor in Cervical Cancer.

Cervical cancer is one of the most common malignant neoplasms in gynecology. Protein tyrosine kinase 7 (PTK7) with an inactive kinase domain is an important regulator of multiple Wnt pathways under normal and various pathological conditions and overexpressed in various tumors; however, the clinical and biological significance of PTK7 in cervical cancer is still unknown. In the present study, the protein expression level of PTK7 was detected in clinical cervical cancer patient samples, and the relationship between PTK7 expression and clinicopathological features was analyzed.

Effect of nutritional supplement combined with exercise intervention on sarcopenia in the elderly: A meta-analysis.

Objectives: This systematic review was conducted to explore whether nutritional supplement can improve the benefits of exercise intervention on sarcopenia in the elderly.

Methods: Databases, including PubMed, Embase, Cochrane Library, Web of Science, CINAHL, CBM, CNKI, WANFANG, and VIP, were searched. All related papers with randomized controlled trials (RCT) methodology that were included in the databases from inception to 19 July 2016 were selected for the study.
