Linc-ROR Regulates and by Competitively Binding miR-145-5p to Affect the Proliferation and Migration of Gastric Cancer Cells.

Gastric cancer is the third leading cause of cancer-related deaths worldwide, and research on gastric cancer pathogenesis is fundamental. Long intergenic non-coding RNAs (lincRNAs) control cancer initiation and progression through several mechanisms, with the competitive endogenous RNA (ceRNA) regulatory network being the most common. In this study, hybridization revealed that long intergenic non-protein coding RNA-regulator of reprogramming (linc-ROR) was highly expressed in gastric cancer cells and was mainly cytoplasmic-positive.

The estrogen/miR-338-3p/ADAM17 axis enhances the viability of breast cancer cells via suppressing NK cell's function.

Natural killer (NK) cells are the critical elements of the innate immune response and implicated in rapidly recognizing and eliminating cancer cells. However, the tumor-suppressive ability of NK cells is often impaired in several cancer types. The critical roles of microRNAs have been elucidated by increasing evidences, while the regulation of miR-338-3p in anti-tumor activation of NK cells and its relationship with estrogen in breast cancer (BC) are still confusing.

Microstructure and Phase Evolution of Ti-Al-C-Nb Composites Prepared by In Situ Selective Laser Forming.

In the present work, a novel Ti-Al-C-Nb composite was prepared using in situ selective laser forming (ISLF). The formation mechanism of the Ti-Al-C-Nb bulks, which were synthesized using elemental titanium, aluminum, and carbon (graphite) powders via ISLF techniques, was investigated. The results showed that the TiAl and TiC phases were the dominant synthesis products during the chemical reactions, and these occurred during the ISLF process.

Clinical Experience of Intracorporeal Hand-sewn Anastomosis Following Totally Laparoscopic Pylorus-Preserving Gastrectomy for Middle-Third Early Gastric Cancer.

Introduction: Pylorus-preserving gastrectomy (PPG) has been accepted as a representative function-preserving procedure for early gastric cancer (EGC) in the middle stomach. Totally, intracorporeal laparoscopic gastrectomy can provide better aesthetics, be less invasive, and allow faster postoperative recovery. Here, we first describe the surgical procedure of totally laparoscopic pylorus-preserving gastrectomy with intracorporeal hand-sewn anastomosis (TLPPG-IHSA).

circTADA2A Retards the Progression of Colorectal Cancer via Regulating miR-1229/BCL2L10 Signal Axis.

Mounting evidence has proven that circRNAs act as pivotal modulators in the initiation and development of CRC. Although the function of circTADA2A has been explored in osteosarcoma and breast cancer, the specific role of circTADA2A in CRC remains unknown.
