Individual and joint associations of per- and polyfluoroalkyl substances (PFAS) with gallstone disease in adults: A cross-sectional study.

Disturbances in the enterohepatic circulation are important biological mechanisms for causing gallstones and also have important effects on the metabolism of Per- and polyfluoroalkyl substances (PFAS). Moreover, PFAS is associated with sex hormone disorder which is another important cause of gallstones. However, it remains unclear whether PFAS is associated with gallstones.

Biomaterializing the advances in uterine tissue engineering.

The uterus is considered to be a unique wound-healing model and distinguished by the repeated shedding of the endometrium and self-traceless regeneration. Common curettage, cesarean section, and other operations often cause endometrial and myometrial defects and obstetric and gynecological complications, leading to a high demand for uterine repair or partial replacement. However, the structure and function of the uterus are complicated.

Upregulation of microRNA-31 targeting integrin α5 suppresses tumor cell invasion and metastasis by indirectly regulating PI3K/AKT pathway in human gastric cancer SGC7901 cells.

To verify the hypothesis that upregulation of microRNA-31 (miR-31) targeting integrin α5 (ITGA5) suppresses tumor cell invasion and metastasis by indirectly regulating phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway in human SGC7901 gastric cancer (GC) cells. The miRTarBase was used to predict whether ITGA5 is the target gene of miR-31, which was further confirmed by luciferase reporter gene assay. The SGC7901 GC cells were divided into five groups including the blank, miR-31 mimic, miR-31 mimic control, miR-31 inhibitor, and miR-31 inhibitor control groups.

MicroRNA‑145 inhibits the malignant phenotypes of gastric carcinoma cells via downregulation of fascin 1 expression.

MicroRNA (miR)‑145 has been demonstrated to act as a tumor suppressor, and deregulation of fascin 1 (FSCN1) has been observed in several types of human malignancy, including gastric carcinoma. However, the molecular mechanism underlying the function of miR‑145, specifically its targets in gastric carcinoma have yet to be fully elucidated. In the present study, downregulation of miR‑145 and upregulation of FSCN1 was identified in gastric carcinoma cell lines, compared with normal gastric mucosal epithelial cells.
