MicroRNA‑155‑5p inhibits trophoblast cell proliferation and invasion by disrupting centrosomal function.

Recurrent miscarriage is used to refer to more than three pregnancy failures before 20 weeks of gestation. Defective trophoblast cell growth and invasion are frequently observed in recurrent miscarriage. Several microRNAs (miRs), including miR‑155‑5p, are aberrantly upregulated in recurrent miscarriage; however, the underlying molecular mechanisms remain unclear.

Rice straw-derived chitosan-enhanced plasticizers as biologically and environmentally friendly alternatives for sustainable materials.

Plasticizers like Bis(2-ethylhexyl)phthalate (DEHP) are commonly used to enhance plastic properties but pose environmental and health risks. This study successfully derived plasticizers X and Y from rice straws, demonstrating efficacy in chitosan polymer coatings. Chitosan-based polymers exhibit exceptional hardness, with a value of 300 MPa, due to their enriched structure and robust chitosan bonding.

Upregulation of miR-20b-5p inhibits trophoblast invasion by blocking autophagy in recurrent miscarriage.

Recurrent miscarriage is defined as more than three pregnancy failures occurring before 20 weeks of gestation. Poor differentiation of the endometrial stroma or defective trophoblast cell invasion at the maternal-fetal interface leads to recurrent miscarriages. Several miRNAs, including miR-20b-5p, are aberrantly regulated in recurrent miscarriages; however, the underlying molecular mechanisms remain unclear.

Polo‑like kinase 1 selective inhibitor BI2536 (dihydropteridinone) disrupts centrosome homeostasis via ATM‑ERK cascade in adrenocortical carcinoma.

Adrenocortical carcinoma (ACC) is a rare but malignant tumor. Surgical removal, radiotherapy and combined chemotherapy are commonly used to treat ACC. Despite efforts for several decades, the mortality rate of ACC remains high after treatments.

PDGF-AA activates AKT and ERK signaling for testicular interstitial Leydig cell growth via primary cilia.

Testes control the development of male reproductive system. The testicular interstitial Leydig cells (Leydig cells) synthesize testosterone for promoting spermatogenesis and secondary sexual characteristics. Type A platelet-derived growth factor (PDGF-AA) is one of the most important growth factors in regulating Leydig cell growth and function.
