Pro-inflammatory signals induce 20α-HSD expression in myometrial cells: A key mechanism for local progesterone withdrawal.

J Cell Mol Med 2021 Jun 10. Epub 2021 Jun 10.

Lunenfeld Tanenbaum Research Institute, Mount Sinai Hospital, Toronto, ON, Canada.

Metabolism of progesterone (P4) by the enzyme 20α hydroxysteroid dehydrogenase (20α-HSD) in myometrial cells is postulated to be a mechanism for P4 withdrawal, which occurs concomitant to uterine inflammation (physiologic or infection-induced) and associated activation of transcription factors: NF-кB and AP-1, common to term and preterm labour. We found that 20α-HSD protein is significantly increased in human myometrium during term labour, and in mouse uterus during term and preterm labour. Treatment of human myometrial cells with the pro-inflammatory mediators, lipopolysaccharide (LPS, mimicking infection) and 12-O-tetradecanoylphorbol-13-acetate (TPA, mimicking inflammation), induced 20α-HSD gene expression and increased 20α-HSD protein abundance.

Importance of the origin of mesenchymal (stem) stromal cells in cancer biology: "alliance" or "war" in intercellular signals.

Cell Biosci 2021 Jun 10;11(1):109. Epub 2021 Jun 10.

Unit Research, Fundación Hospital de Jove, Avda. Eduardo Castro 161, 33290, Gijón, Asturias, Spain.

Mesenchymal stem cells (MSCs) play a central role in the intercellular signaling within the tumor microenvironment (TME), exchanging signals with cancer cells and tumor stromal cells, such as cancer-associated fibroblasts and inflammatory mononuclear cells. Research attributes both pro-tumor and anti-tumor actions to MSCs; however, evidence indicates that MSCs specific effect on the tumor depends on the source of the MSCs and the type of tumor. There are consistent data proving that MSCs from reproductive tissues, such as the uterus, umbilical cord or placenta, have potent anti-tumor effects and tropism towards tumor tissues. Read More
