Osmotic stress induces apoptosis in extravillous trophoblast cells. Role of TRPV-1
2019
Abstract In different tissues hyperosmolarity induces cell differentiation. Nevertheless an exacerbated hyperosmolar stress alters the normal cellular development. The transient receptor potential vanilloid 1 (TRPV-1) is a non-selective cation channel that is activated by hyperosmolarity and participates in many cellular processes. TPRV-1 is expressed in human placenta at term. Here, we evaluated the expression of TRPV-1 in first trimester extravillous trophoblast cells and its participation in the survival of these cells exposed to hyperosmolar stress. Our results showed that hyperosmolar stress up-regulates the expression of TRPV-1 and induces the apoptosis in Swan 71 cells. In addition, the inhibition of TRPV-1 abrogates the apoptotic events.
