Placental extracellular vesicles from women with severe preeclampsia alter calcium homeostasis in cardiomyocytes: an ex vivo study.

Women with severe preeclampsia (sPE) exhibit a heightened risk of postpartum cardiovascular disease compared with those with normotensive pregnancies (NTP). Although placental extracellular vesicles (EVs) play a crucial role in feto-maternal communication, their impact on cardiomyocytes, particularly in the context of sPE, remains unclear. This study investigated the effect of sPE-associated placental EVs (sPE-Plex EVs) on cardiomyocyte calcium dynamics.

A microRNA is the effector gene of a classic evolutionary hotspot locus.

In Lepidoptera (butterflies and moths), the genomic region around the gene is a "hotspot" locus, repeatedly implicated in generating intraspecific melanic wing color polymorphisms across 100 million years of evolution. However, the identity of the effector gene regulating melanic wing color within this locus remains unknown. We show that none of the four candidate protein-coding genes within this locus, including , serve as major effectors.
