Abstract

Postterm pregnancy represents a condition associated with trophoblast apoptosis. Kisspeptin is a peptide able to induce apoptosis by a specific receptor, GPR54, through the upregulation of proapoptotic genes. The aims of the study were to evaluate (1) the messenger RNA (mRNA) expression of kisspeptin, GPR54, Bax/Bcl2, and p21 in postterm placentas and (2) kisspeptin ability to act on apoptosis in the third trimester placental explants. Placental specimens were collected from spontaneous term and postterm delivery and kisspeptin, GPR54, Bax/Bcl2, and p21 mRNA expression levels were analyzed by real-time polymerase chain reaction. Placental explants, collected from elective term cesarean sections, treated with different doses of kisspeptin were analyzed by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL). The expression levels of all the genes studied in postterm placentas were significantly higher than in-term placentas. Kisspeptin-induced apoptosis in placental explants with a dose-dependent effect, and TUNEL assay demonstrated the kisspeptin involvement in the apoptotic placental processes. Our present findings led us to hypothesize that kisspeptin may represent a placental proapoptotic agent acting in phys...Continue Reading

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
