The purpose of the present study was to elucidate expressions of ERβ1 and ERβ2 expression in papillary thyroid cancer (PTC). ER β splicing variants expressions were examined on formalin-fixed, paraffin-embedded thyroid tissues from 106 PTCs and 30 nodular thyroid goiters (NTGs) by immunehistochemical methods using Elivision plus two-step system. There was significant difference in the subcellular localization of ERβ1 expression (P<0.001), but not...

One of the hallmarks of parturition in most mammals is a dramatic drop in plasma levels of progesterone (P4), which promotes myometrial relaxation, prior to labor. In humans and some other primates however, the opposite occurs and placental P4 production increases with advancing pregnancy. The expression of nuclear progesterone receptor (PR)-responsive genes is decreased in the primate uterus at term, which suggests ‘functional’ progestin withdrawal involves repressi...
