Recently, a unique family of membrane progestin receptors (mPRalpha, mPRbeta, and mPRgamma) was identified, which may be responsible for mediating rapid, nongenomic actions of progestins in a variety of target tissues. In this study, the mPRalpha and mPRbeta isoforms from zebrafish were shown to be rapidly and specifically activated by the maturation-inducing steroid (MIS) of this species, 4-pr...
Due to the environmental and anthropogenic impacts that continue to threaten the reproductive success of polar bears, a more detailed understanding of their reproductive cycle is needed. Captive populations of polar bears provide an excellent opportunity to learn more about the reproductive physiology of the species. Progestin (P4) and androgen (T) metabolites in urine, and their ratio (P4:T), ...
BackgroundThere is few scientific evidence of good quality on the relationship between an ischemic stroke and isolated use progestins. In general, it does not suggest elevation this risk. The World Health Organization (WHO) classifies continuation etonogestrel implant as category 3 if event occurred while using it.CaseFemale patient, 16 years old, initiated with headache, hemiparesis, lip rhyme...
Progestins are widely used as oral contraceptives and hormone replacement therapy. Recently it has been demonstrated that many progestins are inhibitors of P-glycoprotein, possibly explaining gender differences in drug actions. In vitro evidence suggested that at least norgestimate might also inhibit other transporters like the multidrug resistance-associated protein 2 (MRP2). We therefore inve...
