Abstract
Pathologic hyperplasia of various pancreatic endocrine cells is rare but has been long known. β cell hyperplasia contributes to persistent hyperinsulinemic hypoglycemia of infancy, which is commonly caused by mutations in the islet ATP-sensitive potassium channel, and to non-insulinoma pancreatogeno...

Abstract
Our analysis revealed the regulation of inflammatory processes via thymic hormones that could be prospective for therapeutic application. This regulation may be mediated through thymic hormone effects on peripheral immune cell activities and bidirectional coupling between thymic hormones and the hyp...

Abstract
Opioids are widely used for the management of acute and chronic pain. They are also abused for recreational purposes. Long term use may lead to abnormalities in the endocrine system. The axis mainly affected is the gonadal axis leading to hypogonadism. However adrenal insufficiency and growth hormon...

Abstract
Neoadjuvant endocrine therapy improves surgical outcomes for postmenopausal women with bulky hormone receptor-positive breast cancer. Recent studies indicate that this approach may also be used in the management of smaller tumors with the hope of predicting outcomes from adjuvant endocrine manipulat...

Abstract
We have compared fracture repair between Cyp24a1-/- mice and wild-type controls. We have observed a delay in the mineralization of the cartilaginous matrix of the soft callus in Cyp24a1-/- mutant animals, accompanied by reduced expression of chondrocyte marker genes. These results show that Cyp24a1...

Abstract
Since its discovery in the 1920s, relaxin has enjoyed a reputation as a peptide hormone of pregnancy. However, relaxin and other relaxin family peptides are now associated with numerous non-reproductive physiologies and disease states. The new millennium bought with it the sequence of the human geno...

Abstract
The kisspeptin/kisspeptin receptor (KISS1R) system is a critical regulator of reproductive function. The kisspeptins are potent stimulators of the hypothalamic-pituitary-gonadal (HPG) axis via their actions ongonadotropin-releasing hormone. Therefore, kisspeptins represent putative drug targets for...

In mammals, the adipose organ is composed of white adipocytes (primary site in energy storage) and of brown adipocytes (specialized in thermogenesis). Adipocytes arise from mesenchymal stem cells (MSCs) by a sequential pathway of differentiation. MSCs develop either from ectoderm or mesoderm and com...

We postulate that the increased inflammatory response and NF-kappaB activation promote uterine contractility via 1) direct activation of contractile genes (e.g. COX-2, oxytocin receptor, and connexin 43) and 2) impairment of the capacity of PR to mediate uterine quiescence. PR function near term may...
