Previous studies have demonstrated over-expression of cyclooxygenase-2 (COX-2) enzyme and enhanced synthesis of prostanoids, such as prostaglandin E2 (PGE2), in cervical carcinomas. PGE2 mediates its is effects by interacting with one of four receptors termed EP1-4. Expression and signalling of EP receptors, including EP4, are elevated in cervical carcinomas. We have previously proposed that in addition to endogenous PGE2, EP recepto...

Previously we have demonstrated up-regulated expression of COX-2 and enhanced synthesis of PGE2 in cervical carcinomas. (Sales et al. 2001. J. Clin. Endocrinol Metab. 86(5):2243-2249). Enhanced PGE2 synthesis as a consequence of COX-2 overexpression has been associated with various carcinomas and is regarded as a promoter of neoplastic cell proliferation and angiogenesis. In sexually active women growth and invasiveness of neoplastic cervical cells may be...

Prostaglandin F2a (PGF) receptor (FP) expression is up-regulated in neoplastic epithelial and perivascular cells in endometrial adenocarcinomas, indicating potential regulation of vascular function by PGF via the FP receptor. This study investigated the potential role of PGF-FP receptor signalling in modulating vascular function in endometrial adenocarcinomas.Endometrial biopsies were obtained in accordance with Ethics Committee guidance with ...

Prostaglandin F2a (PGF) is biosynthesised by cyclooxygenase (COX) enzymes and mediates its activity following FP receptor activation. Recently, we have shown elevated FP receptor expression and signalling in endometrial adenocarcinomas. This study investigated FP receptor signalling in human endometrial adenocarcinoma (Ishikawa) cells.Ishikawa cells were stably transfected with FP receptor cDNA in the sense (FPS) and antisense (FPAS) orientati...

Prostaglandin (PG) E2 has been implicated in benign and neoplastic endometrial pathologies. PGE2 exerts its function by coupling to 4 subtypes of G protein coupled receptors (EP1-EP4). Recently a role for the EP2 receptor in angiogenesis has been established. This study investigated signal transduction and vascular endothelial growth factor (VEGF) expression by the EP2 receptor in Ishikawa endometrial epithelial cells. Ishikawa cells were stably transfect...

Abstract: Congenital hypogonadotropic hypogonadism (CHH) is characterized by isolated GnRH deficiency in the absence of central anatomical causes. Classically considered to be a permanent disorder, CHH reversal has been reported in up to 15% of cases. However, reversal may not always be life-long, as hypogonadism relapse can occur in a subset of patients. Criteria for reversal normalization of circulating sex steroids, and spontaneous fertility. We report a 26-yrs-old man, who...

Recent studies have suggested that upper body adiposity is associated with major cardiovascular risk (CVR). However most of them were conducted in obese patients. This study aimed to evaluate the relationship of neck circumference (NC) in a non-obese Brazilian adult population, considering that it would be a simple and time-saving measurement to identify patients with worse cardiometabolic profile. We evaluated 279 non-obese Brazilian adults [86 men (♂), 193 women (&#979...
