Functional PRL receptors are expressed in the human endometrium during the secretory phase of the menstrual cycle in which PRL stimulates tyrosine phosphorylation of Janus kinase 2 and STAT (signal transducer and activator of transcription) 1 and 5. In this study, we investigated the effect of PRL on the MAPK/ERK pathway in the human endometrium. Human(More)
Experimental studies in animals have established prolactin (PRL) as a progonadal hormone that promotes the function of the testis and reproductive accessory glands. The present study investigated the localization of PRL receptor (PRL-R) expression in the human testis and accessory tissues. Expression of PRL-R was identified in human testis and vas deferens(More)
CONTEXT Ovarian surface epithelial (OSE) cells express multiple nuclear hormone receptor genes, including those encoding thyroid hormone and estrogen receptors (TR and ER, respectively). Ovarian cancer is hormone-dependent, and epidemiological evidence links hyperthyroidism, inflammation of the ovarian surface, and increased risk of ovarian cancer. (More)
The majority of ovarian cancers (>90%) are believed to derive from the ovarian surface epithelium (OSE); a single layer covering the entire surface of the ovary. At ovulation, the OSE cell layer undergoes an inflammatory response, involving cell death and growth, in order to overcome ovarian surface rupture. Abnormalities during these processes are believed(More)
Ovulation is believed to contribute to the development of ovarian cancers that derive from the ovarian surface epithelium (OSE). The process of ovulation is synonymous with inflammation and inflammatory cytokines such as interleukin-1alpha (IL-1alpha) have recently been shown to induce both inflammatory and anti-inflammatory responses in human OSE (HOSE)(More)
cAMP response-element binding (CREB) transcription factors transduce cell survival responses to peptide hormones and growth factors in normal tissues and mutant CREB proteins are implicated in tumorigenesis. Ovarian cancer most frequently arises from the ovarian surface epithelium (OSE), possibly due to repeat inflammation-associated injury-repair episodes(More)
