BACKGROUND Epidemiological studies have reported that the prevalence of diabetes in women > 40 years of age, especially those in the postmenopausal phase, was higher than in men in areas with high levels of arsenic in drinking water. The detailed effect of arsenic on glucose metabolism/homeostasis in the postmenopausal condition is still unclear. OBJECTIVES We investigated the effects of arse...

The sarco(endo)plasmic reticulum Ca2+ ATPase (SERCA) actively transports into the sarcoplasmic to facilitate cardiac muscle relaxation. Phospholamban (PLN) allosterically inhibits SERCA, and an imbalance of SERCA2a, dominant isoform, PLN content disrupts homeostasis contractility. A previous study has shown that ovariectomized (OVX) rats have reduced SERCA activity due lowered SERCA2a increased...

background: the uterus is a dynamic tissue responding to hormonal changes during reproductive cycles. as such, uterine stem cells have been studied in recent years. transcription factors oct4 and sox2 are critical for effective maintenance of pluripotent cell identity. objective: the present research evaluated the mrna expression of oct4 and sox2 in the uterine tissues of ovariectomized mice tr...

Generalized osteoporosis in postmenopausal rheumatoid arthritis (RA) is caused both by estrogen deficiency and by the inflammatory disease. The relative importance of each of these factors is unknown. The aim of this study was to establish a murine model of osteoporosis in postmenopausal RA, and to evaluate the relative importance and mechanisms of menopause and arthritis-related osteoporosis. ...

BACKGROUND Endometrial cancer, the most common gynecological cancer, is closely associated with endometrial hyperplasia, unopposed estrogen exposure, and genetic alterations. Phosphatase and tensin homologue (PTEN) is a tumor suppressor genes completely lost or mutated in >50% of primary endometrioid endometrial cancers. Estrogen-dependent endometrioid carcinoma is the most common type of endom...

Patients with chronic myelofibrosis often suffer from osteosclerosis, which is associated bone pain and may lead to marrow failure. The pathogenesis of linked aberrant megakaryocyte development function. Null loss-of-function mutations in MPIG6B, codes for the inhibitory heparan sulfate receptor G6b-B, result severe macrothrombocytopenia, large clusters, focal primary mice humans. We investigat...

The safety and effectiveness were examined of the spirulina alga on bone metabolism in ovariectomized estrogen-deficient rats and hindlimb-unloaded mice. The dosage range was from an amount equal to that recommended in so-called health foods for humans (0.08 g/kg BW/day) to a 100-fold higher dose. The bone mineral density (BMD) of the whole femur and tibia of ovariectomized rats in the any spir...

Asthma is a chronic inflammatory disease that affects more females than males after puberty, and its symptoms and severity in women change during menstruation and menopause. Recently, evidence has demonstrated that interactions among the microbiota, female sex hormones, and immunity are associated with the development of autoimmune diseases. However, no studies have investigated if therapeutic ...

Gonadectomized mice of the ce strain are of interest because they have a high incidence of adrenal cortical carcinomas (2). These tumors are extremely rare in normal mice, as evidenced by observations at the Jackson Memorial Laboratory and by the infrequent references to such growths in the literature. Adrenal cortical carcinomas are themselves of special interest because of evidence that they ...

OBJECTIVE Since the unexpected results from the Women's Health Initiative, the possible protective role of estrogen in preventing heart disease in perimenopausal and postmenopausal women is uncertain. This study examined atherosclerotic lesion development in ovariectomized versus follicle-depleted ovary-intact cholesterol-fed female low-density lipoprotein (LDL) receptor-deficient mice. METHO...
