Vaspin, visceral adipose tissue-derived serine protease inhibitor, is involved in the development of obesity, insulin resistance, inflammation and energy metabolism. Our previous study showed vaspin expression and its regulation in the ovary; however, the role of this adipokine in ovarian cells has never been studied. Here, we studied in vitro the effect of vaspin on various kinase signaling pathways mitogen-activated kinase (MAP3/1), serine/threonine kinase (AKT), signal transducer and activator of transcription 3 (STAT3) protein kinase AMP (PRKAA1), protein kinase A (PKA) and on expression of nuclear factor kappa B (NFKB2) as well as on steroid synthesis by porcine ovarian cells. By Western blot, we found that vaspin (1 ng/ml), in a time-dependent manner, increased phosphorylation of MAP3/1, AKT, STAT3, PRKAA1 and PKA, while it decreased expression of NFKB2. We observed that vaspin, in a dose-dependent manner, increased basal steroid hormones secretion (progesterone and estradiol), mRNA and protein expression of steroid enzymes using real-time PCR and Western blot, respectively, and the mRNA of gonadotropins (FSHR, LHCGR) and steroids (PGR, ESR2) receptors. The stimulatory effect of vaspin on basal steroidogenesis was reversed when ovarian cells were cultured in the presence of a PKA pharmacological inhibitor (KT5720) and when GRP78 receptor was knocked down (siRNA). However, in the presence of insulin-like growth factor type 1 and gonadotropins, vaspin reduced steroidogenesis. Thus, vaspin, by activation of various signaling pathways and stimulation of basal steroid production via GRP78 receptor and PKA, could be a new regulator of porcine ovarian function. © The Author(s) 2020.

This study examines predictors of transition to different stages of hypertension - incidence of hypertension, incidence of prehypertension, and incidence of prehypertension to hypertension. METHODS Population based survey data from the Birbhum Population Project, located in West Bengal, India was used. A cohort of 8977 individuals (male 3934, female 5043), participated in the 2012-13 survey, and were followed up for resurvey in 2017-18. The Seventh Report of the Joint National Committee (JNC 7) guidelines were followed to define hypertension. Bivariate and multivariate Poisson regression analyses were conducted to attain the study objective. RESULTS The incidence of hypertension, prehypertension among males (7.9% and 45.3%, respectively) is higher than that among females (5.9% and 32.7%, respectively). However, the incidence of prehypertension to hypertension is lower among males (23.6%) than among females (33.6%). Among both sexes, with age, the incidence of hypertension, and incidence of prehypertension to hypertension appeared to increase, whereas incidence of prehypertension among females increased with age. Findings indicate a diverse gradient of socioeconomic, behavioral, and anthropometric characteristics influencing the incidence of different stages of hypertension. CONCLUSION With a focus on females and the richest individuals, this study proposes that an appropriate intervention be designed in keeping with the socioeconomic, behavioral gradient of incidence of different stages of hypertension. The role of anthropometric indicators in hypertension is proposed to be further studied for better population based screening. © American Journal of Hypertension, Ltd 2020. All rights reserved.

METHODS The neurological deficits of the rats were analyzed and HE staining was performed. BMS-986365 in vivo The cerebral infarct volume was calculated by means of TTC staining, and neuronal apoptosis was detected by TUNEL staining. At the same time, the contents of glutathione peroxidase, glutathione, superoxide dismutase, nitric oxide, and malondialdehyde in brain tissue were measured. The expression of the relevant protein was detected by means of Western blotting. RESULTS The results showed that the neurological deficit score and infarct area of the I/R rats in the soy sterol treatment group were significantly lower than those in the I/R group. Moreover, the levels of carbon monoxide and malondialdehyde in the soysterol group were significantly lower than those in the I/R group, and the expressions of cyclooxygenase-2 (Cox-2) and NF-kappa B (p65) in the soysterol group were also significantly lower than those in the I/R group. The expression of Nrf2 (nucleus) and heme oxygenase-1 (HO-1) increased significantly, and the activities of antioxidant enzymes and superoxide dismutase (SOD) were increased. In addition, the stigmasterol treatment can inhibit apoptosis, down-regulate Bax and cleaved caspase-3 expression, and up-regulate Bcl-Xl expression. CONCLUSION Stigmasterol protects the brain from brain I/R damage by reducing oxidative stress and inflammation.

This study was conducted to explore a novel regulatory network of lncRNA XIST in LSCC cells. MATERIALS AND METHODS Quantitative real-time polymerase chain reaction (QRT-PCR) was used to detect the expression levels of XIST, miR-125b-5p and TRIB2 in LSCC cells and tissues. Cell proliferation, apoptosis, migration and invasion were detected by Cell counting Kit-8 (CCK-8), flow cytometry and Transwell assays, separately. The relationship among XIST, miR-125b-5p and tribbles homolog 2 (TRIB2) was predicted by starBase v2.0 or TargetScan and confirmed by Dual-luciferase reporter assay. The TRIB2 protein expression was quantified by Western blot assay. Murine xenograft model was utilized to validate the role of XIST in vivo. RESULTS XIST was notably up-regulated in LSCC tissues and cells, and the high level of XIST was associated with the low survival rate of LSCC patients.
