Health supplements with regard to nonalcohol-related greasy lean meats illness: a system meta-analysis.
The indirect genetic effects of fathers on the expression and evolution of female reproductive traits in the wild is not well understood. In a wild population of great tits (Parus major), Evans et al. estimated the genetic and nongenetic effects of male mates on two female reproductive traits, lay date and clutch size. The estimated heritability of lay date (but not of clutch size) was increased by 1.5 times after accounting for male indirect genetic effects. This finding illustrates the importance of considering the effects of social partners in classic quantitative genetic models.C1q/TNF-related protein 12 (CTRP12) is an antidiabetic adipokine whose circulating levels are reduced in obesity and diabetes. Although partial and complete loss-of-function mouse models suggest a role for CTRP12 in modulating lipid metabolism and adiposity, its effect on cellular lipid metabolism remains poorly defined. Here, we demonstrate a direct action of CTRP12 in regulating lipid synthesis and secretion. In hepatoma cells and primary mouse hepatocytes, CTRP12 treatment inhibits triglyceride synthesis by suppressing glycerophosphate acyltransferase (GPAT) and diacylglycerol acyltransferase (DGAT) expression. CTRP12 treatment also downregulates the expression of hepatocyte nuclear factor-4α (HNF-4α) and its target gene microsomal triglyceride transfer protein (MTTP), leading to reduced very-low-density lipoprotein (VLDL)-triglyceride export from hepatocytes. Consistent with the in vitro findings, overexpressing CTRP12 lowers fasting and postprandial serum triglyceride levels in mice. These results underscore the important function of CTRP12 in lipid metabolism in hepatocytes.The concentration of bone marrow (BM) aspirate (BMA) is increasingly valued for bone and cartilage repair, particularly with the rarity and donor-variability of BM-multipotential stromal cells (BM-MSCs). The present study aimed to assess BM-MSC yield following BM concentration using a fast and compact-sized vertical centrifugation system. BMA concentrate (BMAC) was separated in a 1 min process and collected easily after an automatic discarding of plasma and red blood cells. A significant increase in CD45low CD271high cells per BMAC volume (measured using flow-cytometry) was noted (4-fold, p = 0.0001). Additionally, the vertical centrifugation system helped to enrich colony numbers (assessed by CFU-F assays) in BMAC comparably with conventional centrifugation systems, BioCUE™ and SmartPReP-2® (4.3-fold, 4.6-fold and 3-fold, respectively). Next, a functional assessment of BM-MSCs processed by vertical centrifugation was performed, and MSC viability and proliferation were not affected. Also, these BM-MSCs showed similar alkaline phosphatase and calcium levels to those of BMA-MSCs when osteogenically induced. Furthermore, glycosaminoglycans and Nile red levels in addition to the gene expression assays confirmed that there was no significant change in chondrogenic or adipogenic abilities between BMA-MSCs and BMAC-MSCs. The expression levels of selected angiogenic and immunomodulatory mediators were also similar between the two groups. Collectively, the vertical centrifugation system helped to enrich BM-MSCs effectively, while maintaining cell viability and functions. Thus, such a vertical centrifugation system for BM concentration can be valuable for various regenerative therapies.The aim of this study is to investigate the effect of lncRNA DUXAP8 on proliferation and apoptosis of ovarian cancer cells, and to explore its potential mechanism. DUXAP8 interfering and overexpressing cell lines were constructed and the cell proliferation and apoptosis were tested. Hematoxylin-eosin, TdT-mediated dUTP nick end labeling, and immunohistochemistry were used to detect the effect of DUXAP8 on the ability of tumor formation. Quantitative real-time polymerase chain reaction and western blot were used to detect the mRNA and protein expression of miR-590-5p and YAP1, respectively. Dual luciferase assay was used to determine the target relationship between DUXAP8, miR-590-5p, and YAP1. DUXAP8 interference and miR-590-5p down-regulated cell lines were further constructed. Compared with normal ovarian cells, the expression of DUXAP8 in ovarian cancer cells was significantly increased, while the expression of miR-590-5p was decreased (p  less then  0.05). After DUXAP8 interference, cell proliferation and colony formation were decreased, and apoptosis was increased. The results of in vivo experiment are consistent with the in vitro experiments. check details The expression of miR-590-5p was up-regulated and the expression of YAP1 was decreased after DUXAP8 interference. Moreover, miR590-5p inhibitor can attenuate the effect of DUXAP8 interference on ovarian cancer cells. Taken together, lncRNA DUXAP8 can regulate the proliferation and apoptosis of ovarian cancer cells, and its mechanism may be related to the regulation of YAP1 gene by targeting miR-590-5p.An emerging concept is that the hypothalamic nutrient sensor can regulate peripheral energy metabolism via a brain-liver circuit. Valine is an essential branched-chain amino acid (BCAA) that drives intracellular signaling cascades by the activation of target of rapamycin complex 1 (TORC1) which is critical to protein metabolism in mammals. However, in teleost fish, it remains scarce in this area especially about how the intraventricular (ICV) injection of valine can mediate the protein metabolism in peripheral organs. This study would tentatively explore the effects of ICV injection of valine on protein metabolism in peripheral organs through evaluating the postprandial ammonia-N excretion rate in Chinese perch. The control group was injected with 5-μL PBS, and the Val group was injected with 20-μg L valine dissolved into 5-μL PBS. The ammonia-N excretion rate of Val group was lower than control group at 4-, 12-, and 24-h postinjection, while the concertation of plasma glucose was increased sharply at 0.5-, 4-, 12-, and 24-h postinjection. We further checked both mRNA level and the enzyme activity of glutamate dehydrogenase (GDH) in the liver and adenosine monophosphate deaminase (AMPD) in muscle, and we found that they were obviously decreased in Val group at 4-, 12-, and 24-h postinjection. The phosphorylation level of ribosomal protein S6, a downstream target protein of TORC1, was markedly enhanced in the liver of Val group at 4-, 12-, and 24-h postinjection. Collectively, these results illustrated that ICV injection of valine can attenuate protein degradation in peripheral organs by depressing the GDH and AMPD enzyme activity; on the other hand, the injected valine can trigger the activation of TORC1 in the liver via a brain-liver circuit and then interdict proteolysis.
