Changes in gut microbiota (GM) are closely associated with metabolic syndrome, obesity, type 2 diabetes and so on. Several medicinal herbs, including Ephedra sinica (Es), have anti-obesity effects that ameliorate metabolic disorders. Therefore, in this study we evaluated whether Es maintains its anti-obesity effect through Es-altered gut microbiota (EsM) transplantation. GM was isolated from cecal contents of Es treated and untreated rats following repeated transplants into obese rats via oral gavage over three weeks...

Metabolic endotoxemia originating from dysbiotic gut microbiota has been identified as a primary mediator for triggering the chronic low-grade inflammation (CLGI) responsible for the development of obesity. Capsaicin (CAP) is the major pungent bioactivator in chili peppers and has potent anti-obesity functions, yet the mechanisms linking this effect to gut microbiota remain obscure. Here we show that mice fed a high-fat diet (HFD) supplemented with CAP exhibit lower levels of metabolic endotoxemia and CLGI associated with lower body weight gain...

BACKGROUND: The obesity epidemic has significantly increased the incidence and severity of hepatic steatosis in liver surgery patients and liver donors, potentially impacting postoperative liver regeneration and function. Development of a non-invasive means to quantify hepatic steatosis would facilitate selection of candidates for liver resection and transplant donation. METHODS: An IRB-approved protocol prospectively enrolled 28 patients with liver tumors requiring hepatic resection...

Recent studies implicate the Cyr61, CTGF, Nov (CCN) matricellular signaling protein family as emerging players in vascular biology, with NOV (alias CCN3) as an important regulator of vascular homeostasis. Herein, we examined the role of CCN3 in the pathogenesis of atherosclerosis. In response to a 15-week high-fat diet feeding, CCN3-deficient mice on the atherosclerosis-prone Apoe(-/-) background developed increased aortic lipid-rich plaques compared to control Apoe(-/-) mice, a result that was observed in the absence of alterations in plasma lipid content...

Non-alcoholic fatty liver disease (NAFLD), the most common liver disease, is characterized by accumulation of fat (>5% of the liver tissue), in the absence of alcohol abuse or other chronic liver diseases. It is closely related to the epidemic of obesity, metabolic syndrome or type 2 diabetes mellitus (T2DM). NAFLD can cause liver inflammation and progress to non-alcoholic steatohepatitis (NASH), fibrosis, cirrhosis or hepatocellular cancer (HCC). Nevertheless, cardiovascular disease (CVD) is the most common cause of death in NAFLD/NASH patients...

Ubiquitin-specific protease 34 (USP34) is a deubiquitinating enzyme that regulates Axin stability and plays a critical role in Wnt/β-catenin signaling. We sought to investigate the role of USP34 on epithelial-mesenchymal (EMT) induction and its effects on mammary epithelial stem cells. USP34 expression levels were relatively lower in MDA-MB-231 and 4T1 mesenchymal-like cells when compared to epithelial-like cells. Inhibition of USP34 in NMuMG cells induced EMT, as evidenced by the upregulation of EMT markers including N-cadherin, phospho-Smad3, Snail and active-β-catenin, as well as the downregulation of Axin 1 and E-cadherin...

Non-alcoholic steatohepatitis (NASH) is an epidemic metabolic disease with limited therapeutic strategies. Cumulative data support the pivotal role of gut microbiota in NASH. Here, we investigated the hypothesis regarding whether fecal microbiota transplantation (FMT) is effective in attenuating high-fat diet (HFD)-induced steatohepatitis in mice. Mice were randomized into control, HFD and HFD + FMT groups. After an 8-week HFD, FMT treatment was initiated and carried out for 8 weeks. The gut microbiota structure, butyrate concentrations of the cecal content, liver pathology and intrahepatic lipid and cytokines were examined...

OBJECTIVE: A disintegrin and metalloproteinase ADAM17 (tumor necrosis factor-α [TNF]-converting enzyme) regulates soluble TNF levels. We tested the hypothesis that aging-induced activation in adipose tissue (AT)-expressed ADAM17 contributes to the development of remote coronary microvascular dysfunction in obesity. APPROACH AND RESULTS: Coronary arterioles (CAs, ≈90 µm) from right atrial appendages and mediastinal AT were examined in patients (aged: 69±11 years, BMI: 30...

OBJECTIVE: Mice with adipocyte-specific inactivation of low-density lipoprotein receptor-related protein-1 (LRP1) are resistant to diet-induced obesity and hyperglycemia because of compensatory thermogenic response by muscle. However, the physiological function of LRP1 in mature adipocytes and its role in cardiovascular disease modulation are unknown. This study compared perivascular adipose tissues (PVAT) from wild-type (adLrp1(+/+)) and adipocyte-specific LRP1 knockout (adLrp1(-/-)) mice in modulation of atherosclerosis progression...

AREG-/- mice demonstrate impaired mammary development and form only rudimentary ductal epithelial trees, however, AREG-/- glands are still capable of undergoing alveologenesis and lactogenesis during pregnancy. Transplantation of AREG-/- mammary epithelial cells into cleared mouse mammary fat pads results in a diminished capacity for epithelial growth (∼15%) as compared to wild type mammary epithelial cells. To determine whether ERα and/or AREG signaling were necessary for non-mammary cell redirection, we inoculated either ERα-/- or AREG-/- mammary cells with non-mammary progenitor cells (WapCre/Rosa26LacZ+ male testicular cells or GFP+ embryonic neuronal stem cells)...

A pandemic of metabolic diseases, consisting of type-2 diabetes, non-alcoholic fatty liver diseases (NAFLD) and obesity, has imposed critical challenges for societies worldwide, prompting investigation of underlying mechanisms and exploration of low cost and effective treatment. In this report, we demonstrate that metabolic disorders in mice generated by feeding with a high-fat diet without dietary vitamin D (HD) can be prevented by oral administration of polycationic amine resin. Oral administration of cholestyramine , but not the control uncharged polystyrene, was able to sequester negatively charged bacterial endotoxin in the gut, leading to (1) reducing plasma endotoxin levels, (2) resolving systemic inflammation and hepatic steatohepatitis,and (3) improving insulin sensitivity...

Experimental bone marrow transplantation (BMT) in mice is commonly used to assess the role of immune cell-specific genes in various pathophysiological settings. The application of BMT in obesity research is hampered by the significant reduction in high-fat diet (HFD)-induced obesity. We set out to characterize metabolic tissues that may be affected by the BMT procedure and impair the HFD-induced response. Male C57BL/6 mice underwent syngeneic BMT using lethal irradiation. After a recovery period of 8 weeks they were fed a low-fat diet (LFD) or HFD for 16 weeks...

BACKGROUND: Cell-assisted lipotransfer has been promisingly applied to restore soft-tissue defects in plastic surgery; however, the harvesting of stromal vascular fraction increases morbidity and poses potential safety hazards. The authors investigated whether adding indomethacin, an antiinflammatory proadipogenic drug, to the fat graft at the time of transplantation would enhance the final graft volume compared with cell-assisted lipotransfer. METHODS: In vitro, human adipose-derived stem cells were cultured in conditioned growth media supplemented with various doses of indomethacin to investigate adipogenesis and the expression of the adipogenic genes...

Maternal obesity is known to predispose offspring to metabolic and neurodevelopmental abnormalities. While the mechanisms underlying these phenomena are unclear, high fat diets dramatically alter intestinal microbiota, and gut microbiota can impact physiological function. To determine if maternal diet-induced gut dysbiosis can disrupt offspring neurobehavioral function, we transplanted high fat diet- (HFD) or control low fat diet-associated (CD) gut microbiota to conventionally-housed female mice. Recipient mice were then bred and the behavioral phenotype of male and female offspring was tracked...

The grafting of fat mixed with adipose-derived stem cells (ASCs) is being increasingly applied to compensate for the disadvantages of previous fat grafting methods. Devices that automatically isolate fat stem cells also have recently been developed. ASCs were isolated from the inguinal region of White rabbits using Icellator(®), and the number of cells and their viability were measured. The cell count per fat graft (mL) was adjusted to the following concentrations and subcutaneously transplanted into the back: Control group, Fat + PBS; Fat + ASCs (×0...

White adipose tissue is a remarkably expandable organ with results in the last decade showing that human white adipocytes are continuously turned over during the entire life-span. Data primarily in murine models have demonstrated that adipocytes are derived from precursors present mainly in the perivascular areas of adipose tissue but their precise origin remains unclear. Subsets of cells present in bone marrow display a multipotent differentiation capacity which has prompted the hypothesis that bone marrow-derived cells (BMDCs) may also contribute to the adipocyte pool present in peripheral fat depots...

Progressive Familial Intrahepatic Cholestasis type 2 (PFIC2) is a rare cholestatic disorder diagnosed in infancy or childhood that can lead to severe hepatic fibrosis and liver failure. Mutations in the ABCB11 gene result in a deficiency of the bile salt export protein (BSEP) and accumulation of bile inside the hepatocytes. Hepatocellular carcinoma is another condition associated with severe forms of deletion mutations in the ABCB11 gene. Treatment options including ursodeoxycholic acid biliary diversion have mixed outcomes and some patients require liver transplantation...
