Maternal malnutrition lead to the incidence of metabolic diseases in offspring. The purpose of this project was to exam whether maternal low chromium could disturb normal lipid metabolism in offspring, altering adipose cell differentiation and leading the incidence of lipid metabolism diseases, including metabolic syndrome and obesity. Female C57BL mice were given a control diet (CD) or a low chromium diet (LCD) during the gestational and lactation periods. After weaning, offspring was fed with CD or LCD. The female offspring were assessed at 32 weeks of age...

Spermatogenic lineage has been directly generated in spermatogonial stem cell (SSC) conditions from human pluripotent stem cells (PSCs). However, it remains unknown whether mouse ESCs can directly differentiate into advanced male germ cell lineage in the same conditions. Here, we showed that rather low efficiency of germ-like cell generation from mouse ESCs in SSC conditions. Interestingly, addition of retinoic acid (RA) into SSC conditions enabled efficient differentiation of mouse ESCs into germ-like cells, as shown by activating the expression of spermatogenesis-associated genes during differentiation process, such as Mvh , Dazl , Prdm14 , Stella , Scp1 , Scp3 , Stra8 and Rec8 In contrast, for cells cultured in control medium, the activation of these above genes barely occurred...

This study aims to investigate the effects of microRNA-146a (miR-146a) on the proliferation and apoptosis of human osteoarthritis (OA) chondrocytes by targeting TRAF6 through NF-κB signaling pathway. Human normal and OA chondrocytes were selected and divided into the normal group, blank group, negative control (NC) group, miR-146a mimics group, miR-146a inhibitors, miR-146a inhibitor + si-TRAF6 group and si-TRAF6 group. Quantitative real-time polymerase chain reaction (qRT-PCR) was applied to detect the expressions of miR-146a, TRAF6 mRNA and NF-κB mRNA...

We recently found that integrin αvβ3 binds to FGF1, and that the integrin-binding defective FGF1 mutant (Arg-50 to Glu, R50E) is defective in signaling and antagonistic to FGF1 signaling. R50E suppressed angiogenesis and tumor growth, suggesting that R50E has potential as a therapeutic. However, FGF1 is unstable, and we had to express R50E in cancer cells for xenograft study, since injected R50E may rapidly disappear from circulation. We studied if we can develop antagonist of more stable FGF2. FGF2 is widely involved in important biological processes such as stem cell proliferation and angiogenesis...

   The association between dietary carbohydrate intake and colorectal cancer risk remains controversial. We therefore conducted this meta-analysis to assess the relationship between them. A literature search from the databases of Pubmed, Embase, Web of science and Medline databases were performed for available articles published in English (up to Sep 2016). Pooled relative risk (RR) with 95% confidence interval (CI) was calculated to evaluate the association between dietary carbohydrate intake and colorectal cancer risk...

This study aimed to compare the effect of autograft or allograft anterior cruciate ligament (ACL) reconstruction on the expressions of LOXs and MMPs in a New Zealand white rabbit model. New Zealand white rabbits were divided randomly into control, sham, autograft and allograft groups At the 4th and 8th week after operation, biomechanical testing was performed to measure the primary length, cross-sectional area, maximum tensile load and stiffness of ACL, and HE staining was used to observe cell morphology and fibre alignment of ACL...

Intestinal epithelial cells are the targets for transmissible gastroenteritis virus (TGEV) infection. It is urgently to develop a novel candidate against TGEV entry. Bacillus subtilis is a probiotics with excellent anti-microorganism properties, and one of its secretions, surfactin, has been regarded as the versatile weapons for most plant pathogens, especially for the enveloped virus. We demonstrate for the first time that Bacillus subtilis OKB105 and its surfactin can effectively inhibit one animal coronavirus, TGEV, entering the intestinal porcine epithelial cell line (IPEC-J2)...

The tumor microenvironment which is a highly heterogeneous entity plays crucial roles in cancer progression. As the most prominent stromal cell types, cancer-associated fibroblasts (CAFs) produce a variety of factors into the tumor microenvironment. In this study, we firstly isolated CAFs from tumor tissues of the patients with ovarian cancer and demonstrated that hepatocyte growth factor (HGF) was highly expressed in the supernatant of CAFs. CAF-derived HGF or human recombinant HGF promoted cell proliferation in human ovarian cell lines SKOV3 and HO-8910 cells...

Chondrocytes which are embedded within the growth-plate or the intervertebral discare sensitive to environmental stresses, such as inflammation and hypoxia. However, little is known about the molecular signaling pathways underlining the hypoxia-induced mitochondrial dysfunction and apoptosis in chondrocytes. In this study, we firstly examined the hypoxia-induced apoptosis, mitochondrial dysfunction and the activation of cAMP response element-binding protein (CREB) signaling in human chondrocyte cell line, C28/I2, and then investigated the regulatory role of RhoA, a well-recognized apoptosis suppressor, in such process, with gain-of-function strategy...

Diabetic Nephropathy (DN) is the leading cause of end-stage renal disease, characterized by progressive albuminuria and conferring additional risk of cardiovascular disease and mortality. The crucial role of heat-shock proteins (HSPs) on renal function in patients with DN has been well documented. This study was aimed to understand the association of HSP-70 gene variants on the susceptibility of type 2 diabetes mellitus (T2DM) and DN. A total of 946 subjects (549M; 397F) were recruited and divided into four groups according to the levels of urinary albumin excretion (UAE): those with normoalbuminuria (UAE300 mg/24 hour; n=230)...

Recently, autophagy has been indicated to play an essential role in various biological events, such as the response of cervical cancer cells to chemotherapy. However, the exact signaling mechanism that regulates autophagy during chemotherapy remains unclear. In this study, we investigated the regulation by Cisplatin on Protein kinase C beta (PKC β), on B-cell lymphoma 2 (Bcl-2) and on apoptosis in cervical cancer Hela cells. And then we examined the regulation by Cisplatin on autophagy and the role of autophagy on the chemotherapy in Hela cells...

Aberrant expression of Fos-related antigen-1 (Fra1) is commonly elevated in various malignant cancers and is strongly implicated in invasion and metastasis. However, the molecular mechanisms underlying its dysregulation in human glioma remain poorly understood. In the present study we demonstrate that upregulation of Fra1 plays a crucial role in the glioma aggressiveness and epithelial-mesenchymal transition activated by Wnt/β-catenin signal pathway. In glioma cells, activation of Wnt/β-catenin signaling by Wnt3a administration obviously induced epithelial-mesenchymal transition (EMT) and directly activated the transcription of Fra1...

Recent epidemiological and clinical studies have shown that type 2 diabetic patients can develop diabetic vascular complications even after intensive glycemic control. It has been suggested that this phenomenon could be explained by the hypothesis of "metabolic memory". The underlying mechanisms between these enduring effects and the prior hyperglycemic state are still not well understood. Preliminary studies demonstrate that hyperglycemia can regulate gene expression by epigenetic modifications, such as DNA methylation, which can persistently exist even after glucose normalization...
