Myocardin is regarded as a key mediator for the change of smooth muscle phenotype. The gap junction protein connexin 43 (Cx43) has been shown to be involved in vascular smooth muscle cells (VSMCs) proliferation and the development of atherosclerosis. However, the role of myocardin on gap junction of cell communication and the relation between myocardin and Cx43 in VSMC phenotypic switch has not been...
The sex of relatively primitive animals such as invertebrates is mostly determined by environmental factors and chromosome ploidy. Heteromorphic chromosomes may also play an important role, as in the ZW system in lepidopterans. However, the mechanisms of these various sex determination systems are still largely undefined. In the present study, a Masculinizer gene (Ar-Masc) was identified in the crustacean...
This study aimed to investigate the correlations of three common single nucleotide polymorphisms (SNPs) in the PTEN gene (rs701848 T>C, rs2735343 G>C and rs112025902 A>T) with the risk of depression and depressive symptoms in a Chinese population.From July 2011 to June 2013, a total of 384 patients with depression and 400 healthy individuals were included in this study. These SNPs in the...
To elucidate the effects of rice protein on the detoxification and antioxidant defense via the Nuclear factor erythroid 2-related factor 2 (Nrf2) pathway, adult rats were fed casein and rice protein under cholesterol-free and -enriched dietary conditions. Nrf2 proteins and gene expressions were stimulated by rice proteins with respect to caseins accompanied by up-regulating the expression of gene...
Taxol (paclitaxel) is one of the taxane class of anticancer drugs as a first-line chemotherapeutic agent against many cancers including colorectal cancer, breast cancer, non-small cell lung cancer, ovarian cancer and so on. It is verified to induce cytotoxicity in a concentration and time-dependent manner. Numerous novel formulations of Taxol have been remanufactured for better therapeutic effect...
In vascular plants, heat shock transcription factors (Hsfs) regulate heat stress response by regulating the expression of heat shock proteins. This study systematically and comprehensively analyzed the Hsf family in tea plant [Camellia sinensis (L.) O. Kuntze]. A total of 16 CsHsfs were identified from the transcriptome database of tea plant and analyzed for their phylogenetic relationships, motifs,...
The signal transducer and activator of transcription 5a (Stat5a) modulates genes involved in proliferation and survival and plays pivotal roles in regulating the function of the mammary gland during pregnancy, lactation, and involution. However, there is little information about the effects of Stat5a on apoptosis of goat mammary gland epithelial cells (GMECs). In addition, parathyroid hormone-related...
ΔFosB is a member of the family of transcription factor activating proteins-1 (AP-1) and is known to play important roles in Ca2+ metabolism processes of osteoblast formation and differentiation in humans and rodents. The postpartum mammary gland is one of the significant organs for Ca2+ metabolism processes. However, very little information is available on the role of ΔFosB in goat mammary gland...
MicroRNAs (miRNAs) have been reported to be aberrantly expressed in patients with cancer. Many studies have shown that circulating miRNAs could play potential roles as diagnostic and prognostic biomarkers of cancers. The aim of this meta-analysis is to summarize the role of circulating miR-21 as a biomarker in patients with a variety of carcinomas.Eligible studies were identified and assessed for...
Xq28 duplications encompassing the methyl CpG binding protein 2 (MECP2) in males exhibit a distinct phenotype, including developmental delay, facial dysmorphism, muscular hypotonia, intellectual disability, poor or absent speech, recurrent infections and early death. The vast majority of affected males inherit the MECP2 duplication from their usually asymptomatic carrier mothers. Only a few cases...
Amanita exitialis is a lethal mushroom that was first discovered in Guangdong Province, China. The high content of amanitin in its basidiocarps makes it lethal to humans. To comprehensively characterize the A. exitialis transcriptome and analyze the Amanita toxins as well as their related gene family, transcriptome sequencing of A. exitialis was performed using Illumina HiSeq 2000 technology. A total...
MicroRNAs (miRNAs) are a group of endogenous, small, noncoding RNAs that function as key post-transcriptional regulators. miRNAs are involved in many biological processes including apoptosis. In this study, mouse miR-702 (mmu-miR-702), a mirtron derived from the 13th intron of the Plod3 gene, was identified as a regulator of anti-apoptosis. mmu-miR-702 was down-regulated after treatment with the apoptosis-inducer...
The effect of mouse resistin on hepatic insulin resistance in vivo and in vitro, and its possible molecular mechanism were examined. Focusing on liver glycogen metabolism and gluconeogenesis, which are important parts of glucose metabolism, in primary cultures of rat hepatocytes we found that glycogen content was significantly lower (P<0.05) after treatment with recombinant murine resistin only...
To investigate the role of liver-specific expression of glucokinase (GCK) in the pathogenesis of hyperglycemia and to identify candidate genes involved in mechanisms of the onset and progression of maturity onset diabetes of the young, type 2 (MODY-2), we examined changes in biochemical parameters and gene expression in GCK knockout (gck w/– ) and wild-type (gck w/w ) mice as they...
Nucleobindin 2 (NUCB2) is a precursor of nesfatin-1, a hypothalamic anorectic neuropeptide. The association between variants of the NUCB2 gene and adiposity was examined. 142 severely obese Chinese children in Singapore, and 384 normal weight Chinese children from a longitudinal cohort from Da Qing, China, were studied. NUCB2 was screened using PCR and direct sequencing in 29 severely obese children...
The X-linked form of Alport syndrome is associated with mutations in the COL4A5 gene, which is located at Xq22.3 and encodes the α5 chain of type IV collagen. Here we clinically characterized a Chinese family with Alport Syndrome, but no ocular or hearing abnormalities have been observed in any patient in the family. Through Linkage analysis and direct DNA sequencing, a novel complex deletion/insertion...
The present study was designed to investigate the underlying molecular mechanism for Angiotensin II type 1 receptor blockers (ARBs) mediated cardio-protection against pressure overload-induced cardiac remodeling with a focus on Smad7. ROCK-1, Smad3 and fibronectin expressions were increased in male C57BL/6 mice underwent transverse aortic constriction (TAC) for 2weeks. Treatment with Candesartan (2mg/kg...
MicroRNAs (miRNAs) are involved in the development of most cancers. However, few studies have been conducted to determine their relationship to biliary tract cancer (BTC). Farnesoid X receptor (FXR) has been reported to be a tumor suppressor for hepatocellular carcinoma and breast cancer; but few studies have focused on its correlation with BTC. In this study, we identified miR-421 as a potential...
The primary structure of the 3 -5 exonuclease (Exo) site of the Gram + bacterial DNA polymerase III (Pol III) was examined by site-directed mutagenesis of Bacillus subtilis Pol III (BsPol III). It was found to differ significantly from the conventional three-motif substructure established for the Exo site of DNA polymerase I of Escherichia coli (EcPol I) and the majority of other DNA polymerase-exonucleases...
