Juvenile hormone (JH) plays an essential role in regulating molting, metamorphosis, reproduction, and diapause (dormancy), in many insects and crustaceans. JH esterases (JHEs) can control JH titer by regulating JH degradation. Although the biochemistry and structure of JHEs have been well studied, regulation of their expression remains unclear. We identified three putative JHEs (JHE1, JHE2, JHE3)...
Diapause (also known as dormancy) is a state of arrested development induced by photoperiod or temperature that allows insects to survive adverse environmental conditions. By regulating diapause induction, the circadian clock is involved in short-day-induced winter diapause but whether this is also the case in long-day (LD)-induced summer diapause remains unknown. The cabbage beetle Colaphellus bowringi...
Accumulating evidence has indicated that microRNAs (miRNAs) and endoplasmic reticulum (ER) stress play critical roles in myoblast differentiation. However, the regulation roles of miRNAs and ER stress in myogenic differentiation have not been fully revealed and need to be further studied. Here, we discovered that the expression levels of miR-181a-5p were strongly upregulated during C2C12 cell differentiation...
In our previous study we screened thousands of lncRNAs for their relationship with ventricular septal defect. Among these lncRNAs, uc.167 attracted our attention for its high level of conservation and that it was antisense to the Mef2c gene, which encodes myocyte enhancer factor 2C. This study aims to investigate the role of uc.167 during cardiomyocyte maturation in P19 cells induction and possible...
To determine the origin and evolution of goose parvovirus (GPV) and Muscovy duck parvovirus (MDPV) in the Mainland of China, phylogenetic and recombination analyses in the present study were performed on 32 complete VP1 gene sequences from China and other countries. Based on the phylogenetic analysis of the VP1 gene, GPV strains studied here from Mainland China (PRC) could be divided into three genotypes,...
Melanocortin receptor 1 (MC1R), Agouti signaling protein (ASIP), and Tyrosinase-related protein 1 (TYRP1) are reported critical genes that regulate pheomelanin and eumelanin synthesis in mammals. Liangshan pig is a special Chinese indigenous pig breed with two completely different coat colors, solid black and blond. In this study, we detected polymorphisms of the above three genes and assessed the...
MicroRNAs (miRNAs) are small, non-coding RNAs, which are involved in regulation of a variety of biological processes. Since previous studies regarding the role of miRNAs in the regulation of adipogenic differentiation have shown that miRNA-27a, one member of miRNA-23a∼27a∼24 cluster, could suppress adipogenesis. We now investigated whether miRNA-23a regulates adipogenic differentiation. In the present...
Lipoprotein lipase (LPL) is a key enzyme in lipid metabolism and is transported by glycosylphosphatidylinositol-anchored high-density lipoprotein-binding protein 1 (GPIHBP1) from the interstitial spaces to the capillary lumen. Here, we cloned a cDNA and the genomic locus of the porcine GPIHBP1 gene, and investigated its tissue expression pattern and its genetic effects on adipose traits. Porcine GPIHBP1...
DEAD-box proteins comprise a large protein family. These proteins function in all types of processes in RNA metabolism and are highly conserved among eukaryotes. However, the precise functions of DEAD-box proteins in rice physiology and development remain unclear. In this study, we identified a rice DEAD-box protein, OsRH17, that contains a DEAD domain and all of the common conserved motifs of DEAD-box...
Adipose triglyceride lipase (ATGL), catalyzing the initial step of hydrolysis of triacylglycerol (TAG) in adipocytes, has been known to be inhibited by G0/G1 switch protein 2 (G0S2). In this study, we determined tissue expression pattern and polymorphism of G0S2 gene in porcine. The results showed that the G0S2 transcript levels were very high in the liver and, to a lesser degree, in adipose tissues...
MicroRNAs (miRNAs) are directly involved in cancer initiation, progression and metastasis. Alterations of miRNAs expression in cancer tissue may be reflected in circulation. We attempted to investigate the expression and clinical significance of plasma miR-20a, miR-31 and miR-375 in patients with non-small cell lung cancer (NSCLC). The plasma levels of miR-20a, miR-31 and miR-375 in 164 NSCLC patients...
Somatic cell-mediated transgenesis is routinely used to transfer exogenous genes to livestock genomes. However, transgene insertion events are essentially random which may lead to transgene silencing or alter animal phenotype because of insertional mutagenesis. To overcome these problems, we established a gene manipulation system in goat somatic cells based on homologous recombination and flp recombinase-mediated...
