MicroRNA (miRNA) is a sort of endogenous ~20–25 nt non-coding RNAs, and it can regulate a variety of biological events. We found the miR-378 may involve in regulating the muscle development of sheep during our previous research. However, the molecular mechanism of miR-378 regulating myoblast proliferation is still unclear. In this research, we predicted that BMP2 (Bone morphogenetic protein 2) was...
Spermatogenesis involves a series of process including exiting from the mitotic cell cycle, entry into meiosis, completion of complex differentiation programs, and producing spermatozoa. Expression of various genes in an ordered manner, and interactions between various genes and their protein products, primarily controlled at the post-transcriptional level with DEAD-box RNA helicases playing a crucial...
Long non-coding RNAs (LncRNAs) are an important class of widespread molecules involved in diverse biological functions, which are exceptionally expressed in numerous types of diseases. Currently, limited study on LncRNA in rheumatoid arthritis (RA) is available. In this study, we aimed to identify the specifically expressed LncRNA that are relevant to adjuvant-induced arthritis (AA) in rats, and to...
The mevalonate pathway is responsible for the biosynthesis of many essential molecules important in insect development, reproduction, chemical communication and defense. Based on Leptinotarsa decemlineata transcriptome and genome data, we identified ten genes that encoded acetoacetyl-CoA thiolase (LdAACT1 and LdAACT2), hydroxymethylglutaryl (HMA)-CoA synthase (LdHMGS), HMG-CoA reductase (LdHMGR1 and...
Five insulin-like peptide LdILP genes were identified in Leptinotarsa decemlineata. All of them contained three exons and two introns, with three genes tandemly arrayed and well separated from the other two. Phylogenetic analysis revealed that the three LdILPs from three tandemly-arrayed genes grouped with TcILP1, whereas the other two resembled with TcILP2 and TcILP4 from Tribolium castaneum. Thus,...
Galectins constitute a group of lectins with binding specificity for β-galactoside sugars. Galectin-1 is a prototype galectin and the multifunctionality of mammalian galectin-1s is well-known, but only a few of fish galectin-1s have been identified. In this study, we obtained the full-length cDNA and genomic sequence of the galectin-1 gene (designated as Pdlgals1) from large scale loach (Paramisgurnus...
Jasmonates (JAs) act as conserved elicitors of plant secondary metabolism. JAs perception triggers extensive transcriptional reprogramming leading to activation of the entire metabolic pathways. The family of basic helix-loop-helix (bHLH) transcription factors (TFs) has essential roles in JA signaling; however, little is known about their roles in regulation of secondary metabolites in Isatis indigotica...
Serpins are a family of serine protease inhibitors that regulate physiological functions and are found widely in animals, plants and microorganisms. However, there are few reports on the role of serpins in the Chinese mitten crab, Eriocheir sinensis. We cloned two serpin genes from E. sinensis, named Esserpin-2 and Esserpin-3. Quantitative and semi-quantitative real-time PCR results showed that Esserpin-3...
In insect, juvenile hormone (JH) titers are tightly regulated in different development stages through synthesis and degradation pathways. During JH degradation, JH epoxide hydrolase (JHEH) converts JH to JH diol, and hydrolyses JH acid to JH acid diol. In this study, two full length LdJHEH cDNAs were cloned from Leptinotarsa decemlineata, and were provisionally designated LdJHEH1 and LdJHEH2. Both...
P38 mitogen-activated protein kinases (MAPKs) comprise a family of serine/threonine protein kinases that play important roles in cellular responses to inflammatory cytokines and environmental stresses. These kinases are involved in controlling cell division, differentiation and death in mammalian testes and therefore are critical to spermatogenesis. To explore their functions in male reproduction...
Juvenile hormone III (JH III) plays primary roles in regulation of metamorphosis, reproduction and diapause in Leptinotarsa decemlineata, a notorious defoliator of potato. The neurosecretory cell-borne substance(s) negatively affects the final two steps in JH biosynthesis, catalyzed respectively by an epoxidase CYP15A1 and a juvenile hormone acid methyltransferase (JHAMT). In a few insect species...
Postembryonic development of insects is highly dependent on ecdysteroid hormones ecdysone (E) and 20-hydroxyecdysone (20E). A cytochrome P450 monooxygenase CYP306A1, the product of the Halloween gene phantom (phm), is involved in the ecdysteroidogenesis in representative insects in Diptera, Lepidoptera and Orthoptera. In the present paper, Sfphm was cloned from a hemipteran insect species, the white-backed...
The Cullin-RING finger ligases (CRLs) are involved in the ubiquitin-mediated degradation of cell cycle regulators and play an important role in gametogenesis. Cullin 4 (CUL4) is a conserved core component of a new class of ubiquitin E3 ligase, and participates in the proteolysis of several regulatory proteins through the ubiquitin–proteasome pathway. The mammals encode two paralogs of CUL4, CUL4A...
Ecdysteroid hormone 20-hydroxyecdysone (20E) plays fundamental roles in insect development and reproduction, whereas the primary role of ecdysone (E) is the precursor for 20E. A cytochrome P450 monooxygenase (CYP), encoded by a Halloween gene Shade (Shd, cyp314a1), catalyzes the conversion of E into 20E in representative insect species in Diptera, Lepidoptera and Orthoptera. We describe here the cloning...
Published data on the rs2910164 in microRNA-146a (miR-146a) are shown to be associated with increased or decreased autoimmune diseases risk. To derive a more precise estimation of the relationship, we performed a meta-analysis to systematically summarize the possible. A meta-analysis including 11 studies with 3042 controls and 2197 cases was performed for genotypes CC (recessive effect), CC+CG (dominant...
p53R2 is a newly identified small subunit of ribonucleotide reductase and plays a pivotal role in the supply of dNTPs for genomic DNA repair and mitochondrial DNA synthesis, but little is known about its functions in zebrafish. Herein, we obtained the cDNA of zebrafish p53R2 that shares 72.8% and 72.5% amino acid identities with human p53R2 and zebrafish R2, respectively. Residues crucial for enzymatic...
