MicroRNAs (miRNAs) are a class of ~22-nt non-coding small RNA that play an important role in various metabolic processes, mainly through suppressing the expression of protein coding genes at post-transcriptional level. Drip loss (DL) is one of the most important meat quality traits affecting the end product yield and quality of pork. To date, the underlying regulatory factors involved in DL trait...
Genomic rearrangements, such as intragenic deletions and duplications, are the most prevalent types of mutation in the DMD gene, and DMD mutations underlie Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD). Using multiplex ligation dependent probe amplification (MLPA) and DMD gene-targeted sequencing, we performed a molecular characterization of two cases of complex noncontiguous...
To investigate the molecular mechanism underlying differential lipid deposition between intramuscular (IM) and subcutaneous (SC) fat tissues of pigs, peroxisome proliferator-activated receptor gamma (PPARG) expression levels were compared in these two types of adipose tissues. The results showed that both mRNA and protein levels of PPARG were significantly higher in SC fat than in IM fat. Correspondingly,...
Wolfiporia cocos Ryvarden et Gilbertson, a well-known medicinal fungus in the Basidiomycetes, is widely distributed in East Asia. Its dried sclerotium, which is known as Fuling in China, has been used as a traditional crude drug in Chinese traditional medicine for thousand years. However, little is known about how the sclerotium is developed at the genetic level. In this study, the de novo sequencing...
Doublesex and Mab3 related transcription factor (DMRT), characterized by a conserved DM domain, function as sex-related transcription factors and also play critical roles in ontogenesis. In this study, 4 Dmrt genes in the blunt snout bream, Megalobrama amblycephala, were identified, characterized and their mRNA expression in different adult organs, during embryogenesis and gonadal development in larvae...
Mammary glands are organs for milk production in female mammals. Growth hormone (GH) is known to affect the growth and development of the mammary gland, as well as to increase milk production in dairy goats. This study performed a comprehensive expression profiling of genes expressed in the mammary gland of early involution GH transgenic (n=4) and non-transgenic goats (n=4) by RNA sequencing. RNA...
We performed genome-wide identifications and comparative genomic analyses of the predicted aspartic proteases (APs) from eight parasitic flatworms, focusing on their evolution, potentials as drug targets and expression patterns. The results revealed that: i) More members of family A01 were identified from the schistosomes than from the cestodes; some evidence implied gene loss events along the class...
Excess accumulation of cholesterol in plasma may result in coronary artery disease. Numerous studies have demonstrated that ATP-binding cassette protein A1 (ABCA1) mediates the efflux of cholesterol and phospholipids to apolipoproteins, a process necessary for plasma high density lipoprotein (HDL) formation. Higher plasma levels of HDL are associated with lower risk for cardiovascular disease. Studies...
Growing evidence suggests that defective expression or dysfunction of LAIR-1, a novel immunoinhibitory receptor for collagen, is closely associated with some autoimmune diseases, cancers, as well as viral infections. We analyzed the variation of LAIR-1 genetic pathways in murine versus human internal organs, including the lung and brain. The results showed that, under physiological conditions, LAIR-1...
As a key component of the Toll signaling pathway, Tube plays central roles in many biological activities, such as survival, development and innate immunity. Tube has been found in shrimps, but has not yet been reported in the crustacean, Eriocheir sinensis. In this study, we cloned the full-length cDNA of the adaptor Tube for the first time from E. sinensis and designated the gene as EsTube. The full-length...
We present the complete mitogenome of a stonefly, Cryptoperla stilifera Sivec (Plecoptera; Peltoperlidae). The mitogenome was a circular molecule consisting of 15,633 nucleotides, 37 genes and a A+T-rich region. C. stilifera mitogenome was similar to Pteronarcys princeps mitogenome (Plecoptera; Pteronarcyidae). All transfer RNA genes (tRNAs) had typical cloverleaf secondary structures except for trnSer...
The complete 15,223-bp mitochondrial genome (mitogenome) of Tryporyza incertulas (Walker) (Lepidoptera: Pyraloidea: Crambidae) was determined, characterized and compared with seven other species of superfamily Pyraloidea. The order of 37 genes was typical of insect mitochondrial DNA sequences described to date. Compared with other moths of Pyraloidea, the A+T biased (77.0%) of T. incertulas was the...
Polymorphisms in the endothelial nitric oxide synthase (eNOS) gene may influence the risk of ischemic stroke (IS), but the results are still debatable. A meta-analysis was performed to investigate the association between the eNOS gene polymorphisms in IS risk. Case–control studies on the association between the G894T, T-786C, and 4b/a polymorphisms and IS were searched up to July 2012, and the genotype...
Mouse ovarian surface epithelium (OSE) is a single layer of cubodial epithelial cells that covers the ovary surface and is involved in regulating the secretion and transport of 17β-hydroxysteroid dehydrogenase. Recently, OSE cells have attracted particular interest as a major source of ovarian cancer. Death-associated protein DAXX along with PML (promyelocytic leukemia protein) nuclear bodies (PML-NBs)...
CXCR4-tropic (X4) variants are associated with faster disease progression than CCR5-tropic variants in HIV infection. We previously reported inhibition of CCR5 expression on U937 cells could protect the cells from HIV-1 infection. Here, we established recombinant adenoviruses containing anti-sense CXCR4 cDNA, to investigate its role in the protection of HIV entering into target cells. A fragment of...
Cdc2 kinase is a catalytic subunit of the maturation-promoting factor (MPF), a central factor for inducing the meiotic maturation of oocytes. MPF has been studied in a wide variety of animal species; however, its expression in crustaceans is poorly characterized. In this study, a complete cDNA sequence of Cdc2 kinase was cloned from the red claw crayfish, Cherax quadricarinatus, and its spatiotemporal...
The complete mitochondrial genome sequence of Liriomyza sativae Blanchard (15,551bp) was determined and analyzed in this study. The circular genome contained 37 genes including 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and an A+T-rich region. The initiation codons of COI and ND1 were ‘ATCA’ and ‘GTG’, respectively. ND2 gene used the truncated termination codon ‘T’. All the tRNA genes had...
