Our previous study using comparative genome analysis revealed a significant gene copy number gain of Dissostichus mawsoni selenoprotein P (Dm-SEPP) during the evolutionary radiation of Antarctic notothenioids, suggesting that Dm-SEPP contribute to this process, but the detailed structure and function of this gene product remain unclear. In the present study, the Dm-SEPP cDNA was cloned and characterized...
Autophagy is an evolutionary conserved intracellular degradation/recycling system that is essential for cellular homeostasis. Dysregulation of this process leads to a number of disorders, including pulmonary fibrosis. However, the genetic association between singe nucleotide polymorphisms of autophagy related genes (ATGs) and the risk of coal workers' pneumoconiosis has not been reported yet. Total...
The proliferation and differentiation of skeletal muscle satellite cells is regulated by multiple regulatory factors including non-coding RNAs. It has been reported that miR-133b regulates myogenesis. In this study, we detected a novel lncRNA, lnc133b, which is completely complemented by mature miR-133b, indicating that lnc133b may regulate the expression of miR-133b by “sponge” miR-133b. A luciferase...
Acquired resistance to imatinib is frequently associated with poor clinical outcome of chronic myeloid leukemia (CML) patient. To date, evidence indicates that protein glycosylation and its upstream regulators might be implicated in tumorigenesis and chemoresistance occurrence. In current study we initially explored N-glycan profiles on the surface of CML cell lines and bone marrow mononuclear cells...
Aberrant expression of long noncoding RNA (lncRNA) HULC is associated with various human cancers. However, the role of HULC in chronic myeloid leukemia (CML) is unknown. In this study, we found that HULC was remarkably overexpressed in both leukemia cell lines and primary hematopoietic cells derived from CML patients. The increase in HULC expression was positively correlated with clinical stages in...
As the rate-limiting enzyme of the mitochondrial respiratory chain, cytochrome c oxidase (COX) plays a crucial role in biological metabolism. “Living fossil” giant panda (Ailuropoda melanoleuca) is well-known for its special bamboo diet. In an effort to explore functional variation of COX1 in the energy metabolism behind giant panda's low-energy bamboo diet, we looked at genetic variation of COX1...
The chemical and biological compositions of deep-sea sediments are interesting because of the underexplored diversity when it comes to bioprospecting. The special geographical location and climates make Arctic Ocean a unique ocean area containing an abundance of microbial resources.A metagenomic library was constructed based on the deep-sea sediments of Arctic Ocean. Part of insertion fragments of...
Human α-lactalbumin (HLA) has very high nutritional value and important physiological functions during the neonatal period. The peptides derived from HLA provide diverse health benefits including antimicrobial, antiviral, immune-modulating, and antihypertensive effects. Thus, it is worth investigating the effects on offspring development of increasing HLA in milk. In this study, we found that recombinant...
Mammalian testis development and spermatogenesis play critical roles in male fertility. However, little genomic information is available for porcine sexually mature and immature testis. Presently, we detected approximately 76% of previously annotated genes that were expressed in the porcine testes by RNA sequencing. Taking an FDR of 0.001 and a |log2Ratio| of 1 as cutoffs, 10,095 genes were significantly...
In insects, pigment patterns are formed by melanin, ommochromes, and pteridines. Here, the effects of pteridine synthesis on melanin formation were studied using 4th instar larvae of a wild-type silkworm strain, dazao (Bombyx mori), with normal color and markings. Results from injected larvae and in vitro integument culture indicated that decreased activity of guanosine triphosphate cyclohydrolase...
Stress-inducible protein 1 (Stip1) is one of the well-studied co-chaperones, although limited researches have been conducted in testis and epididymis. Here we found that Stip1 was ubiquitously expressed in various human tissues, including the testis and epididymis. In human testis and epididymis, Stip1 was localized in the cytoplasm of diverse cell types. Stip1 showed a developmentally-regulated manner...
MECP2 duplication results in a well-recognised syndrome in 100% of affected male children; this syndrome is characterised by severe neurodevelopmental disabilities and recurrent infections. However, no sonographic findings have been reported for affected foetuses, and prenatal molecular diagnosis has not been possible for this disease due to lack of prenatal clinical presentation. In this study, we...
Colorectal cancer (CRC) is one of the leading causes of death around the world. Its genetic mechanism was intensively investigated in the past decades with findings of a number of canonical oncogenes and tumor-suppressor genes such as APC, KRAS, and TP53. Recent genome-wide association and sequencing studies have identified a series of promising oncogenes including IDH1, IDH2, DNMT3A, and MYD88 in...
Mitochondrial genome (mitogenome) can provide information for genomic structure as well as for phylogenetic analysis and evolutionary biology. In this study, we present the complete mitogenome of the atlas moth, Attacus atlas (Lepidoptera: Saturniidae), a well-known silk-producing and ornamental insect with the largest wing surface area of all moths. The mitogenome of A. atlas is a circular molecule...
The aim of the study was to evaluate the contribution of BMPER promoter SNPs to the gene expression and intramuscular fat content in longissimus dorsi muscle. Firstly the promoter region of BMPER was comparatively scanned by direct sequencing with pool DNA of two groups (n=15 for each group) with high (H) or low (L) IMF content. Two SNPs, c.−1423A>G and c.−1344A>C, were found to have reverse...
Apolipoprotein B mRNA-editing enzyme catalytic subunit 2 (APOBEC2) plays an important role in regulating and maintaining muscle development in mammals. In this study, we evaluated APOBEC2 mRNA abundance and protein expression and the results indicated that APOBEC2 mRNA was most abundant in skeletal and cardiac muscle, with relatively low expression in the gonads, gizzard and subcutaneous fat tissues...
Retinol-binding protein 4 (RBP4) is the only circulatory transport protein for vitamin A. Based on the essential role of vitamin A in chicken reproduction, we measured RBP4 mRNA abundance in Erlang mountainous chickens. We also identified and analyzed the gene polymorphism and its effect on reproduction traits among 349 chickens. The expression of RBP4 mRNA showed specific developmental changes and...
Salt, saline–alkali and drought stresses are major environmental constraints for the production and yield of soybean worldwide. To identify genes responsible for stress tolerance, the transcriptional profiles of genes in leaves and roots of seedlings (two-leaf stage) of the soybean inbred line HJ-1 were examined after 48h under various stress conditions; salt (120mM NaCl), saline–alkali (70mM NaCl...
Many epidemiological studies have investigated the associations between polymorphisms of interleukin-1 (IL1) and interleukin-6 (IL6) genes and risk of ischemic stroke (IS), but no conclusions are available because of conflicting results. The aim of this study was to assess the relationships by meta-analysis. The databases of Pubmed, Embase and Wangfang, updated to August 1st, 2011, were retrieved...
The epididymis plays a crucial role in regulating the development of sperm motility and fertilizing capacity. Small non-coding RNAs (sncRNAs), especially microRNAs (miRNAs), can participate in the regulation of various physiological pathways. However, their abundance and whether they are involved in the regulation of gene expression in the human epididymis are unknown. By adopting the Solexa deep...
