Krüppel-like factor 3 (KLF3), a member of the Krüppel-like factor (KLF) family, plays an important role in adipogenesis and lipid metabolism. The aim of this study was to investigate whether KLF3 could be used as a candidate gene in the breeding of cattle. The expression pattern of bovine KLF3 gene revealed that it was highly expressed in abdominal fat and perirenal fat. Using DNA sequencing, three...
Fatty acid synthase (FASN) is an enzyme involved with fat deposition and fatty acid composition in cattle. This study was conducted to detect single nucleotide polymorphisms (SNPs) of the FASN gene and explore their relationships with ultrasound carcass traits in order to assess the potential use of the FASN gene for the breeding selection of Qinchuan cattle for desirable carcass traits. The frequencies...
Lysiphlebia japonica (Ashmead) is a predominant parasitoid of cotton-melon aphids in the fields of northern China with a proven ability to effectively control cotton aphid populations in early summer. For accurate normalization of gene expression in L. japonica using quantitative reverse transcriptase-polymerase chain reaction (RT-qPCR), reference genes with stable gene expression patterns are essential...
Cyclin-dependent kinases (CDKs) are important regulators of the cell cycle; previous studies have shown that misregulation of CDK4 (cyclin-dependent kinase 4) activity can lead to cancer. The present study investigated the anti-tumor effects of a highly selective CDK4 inhibitor fascaplysin in ovarian carcinoma cell lines.In our study, cell proliferation, cell cycle, cell apoptosis, cell invasion,...
Ovarian carcinoma is one of the highest incidence of tumors in women, and the generation, development and prognosis of epithelial ovarian carcinoma (EOC) remains an open field of study. The role of long non-coding RNAs (lncRNAs) in epithelial ovarian carcinoma is an emerging area of research.LncRNA PCA3 expression was determined in EOC and normal ovarian tissues by RT-PCR. Phenotypes indicative of...
MicroRNA-372 has been shown to be associated with multiple tumors' development and progression, by regulating the expression of proteins involved in cell cycle and apoptosis. However, the specific mechanism and function of miR-372 in ovarian carcinoma are not clear. Our study explored the role of miR-372 in ovarian carcinoma cell cycle and proliferation.MiR-372 expression was quantified in normal...
TDH, encoded by tdh gene, is a major virulent determinant of V. parahaemolyticus that controls various biological activities, such as hemolytic activity, cytotoxicity, and enterotoxicity. The hemolytic activity on Wagatsuma agar ascribed to TDH is called Kanagawa phenomenon (KP). All KP positive strains contain tdh1 and tdh2 genes, but tdh2 is predominantly responsible for KP. CalR is a regulatory...
Chinese hamster ovary (CHO) cells offer many advantages for recombinant gene expression, including proper folding and post-translational modification of the recombinant protein. However, due to positional effects resulting from the neighboring chromatin, transgenes are often expressed at low levels in these cells. While previous studies demonstrated that matrix attachment regions (MARs) can be utilized...
Trehalose-6-phosphate synthase (TPS) plays an important role in metabolic regulation and stress responses in a variety of organisms. However information about cotton TPS is poor. Here a cotton TPS gene GhTPS11 was isolated and characterized. Expression analysis revealed that GhTPS11 was induced in 20-day old cotton seedlings by heat drought and high salt stresses as well as GA and ABA. Moreover GhTPS11...
The miR2118 is highly conserved in leguminous plants. Its function is to regulate the expression of genes encoding the TIR-NBS-LRR resistance protein. In this study, cin-miR2118 from Caragana intermedia was functionally characterized, especially with regard to its role in drought stress resistance. Two target genes of cin-miR2118 were predicted and cloned, the occurrence of miR2118 target sequence...
The enzymatic activity of CYP2C9 results in broad inter-individual variability in response to certain pharmacotherapies. The present study aimed to screen Tibetan volunteers for CYP2C9 genetic polymorphisms. Previous research has focused on Han Chinese patients, while little is known about the genetic variation of CYP2C9 in Tibetan populations.We used DNA sequencing to investigate the promoter, exons...
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...
An ideal gene therapy vector should enable persistent transgene expression without limitations in safety and reproducibility. Recent researches' insight into the ability of chromosomal matrix attachment regions (MARs) to mediate episomal maintenance of genetic elements allowed the development of a circular episomal vector. Although a MAR-mediated engineered vector has been developed, little is known...
Ammonium is the main inorganic nitrogen source in paddy soil. Rice (Oryza sativa), an ammonium-preferring and -tolerant grain crop, is a valuable resource for researching ammonium-uptake mechanism and understanding the molecular networks that the plant copes with ammonium variation. To generate a broad survey of early responses affected by varied ammonium supplies in rice, RNA samples were prepared...
Systemic lupus erythematosus (SLE) is one of the common autoimmune diseases, with complex genetic components. Interleukin-21 (IL-21) is the most recently discovered member of the type-I cytokine family, which has a variety of effects on the immune system, including B cell activation, plasma cell differentiation, and immunoglobulin production. Previous studies have identified that IL-21 was associated...
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...
The full-length cDNA sequence (2613bp) of the trehalose-6-phosphate synthase (TPS) gene of eelgrass Zostera marina (ZmTPS) was identified and cloned. Z. marina is a kind of seed-plant growing in sea water during its whole life history. The open reading frame (ORF) region of ZmTPS gene encodes a protein of 870 amino acid residues and a stop codon. The corresponding genomic DNA sequence is 3770bp in...
A full-length cDNA and genomic sequences of a translationally controlled tumor protein (TCTP) gene were isolated from Japanese larch (Larix leptolepis) and designated LaTCTP. The length of the cDNA was 1043bp and contained a 504bp open reading frame that encodes a predicted protein of 167 amino acids, characterized by two signature sequences of the TCTP protein family. Analysis of the LaTCTP gene...
To estimate the phylogeny and molecular evolution of a single-copy gene encoding plastid acetyl-CoA carboxylase (Acc1) within the StH genome species, two Acc1 homoeologous sequences were isolated from nearly all the sampled StH genome species and were analyzed with those from 35 diploid taxa representing 19 basic genomes in Triticeae. Sequence diversity patterns and genealogical analysis suggested...
Due to the difficulties in deep sequencing, high-throughput sequencing of ancient DNA has been limited to exceptionally well-preserved ancient materials. The primary factor is microbial attack popularly observed in the buried materials, and it causes drastic increase in relative ratio of microbial DNA in the extracted DNA. We present a unified strategy in which emulsion PCR is coupled with target...
