Fast ω-gliadins were minor components of wheat storage proteins but a major antigen triggering allergy to wheat. Sixty-six novel full-length fast ω-gliadin genes with unique characteristics were cloned and sequenced from wheat and its relative species using a PCR-based strategy. Their coding regions ranged from 177bp to 987bp in length and encoded 4.28kDa to 37.56kDa proteins. On the base of first...
Non-coding RNAs are emerging as regulatory RNAs that participate in the regulation of gene expression and play vital roles in various biological and pathological processes. Long non-coding (lncRNA) is a novel class of non-coding RNAs that regulates gene expression by binding to chromatin regulators and interfering RNAs to affect cellular response. Myocardial infarction associated transcript (MIAT)...
Pax6 functions as a pleiotropic regulator in eye development and neurogenesis. Its splice variant Pax6 5a has been cloned in many vertebrate species including human and mouse, but never in rat. This study focused on the cloning and characterization of the Pax6 5a orthologous splicing variant in rat. It was cloned from Sprague–Dawley rats 10days post coitum (E10) by RT-PCR and was sequenced for comparison...
Pearl oyster Pinctada fucata is widely cultured to produce seawater pearl in South China, and the quality of pearl is significantly affected by its shell color. Thus the Pearl Oyster Selective Breeding Program (POSBP) was carried out for the shell color and growth traits. The black (B), gold (G), red (R) and white (W) shell strains with fast growth trait were achieved after five successive generation...
CD4 + CD25 + regulatory T cell-mediated immunosuppression is one of the crucial mechanisms that tumor cells use to evade the immune system. The forkhead box P3 (FoxP3) gene regulates regulatory T-cell development and function and may modulate the susceptibility to non-small cell lung cancer (NSCLC). Because a single nucleotide polymorphism (SNP) within the FoxP3 gene (rs3761548 in...
The present study investigated the expression of the apoptosis-related genes fas-associated via death domain (FADD) and Bcl-2 in the endometrium during the window of implantation in polycystic ovary syndrome (PCOS) patients. The aim was to explore the role of cell apoptosis in endometrial receptivity during this period. The subjects were divided into experimental and control group. The experimental...
Phenotypic variation among individuals in a population can be due to DNA sequence variation in protein coding regions or in regulatory elements. Recently, many studies have indicated that mutations in regulatory elements may be the major cause of phenotypic evolution. However, the mechanisms for evolutionary changes in gene expression are still not well understood. Here, we studied the relative roles...
Toll-like receptor 4 (TLR4) is critical in the recognition of Gram-negative bacteria serving as a key immune system effector. Recently, a number of case-control studies were conducted to investigate the association between TLR4 gene polymorphism and cancer risk, especially Asp299Gly and Thr399Ile polymorphisms. However, published data were still conflicting. In this paper, we summarized 9463 cancer...
The issue that genetic polymorphism of matrix metalloproteinase (MMP) family is in association with coronary disease is controversial. So we did a meta-analysis to clarify it clearly. We made a literature search of PubMed, the Web of Science, and Cochrane Collaboration's database to identify eligible reports. The methodological quality of each included studies was assessed. We calculated the pooled...
To gain a better understanding of gene expression in early flowering trifoliate orange mutant (precocious trifoliate orange, Poncirus trifoliata L. Raf.), we performed suppression subtractive hybridization, which allowed identification of flowering-related genes in the mutant and the wild type in the juvenile phase. Using macroarray analysis, we identified 125 and 149 non-redundant expressed sequence...
Human activation protein-2 gamma (hAP-2γ) is a key developmental transcription factor. It has been implicated in mammary carcinogenesis through its regulation of HER-2/neu proto-oncogene and estrogen receptor gene The hAP-2γ gene is located on human chromosome 20q13.2. We cloned this gene, deduced its genomic structure, and mapped and analyzed its promoter. The hAP-2γ gene contains seven exons. Primer...
Interleukin-4 (IL-4) is a pleiotropic immunomodulatory cytokine secreted by T helper 2 cells. The IL-4 promoter contains multiple sites with DNA sequences homologous to the IL-2 NF-AT binding site. One of these sites—the P2 site—located between –173 and –150 was previously found to be flanked by two octamer-like motifs. NF-ATp/c and octamer proteins were suggested to bind to this region and to cooperatively...
The positive regulatory element-I (PRE-I) is a strong enhancer element essential for expression of the human interleukin-4 (IL-4)-encoding gene. In order to identify transcription factors binding to PRE-I, we screened a cDNA expression library from human Jurkat T-cells. A cDNA encoding the human CCAAT/enhancer binding protein-γ (hC/EBPγ) was cloned. The deduced amino acid (aa) sequence of hC/EBPγ...
