Hepatocyte nuclear factor-4α (HNF-4α), a member of the hepatocyte nuclear factor family, plays an important role in regulating the expression of genes involved in the development, differentiation and normal function of liver and pancreatic β cells, as well as the maintenance of glucose homeostasis. Tetra-primer amplification refractory mutation system PCR (T-ARMS-PCR) is a new method offering fast...
We investigated whether Helicobacter pylori (H. pylori) CagA contributes to the DNA copy change and mRNA transcript expression of the HER-2 gene and, consequently, affects HER-2 protein expression to evaluate the significance of CagA and HER-2 amplification in gastric cancer. We used the AGS and MKN1 gastric cancer and HFE-145 immortalized non-neoplastic gastric mucosa cell lines. We also confirmed...
Copy number variation has recently been recognized as an important type of genetic variation that modifies human phenotypes. Copy number variants (CNVs) are being increasingly associated with various human phenotypes and diseases. However, the lack of an appropriate method that allows fast, inexpensive and, most importantly, accurate CNVs genotyping significantly hampers CNV analysis. This limitation...
β-Catenin is an evolutionarily conserved molecule that functions as a crucial effector in both cell-to-cell adhesion and Wnt signaling. To gain a better understanding of its role in the development of hair follicles, we cloned the cDNA sequence of the β-catenin gene from the skin of Aohan fine-wool sheep and performed a variety of bioinformatics analyses. We obtained the full-length sequence, which...
Galectin-3 is a multifunctional β-galactoside-binding protein which has been shown to play a role in carcinogenesis. However, the involvement of galectin-3 in osteosarcoma remains unclear. In this study, we aimed to examine the serum level of galectin-3 in osteosarcoma patients and healthy controls, and the protein expression of galectin-3 in osteosarcoma tissues and their adjacent non-malignant tissues...
Left ventricular dysfunction (LVD) is a complex, multifactorial condition, caused by mechanical, neurohormonal, and genetic factors. We have previously observed association of renin–angiotensin–aldosterone system (RAAS), matrix metalloproteinases (MMPs) and inflammatory pathway genes with LVD. Therefore the present study was undertaken to identify the combination of genetic variants and their possible...
The clinical interpretation of variants in mismatch repair (MMR) genes associated with Lynch syndrome can be confusing when the functional nature of the variant is not clearly defined. We report an extreme case where a polymorphism in the MSH2 gene which had a low minor allele frequency, was misclassified as a mutation based on low evidential methods in the database and previous publications. We expanded...
The genomic as well as structural relationship of phycobiliproteins (PBPs) in different cyanobacterial species are determined by nucleotides as well as amino acid composition. The genomic GC constituents influence the amino acid variability and codon usage of particular subunit of PBPs. We have analyzed 11 cyanobacterial species to explore the variation of amino acids and causal relationship between...
Growth differentiation factor 9 (Gdf9) and bone morphogenetic protein 15 (Bmp15) are members of transforming growth factor β (TGFβ) superfamily that plays important roles in regulating ovarian functions. We cloned the cDNAs of gdf9 and bmp15 in rare minnow Gobiocypris rarus. The full length cDNAs of gdf9 and bmp15 were 1999 and 1721bp, encoding 431 and 384 amino acids respectively. They both contained...
In this study, we evaluated a novel microsomal glutathione S-transferase3 (MGST3) gene from the dinoflagellate Prorocentrum minimum, and examined its expression pattern in response to copper-and nickel-induced stresses. The full length of PmMGST3 was 732bp, ranging from the dinoflagellate splice leader (DinoSL) sequence to the poly (A) tail, covering a 441-bp ORF, 97-bp 5′UTR, and 194-bp 3′UTR. The...
Improvement of host plant resistance is one of the best methods to protect the yield from biotic stresses. Incorporation of major resistance genes or their variants into elite rice varieties will enhance the host plant resistance and its durability. Allele mining is a preferred choice to discover the novel allelic variants of major genes from wide range of germplasm. ‘True’ allele mining includes...
Where possible, developments enabling the establishment of cell lines with predictable, long-term stable expression capacity are based on single-copy integrations at safe genomic loci with predictable properties. Robust performance could be assigned to lentiviral transduction systems anchoring single LV-units at sites with adequate transcription potential. In the case of gene therapeutic vectors it...
In order to gain insights into the mechanism of high nitrogen use efficiency (NUE) of finger millet (FM) the role of Dof2 transcription factor (TF), which is a repressor of genes involved in C/N metabolism was investigated. The partial cDNA fragment of EcDof2 (912-bp; GenBank acc. no. KF261117) was isolated and characterized from finger millet (FM) that showed 63% and 58% homology with Dof2 of Zea...
The objectives of this study were to evaluate the in vitro anti-tumor (human thyroid cancer cell lines) potential of curcumin and to elucidate its molecular mechanisms. Here, we investigated the effects of curcumin on the cell viability, apoptosis, migration and invasion of human thyroid cancer cell lines FTC133. We also investigated the effects of curcumin on PI3K, p-Akt, MMP1/7, and COX-2 protein...
In this study, we performed cloning and expression analysis of six putative sucrose transporter genes, designated TcSUT1, TcSUT2, TcSUT3, TcSUT4, TcSUT5 and TcSUT6, from the cacao genotype ‘TAS-R8’. The combination of cDNA and genomic DNA sequences revealed that the cacao SUT genes contained exon numbers ranging from 1 to 14. The average molecular mass of all six deduced proteins was approximately...
Autosomal dominant polycystic kidney disease is the most common human monogenic disorder and is caused by mutations in the PKD1 or PKD2 genes. Most patients with the disease present mutations in PKD1, and a considerable number of these alterations are single base substitutions within the coding sequence that are usually predicted to lead to missense or synonymous mutations. There is growing evidence...
This paper reports that Slow-tonic S2 tropomyosin (Sst) and Slow tropomyosin isoform (Sti) was highly expressed in androgenic gland transcriptome of Macrobrachium nipponense, which may play crucial roles in sexual differentiation to maleness. In this study, two Sst and Sti gene homologues designated as Mnsst and Mnsti were cloned and characterized from a freshwater prawn M. nipponense. The full-length...
Hoyeraal–Hreidarsson syndrome is a severe multisystem disorder that is characterized by bone-marrow failure, intrauterine growth retardation, microcephaly, immunodeficiency, and cerebellar atrophy. This rare disease shares clinical features with dyskeratosis congenita and, together, they are recognized as a group of disorders caused by telomere dysfunction. As the genetic background of dyskeratosis...
MiRNAs are a novel group of non-coding small RNAs that negatively regulate gene expression. Many miRNAs have been identified and investigated extensively in plant species with sequenced genomes. However, few miRNAs have been identified in foxtail millet (Setaria italica), which is an ancient cereal crop of great importance for dry land agriculture. In this study, 271 foxtail millet miRNAs belonging...
