Reduced expression of microRNA-129 (miR-129) has been reported in several types of tumor cell lines as well as in primary tumor tissues. However, little is known about how miR-129 affects cell proliferation in gastric cancer. Here, we show that all miR-129 family members, miR-129-1-3p, miR-129-2-3p, and miR-129-5p, are down-regulated in gastric cancer cell lines compared with normal gastric epithelial...
Melanocortin 4 receptor (MC4R) has an important role in the regulation of energy homeostasis in both mammals and fish. In this study, MC4R was characterized in S. prenanti (Schizothorax prenanti) and designated as SpMC4R. SpMC4R cDNA is composed of 1004 nucleotides with a 978 nucleotide open reading frame encoding a protein of 326 amino acids. The SpMC4R contained predicted regions that were structural...
Polymorphisms of butyrylcholinesterase (BChE) have been reported to be associated to weight, BMI variance and hypertriglyceridemia in adults and adolescents. The aim of the present study was to investigate the association of −116A (SNP: G/A; rs1126680) and 1914G (SNP: A/G; rs3495) variants of BCHE gene with anthropometric and biochemical variables associated with obesity in population sample of 115...
The identification of clinically validated genetic variants contributing to complex disorders raise the possibility to investigate individuals' risk. In this line of research, the present work aimed to assess the genetic risk for cardiovascular disease (CVD) in Azoreans. Genotyping of 19 SNPs – 9 on 9p21, 5 on LDLR and 5 on USF1 – was performed by TaqMan assays on 170 healthy Azorean individuals....
We report a molecular cytogenetic characterization of 17p13.3 deletion syndrome by array comparative genomic hybridization (aCGH), fluorescence in situ hybridization (FISH) and quantitative polymerase chain reaction (qPCR) in a fetus with lissencephaly, corpus callosum dysgenesis, ventriculomegaly, microcephaly, intrauterine growth restriction (IUGR), polyhydramnios and single umbilical artery. aCGH...
Isoflavones play diverse roles in plant–microbe interactions and are potentially important for human nutrition and health. To study the regulation of isoflavonoid synthesis in soybean, the R2R3-MYB transcription factor GmMYB12B2 was isolated and characterized. Yeast expression experiments demonstrated that GmMYB12B2 showed transcriptional activity. GmMYB12B2 was localized in the nucleus when it was...
The exact pathogenesis of Parkinson's disease (PD) is still unknown and proper mechanisms that correspond to the disease remain unidentified. It is understood that PD is age-related; as age increases, the chance of onset responds accordingly. Although there are no current means of curing PD, the understanding of reactive oxygen species (ROS) provides significant insight to possible treatments. Complex...
In this study, we investigated the gene sequence and characteristic of kifc1 in Sepiella maindroni through PCR and RACE technology. Our research aimed particularly at the spatio-temporal expression pattern of kifc1 in the developmental testis through in situ hybridization. The particular role of kifc1 in the spermatogenesis of S. maindroni was our particular interest. Based on multiple protein sequence...
As a signaling molecule, bone morphogenetic protein 8B (BMP8B) plays an essential role in bone metabolism and is able to regulate thermogenesis and energy balance, which suggests that BMP8B gene may be a new candidate for growth traits. Here, to characterize the effects of BMP8B gene on growth traits, we first used three Chinese indigenous cattle breeds (n=845) to detect single nucleotide polymorphisms...
The complete mitochondrial genome of the sycamore lace bug, Corythucha ciliata, was sequenced in this study. It represents the first sequenced mitogenome of family Tingidae in Heteroptera. The mitogenome of C. ciliata is 15,257bp and contains 37 genes including 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes and a large non-coding region. Gene arrangement, nucleotide content, codon usage,...
Many epidemiological studies have indicated that interleukin-1α (IL-1α) −899 (+4845) C→T polymorphism increases the risk of chronic periodontitis (CP), whereas some studies have reported opposite results. Accordingly, the aim of this meta-analysis is to investigate the association of the IL-1α −899 (+4845) C→T polymorphism with CP. We searched the PubMed database up to May 1, 2013 and finally obtained...
Mucopolysaccharidosis IVA (MPS IVA) is an autosomal recessive lysosomal storage disorder caused by the deficiency of N-acetylgalactosamine-6-sulfate sulfatase (GALNS). Molecular mutational analysis was performed by PCR product sequencing for fourteen exons and exon–intron boundaries of GALNS gene in 21 patients from 19 unrelated families with severe MPS IVA in South China. We identified fifteen different...
Thalassemia is one of the most common hereditary disorders. This study aimed to investigate the prevalence of thalassemia and the mutation spectrum in Chongqing, the southern area of China.A total of 1057 children were recruited from Chongqing. Hematological parameters were examined and globin genes were genetically analyzed.The total frequency of thalassemia carriers was 7.76% in this group of children...
The hearing loss caused by GJB2 mutations is usually congenital in onset, moderate to profound in degree, and non-progressive. The objective of this study was to study genotype/phenotype correlations and to document 14 children with biallelic GJB2 mutations who passed newborn hearing screening (NHS). Genetic testing for GJB2 mutations by direct sequencing was performed on 924 individuals (810 families)...
We present prenatal diagnosis and array comparative genomic hybridization characterization of 3q26.31–q29 duplication and 9q34.3 microdeletion in a fetus with omphalocele, ventricular septal defect, increased nuchal translucency, abnormal first-trimester maternal screening and facial dysmorphism with distinct features of the 3q duplication syndrome and Kleefstra syndrome. The 26.61-Mb duplication...
MicroRNAs (miRNAs), a family of small nonprotein-coding RNAs, play a critical role in posttranscriptional gene regulation by acting as adaptors for the miRNA-induced silencing complex to inhibit gene expression by targeting mRNAs for translational repression and/or cleavage. miR-155-5p and miR-155-3p are processed from the B-cell Integration Cluster (BIC) gene (now designated, MIR155 host gene or...
•Association studies between GSTM1 and GSTT1 polymorphisms and DM risk are inconsistent.•The meta-analysis addresses whether GSTM1 and GSTT1 polymorphisms associated with DM.•There was significant heterogeneity between studies.•The null genotypes vs active genotypes of GSTM1 and GSTT1 increased the risk of DM.
Amanita exitialis is a lethal mushroom that was first discovered in Guangdong Province, China. The high content of amanitin in its basidiocarps makes it lethal to humans. To comprehensively characterize the A. exitialis transcriptome and analyze the Amanita toxins as well as their related gene family, transcriptome sequencing of A. exitialis was performed using Illumina HiSeq 2000 technology. A total...
Bone morphogenetic proteins (BMPs) are members of the TGF-β (transforming growth factor-beta) superfamily, of which BMP4 is the most important due to its crucial role in follicular growth and differentiation, cumulus expansion and ovulation. Reproduction is a crucial trait in goat breeding and based on the important role of BMP4 gene in reproduction it was considered as a possible candidate gene for...
