Primary hypertrophic osteoarthropathy (PHO) is a rare monogenetic disease characterized by digital clubbing, periostosis and pachydermia. Mutations in the 15-hydroxy-prostaglandin dehydrogenase (HPGD) gene and solute carrier organic anion transporter family member 2A1 (SLCO2A1) gene have been shown to be associated with PHO. Here, we described clinical characteristics in a Chinese patient with PHO,...
DNA methylation is a key epigenetic modification in mammals and has an essential and important role in muscle development. Insulin-like growth factor 2 (IGF2) is a fetal growth and differentiation factor that plays an important role in muscle growth and in myoblast proliferation and differentiation. The aim of this study was to evaluate the expression of IGF2 and the methylation pattern on the differentially...
In vitro neural differentiation of human embryonic stem cells (hESCs) is an advantageous system for studying early neural development. The process of early neural differentiation in hESCs begins by initiation of primitive neuroectoderm, which is manifested by rosette formation, with consecutive differentiation into neural progenitors and early glial-like cells. In this study, we examined the involvement...
The proliferation of retrotransposons within a genome can contribute to increased size and affect the function of eukaryotic genes. BEL/Pao-like long-terminal repeat (LTR) retrotransposons were annotated from the highly adaptable insect species Diabrotica virgifera virgifera, the Western corn rootworm, using survey sequences from bacterial artificial chromosome (BAC) inserts and contigs derived from...
Our recent genome-wide association study (GWAS) has identified 105 genome-wide significant SNPs for milk production traits. Of these, one SNP (rs109661298) for milk fat percentage is located within the first intron of the bovine EEF1D gene on BTA14, thus that the EEF1D gene was considered as a novel candidate in dairy cattle. Until now, however, its genomic organization remains undetermined yet and...
This work aimed to study a novel transgenic expression system of the CD/TK double suicide genes enhanced by the nuclear matrix attachment region (MAR) for gene therapy. The recombinant vector pMS-CD/TK containing the MAR–survivin promoter–CD/TK cassette was developed and transfected into human gastric cancer SGC-7901 cells. Expression of the CD/TK genes was detected by quantitative real-time PCR (qPCR)...
We report here the case of a term female newborn that developed severe respiratory distress soon after birth. She was found to be a compound heterozygote for both novel mutations in the ABCA3 gene.ABCA3 deficiency should be considered in mature babies who develop severe respiratory distress syndrome.
Metabolomics is one of the key approaches of systems biology that consists of studying biochemical networks having a set of metabolites, enzymes, reactions and their interactions. As biological networks are very complex in nature, proper techniques and models need to be chosen for their better understanding and interpretation. One of the useful strategies in this regard is using path mining strategies...
Metastasis is the most significant prognostic factor for laryngeal carcinoma which necessitates the identification of molecular alterations associated with metastasis. The identification of such molecular alterations will not only prove useful in treatment but also provide insight into mechanisms of cancer metastasis. The studies conducted so far have not specifically focused on metastasis or invasion...
Hypoxia represents a major physiological challenge for prawn culture, and the hepatopancreas plays an important role in these processes. Here, we applied high-throughput sequencing technology to detect the gene expression profile of the hepatopancreas in Macrobrachium nipponense in response to hypoxia for 3h and hypoxia for 24h. Gene expression profiling identified 1925 genes that were significantly...
Liriodendron chinense (Hemsl.) Sarg is an endangered species and occupies a pivotal position in phylogenetic studies of flowering plants, while its genomic resources are limited. In this study, we performed transcriptome sequencing for L. chinense petals and leaves using the Illumina paired-end sequencing technique. Approximately 17.02-Gb clean reads were obtained, and de novo assembly generated 87,841...
Monogenic congenital cataract is one of the most genetically heterogeneous ocular conditions with almost 30 different genes involved in its etiology. In adult patients, genotype–phenotype correlations are troubled by eye surgery during infancy and/or long-term ocular complications. Here, we describe the molecular diagnosis of GALK1 deficiency as the cause of autosomal recessive congenital cataract...
Congenital disorders of glycosylation (CDG) are a growing group of inherited metabolic disorders where enzymatic defects in the formation or processing of glycolipids and/or glycoproteins lead to variety of different diseases.The deficiency of GDP-Man:GlcNAc 2 -PP-dolichol mannosyltransferase, encoded by the human ortholog of ALG1 from yeast, is known as ALG1-CDG (CDG-Ik). The phenotypical,...
Heterozygous de novo mutations in SOX2 have been reported in approximately 10–20% of patients with unilateral or bilateral anophthalmia or microphthalmia. An additional phenotype of hypopituitarism, with anterior pituitary hypoplasia and hypogonadotropic hypogonadism, has been reported in patients carrying SOX2 alterations. We report a novel heterozygous mutation in the SOX2 gene in a male affected...
Telomeres are critical in maintaining genomic stability and integrity, and telomerase expression in spermatogonial stem cells is responsible for the maintenance of telomere length in the human male germline. Genetic variants in telomere-associated pathway genes might affect telomere length and chromosomal stability, and subsequently disease susceptibility. Thus, we hypothesize that single nucleotide...
Classical homocystinuria is the most commonly inherited disorder of sulfur metabolism, caused by the genetic alterations in human cystathionine beta-synthase (CBS) gene. In this study, we present comprehensive clinical findings and the genetic basis of homocystinuria in a cohort of Turkish patients. Excluding some CBS mutations, detailed genotype–phenotype correlation for different CBS mutations has...
T3801C is a common polymorphism in CYP1A1, showing differences in its biological functions. Case–control studies have been performed to elucidate the role of T3801C in cancer, although the results are conflicting and heterogeneous. Hence, we performed a meta-analysis to investigate the association between cancer susceptibility and T3801C (55,963 cases and 76,631 controls from 268 studies) polymorphism...
In this study, we found that Krüppel-like factor (KLF) 9 activate the progression of the early phase of adipocyte differentiation in mouse adipocytic 3T3-L1 cells. KLF9 mRNA was detected in preadipocytes; and its level increased after the initiation of adipocyte differentiation, reached its maximum at 1h, and gradually decreased thereafter. Functional suppression of KLF9 mRNA by its siRNAs repressed...
Cytotoxic T lymphocyte associated antigen4 (CTLA4) is a candidate susceptibility gene for the study of autoimmune diseases. The present study sought to explore the expression profile of the CTLA4 gene in autoimmune patients, such as rheumatoid arthritis (RA), systemic lupus erythematous (SLE) and Hashimoto's thyroiditis (HT), compared to healthy controls (HCs). A total of 88 (22 RA, 22 SLE 22 HT,...
The Piwi genes have an important role in stem cell development, gametogenesis and RNA interference in diverse organisms. So far, most of the studies have focused on the function of Piwis in vertebrates, but their function during spermiogenesis in invertebrates still remains largely unclear. In order to investigate the function of Piwis during spermiogenesis in the crab Portunus trituberculatus, we...
