Promoter activity and regulation of the Pou5f1 homolog from a teleost, Nile tilapia.
Abstract Mammalian POU5F1 (also known as OCT4) is an essential transcription factor that induces and controls stemness in the inner cell mass and embryonic stem (ES) cells. Its expression results from intricate regulatory networks involving its 5' upstream DNA elements and numerous transcription factors. Pou5f3, the ortholog of POU5F1, has been identified in non-mammalians including fish. However, little is known about the molecular mechanisms controlling its expression up to date. Here we report the promoter activity and regulation of Nile tilapia (Oreochromis niloticus) pou5f3 (Onpou5f3) in fish early-stage embr...

Evolution of vomeronasal receptor 1 (V1R) genes in the common marmoset (Callithrix jacchus).
Abstract Pheromones are crucial for eliciting innate responses and inducing social and sexual behaviors in mammals. The vomeronasal receptor 1 genes, V1Rs, encode members of a pheromone receptor family that are mainly expressed in the vomeronasal organ (VNO). The V1R family shows extraordinary variety in gene number among vertebrates owing to successive gene gains and losses during evolution. Such diversity is believed to reflect a degree of dependence on the VNO. We investigated V1R evolution in primate lineages closely related to humans because these VNOs show a trend toward degeneration. We performed extensive ...

Evaluating different DNA binding domains to modulate L1 ORF2p-driven site-specific retrotransposition events in human cells.
Abstract DNA binding domains (DBDs) have been used with great success to impart targeting capabilities to a variety of proteins creating highly useful genomic tools. We evaluated the ability of five types of DBDs and strategies (AAV Rep proteins, Cre, TAL effectors, zinc finger proteins, and Cas9/gRNA system) to target the L1 ORF2 protein to drive retrotransposition of Alu inserts to specific sequences in the human genome. First, we find that the L1 ORF2 protein tolerates the addition of protein domains both at the amino- and carboxy-terminus. Although in some instances retrotransposition efficiencies slightly dim...

EGFR and Ras regulate DDX59 during lung cancer development.
In this report, we found that both EGFR and Ras signaling can upregulate RNA helicase DDX59 in lung cancer cells. DDX59 can be induced through the mitogen activated protein kinase (MAPK) pathway after EGFR or Ras activation. Inhibitors for Ras/Raf/MAP pathway significantly decreased DDX59 expression at both protein and mRNA levels. Through immunohistochemistry, we found that DDX59 protein expression correlated with Ras and EGFR mutation status in human lung adenocarcinoma. Finally, through a xenograft nude mice model, we demonstrated that DDX59 is pivotal for EGFR mutated lung cancer cell growth in vivo. Our study identifi...

The tubby-like proteins kingdom in animals and plants.
Abstract Each gene of the tubby-like family is characterized by a signature of C-terminal tubby domain. The wide spread of this family in plants and animals implies they have an important function in various organisms. Even though the tubby-like genes are suggested to be putative transcription factors (TFs), how they execute the function as TFs is not yet clear. The biological functions of most animal tubby-like genes have been well studied, especially for vertebrate TUB, TULP1 and TULP3, but not with TULP2 and TULP4. Plants possess more tubby-like genes than animals, but their functions are still elusive except t...

Evaluation of PCSK9 levels and its genetic polymorphisms in women with polycystic ovary syndrome.
The objective of this study was to evaluate the PCSK9 polymorphisms rs505151 (c.2009A>G), rs562556 (c.1420A>G) and rs11206510 (T>C) and plasma PCSK9 levels in PCOS. A group of women with PCOS (n=97), and a group of healthy women (control, n=99) were selected. Biochemical parameters were determined by using Vitros system and polymorphisms were assessed by TaqMan SNP Genotyping Assays. Plasma PCSK9 levels or PCSK9 polymorphisms were not associated with PCOS. The genotype rs11206510TT was associated with higher levels of PCSK9 in both groups. The population investigated (PCOS+control groups) with the rs505151AA genot...

The rs2292239 polymorphism in ERBB3 gene is associated with risk for type 1 diabetes mellitus in a Brazilian population.
Abstract The Erb-b2 receptor tyrosine kinase 3 (ERBB3) belongs to a family of epidermal growth factor receptors of protein tyrosine kinases, and regulates cell survival, differentiation and proliferation in several cell types. Previous studies have suggested that ERBB3 contributes to T1DM pathogenesis by modulating antigen presenting cell function, autoimmunity and cytokine-induced beta-cell apoptosis. Accordingly, some genome-wide association studies identified ERBB3 gene as a susceptibility locus for T1DM, with the strongest association signal being observed for the rs2292239 single nucleotide polymorphism (SNP)...

Roles of DEK in the endometrium of mice in early pregnancy.
In this study, we investigated the expression of DEK in mouse uterus by immunohistochemistry (IHC), Western blotting. We explored its function during decidualization of uterine stromal cells by inhibiting the expression of DEK. In further study of mechanism, the cell proliferation, apoptosis and DNA damage were detected after inhibiting DEK during decidualization of stromal cells. The results suggest that DEK participates in decidualization of stromal cells through mediating cell proliferation, apoptosis and DNA repair.

The pathogenic gene screening in a Chinese familial dilated cardiomyopathy pedigree from Hubei.
In this study, we report a Chinese family with two members affected by TTN. Blood samples were collected from all family members. Genomic DNA was isolated from blood, and all coding exons and adjacent intronic sequences of the TTN gene were examined for mutation analysis using polymerase chain reaction (PCR)-based sequencing. The proband (III3) and his sister (III2) carry a TTN c.100126A>G (p.Thr33376Ala) missense mutation. The proband currently exhibits decreased cardiac function accompanied by malignant arrhythmia, and his sister has no obvious clinical symptoms and no abnormal ultrasound findings. The study found tha...

Eukaryotic and prokaryotic promoter databases as valuable tools in exploring the regulation of gene transcription: A comprehensive overview.
Abstract The complete exploration of the regulation of gene expression remains one of the top-priority goals for researchers. As the regulation is mainly controlled at the level of transcription by promoters, study on promoters and findings are of great importance. This review summarizes forty selected databases that centralize experimental and theoretical knowledge regarding the organization of promoters, interacting transcription factors (TFs) and microRNAs (miRNAs) in many eukaryotic and prokaryotic species. The presented databases offer researchers valuable support in elucidating the regulation of gene transcr...

Protein secondary structure prediction based on the fuzzy support vector machine with the hyperplane optimization.
Abstract The prediction of the protein secondary structure is a crucial point in bioinformatics and related fields. In the last years, machine learning methods have become a valuable tool, achieving satisfactory results. However, the prediction accuracy needs to be further ameliorated. This paper proposes a new method based on an improved fuzzy support vector machine (FSVM) for the prediction of the secondary structure of proteins. Unlike traditional methods to set the membership function, it firstly constructs an approximate optimal separating hyperplane by iterating the class centers in the feature space. Then s...
