1. NOS3 gene intron 4 a/b polymorphism is associated with ESRD in autosomal dominant polycystic kidney disease patients
Resumo Introdução: Genes da óxido nítrico sintase endotelial (eNOS) têm sido implicados na hemodinâmica renal como potentes reguladores do tônus vascular e pressão arterial. Tem sido vinculado a uma redução nos níveis plasmáticos de óxido nítrico. Realizou-se recentemente vários estudos para investigar o papel de polimorfismos do gene NOS3 e

2. Possible association between a polymorphism of EPAS1 gene and persistent pulmonary hypertension of the newborn: a case-control study
Abstract Objective: To explore possible genes related to the development of persistent pulmonary hypertension of the newborn (PPHN). Methods: The authors identified 285 single nucleotide polymorphisms (SNPs) of 11 candidate genes (BMPR2, EPAS1, PDE3A, VEGFA, ENG, NOTCH3, SOD3, CPS1, ABCA3, ACVRL1, and SMAD9), using an Illumina Asian Screening Array-24 v1.0

3. Cushing disease due to a somatic USP8 mutation in a patient with evolving pituitary hormone deficiencies due to a germline GH1 splicing variant
SUMMARY We present the unique case of an adult Brazilian woman with severe short stature due to growth hormone deficiency with a heterozygous G to T substitution in the donor splice site of intron 3 of the growth hormone 1 (GH1) gene (c.291+1G>T). In this autosomal dominant form of growth hormone deficiency (type II), exon 3 skipping results in expression of

4. Identificação molecular, caracterização e análise de expressão de um gene inibidor de serina protease da lagarta Helicoverpa armigera (Lepidoptera: noctuidae) na cultura de algodão
Resumo Sabe-se que os inibidores de serina protease (serpinas), uma superfamília de inibidores de protease, estão envolvidos em vários processos fisiológicos, como desenvolvimento, metamorfose e imunidade inata. Neste estudo, um cDNA de serpina de comprimento total, denominado Haserpin1, foi isolado da lagarta Helicoverpa armigera na cultura de algodão.

5. Toward a phylogenetic reclassification of the subfamily Ambavioideae (Annonaceae): establishment of a new subfamily and a new tribe
ABSTRACT A molecular phylogeny of the subfamily Ambavioideae (Annonaceae) was reconstructed using up to eight plastid DNA regions (matK, ndhF, and rbcL exons; trnL intron; atpB-rbcL, psbA-trnH, trnL-trnF, and trnS-trnG intergenic spacers). The results indicate that the subfamily is not monophyletic, with the monotypic genus Meiocarpidium resolved as the seco

6. How history and geography may explain the distribution in the Comorian archipelago of a novel mutation in DNA repair-deficient xeroderma pigmentosum patients
Abstract Xeroderma pigmentosum (XP) is a rare, genetic, autosomal nucleotide excision repair-deficient disease characterized by sun-sensitivity and early appearance of skin and ocular tumors. Thirty-two black-skinned XP from Comoros, located in the Indian Ocean, were counted, rendering this area the highest world prevalence of XP. These patients exhibited a

7. Polymorphisms in MyoD1, MyoG, MyF5, MyF6, and MSTN genes in Santa Inês sheep
Resumo: O objetivo deste trabalho foi sequenciar os genes MyoD1, MyoG, MyF5, MyF6 e MSTN e identificar polimorfismos em ovinos Santa Inês (Ovis aries). No total, 192 cordeiros com 240 dias de idade foram avaliados, e estes genes foram sequenciados para comparação com a sequência-referência no genoma de Ovis aries. As frequências genotípicas e alélica

8. Systematic molecular analysis of hemophilia A patients from Colombia
Abstract Hemophilia A (HA) is an X-linked recessive disorder and the second most common coagulation disorder with an incidence of 1 in 5,000 live born males. Worldwide, there are 178,500 affected individuals, 60% with the severe form of the disease. Intron 22 and 1 inversions (Inv22 and Inv1) are the most frequent molecular alterations found in severe HA pat

9. Genome-wide characterization of the NRAMP gene family in Phaseolus vulgaris provides insights into functional implications during common bean development
Abstract Transporter proteins play an essential role in the uptake, trafficking and storage of metals in plant tissues. The Natural Resistance-Associated Macrophage Protein (NRAMP) family plays an essential role in divalent metal transport. We conducted bioinformatics approaches to identify seven NRAMP genes in the Phaseolus vulgaris genome, investigated the

10. Polimorfismo de nucleotídeo único do gene IRF6 rs2235375 está associado com à fenda palatina isolada não sindrômica, mas não com fenda labial com ou sem fenda palatina em população do sul da Índia
Resumo Introdução Fatores de transcrição constituem uma família de proteínas muito diversa envolvida na ativação ou repressão da transcrição de um gene, em um determinado momento. Vários estudos usando modelos animais demonstraram o papel dos genes do fator de transcrição no desenvolvimento craniofacial. Objetivo Nosso objetivo foi investigar

11. Molecular characterization of Moenkhausia (Pisces: Characiformes) populations with different lateral line developmental levels
ABSTRACT The genera Hemigrammus and Moenkhausia have been traditionally diagnosed mainly by the former having lateral line completely pored whereas the latter having a lateral line with a few pored scales. Those features have been used to diagnose species of both genera in the upper Paraná River floodplain. Specimens with the diagnostic features of Moenkhau

12. The Differential Expression and Snp Analysis of the Ovoinhibitor Gene in the Ovaries of Laying Duck Breeds (Anas Platyrhynchos)
ABSTRACT Ovoinhibitor (OIH) is the main proteinase inhibitor in the egg white. In the present study, real-time quantitative PCR and Western-Blot were used to analyze different expression pattern of OIH in ovaries as a candidate gene of reproductive traits in Jingjiang ducks (JJ ducks) and Shaoxing ducks (SX ducks) during three laying stages. To study the pol
