Association between single nucleotide polymorphisms and endometriosis in a brazilian population

Abstract Objective To investigate the association between genetic polymorphisms in candidate genes or candidate regions and the development of endometriosis in Brazilian women. Methods A total of 30 women between 25 and 64 years old with a diagnosis of endometriosis participated in the present study, a...

The branched-chain amino acid transaminase 1 -23c/g polymorphism confers protection against acute coronary syndrome

Rev. invest. clín; 72 (1), 2020
ABSTRACT Background: Previous studies have shown an association between polymorphisms of the BAT1-NF-κB inhibitor-like-1 (NFKBIL1)-LTA genomic region and susceptibility to myocardial infarction and acute coronary syndrome (ACS). Objective: The objective of the study was to study the role of three ...

Association of il-8 -251t>a (rs4073) polymorphism with susceptibility to gastric cancer: a systematic review and meta-analysis based on 33 case-control studies

Arq. gastroenterol; 57 (1), 2020
ABSTRACT BACKGROUND: The role of -251A>T polymorphism in the anti-inflammatory cytokine interleukin-8 (IL-8) gene in gastric cancer was intensively evaluated, but the results of these studies were inconsistent. OBJECTIVE: Therefore, we performed a meta-analysis to provide a comprehensive data on t...

Association between estrogen, vitamin d and microrna17 gene polymorphisms and periapical lesions

Braz. dent. j; 31 (1), 2020
Abstract This study evaluated the association between polymorphisms in genes encoding estrogen receptors 1 (ESR1) and 2 (ESR2), vitamin D receptor (VDR) and in microRNA17 (which binds to ESR1 and VDR) with persistent apical periodontitis (PAP) after the endodontic treatment. We included 162 patients who ...

Association between matrix metalloproteinase-9 gene polymorphism and breast cancer in Brazilian women

Clinics; 75 (), 2020
OBJECTIVE: This study aimed to determine the relationship between rs17576 (MMP-9) polymorphism and increased cancer risk in a Brazilian breast cancer cohort. METHODS: This study included 141 women (71 breast cancer patients and 70 controls without breast cancer) who donated 3 mL of their peripheral bloo...

Estudio de frecuencia y asociación de los polimorfismos RS965513 y RS1867277 del gen FOXE1 con el carcinoma papilar de tiroides y su riesgo de recurrencia en población chilena

Introducción: El gen FOXE1 (Forkhead box E1) codifica para un factor de transcripción involucrado en la morfogénesis tiroidea. El cáncer papilar de tiroides (CPT) se ha asociado con polimorfismos (SNP) de FOXE1 rs1867277 y rs965513 en población asiática y europea. Nuestro objetivo fue investigar la...

Association of TLR3 single nucleotide polymorphisms with susceptibility to HTLV-1 infection in Iranian asymptomatic blood donors

Abstract INTRODUCTION: The human T-lymphotropic virus type 1 (HTLV-1) has a single-stranded RNA genome and expresses specific proteins that have oncogenic potential. Approximately 15 to 20 million people worldwide have been infected by this virus. Changes in protein or gene expression are the effects of...

Enfermedad celíaca y desarrollo de patologías secundarias

Med. lab; 24 (4), 2020
La enfermedad celíaca es una patología autoinmune sistémica caracterizada por un estado inflamatorio crónico de la mucosa y submucosa intestinal, de origen multifactorial y detonada por factores ambientales como la ingesta de gluten en individuos genéticamente predispuestos a sensibilizarse a dicha ...

Deep sequencing of small RNAs reveals the repertoire of miRNAs and piRNAs in Biomphalaria glabrata

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND Biomphalaria glabrata snails are widely distributed in schistosomiasis endemic areas like America and Caribe, displaying high susceptibility to infection by Schistosoma mansoni. After the availability of B. glabrata genome and transcriptome data, studies focusing on genetic markers and small n...

The APOB rs693 polymorphism impacts the lipid profile of Brazilian older adults

Braz. j. med. biol. res; 53 (3), 2020
The apolipoprotein B (APOB) gene contains several polymorphic sites described as risk modifiers for cardiovascular events. The objective of this study was to verify the association of the classic APOB Xba I polymorphism (rs693) with atherosclerotic risk factors in a segment of the Brazilian elderly popul...
