Identification of blood-derived candidate gene markers and a new 7-gene diagnostic model for multiple sclerosis

Biol. Res; 54 (), 2021
BACKGROUND: Multiple sclerosis (MS) is a central nervous system disease with a high disability rate. Modern molecular biology techniques have identified a number of key genes and diagnostic markers to MS, but the etiology and pathogenesis of MS remain unknown. RESULTS: In this study, the integration of t...

Identification of potential molecular mechanisms and small molecule drugs in myocardial ischemia/reperfusion injury

Braz. j. med. biol. res; 53 (9), 2020
Myocardial ischemia/reperfusion (MI/R) injury is a complex phenomenon that causes severe damage to the myocardium. However, the potential molecular mechanisms of MI/R injury have not been fully clarified. We identified potential molecular mechanisms and therapeutic targets in MI/R injury through analysis...

Genome-wide DNA methylation profile in the peripheral blood of cocaine and crack dependents

Objective: Cocaine use disorders (CUDs) represent a major public health problem in many countries. To better understand the interaction between the environmental modulations and phenotype, the aim of the present study was to investigate the DNA methylation pattern of CUD patients, who had concomitant coc...

Discovery and molecular analysis of conserved circRNAs from cashmere goat reveal their integrated regulatory network and potential roles in secondary hair follicle

Background: Circular RNAs, a novel class in the eukaryotic transcriptome, are characterized by the 3′ and 5′ ends that are covalently joined in a covalently closed loop without free ends. Circular RNAs are considerably stable molecules and act as microRNA sponges with regulatory potential to the prot...

Analysis of the transcriptional regulatory mechanisms mediated by microRNAs in Metabolic Syndrome

Metabolic Syndrome (MetS) is a combination of diseases interrelated and associated with increased mortality and risk of cardiovascular events. Among the elucidated molecular mechanisms of MetS, there are several genes regulated by miRNAs - small non-coding RNAs. A large number of transcriptomic studies i...

Identification of the targets of hematoporphyrin derivative in lung adenocarcinoma using integrated network analysis

Biol. Res; 52 (), 2019
BACKGROUND: Hematoporphyrin derivative (HPD) has a sensibilization effect in lung adenocarcinoma. This study was conducted to identify the target genes of HPD in lung adenocarcinoma. METHODS: RNA sequencing was performed using the lung adenocarcinoma cell line A549 after no treatment or treatment with X-...

Expression analysis of long non-coding RNAs in a renal ischemia-reperfusion injury model

Acta cir. bras; 34 (4), 2019
Abstract Purpose: To investigate the long non-coding RNAs (lncRNAs) profile on renal ischemia reperfusion in a mouse model. Methods: Microarray analysis was used to study the expression of misregulated lncRNA in a mouse model of renal ischemia reperfusion(I/R) with long ischemia time. Quantitative re...

Identification of key genes involved in nasopharyngeal carcinoma

Abstract Introduction: Nasopharyngeal carcinoma is the most common cancer originating from the nasopharynx. Objective: To study the mechanisms of nasopharyngeal carcinoma, we analyzed GSE12452 microarray data. Methods: GSE12452 was downloaded from the Gene Expression Omnibus database and included 31 n...
