Myostatin coordinating the proliferation and differentiation of adipose and skeletal muscle cells and energy metabolism balance based on gene chip technology

Rev. bras. med. esporte; 27 (spe2), 2021
ABSTRACT Myoblasts fuse into multinucleated muscle fibers to form and promote the growth of skeletal muscle. In order to analyze the role of myostatin (MSTN) in body fat, skeletal muscle cell proliferation and differentiation and energy metabolism, this study will use the antisense RNA technology of gene...

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...

Housekeeping genes involved in non-malignant breast phenotypes are widely expressed in multiple cancers and provide novel biomarkers of tumor classification

Braz. j. med. biol. res; 54 (7), 2021
Clinically relevant biomarkers are useful to determine cancer patients' prognosis and treatments. To discover new putative biomarkers, we performed in silico analysis of a 325-gene panel previously associated with breast epithelial cell biology and clinical outcomes. Sixteen public datasets of microarray...

Visible DNA microarray and loop-mediated isothermal amplification (LAMP) for the identification of Cryptococcus species recovered from culture medium and cerebrospinal fluid of patients with meningitis

Braz. j. med. biol. res; 53 (11), 2020
Cryptococcal meningitis affects normal hosts and immunocompromised patients exhibiting high mortality rates. The objective of this study was to design two molecular assays, visible microarray platforms and loop-mediated isothermal amplification (LAMP), to identify Cryptococcus spp. and the species neofor...

Gene expression analysis identifies hypothetical genes that may be critical during the infection process of Xanthomonas citri subsp. citri

Background: Gene expression analysis via microarray is widely used in phytobacteria to validate differential gene expression associated with virulence or to compare biological profiles of wild type and mutant strains. Here, we employed DNA microarrays to study the early stages of the infection process (2...

Whole sequencing of the mitochondrial genome of breast cancer tissue in Mexican-mestizo postmenopausal women with different body mass index

Rev. invest. clín; 71 (4), 2019
Abstract Background Mitochondrial and oxidative stress has been related to obesity and breast cancer being this cancer more frequent and more aggressive in postmenopausal women with obesity. Objective The objective of this study was to investigate whether Mexican-Mestizo postmenopausal women with breas...

Transcriptional profiling of uterine leiomyoma rats treated by a traditional herb pair, Curcumae rhizoma and Sparganii rhizoma

Braz. j. med. biol. res; 52 (6), 2019
The aim of this study was to elucidate the concise effects of a traditional herb pair, Curcumae rhizoma-Sparganii rhizoma (CRSR), on uterine leiomyoma (UL) by analyzing transcriptional profiling. The UL rat model was made by intramuscular injection of progesterone and gavage administration of diethylstil...

Portación de fimH en aislados de Escherichia coli productor de Toxina Shiga provenientes de ganado bovino, Departamento Cordillera, Paraguay

Ciertas cepas de Escherichia coli productoras de toxina Shiga (STEC) tienen la capacidad de formar biofilm en alimentos y otras superficies, aumentando su potencial como fuente de contaminación. El gen fimH se ha asociado a la capacidad de formación de biofilm en E.coli. Este estudio observacional desc...

Genomic imbalances in syndromic congenital heart disease

J. pediatr. (Rio J.); 93 (5), 2017
Abstract Objective: To identify pathogenic genomic imbalances in patients presenting congenital heart disease (CHD) with extra cardiac anomalies and exclusion of 22q11.2 deletion syndrome (22q11.2 DS). Methods: 78 patients negative for the 22q11.2 deletion, previously screened by fluorescence in situ h...

How to detect new viral outbreaks or epidemics? We need to survey the circulation of viruses in humans and other animals using fast, sensible, cheap, and broad-spectrum methodologies
