Transcriptome profiling and digital gene expression analysis of genes associated with salinity resistance in peanut

Background: Soil salinity can significantly reduce crop production, but the molecular mechanism of salinity tolerance in peanut is poorly understood. A mutant (S1) with higher salinity resistance than its mutagenic parent HY22 (S3) was obtained. Transcriptome sequencing and digital gene expression (DGE) ...

Identificação de marcadores moleculares de resposta ao tratamento neoadjuvante em pacientes com adenocarcinoma de reto

Pacientes com câncer de reto (CaRe) em estadio II ou III são tratados com radioquimioterapia neoadjuvante (nCRT), a qual é responsável pela diminuição de recidivas loco-regionais e amputação do esfíncter. A resposta à terapia é variável, incluindo aqueles que não respondem ao tratamento e os...

Trypanosoma cruzi transcriptome during axenic epimastigote growth curve

Mem. Inst. Oswaldo Cruz; 113 (5), 2018
BACKGROUND Trypanosoma cruzi is an important protozoan parasite and the causative agent of Chagas disease. A critical step in understanding T. cruzi biology is the study of cellular and molecular features exhibited during its growth curve. OBJECTIVES We aimed to acquire a global view of the gene expres...

Transcriptomic differential lncRNA expression is involved in neuropathic pain in rat dorsal root ganglion after spared sciatic nerve injury

Braz. j. med. biol. res; 51 (10), 2018
Dorsal root ganglia (DRG) neurons regenerate spontaneously after traumatic or surgical injury. Long noncoding RNAs (lncRNAs) are involved in various biological regulation processes. Conditions of lncRNAs in DRG neuron injury deserve to be further investigated. Transcriptomic analysis was performed by hig...

Determination of multidrug resistance mechanisms in Clostridium perfringens type A isolates using RNA sequencing and 2D-electrophoresis

Braz. j. med. biol. res; 51 (8), 2018
In this study, we screened differentially expressed genes in a multidrug-resistant isolate strain of Clostridium perfringens by RNA sequencing. We also separated and identified differentially expressed proteins (DEPs) in the isolate strain by two-dimensional electrophoresis (2-DE) and mass spectrometry (...

Identification of key genes and pathways involved in response to pain in goat and sheep by transcriptome sequencing

Biol. Res; 51 (), 2018
PURPOSE: This aim of this study was to investigate the key genes and pathways involved in the response to pain in goat and sheep by transcriptome sequencing. METHODS: Chronic pain was induced with the injection of the complete Freund's adjuvant (CFA) in sheep and goats. The animals were divided into four...

Bioinformatics analysis of microarray data to reveal the pathogenesis of diffuse intrinsic pontine glioma

Biol. Res; 51 (), 2018
BACKGROUND: Diffuse intrinsic pontine glioma (DIPG) is the main cause of pediatric brain tumor death. This study was designed to identify key genes associated with DIPG. METHODS: The gene expression profile GSE50021, which consisted of 35 pediatric DIPG samples and 10 normal brain samples, was downloaded...

Follow up of a robust meta-signature to identify Zika virus infection in Aedes aegypti: another brick in the wall

Mem. Inst. Oswaldo Cruz; 113 (6), 2018
The mosquito Aedes aegypti is the main vector of several arthropod-borne diseases that have global impacts. In a previous meta-analysis, our group identified a vector gene set containing 110 genes strongly associated with infections of dengue, West Nile and yellow fever viruses. Of these 110 genes, four ...

Transcriptome analysis of female and male flower buds of Idesia polycarpa Maxim. var. vestita Diels

Background: Idesia polycarpa Maxim. var. vestita Diels, a dioecious plant, is widely used for biodiesel due to the high oil content of its fruits. However, it is hard to distinguish its sex in the seedling stage, which makes breeding and production problematic as only the female tree can produce fruits, ...

Transcriptome differences between 20- and 3, 000-year-old Platycladus orientalis reveal that ROS are involved in senescence regulation

Background: Platycladus orientalis has an extremely long life span of several thousands of years, attracting great interests in the mechanisms involved in such successful senescence regulation and resistance at physiological and molecular levels. Results: The levels of reactive oxygen species (ROS) were ...
