Analysis of gene expression changes associated with human carcinoma-associated fibroblasts in non-small cell lung carcinoma

Biol. Res; 50 (), 2017
BACKGROUND: This study aimed to investigate the gene expression changes associated with carcinoma-associated fibroblasts (CAFs) involving in non-small cell lung carcinoma (NSCLC). METHODS: We downloaded the GEO series GSE22862, which contained matched gene expression values for 15 CAF and normal fibrobla...

Expression of cocaine- and amphetamine-regulated transcript (CART) in hen ovary

Biol. Res; 50 (), 2017
BACKGROUND: Cocaine- and amphetamine-regulated transcript (CART), discovered initially by via differential display RT-PCR analysis of brains of rats administered cocaine, is expressed mainly in central nervous system or neuronal origin cells, and is involved in a wide range of behaviors, such as regulati...

De novo transcriptome assembly, functional annotation and differential gene expression analysis of juvenile and adult E. fetida, a model oligochaete used in ecotoxicological studies

Biol. Res; 50 (), 2017
BACKGROUND: Earthworms are sensitive to toxic chemicals present in the soil and so are useful indicator organisms for soil health. Eisenia fetida are commonly used in ecotoxicological studies; therefore the assembly of a baseline transcriptome is important for subsequent analyses exploring the impact of ...

Isolation of high-quality RNA from Platycladus orientalis and other Cupressaceae plants

Electron. j. biotechnol; 19 (5), 2016
Platycladus orientalis has a lifespan of several thousand years in China, making it a good plant in which to study aging at the molecular level, but this requires sufficient quantities of high-quality P. orientalis RNA. However, no appropriate methods have been reported for total RNA isolation from P. or...

Determinação do perfil de expressão de miRNA dos carcinomas gástricos de pacientes submetidos à quimioterapia neoadjuvante

INTRODUÇÃO: O tratamento do carcinoma gástrico (CG) é complexo e requer recursos intensivos. Atualmente, a cirurgia é a única opção curativa disponível para o tratamento de pacientes com CG. Na última década observou-se um grande avanço no tratamento multimodal destes pacientes devido ao reco...

Analyzing gene expression profiles in dilated cardiomyopathy via bioinformatics methods

Braz. j. med. biol. res; 49 (10), 2016
Dilated cardiomyopathy (DCM) is characterized by ventricular dilatation, and it is a common cause of heart failure and cardiac transplantation. This study aimed to explore potential DCM-related genes and their underlying regulatory mechanism using methods of bioinformatics. The gene expression profiles o...

Ropinirole alters gene expression profiles in SH-SY5Y cells: a whole genome microarray study

Braz. j. med. biol. res; 49 (2), 2016
Ropinirole (ROP) is a dopamine agonist that has been used as therapy for Parkinson's disease. In the present study, we aimed to detect whether gene expression was modulated by ROP in SH-SY5Y cells. SH-SY5Y cell lines were treated with 10 µM ROP for 2 h, after which total RNA was extracted for whole geno...

Wnt-5a-regulated miR-101b controls COX2 expression in hippocampal neurons

Biol. Res; 49 (), 2016
BACKGROUND: Wnt-5a is a member of the WNT family of secreted lipoglycoproteins, whose expression increases during development; moreover, Wnt-5a plays a key role in synaptic structure and function in the adult nervous system. However, the mechanism underlying these effects is still elusive. MicroRNAs (miR...

Candidate genes and pathogenesis investigation for sepsis-related acute respiratory distress syndrome based on gene expression profile

Biol. Res; 49 (), 2016
BACKGROUND: Acute respiratory distress syndrome (ARDS) is a potentially devastating form of acute inflammatory lung injury as well as a major cause of acute respiratory failure. Although researchers have made significant progresses in elucidating the pathophysiology of this complex syndrome over the year...

Conserved genes and pathways in primary human fibroblast strains undergoing replicative and radiation induced senescence

Biol. Res; 49 (), 2016
BACKGROUND: Cellular senescence is induced either internally, for example by replication exhaustion and cell division, or externally, for example by irradiation. In both cases, cellular damages accumulate which, if not successfully repaired, can result in senescence induction. Recently, we determined the...
