CoCl2 simulated hypoxia induce cell proliferation and alter the expression pattern of hypoxia associated genes involved in angiogenesis and apoptosis

Biol. Res; 52 (), 2019
BACKGROUND/AIMS: Hypoxia microenvironment plays a crucial role during tumor progression and it tends to exhibit poor prognosis and make resistant to various conventional therapies. HIF-1α acts as an important transcriptional regulator directly or indirectly associated with genes involved in cell prolife...

The role of ischemic preconditioning in the expression of apoptosis-related genes in a rat model of intestinal ischemia-reperfusion injury

Acta cir. bras; 34 (5), 2019
Abstract Purpose: To analyze the effects of ischemic preconditioning (IPC) in the expression of apoptosis-related genes in rat small intestine subjected to ischemia and reperfusion. Methods: Thirty anesthetized rats underwent laparotomy and were drive into five groups: control (CG); ischemia (IG); is...

Genes related to maintenance of autophagy and successful aging

Arq. neuropsiquiatr; 76 (12), 2018
ABSTRACT Considering aging as a phenomenon in which there is a decline in essential processes for cell survival, we investigated the autophagic and proteasome pathways in three different groups: young, older and oldest old male adults. The expression profile of autophagic pathway-related genes was carrie...

The apoptotic, angiogenic and cell proliferation genes CD63, S100A6 e GNB2L1 are altered in patients with endometriosis

Abstract Objective The aim of the present study was to analyze the expression of the CD63, S100A6, and GNB2L1genes, which participate in mechanisms related to the complex pathophysiology of endometriosis. Methods A case-control study was conducted with 40 women who were diagnosed with endometriosis, ...

Genetic variants related to angiogenesis and apoptosis in patients with glioma

Arq. neuropsiquiatr; 76 (6), 2018
ABSTRACT Background Glioma, the most common primary malignant brain tumor in adults, is highly aggressive and associated with a poor prognosis. The objectives of this study were to evaluate the association of genetic polymorphisms related to angiogenesis and apoptosis with gliomas, as well as comorbidi...

Protective effects of Tribulus terrestris hydroalcoholic extract against cisplatin-induced germ cell apoptosis in male mice

Int. j. morphol; 36 (1), 2018
SUMMARY: Toxic effects of anti-cancer and other drugs on the normal tissues could be reduced by the herbal plants and their fractions. This study investigated the protective effect of Tribulus terrestris (TT) on Cisplatin- induced cytotoxicity germ cell apoptosis in male mice. In this experimental study,...

Circular RNA hsa_circ_0000523 regulates the proliferation and apoptosis of colorectal cancer cells as miRNA sponge

Braz. j. med. biol. res; 51 (12), 2018
Among the novel class of endogenous long non-coding RNAs, circular RNA (circRNA) is known as a key regulator in the development and progression of different cancers. Its function and mechanism in the tumorigenesis of colorectal cancer, however, has not been well studied. This study thus aimed to investig...

Knockdown of long non-coding RNA ANRIL inhibits tumorigenesis in human gastric cancer cells via microRNA-99a-mediated down-regulation of BMI1

Braz. j. med. biol. res; 51 (10), 2018
Long non-coding RNA antisense non-coding RNA in the INK4 locus (ANRIL) has been reported to promote tumorigenesis via regulating microRNA (miR)-99a in gastric cancer cells. However, the role of each component involved in it is still not well understood. This study aimed to verify the role of ANRIL in gas...

Mechanistic effect of the human GJB6 gene and its mutations in HaCaT cell proliferation and apoptosis

Braz. j. med. biol. res; 51 (9), 2018
We constructed lentiviral vectors containing the human wild-type GJB6 gene and the mutant variants A88V and G11R. The three proteins were stably expressed by the Tet-on system in the HaCaT cell line and used to study the functional effect of the variants. The CCK-8 assay and flow cytometric analyses were...

MicroRNA-122 regulates caspase-8 and promotes the apoptosis of mouse cardiomyocytes

Braz. j. med. biol. res; 50 (2), 2017
Cardiomyocyte apoptosis plays key roles in the pathogenesis of heart diseases such as myocardial infarction. MicroRNAs are important regulators of gene expression, which are also involved in the regulation of cardiomyocyte apoptosis. However, cardiomyocyte apoptosis regulated by microRNA (miR)-122 is lar...
