Avaliação do perfil de microRNAs exossomais em portadores de hipercolesterolemia familial

A Hipercolesterolemia Familial (HF) é uma doença hereditária do metabolismo lipídico que causa aos portadores alta incidência de aterosclerose prematura. A HF pode ser diagnosticada clínica e geneticamente, entretanto, apenas cerca de 40% podem ter confirmados pelo diagnostico molecular. Assim, out...

Expression of LIN28A/B and Let-7 miRNAs in canine mammary carcinomas

Ciênc. rural (Online); 52 (10), 2022
LIN28 is a RNA-binding protein including two highly conserved homologous, LIN28A and LIN28B. Proto-oncogenes such as LIN28A and LIN28B are generally targeted by the let-7 miRNAs in different types of human cancers. Here, we determined the expression of LIN28A in canine mammary tumor samples and the LIN28...

Expression of AIF, PARP, and miRNAs MIR-145, MIR-210, and MIR-486 associated with apoptosis in the corpus cavernosum of rats subjected to chronic alcoholism model

Int. j. morphol; 38 (6), 2020
SUMMARY: Previous studies from our group described the consequences of using ethanol on penile erection. Nevertheless, the molecular mechanisms surrounding microRNAs, apoptosis process and their relationship with erectile dysfunction associated with alcohol consumption are still poorly understood. The ob...

Expression profile of salivary micro RNA-21 and 31 in oral potentially malignant disorders

Abstract Oral potentially malignant disorders (OPMD) possess significant chances of malignancy conversion. In order to develop an early diagnostic tool, the present study evaluated the expression of miRNA-21 and 31 as salivary markers. The case-control study was carried out in 36 healthy participants as ...

Morphological and molecular analysis of apoptosis in the corpus cavernosum of rats submitted to a chronic alcoholism model

Acta cir. bras; 35 (3), 2020
Abstract Purpose To evaluate the effect of chronic alcoholism on morphometry and apoptosis mechanism and correlate with miRNA-21 expression in the corpus cavernosum of rats. Methods Twenty-four rats were divided into two experimental groups: Control (C) and Alcoholic group (A). After two weeks of an ...

The effect of Maras powder and smoking on the microRNA deregulation of oral mucosa

J. appl. oral sci; 28 (), 2020
Abstract Objective This study aimed to investigate the effects of Maras powder (a type of smokeless tobacco obtained from Nicotiana rustica Linn and mixed with the ashes of wood, especially from oak, walnut or grapevine) on the microRNA (miRNA) deregulation of oral mucosa, and it compares these effects...

Micro RNA 146a-5p expression in Kidney transplant recipients with delayed graft function

J. bras. nefrol; 41 (2), 2019
ABSTRACT Introduction: The development of novel non-invasive biomarkers of kidney graft dysfunction, especially in the course of the delayed graft function period would be an important step forward in the clinical practice of kidney transplantation. Methods: We evaluated by RT-PCR the expression of miR...

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...

Effect of lncRNA HULC knockdown on rat secreting pituitary adenoma GH3 cells

Braz. j. med. biol. res; 52 (4), 2019
Pituitary adenoma is one of the most common tumors in the neuroendocrine system. This study investigated the effects of long non-coding RNAs (lncRNAs) highly up-regulated in liver cancer (HULC) on rat secreting pituitary adenoma GH3 cell viability, migration, invasion, apoptosis, and hormone secretion, a...

Astragalus polysaccharides decrease proliferation, migration, and invasion but increase apoptosis of human osteosarcoma cells by up-regulation of microRNA-133a

Braz. j. med. biol. res; 51 (12), 2018
Osteosarcoma (OS) has a high incidence, malignity, and frequency of recurrence and metastasis. In this study, we aimed to explore the potential anti-cancer effects of Astragalus polysaccharides (APS) on human OS MG63 cells as well as underlying mechanisms. Viability of MG63 cells was assessed by CCK-8 as...
