Efeito ByStander induzido por células-tronco mesenquimais irradiadas e sua influência na migração leucocitária

A medula óssea é um compartimento complexo do corpo humano com funções cruciais para manutenção da fisiologia hematopoética, tendo componentes protagonistas como as células-tronco hematopoéticas (CTHs) que participam ativamente da produção dos fatores sanguíneos, e as células-tronco mesenqui...

Catequinas del té verde: efectos antigenotóxicos y genotóxicos. Revisión sistemática

Arch. latinoam. nutr; 72 (3), 2022
Las catequinas del té verde (Camellia sinensis) (CTV) presentan efectos benéficos para la salud asociados a su potencial antioxidante. Por otra parte, el estrés oxidante es una de las vías de inducción de daño genotóxico. De ahí que, en la presente revisión se realizó un análisis de los efecto...

Evaluation of the cytotoxic and genotoxic effects by melamine and cyanuric acid co-exposure in human embryonic kidney 293 cells

Braz. j. med. biol. res; 53 (5), 2020
The melamine and cyanuric acid (CA) complex has been suggested to cause the toxic effects observed in melamine-contaminated food or milk. However, the cytotoxic and genotoxic effects of co-exposure to melamine and CA are not fully clear. Therefore, the cytotoxic effects of melamine and CA were first exam...

Genotoxicity effects on Geophagus brasiliensis fish exposed to Doce River water after the environmental disaster in the city of Mariana, MG, Brazil

Braz. j. biol; 79 (4), 2019
Abstract The Doce River basin has suffered the largest environmental accident ever occurred in Brazil with the influx of tailings from Fundão and Santarém, belonging to Samarco mining company, due to the disaster in Mariana. A spill between 50 and 60 million m3 of tailings was estimated by the company...

Efeitos citotóxicos da duloxetina nas linhagens celulares MKN45 e NIH3T3 e efeitos genotóxicos em linfócitos sanguíneos periféricos humanos

Arq. gastroenterol; 56 (4), 2019
ABSTRACT BACKGROUND: Gastric cancer is the second leading cause of cancer-related death globally. Unfortunately, the survival rate of the gastric cancer patients who underwent chemotherapy following surgery has been less than a half. Besides, chemotherapy has many side effects. Current evidence suggest...

Int. j. morphol; 36 (4), 2018
This study was aimed to search the effect of wheatgrass on the Total Antioxidan (TAS)-Oxidan Status (TOS) and DNA damage in rat with diabetes. The rats used in the study were randomly divided into 4 groups that each of has 10 rats: Control group; 1 ml single dose phosphate-citrate buffer injected i.p (pH...

Reduction of doxorubicin-induced genotoxicity by Handroanthus impetiginosus in mouse bone marrow revealed by micronucleus assay

Braz. j. biol; 78 (1), 2018
Abstract Handroanthus impetiginosus has long been used in traditional medicine and various studies have determined the presence of bioactive chemical compounds and potential phytotherapeutics. In this study, the genotoxicity of the lyophilized tincture of H. impetiginosus bark (THI) was evaluated in mous...

Cuban flora species as a potential source of DNA protective compounds

Environmental exposure to genotoxic agents represents a major health concern for modern society. DNA damage could lead to mutations, which accumulative effect is closely related to degenerative and lethal diseases, such as cancer. Because of their structural and chemical diversity natural products play a...

Oridonin induces growth inhibition and apoptosis in human gastric carcinoma cells by enhancement of p53 expression and function

Braz. j. med. biol. res; 51 (12), 2018
The tumor suppressive role of oridonin, an active compound extracted from Rabdosia rubescens, has been proven in several gastric cancer (GC) cell lines. The present study aimed to evaluate the effect of oridonin on another GC cell line, SNU-216, and explore the potential mechanisms. The viable cell numbe...
