in vitro maturation (ivm) is emerging as a popular technology at the forefront of fertility treatment and preservation. however, standard in vitro culture conditions usually increase reactive oxygen species (ros), which have been implicated as one of the major causes for reduced embryonic developmental competence. it is well-known that higher than physiological levels of ros triggers granulosa ...
Intracellular reactive oxygen species (ROS) play an important role in cancer stem cell (CSC) function. Hesperetin (Hst) is a flavonoid that has been shown to affect cellular ROS level. The goal of this study was to investigate the effect of Hst on the level of ROS in gastric CSCs (GCSCs). MTT assay was used to evaluate cell survival. Cellular ROS level was measured using 2′,7′-dichlorofluoresci...
infertility is one of the most stressful conditions amongst married couples. male factor infertility is implicated in almost half of these cases. recent advances in the field of reproductive medicine have focused the attention of many researchers to consider reactive oxygen species (ros) as one of the mediators of infertility causing sperm dysfunction. although, ros is involved in many physiolo...
Identification of Intracellular Sources Responsible for Endogenous Reactive Oxygen Species Formation
The endogenous reactive oxygen species ("ROS") formation is associated with many pathologic states such as inflammatory diseases, neurodegenerative diseases, brain and heart ischemic injuries, cancer, and aging. The purpose of this study was to investigate the endogenous sources for "ROS" formation in intact isolated rat hepatocytes, in particular, peroxisomal oxidases, monoamine oxidase, xanth...
Seizure activity has been proposed to result in the generation of reactive oxygen species (ROS), which then contribute to seizure-induced neuronal damage and eventually cell death. Although the mechanisms of seizure-induced ROS generation are unclear, mitochondria and cellular calcium overload have been proposed to have a crucial role. We aim to determine the sources of seizure-induced ROS and ...
fragrant species of the genus salvia have been attributed many medicinal properties, which include anticancer activity. in the present study, cytotoxic properties of total methanol extract of salvia chloroleuca rech. f. & aellen and its fractions were investigated on mcf-7, a breast carcinoma cell line. malignant and non-malignant cells were cultured in rpmi medium and incubated with different ...
Background and purpose: Hepatocellular carcinoma (HCC) is one of the most fatal cancers, so, proposing new anticancer agents is highly valuable. Production of reactive oxygen species (ROS) is increased in majority of cancers. Increase in ROS leads to cell damage and death. Aminoguanidine (AG) (pimagedine) is one of the compounds that can produce ROS at high concentrations. The present study was...
Recent studies have shown that reactive oxygen species (ROS) have a very important role in the intracellular signaling process in physiological conditions. On the other hand, during the recent decade it has been indicated that ROS play a role in various types of male infertility and it is due to the overproduction of ROS or decrease in the antioxidant defense system in the reproductive system a...
