Abstract:
... Amphotericin B (AmB), used for systemic fungal infections, has a limited clinical application because of its high nephrotoxicity. Natural antioxidant and anti-inflammatory substances have been widely studied for protection against drug-induced nephrotoxicity. α-Bisabolol (BIS) has demonstrated a nephroprotective effect on both in vitro and in vivo models. The aim of this work was to evaluate the e ...

Abstract:
... 2-Mercaptoethanol (2-ME) is often used as an antioxidant to optimize culture systems for in vitro oocyte maturation in livestock. However, the relationship between 2-ME and autophagy has not yet been elucidated. In this study, we hypothesized that 2-ME can promote porcine oocyte maturation in vitro by maintaining autophagy homeostasis. To test this hypothesis, we explored the effects of 2-ME on th ...
