Role of reactive oxygen species, glutathione and NF-kappaB in apoptosis induced by 3,4-methylenedioxymethamphetamine ("Ecstasy") on hepatic stellate cells.

"Ecstasy" (3,4-methylenedioxymethamphetamine, MDMA), is a derivative of amphetamine with hepatotoxic effects that has been shown to induce apoptosis of cultured liver cells. In the present work, we studied the role played by oxidative stress in the apoptotic response caused by MDMA on a cell line of hepatic stellate cells (HSC). MDMA-treatment provoked oxidative stress determined as reactive oxygen species (ROS) accumulation and decrease of intracellular reduced glutathione levels.

3,4-Methylenedioxymethamphetamine ("Ecstasy") induces apoptosis of cultured rat liver cells.

"Ecstasy" (3,4-methylenedioxymethamphetamine, MDMA) has been shown to be hepatotoxic for human users, but molecular mechanisms involved in this effect remained poorly understood. MDMA-induced cell damage is related to programmed cell death in serotonergic and dopaminergic neurons. However, until now there has been no evidence of apoptosis induced by MDMA in liver cells.
