S-acetyl-glutathione selectively induces apoptosis in human lymphoma cells through a GSH-independent mechanism.

Reduced apoptosis is associated to cancer development. Agents able to restore the programmed cell death responsiveness of cancer cells are foreseen as potential effective cancer therapies. In this study, we report that a glutathione-S-derivative, S-acetyl-glutathione (Sag), induces significant apoptosis in three human lymphoma cell lines, including Daudi, Raji and Jurkat cells while it had no or little effect on either Hut-78 lymphoma cells or the normal BT lymphocytes.
