Thus, our experiments demonstrate that the C-terminal region of HIV-1 Tat is required to suppress Mn-SOD expression and to induce pro-oxidative conditions reflected by a drop in reduced glutathione ( GSH ) and the GSH:oxidized GSH ( GSSG ) ratio .
 ( protein: Tat, None) , ( protein: Mn-SOD, None) , ( protein: HIV-1 Tat, None) , ( protein: GSH, None) , ( protein: C-terminal region, None)
