1 OBJECTIVE: A possible inhibition of SREBP-1c-dependent genes by the protease inhibitor indinavir and its possible reversal by the lipid-lowering drug simvastatin were studied. Indinavir sterol regulatory element binding transcription factor 1 Homo sapiens
2 METHODS: The effects of indinavir and simvastatin on the inhibition/activation of SREBP-1c-dependent genes were compared with the effects of indinavir and simvastatin on the inhibition/activation of SREBP-1c-independent genes. Indinavir sterol regulatory element binding transcription factor 1 Homo sapiens
3 RESULTS: Indinavir inhibited the SREBP-1c-dependent genes encoding the lipoprotein lipase (103 nmol/l resulted in an inhibition of 12.4%; P = 0.0051) and the fatty acid synthase (103 nmol/l resulted in an inhibition of 30.3%; P = 0.036) in a dose-dependent fashion but not the SREBP-1c-independent gene encoding the low-density lipoprotein receptor. Indinavir sterol regulatory element binding transcription factor 1 Homo sapiens
4 RESULTS: Indinavir inhibited the SREBP-1c-dependent genes encoding the lipoprotein lipase (103 nmol/l resulted in an inhibition of 12.4%; P = 0.0051) and the fatty acid synthase (103 nmol/l resulted in an inhibition of 30.3%; P = 0.036) in a dose-dependent fashion but not the SREBP-1c-independent gene encoding the low-density lipoprotein receptor. Indinavir sterol regulatory element binding transcription factor 1 Homo sapiens
5 Simvastatin antagonized the indinavir-induced SREBP-1c-inhibition. Indinavir sterol regulatory element binding transcription factor 1 Homo sapiens
6 CONCLUSIONS: Indinavir inhibits important effector genes of the SREBP-1c pathway, explaining major HAART-related adverse effects. Indinavir sterol regulatory element binding transcription factor 1 Homo sapiens
