1 Rosiglitazone increases indexes of stearoyl-CoA desaturase activity in humans: link to insulin sensitization and the role of dominant-negative mutation in peroxisome proliferator-activated receptor-gamma. Rosiglitazone stearoyl-CoA desaturase Homo sapiens
2 SCD mRNA expression increased by 48% after rosiglitazone (P < 0.01). Rosiglitazone stearoyl-CoA desaturase Homo sapiens
3 SCD and delta5-desaturase but not delta6-desaturase activity indexes were increased after rosiglitazone versus placebo (P < 0.01 and P < 0.05, respectively). Rosiglitazone stearoyl-CoA desaturase Homo sapiens
4 In the P467L PPARgamma carrier, SCD and delta5-desaturase activity indexes were exceptionally low but were restored (52- and 15-fold increases, respectively) after rosiglitazone treatment. Rosiglitazone stearoyl-CoA desaturase Homo sapiens
5 This study shows for the first time that rosiglitazone increases SCD activity indexes and gene expression in humans. Rosiglitazone stearoyl-CoA desaturase Homo sapiens
6 An increased SCD activity index may reflect increased lipogenesis and might contribute to insulin sensitization by rosiglitazone. Rosiglitazone stearoyl-CoA desaturase Homo sapiens
7 The restored SCD activity index after rosiglitazone in PPARgamma mutation supports a pivotal role of PPARgamma function in SCD regulation. Rosiglitazone stearoyl-CoA desaturase Homo sapiens
8 The restored SCD activity index after rosiglitazone in PPARgamma mutation supports a pivotal role of PPARgamma function in SCD regulation. Rosiglitazone stearoyl-CoA desaturase Homo sapiens
