1 Fenretinide induces ubiquitin-dependent proteasomal degradation of stearoyl-CoA desaturase in human retinal pigment epithelial cells. Fenretinide stearoyl-CoA desaturase Homo sapiens
2 We examined whether fenretinide, (N-(4-hydroxyphenyl)retinamide, 4HPR), which induces apoptosis in cancer cells and recently shown to improve insulin sensitivity, can modulate the expression of SCD. Fenretinide stearoyl-CoA desaturase Homo sapiens
3 We examined whether fenretinide, (N-(4-hydroxyphenyl)retinamide, 4HPR), which induces apoptosis in cancer cells and recently shown to improve insulin sensitivity, can modulate the expression of SCD. Fenretinide stearoyl-CoA desaturase Homo sapiens
4 We examined whether fenretinide, (N-(4-hydroxyphenyl)retinamide, 4HPR), which induces apoptosis in cancer cells and recently shown to improve insulin sensitivity, can modulate the expression of SCD. Fenretinide stearoyl-CoA desaturase Homo sapiens
5 We observed that fenretinide decreased SCD protein and enzymatic activity in the ARPE-19 human retinal pigment epithelial cell line. Fenretinide stearoyl-CoA desaturase Homo sapiens
6 In addition, PYR41, an inhibitor of ubiquitin activating enzyme E1, blocked the fenretinide-mediated decrease in SCD. Fenretinide stearoyl-CoA desaturase Homo sapiens
7 Immunoprecipitation analysis using anti-ubiquitin and anti-SCD antibodies and the blocking of SCD loss by PYR41 inhibition of ubiquitination further corroborate that fenretinide mediates the degradation of SCD in human RPE cells via the ubiquitin-proteasome dependent pathway. Fenretinide stearoyl-CoA desaturase Homo sapiens
8 Immunoprecipitation analysis using anti-ubiquitin and anti-SCD antibodies and the blocking of SCD loss by PYR41 inhibition of ubiquitination further corroborate that fenretinide mediates the degradation of SCD in human RPE cells via the ubiquitin-proteasome dependent pathway. Fenretinide stearoyl-CoA desaturase Homo sapiens
9 Therefore, the effect of fenretinide on SCD should be considered in its potential therapeutic role against cancer, type-2 diabetes, and retinal diseases. Fenretinide stearoyl-CoA desaturase Homo sapiens
