Oleate (an SCD1 product) specifically activates SREBP-1 nuclear accumulation and restores SREBP-1 expression and de novo lipogenesis in SCD1-deficient hepatocytes. SCD1 deficiency increases polyunsaturated fatty acid content, which in turn drives increased β-oxidation. These effects were demonstrated using Scd1-deficient mice and transgenic mice with liver-specific oleate or palmitoleate production. |

SCD1 deficiency in skeletal muscle activates AMPK through an increase in AMP levels, while muscle-specific SCD1 overexpression decreases AMPK phosphorylation and the AMP/ATP ratio. AMPK changes caused by SCD1 modulation affect NAD+ levels and consequently SIRT1 activity and histone H3K9 acetylation/methylation status. |
