Sirtuin 1 (SIRT1) Protein Degradation in Response to Persistent c-Jun N-terminal Kinase 1 (JNK1) Activation Contributes to Hepatic Steatosis in Obesity
Open accessAbstract
SIRT1 is involved in the pathogenesis of obesity, diabetes, and aging. However, it is not clear how SIRT1 activity is regulated by intracellular kinases in cells. In this study, we investigated SIRT1 phosphorylation and protein degradation in response to JNK1 activation in obese mice. Mouse SIRT1 is phosphorylated by JNK1 at Ser-46 (Ser-47 in human SIRT1), which is one of the four potential residues targeted by JNK1. The phosphorylation induces a brief activation of SIRT1 function and degradation of SIRT1 thereafter by the proteasome. Ubiquitination occurs in SIRT1 protein after the phosphorylation. Mutation of Ser-46 to alanine prevents the phosphorylation, ubiquitination, and degradation. In vivo, SIRT1 undergoes an extensive degradation in hepatocytes in obesity as a consequence of persistent activation of JNK1. The degradation leads to inhibition of SIRT1 function, which contributes to development of hepatic steatosis. The degradation disappears in obesity when JNK1 is inactivated in mice. JNK2 exhibits an opposite activity in the regulation of SIRT1 degradation. The JNK1-SIRT1 pathway provides a new molecular mechanism for the pathogenesis of hepatic steatosis in obesity.

“Furthermore, persistent activation of JNK and/or p38K is positively associated with various liver diseases such as steatohepatitis and I/R injury [122], [123], [124], [125], suggesting the clinical importance of JNK and p38K in human disease states, as reviewed [126].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
