Lipin1 (phosphatidic acid phosphatase) is a key molecule in the cells with two functions: first, it converts phosphatidic acid into diacylglycerol in the cytosol which in turn makes triglycerides. Second, in nucleus lipin1 acts as a transcriptional factor which regulates the expression of genes involved in the fatty acid oxidation and lipid metabolism. Clinically, Lpin1 gene mutations have been detected in patients with severe rhabdomyolysis accompanied with aggregated and dysfunctional mitochondria in their type II muscle fiber. Previously, we have observed that mice with lipin1 deficiency had aggregated mitochondria and abnormal autophagosomes formations by electron microscopy. The mechanism underlying the …
