Shun-saku Takahashi, Yu-Shin Sou, Tetsuya Saito, Akiko Kuma, Takayuki Yabe, Yuki Sugiura, Hyeon-Cheol Lee, Makoto Suematsu, Takehiko Yokomizo, Masato Koike, Shuji Terai, Noboru Mizushima, Satoshi Waguri, Masaaki Komatsu Autophagy regulates fatty acid and triglyceride synthesis at the transcriptional level by fine-tuning the levels of NCoR1, a negative regulator of nuclear receptors. Defective autophagy impairs physiological steatosis both under fasting conditions and after hepatectomy. -- Delivered by Feed43 service ..read more
