Hepatic PPARα function is controlled by polyubiquitination and proteasome‐mediated degradation through the coordinated actions of PAQR3 and HUWE1

Zilong Zhao, Daqian Xu, Zheng Wang, Lin Wang, Ruomei Han, Zhenzhen Wang, Lujian Liao, Yan Chen – 13 January 2018 – Peroxisome proliferator‐activated receptor α (PPARα) is a key transcriptional factor that regulates hepatic lipid catabolism by stimulating fatty acid oxidation and ketogenesis in an adaptive response to nutrient starvation. However, how PPARα is regulated by posttranslational modification is poorly understood.

Cellular Membrane Trafficking Machineries Used by the Hepatitis Viruses

Jun Inoue, Masashi Ninomiya, Tooru Shimosegawa, Mark A. McNiven – 13 January 2018 – While the life cycles of hepatitis viruses (A, B, C, D, and E) have been modestly characterized, recent intensive studies have provided new insights. Because these viruses “hijack” the membrane trafficking of the host cell machinery during replicative propagation, it is essential to determine and understand these specific cellular pathways. Hepatitis B virus (HBV) and hepatitis C virus are well known as leading causes of liver cirrhosis and hepatocellular carcinoma.
