Abstract
Being a vital cellular process, COPII vesicle trafficking has been found plays a crucial role in liver metabolism. However, its functions and the underlying mechanisms in systemic metabolic homeostasis have not been fully understood. Here, with a newly identified gene trap zebrafish line (sec31anju221), we show that compromised COPII vesicle trafficking leads to biphasic abnormal hepatic metabolism. During the larval stage, deficiency of COPII-mediated trafficking leads to activation of unfolded protein reaction (UPR) and the development of hepatic steatosis. By using epistasis analysis, we found eIF2a/ATF4 branch serves as the primary effector for liver steatosis. In adult sec31anju221 fish, the hepatosteatosis was reversed and the phenotype swing to glycogenic hepatopathy. Proteomic profiling and biochemical assay indicate sec31anju221 fish are in a state of hypothyroidism. Moreover, our study showed thyroid hormone treatment alleviates the metabolic defects. This study provides insights into processes of liver diseases associated with vesicle trafficking impairments and has expanded our understanding of the pathological interplay between thyroid and liver.
