Abstract:
Fatty liver disease is a common chronic liver disease which is mainly induced by abnormal lipid metabolism. To find out the effect of GP73 on lipid metabolism in the liver, we constructed a high GP73 expression liver model through a tail vein injection of AAV-GP73 into eight-week-old C57BL/6J mice. Liver lipid metabolomics analysis showed that lipids in the liver of mice, especially the triglycerides, were significantly increased. In addition, kyoto encyclopedia of genes and genomes enrichment analysis showed that GP73 altered lipid metabolites profile that may further disturb many signaling pathways related to cellular metabolism. The diseases linked to type II diabetes, non-alcoholic fatty liver disease (NAFLD) and choline metabolism in cancer cells were more likely to be dysregulated. Thus, GP73 may induce fatty liver by regulating lipid metabolism and promoting lipid accumulation in the liver.

Lipolysis: The Breakdown of Lipids:
Lipolysis is the process of breaking down lipids, particularly triglycerides, into glycerol and fatty acids. This process typically occurs in the adipose tissue and is triggered by various hormones, including glucagon and...
Blood Studies for Cardiovascular System III: Serum Lipid Profile
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
Smooth Endoplasmic Reticulum
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...
