Summary
Hepatocellular carcinoma (HCC) involves altered choline metabolism, with increased lysophosphatidic acid (LPA) in liver, bile, and serum. This suggests LPA may drive HCC proliferation by activating specific receptors.
Area of Science:
- Hepatobiliary Medicine
- Oncology
- Metabolomics
Background:
- Hepatocellular carcinoma (HCC) is a prevalent liver cancer with poor outcomes.
- Previous studies indicated reduced phospholipid, fatty acid, choline, and bile acid metabolism in HCC.
- Understanding metabolic alterations is crucial for HCC development insights.
Purpose of the Study:
- To investigate metabolic reprogramming in hepatocellular carcinoma.
- To elucidate the role of choline and phospholipid metabolism in HCC pathogenesis.
Main Methods:
- Analysis of tumor, plasma, and bile samples from HCC patients and controls.
- Evaluation of phospholipid levels using enzyme-linked immunosorbent assay (ELISA) and high-performance thin-layer chromatography (HPTLC).
Main Results:
- A modified choline metabolic profile was observed in HCC patients.
- Increased levels of choline in tumor tissue, lysophosphatidylcholine (LPC) in bile, and lysophosphatidic acid (LPA) in liver, bile, and serum.
- Lysophosphatidic acid (LPA) synthesis was significantly elevated in all HCC sample types.
Conclusions:
- Hepatocellular carcinoma (HCC) is associated with significant reprogramming of choline and phospholipid metabolism.
- Elevated LPA may promote tumor growth and proliferation through autocrine/paracrine signaling.
- Further research is needed to fully understand the implications of these metabolic changes in HCC.

01:24Liver Regeneration
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are large...

01:24Cirrhosis II: Pathophysiology
Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...
01:24Overview of Lipid Metabolism
Lipid metabolism is a crucial process in the human body that involves the synthesis and degradation of lipids. This process is essential for energy production, cell membrane formation, and hormone production, among other functions.
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...

01:25Lipid Catabolism
Triglycerides serve as crucial long-term energy storage molecules in microorganisms, providing a dense source of metabolic energy. Their breakdown is mediated by lipases, which hydrolyze triglycerides into glycerol and free fatty acids. Each of these components follows distinct metabolic pathways, ultimately contributing to ATP synthesis and cellular energy homeostasis.Glycerol MetabolismGlycerol, released from triglyceride hydrolysis, is phosphorylated by glycerol kinase to form...
01:23Cirrhosis I: Introduction
Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...
01:58Cell Specific Gene Expression
Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...
