Summary
Aberrant lipid metabolism fuels colorectal cancer (CRC) progression. This review proposes eight new lipid metabolism-associated hallmarks of CRC, linking them to established cancer hallmarks.
Area of Science:
- Biochemistry
- Oncology
- Metabolomics
Background:
- Lipids are crucial for cellular functions including membrane homeostasis, energy metabolism, and cell signaling.
- Altered lipid metabolism is increasingly recognized in cancer development and progression.
- Colorectal cancer (CRC) exhibits significant metabolic reprogramming, including lipid metabolism changes.
Purpose of the Study:
- To review recent findings on the role of reprogrammed lipid metabolism in colorectal cancer.
- To propose novel lipid metabolism-associated hallmarks specific to CRC.
- To connect these proposed hallmarks with the established 'hallmarks of cancer'.
Main Methods:
- Comprehensive literature review of studies on lipid metabolism and colorectal cancer.
- Analysis of recent advances in lipidomics technologies for cancer research.
- Synthesis of evidence linking lipid alterations to cancer hallmarks.
Main Results:
- Reprogrammed lipid metabolism plays a pivotal role in CRC onset, progression, and tumorigenic properties.
- Key lipid-associated changes in CRC are not yet fully integrated with established cancer hallmarks.
- Eight novel lipid metabolism-associated hallmarks of CRC are proposed.
Conclusions:
- Lipid metabolism reprogramming is a critical driver of colorectal cancer.
- The proposed lipid metabolism-associated hallmarks provide a new framework for understanding CRC.
- These hallmarks highlight the importance of targeting lipid metabolism in CRC therapy.

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...

Lipids are large molecules that are generally not water-soluble. Since most of the digestive enzymes in the human body are water-based, there are specific steps the body must take to break down lipids and make them available for use.

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...

Dietary triglycerides from chyme in the duodenum are mixed with bile salts produced by the liver to emulsify fats. As a result, large droplets are broken down into smaller ones, increasing the surface area for enzymatic action. Once emulsified, pancreatic lipases hydrolyze the triglycerides into free fatty acids and monoglycerides.
These breakdown products bind with bile salts and lecithin to form micelles, which quickly pass between microvilli to come in close contact with the apical...

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
