Background: Triglycerides (TG) are one of the major constituents of body fat and energy reservoir, which consist of an ester derived from glycerol and three free fatty acids. TG lipase, monoacylglycerol lipase, fatty acid synthase, and HMG-CoA reductase are some of the key enzymes related to TG metabolism, and their roles in colorectal cancer (CRC) initiation and progression are under investigation.

Methods: The literature search was performed based on various published papers, mostly on triglyceride metabolism relevant to CRC in PubMed, Google Scholar and other search engines. The gene expression profiling of some of the TG metabolic pathway mediators was performed by transcriptomic and/or proteomic data from The Cancer Genome Atlas (TCGA) database using R program and cBioportal software.

Results And Discussion: Accumulating pieces of evidence suggest that TG profiling may be used as a biomarker for the diagnosis and/or prognosis of CRC. Dysregulation of TG metabolism is associated with the initiation and progression of CRC. Most of the TG anabolic pathway mediators are overexpressed and/or overactivated during CRC tumorigenesis, while most TG catabolic pathway mediators are downregulated and/or inactivated based on literature search and correlated with TCGA data. Metabolic enzymes of TG and FAs metabolic pathways are involved in CRC tumor growth survival and metastasis.

Conclusion: Overall studies from the previous literature and our TCGA data analysis demonstrated that the area of research on TG-associated lipid metabolic pathways holds great promise and warranted detailed investigations in this area for the implementation of novel preventive and therapeutic strategies against CRC.
