Conjugated Linoleic Acid in Cancer Therapy

Conjugated Linoleic Acid (CLA) is a polyunsaturated dietary fatty acid. Probiotics can biohydrogenate CLA with multiple health benefits, especially in cancer treatment. In vitro, in vivo, and clinical studies have confirmed CLA isomers to possess anti-cancer activity. CLA has demonstrated its potential as an alternative treatment for cancer and also used as an adjuvant to reduce the side effects of existing treatment methods. The mechanism of the anticancer activity of CLA is still not clear; however, it may involve intervention with the cell cycle and modulation of gene expression. A greater potential of CLA for cancer treatment has been supported by more and more clinical trials to evaluate its potential. Some advanced technologies are in progress to overcome the flaws of current methods and enhance the microbial production of CLA. In conclusion, nutritional enrichment as a functional food and direct consumption of CLA may contribute to cancer management.
