Anticancer, Antitumor, and Antioxidant Microbial Lipids: Mechanism of Action, Production, and Clinical Application

The present document highlights the significance of microbial lipids as new generation anticancer, antitumor, and antioxidant compounds. It focuses on the diverse nature of the action of these lipids in cancer treatment, especially polyunsaturated fatty acids (PUFAs). These mechanisms include membrane disruption, apoptosis/necrosis, DNA damage modifying histone and gene expression, angiogenesis inhibition, cell proliferation/cycle regulation, migration, invasion, metastasis, differentiation, reversal of drug resistance, and immune system modulation. The text also discusses the economical biosynthesis of these lipids via microbial fermentation, chemosynthesis, and other synthesis techniques. The versatility of PUFAs is described in detail in the following areas of study including signal transduction and inflammation. While microbial lipids offer potential cost-effectiveness due to scalable fermentation processes, it is important to note that specific clinical dosage regimens and comprehensive pharmacoeconomic comparisons with standard chemotherapeutic agents are still under investigation. Current estimates suggest lower long-term costs if optimized dosing is achieved, but further clinical trials are required to validate these economic benefits.
