Fatty acids as potential adjunctive colorectal chemotherapeutic agents

Area of Science:

• Biochemistry
• Oncology
• Molecular Biology

Background:

• Fatty acids (FA) are bioactive molecules with potential as adjunctive chemotherapeutic agents.
• FA are classified by carbon chain length: short, medium, and long.
• Previous studies show FA induce apoptosis in various cancer cell types in vitro.

Purpose of the Study:

• To define the optimal fatty acid chain length for anti-neoplastic properties.
• To review existing evidence on the anti-cancer effects of different fatty acid chain lengths.
• To explore the potential of fatty acids in colorectal cancer (CRC) chemotherapy.

Main Methods:

• Literature review of studies on fatty acids and cancer.
• Analysis of in vitro and in vivo data on fatty acid cytotoxicity and apoptosis induction.
• Classification of fatty acids based on carbon chain length (short, medium, long).

Main Results:

• Short-chain fatty acids (e.g., butyrate) induce high rates of in vitro apoptosis via epigenetic modification and cell cycle arrest.
• Medium-chain fatty acids show cytotoxic and antimicrobial properties, with limited data on anti-neoplastic potential.
• Longer unsaturated fatty acids (C16-24) exhibit in vitro anti-proliferative effects through oxidative stress and signaling pathway modification.

Conclusions:

• Evidence suggests varying anti-neoplastic efficacy across different fatty acid chain lengths.
• Short-chain fatty acids show significant promise for inducing cancer cell apoptosis.
• Further research is needed to identify the most effective fatty acid chain length for cancer therapy, particularly in CRC.
