Tumor energy metabolism: implications for therapeutic targets

Area of Science:

• Oncology
• Metabolic pathways
• Epigenetics

Background:

• Tumor energy metabolism is critical for cancer growth, progression, and drug resistance.
• Epigenetic regulation significantly influences cancer cell metabolic reprogramming and traits.
• Targeting tumor metabolism is an emerging and vital strategy in cancer therapy.

Purpose of the Study:

• To review primary tumor energy metabolism pathways and their therapeutic targeting.
• To examine the role of the SWI/SNF complex in tumor metabolism.
• To discuss clinical significance, challenges, and future directions in targeting tumor metabolism.

Main Methods:

• Literature review of tumor energy metabolism pathways (glycolysis, Warburg effect, mitochondrial function, oxidative phosphorylation).
• Analysis of epigenetic regulation, focusing on the SWI/SNF complex's role in metabolic interactions.
• Synthesis of current and emerging therapeutic strategies targeting metabolic pathways and SWI/SNF.

Main Results:

• Key metabolic pathways like glycolysis and mitochondrial function are central to tumor adaptability.
• The SWI/SNF complex interacts with glucose, lipid, and amino acid metabolism in tumors.
• Therapeutic strategies include glycolysis inhibitors, mitochondrial drugs, and targeting metabolic vulnerabilities.

Conclusions:

• Targeting tumor metabolism and epigenetic regulators like SWI/SNF offers promising therapeutic avenues.
• Overcoming drug resistance and employing combination therapies are crucial for clinical success.
• Future research should leverage new technologies to advance cancer metabolism-targeted treatments.
