Nitric oxide and tumor metabolic reprogramming.

Area of Science:

• Oncology
• Molecular Biology
• Cancer Metabolism

Background:

• Nitric oxide (NO) plays a complex role in tumor progression.
• Mechanisms linking NO to tumorigenesis, particularly metabolic reprogramming, require further elucidation.

Purpose of the Study:

• To review recent advances in understanding NO's role in cancer metabolic reprogramming.
• To highlight how NO influences cancer cell metabolism and the tumor microenvironment.

Main Methods:

• Literature review of recent research on NO and cancer metabolism.
• Discussion of NO's impact on glucose/glutamine utilization, mitochondrial function, and S-nitrosylation.

Main Results:

• NO influences glucose and glutamine metabolism in tumor cells.
• NO regulates mitochondrial function and dynamics, supporting cancer proliferation.
• NO-mediated metabolic changes affect the tumor microenvironment, promoting invasion and immune escape.

Conclusions:

• Metabolic reprogramming is a critical aspect of NO's multifaceted role in cancer.
• Protein S-nitrosylation is a central mechanism for NO-induced metabolic alterations.
• Further research into S-nitrosylation/denitrosylation is crucial for understanding NO's impact on cancer metabolism and the tumor microenvironment.
