The Warburg Effect 97 Years after Its Discovery.

Area of Science:

• Oncology
• Cancer Metabolism
• Biochemistry

Background:

• Cancer cells display altered oxidative metabolism, a phenomenon known as the Warburg effect, involving increased aerobic glycolysis and impaired oxidative phosphorylation.
• This metabolic deregulation is driven by genetic alterations, including oncogene activation and loss of tumor suppressor genes.

Purpose of the Study:

• To review the principal metabolic and molecular variations in cancer cells contributing to their anomalous behavior.
• To discuss the implications of the Warburg effect in cancer development, susceptibility, and therapy.

Main Methods:

• Literature review and commentary on existing studies.
• Analysis of molecular and metabolic alterations in cancer cells.

Main Results:

• Cancer cells exhibit modified oxidative metabolism, with activated oncogenes promoting glycolysis and decreased oxygen consumption.
• Genetic susceptibility, molecular correlations, and defective mitochondria are linked to metabolic deregulation.
• The Warburg effect is reevaluated in light of recent studies, suggesting its epiphenomenal role in malignancy.

Conclusions:

• The Warburg effect, while a hallmark of cancer, is an epiphenomenon of the transformation process.
• Understanding cancer cell metabolic deregulation is vital for developing effective cancer prevention and treatment strategies.
