Metabolic Reprogramming in Ovarian Cancer Cells

Metabolic reprogramming has emerged as a defining feature of ovarian carcinoma, underpinning its rapid proliferation, survival in hostile microenvironments and propensity for chemoresistance. Rather than relying solely on mitochondrial respiration, many ovarian cancer cells adopt aerobic glycolysis—often referred to as the Warburg effect—to generate both energy and biosynthetic precursors. Simultaneously, subsets of tumours exploit oxidative phosphorylation (OXPHOS), fatty acid β-oxidation and glutamine-driven anaplerosis to meet the diverse demands of growth and dissemination. This metabolic heterogeneity is shaped by the peritoneal niche, where ascitic fluid, hypoxia and nutrient deprivation foster adaptive switches between energy pathways. Oncometabolites and reactive oxygen species act as signalling mediators, modulating epigenetic programmes and promoting metastatic traits. The dynamic interplay between glycolytic flux, mitochondrial function and lipid handling confers a survival advantage under chemotherapeutic stress. Understanding these interlinked pathways is critical for the development of targeted interventions that can thwart metabolic plasticity, overcome drug resistance and improve outcomes for patients with high-grade serous and other ovarian cancer subtypes.

Research from Nature Portfolio

Recent studies have revealed that fatty acid binding protein 4 (FABP4) plays a central role in metastatic progression by facilitating lipid transfer from adipocytes to ovarian tumour cells. Hypoxia-induced repression of miR-409-3p relieves its inhibition of FABP4, leading to enhanced fatty acid uptake, alterations in membrane composition and increased invasive potential. In preclinical models, delivery of miR-409-3p mimics or FABP4-targeted siRNA via nanoliposomes curtailed tumour growth and reshaped metabolic flux.

Complementary work on cellular bioenergetics has highlighted extensive heterogeneity among ovarian cancer lines. Chemoresistant populations adopt a high metabolically active phenotype capable of toggling between glycolysis and OXPHOS in response to nutrient availability. This metabolic flexibility underpins a robust ‘cellular fitness’ that enables survival under glucose deprivation and chemotherapy, suggesting that dual inhibition of glycolytic enzymes and mitochondrial respiratory complexes may be required to overcome resistance.

The graph below shows the total number of articles in metabolic reprogramming in ovarian cancer cells across all publications each year (not limited to Nature Index journals).

Technical terms

Warburg effect: The preference of cancer cells for aerobic glycolysis over mitochondrial respiration, yielding both ATP and anabolic precursors.

Oxidative phosphorylation (OXPHOS): Mitochondrial process by which electrons are transferred through respiratory complexes to generate ATP.

Anaplerosis: Metabolic pathways that replenish tricarboxylic acid (TCA) cycle intermediates consumed during biosynthesis.

Metabolic plasticity: The capacity of cells to switch between fuel sources (e.g. glucose, fatty acids, glutamine) in response to environmental stress.

Microenvironment: The local milieu of stromal cells, extracellular matrix, oxygen and nutrients surrounding a tumour.

miRNA: Small non-coding RNA molecules that regulate gene expression post-transcriptionally, often by targeting messenger RNA for degradation or translational repression.
