Metastasis causes most cancer deaths and reflects transitions from primary tumor escape to seeding and growth at metastatic sites. Epithelial-to-mesenchymal transition (EMT) is important early in metastasis to enable cancer cells to detach from neighboring cells, become migratory, and escape the primary tumor. While different phases of metastasis expose cells to variable nutrient environments and demands, the metabolic requirements and plasticity of each step are uncertain.

Hereditary Leiomyomatosis and Renal Cell Cancer (HLRCC) is an inherited cancer syndrome caused by germline pathogenic variants in the fumarate hydratase (FH) gene. Affected individuals are at risk for developing cutaneous and uterine leiomyomas and aggressive FH-deficient renal cell carcinoma (RCC) with a papillary histology. Due to a disrupted TCA cycle, FH-deficient kidney cancers rely on aerobic glycolysis for energy production, potentially creating compensatory metabolic vulnerabilities.

Article Synopsis
  • The study focuses on malignant transformation (MT) in IDH-mutant gliomas, emphasizing the need to understand the mechanisms behind MT and intervene at early stages.
  • Researchers created two 3D cell models (403L and 403H) from the same patient's IDH-mutant glioma, representing low-grade (LGG) and high-grade (HGG) tumors, allowing for comparison of genetic and metabolic changes.
  • The findings indicate that the high-grade model (403H) is more aggressive, showing increased cell invasion and distinct metabolic alterations, providing a new framework for investigating MT in gliomas.

Hypoxic tumor microenvironments pose a significant challenge in cancer treatment. Hypoxia-activated prodrugs like evofosfamide aim to specifically target and eliminate these resistant cells. However, their effectiveness is often limited by reoxygenation after cell death.
