A Germline-Encoded lncRNA-Mitochondrial Axis Rewires Oxidative Phosphorylation to Drive Progression in Clear Cell Renal Cell Carcinoma.

Inherited ccRCC risk variant rs234043 represses LINC02068, leading to mitochondrial oxidative phosphorylation attenuation and tumor progression.

• Why it matters: Understanding how germline genetic variation influences tumor metabolism could enable targeted therapies for ccRCC, addressing a key gap in precision oncology.
• What they did: The study integrated genome sequencing and transcriptomics from ccRCC tissues, identifying rs234043 as a causal variant that recruits HOXC8 to repress LINC02068, affecting mitochondrial function.
• The result: Reduced LINC02068 promotes malignant phenotypes and adverse outcomes, while pharmacologic inhibition of mitochondrial complex I suppresses ccRCC cell migration and proliferation, suggesting new therapeutic avenues.
