Clear cell renal cell carcinoma

Clear cell renal cell carcinoma (ccRCC) is the most prevalent and aggressive subtype of kidney cancer, and advanced disease is often marked by limited therapeutic response. It is characterized by metabolic reprogramming and an immunologically active but suppressive tumor microenvironment, with recent work linking upr signaling to immune regulation and macrophage polarization. Multi-omics profiling identified ectopic olfactory receptors as putative drivers of tumor progression and prognostic indicators, while the Key Facts note that bulk transcriptomic and single-cell multi-omics analyses supported OR-based prognostic modeling and tumor clustering with unfavorable prognostic signatures. Specific OR-related findings include or2t10 enrichment in malignant epithelial cells with invasive/metastatic potential and or51e1 expression in pericytes associated with vascular remodeling and angiogenic activity. Additional studies connect slc16a3-driven lactate remodeling to immune evasion via an autocrine GPR81-ERK-c-MYC feedback loop, and dock4 expression to favorable prognosis and immune infiltration. The disease context also includes signaling axes involving cebpb and mif, underscoring ccRCC as a major setting for biomarker discovery and immune-microenvironment research.

Tumor progression and prognosis
