VEGFA and renal cell carcinoma: The analysis revealed that mast cell immune- and carcinoma-associated pathways were most abundant in the low-risk group, including the VEGF signaling pathway [55], TGF beta signaling pathway [56], proteasome [57], cytokine–cytokine receptor interaction [58], and RCC, whereas autophagy-associated pathways were mainly enriched in the high-risk group.
