RNA expression analysis of the tumour showed aberrant expression of VEGFA, a growth factor actively involved in vascular development13 (997.44 TPM, p = 0.041) and CD274 (also known as PD-L1), an immune checkpoint inhibitor14 (34.84 TPM, p = 0.002) (Fig. 3b, c). This evidence concerns the gene CD274 and neoplasm.
