Further, the pathways involved in the RAS gene were analyzed, and the five most significant pathways were identified including Thyroid cancer (p = 1.01e-7), Bladder cancer (p = 1.38e-7), Endometrial cancer (p = 4e-7), VEGF signaling pathway (p = 4.21e-7), Long-term depression (4.43e-7), and the overlap of four pathways with BRAF, which indicates that these genes play a key role in the cancer development. This evidence concerns the gene VEGFA and thyroid cancer.
