The findings demonstrated that the gene expression of KRAS (p = 1.1e − 149), MAP3K1 (p = 5.7e − 29), MAPK8 (p = 5e − 04), RASGRP1 (p = 2.9e − 111), and SOS2 (p = 7.8e − 31) was considerably upregulated in BC as compared to the normal tissue. This evidence concerns the gene RASGRP1 and breast cancer.
