Functional pathway analysis revealed differences between WTC EHC breast cancer and WTC EHC cancer-free women among several gene pathways, including endocytosis, proteoglycans in cancer, regulation of actin cytoskeleton, axon guidance, focal adhesion, calcium signaling, cGMP-PKG signaling, mTOR, Hippo, and oxytocin signaling, among others (Figure 2). This evidence concerns the gene MTOR and breast carcinoma.
