Finally, considering the role of the EGFR signaling pathway in numerous human cancer symptoms—for example, cancer metastasis, tumor invasion and angiogenesis (not including tumor growth), [29] as well as other types of tumors, including lung cancer [36], breast cancer [37], prostate cancer [38], colon cancer [39], gastric cancer [40], glioma [41], melanoma [42], etc.—it is reasonable to speculate whether WB-308 may have effects on EGFR signaling pathway-related human cancer types. This evidence concerns the gene EGFR and central nervous system cancer.
