These seven proteins—(CRMP2, C-RAF, CYP17, c-KIT+ VEGFR, and HDAC9)were considered in this in silico study owing to their association with several cancers: breast cancer [19], liver cancer [20], prostate cancer [21], kidney cancer (for both C-KIT [22] and VEGFR [23]), and stomach cancer [24]. This evidence concerns the gene HDAC9 and gastric cancer.
