Regarding growth factors and their receptor genes, DOX increased EGF receptor (EGFR), ErbB2, ErbB4 (V-erb-b2 erythroblastic leukemia viral oncogene homolog 2 and 4), fibroblast growth factor 2 FGF2 and IGF-1 receptor (IGF-1R) in various tumors, while AN-152 therapy resulted in small increases in ErbB2, ErbB4 and FGF2 in HT-1197 cancers only (Fig. 4e). The gene discussed is ERBB2; the disease is cancer.
