In another preclinical study of W0101, animal experiments of MCF-7 (breast cancer, IGF-1R 3+), CAOV3 (ovarian cancer, IGF-1R 2+), NCI-H2122 (lung cancer, IGF-1R 2+), SBC5 (lung cancer, IGF-1R 1+) and Hs746T (gastric cancer, IGF-1R−) were carried out. This evidence concerns the gene IGF1R and breast cancer.
