For early markers (collagen type 2, aggrecan, SOX9, and HIF1α), gene expression in BC and IC conditions (both contained TGFβ3 and Dex) was always higher than those of BM and IM conditions (except for HIF1α where the expression in the BC condition was similar to those of BM and IM). This evidence concerns the gene TGFB3 and breast cancer.
