COL11A1 and breast cancer: We confirmed that 5 genes, including COL11A1, GFAP, FGF5, CD300LG, and IGFL2, were co-expressed with WT1. In agreement with our results, the high expressions of WT1, COL11A1, and FGF5 in BC tumors have also been reported in previous literatures (Huang, Wang & Yang, 2018; Li, Kong & Zou, 2017a; Malvia et al., 2019).
