We showed that overexpression of TCF7L1 induced expression of LCN2 in vivo (Figure 10—figure supplement 1A) as previously reported (Miao et al., 2014) and that expression of LCN2 was also induced in murine skin papilloma and SCC (Figure 10C, Figure 10—figure supplement 1B) similarly to TCF7L1. The gene discussed is LCN2; the disease is skin papilloma.
