GLI1 and skin basal cell carcinoma: To investigate the immunological modulation of BCC‐like tumors in mouse skin in response to ligand‐independent Hh/Gli activation, we treated 8‐week‐old K14CreERT;Ptchf/f (PtchΔep) mice with TAM to induce irreversible Hh/Gli activation and BCC‐like tumor formation, respectively.
