FOXM1 and pemphigus foliaceus: Importantly, we finally showed that FoxM1 proteins could be directly associated with promoter region of the β‐catenin in mouse lung pericytes by both EMSA and ChIP‐PCR assays, which validated the roles of β‐catenin in PF development, as well as the diversity of molecular mechanisms underlying FoxM1 and β‐catenin‐mediated lung pericyte fibrosis.
