WNT7A-IN-1 (1365-0109), a WNT7A inhibitor, disrupts the protein–protein interaction between WNT7A and its receptor FZD5, resulting in the upregulation of MHC-I expression. WNT7A-IN-1 (1365-0109) significantly increases the expression of MHC-I and p-p65,while concurrently reducing the expression of active β-catenin.
