In addition, staining results of SIINFEKL-H2Kb complexes on cDC1 of TDLNs isolated from OVA-expressing tumor-bearing mice showed an increase in cross-presentation among hsBCL9z96-treated MC38-OVA tumor-bearing mice or Bcl9f/fBcl9lf/f Cre-ERT2 MC38-OVA tumor-bearing mice compared with vehicle or Bcl9f/fBcl9lf/fmice, respectively (Supplementary Fig. 5b, c). Here, MAPK3 is linked to neoplasm.
