In the tumor samples from NOD/SCID mice injected with A549-Luc-CXCL13 cells (Figure 6—figure supplement 1D,E) and BaP-treated Cxcr5+/+ mice (Figure 6—figure supplement 1F,G), the expression of E-Cadherin was low, while the N-Cadherin and nuclear β-catenin were high. The gene discussed is CXCR5; the disease is neoplasm.
