In LN, we made two observations: (1) CD27+Ly6C+ cells expressed higher levels of Ki-67 than CD27+Ly6C− cells in both WT and tumor-bearing KB1P mice; and (2) CD27+Ly6C− and Ly6C+ cells from tumor-bearing KB1P mice expressed higher levels of Ki-67 than cells from WT mice (Figs. 5C and EV3F). This evidence concerns the gene CD27 and neoplasm.
