sh‐c‐Myb or PD‐L1 alone into FLO‐1 cells increased Fas, IFN‐γ, and IL‐2 expression, but decreased FasL, IL‐4, and IL‐10 expression in the tumor tissues, and cotransfection of sh‐c‐Myb and PD‐L1 showed more significant trends compared with transfection of sh‐c‐Myb or PD‐L1 alone (Figure 9F & G). Here, IL4 is linked to neoplasm.
