MKI67 and neoplasm: Consistently, IHC staining of xenograft tissues revealed an increase in Ki67 expression in the anlotinib group following transfection with the METTL3 lentivirus compared to that in tumours in the anlotinib group transfected with the control lentivirus, whereas this expression was reduced in tissues co‐transfected with the shPRKDC lentivirus (Figure 7F).
