Immunostaining of Ki-67 and Kindlin-2 in dissected tumors showed that silencing of lnc-ATB inhibited proliferation and Kindlin-2 of ESCC cells (Figures 7f–h), indicating that knockdown of lnc-ATB significantly suppressed tumor growth via miR-200b/Kindlin-2 in vivo. Here, MKI67 is linked to esophageal squamous cell carcinoma.
