We examined the expression of N-cadherin in liver cancer cells with HOTAIR overexpression (P-HOTAIR) or knockdown (Sh-HOTAIR) by immunofluorescence and found that compared with the NC group, the Sh-HOTAIR group showed reduced N-cadherin expression, while the P-HOTAIR group showed increased N-cadherin expression (Fig. 2H). Here, HOTAIR is linked to liver cancer.
