UCA1 and hepatocellular carcinoma: Furthermore, Figure 1J demonstrated the expression of UCA1 was higher in two parental cells (HepG2 and SMMC‐7721) compared with normal liver cells (HL‐7702) (p < 0.05), and the expression of UCA1 was further higher in two OXA‐resistant cells (HepG2/OXA and SMMC‐7721/OXA) compared with their parental counterparts (p < 0.001), suggesting the potential involvement of UCA1 in OXA resistance of HCC.
