WEE1 and hepatocellular carcinoma: There are several limitations in this study, for example 1) because of the shortage of clinicopathological data, we could not explore the association between circ0013958 and TNM stage, as well as tumor grade in HCC though in vitro and in vivo assays demonstrated that elevated circ0013958 was correlated with poor prognosis; 2) WEE1 inhibitor was not applied in current study, while our western blot results showed the function of miR-532-3p in inhibiting WEE1 expression, which could be rescued by circ0013958.
