LBX2-AS1 and ovarian carcinoma: Considering that qRT‐PCR results presented in Figure 1D have shown that, among the four ovarian cancer cell lines we have examined, LBX2‐AS1 expression levels in SKOV3 and OVCAR‐3 cells were higher than that in the Caov‐3 and ES‐2 cells, we chose the SKOV3 and OVCAR‐3 cells as models for further LBX2‐AS1 knockdown.
