Similarly, we found that LBX2‐AS1 expression levels in four commercially purchased human ovarian cancer cell lines (SKOV3, OVCAR‐3, Caov‐3 and ES‐2) were significantly higher than that in one non‐malignant human ovarian epithelial cell line (HOSEPICs), as shown in Figure 1D. This evidence concerns the gene LBX2 and ovarian carcinoma.
