Nevertheless, we identified that, at baseline conditions, SOX2‐OT variant 1 positively correlates, while SOX2‐OT variant 6 negatively correlates, with mRNA SOX2/GLI‐1 expression, in A549 cells, compared with a heterogeneous expression level in different lung cancer cells (Fig. S2A,B). This evidence concerns the gene GLI1 and lung cancer.
