To understand the contribution of LINC00261 towards cancer progression and metastasis, we monitored the correlation of LINC00261 expression with that of TGFβ1 and the epithelial marker CDH1. In the non-cancerous control samples with high LINC00261 expression, we observed a strong negative and positive correlation with TGFβ1 and CDH1 expression, respectively (Figure 4A,B). This evidence concerns the gene TGFB1 and cancer.
