HEIH and melanoma: To explore whether the regulation of miR-200b/a/429 by lncRNA-HEIH also exists in clinical tissue samples, we measured the expression of miR-200b and analysed its correlation with lncRNA-HEIH in the same melanoma issues as shown in Figure 1A. qRT-PCR results showed that miR-200b is expressed lower in melanoma tissues than that in benign nevi (Figure 5A).
