More importantly, in our clinic breast tumor tissues, we found that c-Myc protein were much higher in lncRNA KB-1980E6.3-high tumor tissues than those in lncRNA KB-1980E6.3-low tumor tissues (Fig. 4g), and there was a positive correlation between lncRNA KB-1980E6.3 levels and c-Myc protein scores (Fig. 4h). The gene discussed is MYC; the disease is breast neoplasm.
