In addition, the results of the expression analysis of lnc‐CYB561‐5 across TCGA cancers (tumour versus normal samples) was shown in Figure 1H, revealed that lnc‐CYB561‐5 was highly expressed in most malignant tumours, including bladder urothelial carcinoma, breast invasive carcinoma, cholangiocarcinoma and stomach adenocarcinoma. This evidence concerns the gene CYB561 and invasive breast carcinoma.
