Various non-coding RNAs are abnormally expressed in BC and their expression levels are associated with the clinico-pathological features of the patients. For example, Increased lncRNA ABHD11-AS1 represses the malignant phenotypes of BC [12], Tetracycline-inducible shRNA targeting antisense lncRNA HIF1A-AS2 represses the malignant phenotypes of BC [13]. This evidence concerns the gene HIF1A and breast cancer.
