Brain cytoplasmic RNA 1 (BCYRN1) was a 200‐nucleotide LncRNA that had been reported to be up‐regulated in many malignant tumours, such as lung cancer, breast cancer and ovary carcinoma.48 Wang et al confirmed that BCYRN1 was increased in NSCLC, and its ability to induce proliferation and migration was largely due to up‐regulated expression of cell cycle‐related proteins (CDK4 and cyclin D1) and activation of the Wnt/β‐catenin signalling pathway.79 The gene discussed is BCYRN1; the disease is breast cancer.
