LncRNAs have been proved to be critical for cancer cell survival and proliferation, like lncRNA brain cytoplasmic RNA 1 (BCYRN1 or BC200) was found to be dramatically upregulated in cultured tumor cells than normal cells, and knockdown of BC200 significantly inhibit the viability of cancer cells via arresting cell cycle and inducing apoptosis [91]. The gene discussed is BCYRN1; the disease is neoplasm.
