Ten of these ncRNAs (miRs-93-5p, 103a-3p, 126-3p, 146b-5p, 205-5p, 944, 1254, and 1285-3p, and snoRA21 and snoRA80) showed increased expression, whereas two ncRNAs (miR-4251 and snoRA3) had decreased expression in WA patients with lung cancer when compared with cancer-free AA smokers. The gene discussed is SNORA21; the disease is lung cancer.
