Although researchers have found high expression of NRC-ST8SIA4-12, and low expression of circNRIP1, linc-GTF2H2-1, RP3-466P17.2, miR-4435-1, and SNORD55 in NSCLC TEPs, the mechanism of action of these genes in NSCLC remains unclear (Table 2). The gene discussed is SNORD55; the disease is non-small cell lung carcinoma.
