We detected the expressions of LINC00365 and miR-221-5p in tumor tissues via PCR and found that miR-221-5p expression was upregulated in the tumor tissues of patients with high LINC00365 expression and that LINC00365 expression was positively correlated with miR-221-5p expression (r = 0.7681,P < 0.0001;Figure 4A). The gene discussed is LINC00365; the disease is neoplasm.
