Another study by Dang et al. using bioinformatics analysis and microarray in PBMC cells of patients with chronic obstructive pulmonary disease (COPD) showed that miR-24-3p regulated CCL3, CCL4, IL-1β, and TNFαIP3 genes (Dang et al., 2017[6]). The gene discussed is CCL4; the disease is chronic obstructive pulmonary disease.
