The downregulated lncRNA–upregulated miRNA–downregulated mRNA network of differentially expressed genes between the MASLD + OSA and MASLD groups showed that downregulated Acap3 was regulated by downregulated lncRNAs, including TCONS_00111422, TCONS_00174363 and TCONS_00107558 and upregulated miR-34c-5p (Fig. 3e). This evidence concerns the gene ACAP3 and obstructive sleep apnea syndrome.
