NAP1L2 and myalgic encephalomeyelitis/chronic fatigue syndrome: Ectopic expression of miR-27b-3p significantly suppressed the luciferase activity of wild-type (WT) NAP1L2 reported gene, this was disappeared in mutant NAP1L2 reported gene (Additional file 2: Fig. S6C, D), suggesting that miR-30a-5p negatively regulated the expression of NAP1L2 in CFs.
