a RIP experiments were performed using an antibody against AGO2 on extracts from preadipocytes. b LncRIP was performed using a RP11-142A22.4-specific probe and control probe in preadipocytes from obesity patients. The enrichment of RP11-142A22.4 and microRNAs was detected by RT-qPCR and normalized to the control probe. c Co-localization between RP11-142A22.4 and miR-587 was observed by RNA in situ hybridization in preadipocytes. Nuclei were stained with DAPI. Scale bar = 20 µm. d Schematic showing the predicted miR-587 sites in RP11-142A22.4. A Luciferase assay where preadipocytes were co-transfected with a scrambled control, miR-587 mimic, and a luciferase reporter plasmid containing wild-type RP11-142A22.4 (RP11-142A22.4-WT) (e) or mutant RP11-142A22.4 (RP11-142A22.4-mut) (f). g Expression of miR-587 was analyzed using RT-qPCR following RP11-142A22.4 knockdown. h RT-qPCR showed the level of RP11-142A22.4 in the streptavidin-captured fractions from the preadipocytes lysates after transfection with biotinylated miR-587 or control RNA. i Pearson correlation between RP11-142A22.4 expression and miR-587 expression in the adipose tissues of 60 obese patients using qRT-PCR. Data are presented as means ± SD; significant difference was identified with Student’s t test. *P < 0.05; **P < 0.01; ns, not significant.
