Fig. 7. MM2P interacted with FUS to stabilize SOX9 mRNA.

Fig. 7

a Pulldown assay followed by mass spectrometry identified the interaction between FUS and MM2P, which was confirmed by western blot. b, c RIP assay for the abundance of MM2P in FUS precipitates, and the abundance of SOX9 mRNA in the precipitates of FUS. d Pulldown assay for the abundance of SOX9 in the pulldown of the MM2P biotin group after silencing FUS. e RT-qPCR and western blot analysis of FUS mRNA and protein levels under MM2P depletion. f Levels of FUS and MM2P in IL-13/IL-4-induced M2 macrophages after silencing FUS. g Three potential FUS binding sites on SOX9 mRNA predicted by CLIP experimental data from Starbase3.0. h Pulldown-western blot assay for the enrichment of FUS in the pulldown of SOX9 mRNA. i RIP experiments confirmed the interaction between FUS and SOX9 mRNA at site 3 rather site 1 and 2. j SOX9 mRNA stability after Actinomycin D treatment, responding to FUS knockdown. k SOX9 mRNA and protein expressions under the silence of FUS in IL-13/IL-4-induced M2 macrophages. l mRNA stability of SOX9 in IL-13/IL-4-induced M2 macrophages, in response to MM2P knockdown. **P < 0.01. The error bar expressed as mean ± SD of three independent experiments in triplicates.
