(A) Schematic illustration of SC collection from Pax7-nGFP mice. Fixed quiescent SCs (QSC), freshly isolated SCs (FISC), and cultured SCs (ASC) were subject to RNA-seq, western blotting (WB), and Immunofluorescence (IF) analyses. (B) The expression dynamics of m6A writer, reader, and eraser proteins in the above cells from analyzing the RNA-seq data. (C) Representative RNA-seq tracks showing the expression dynamics of the selected m6A regulators. (D) The expression dynamic of Ythdc1 mRNA (FPKM) from RNA-seq. (E) WB showing the induction of YTHDC1, YTHDF1, and YTHDF2 proteins upon SC activation and proliferation. * denotes the correct position of YTHDC1. Histone H3 was used as a loading control. (F) IF staining showing the induction of YTHDC1 protein upon SC activation and proliferation. Scale bar = 20 μm. (G) WB showing the predominant location of YTHDC1 in nuclear portion of C2C12 myoblasts.
