Fig. 6: SPARCL1 regulates BMP7 expression and BMP/TGF-β cell signaling pathway.

a, d shows the protein expression of BMP7 regulated by SPARCL1 activation and inhibition, respectively. C2C12 cells were induced to differentiate at 72 h. pSPgRNA-S-2 is the SPARCL1 activation group, while pSPgRNA is the blank control for SPARCL1 activation. NC is the negative control for SPARCL1 siRNA interference. b, c are greyscale scans of SPARCL1 and BMP7 proteins in A. e, f are grayscale scans of SPARCL1 and BMP7 proteins in D. i and p shows changes in the expression of BMP/TGF-β-associated proteins when SPARCL1 was activated and inhibited, respectively, and C2C12 cells were induced to differentiate at 72 h. pSPgRNA-S-2 is the SPARCL1 activation group, while pSPgRNA is the blank control for SPARCL1 activation. NC is the negative control for SPARCL1 siRNA interference. j–o are greyscale scans of proteins in I. q–v are greyscale scans of proteins in P. **P values < 0.01 were considered as significant
