Enlarged the regions of the 8 spots of interest in the sliver-stained SDS-polyacrylamide gels. The arrows indicated the spot of interest between OA+ESWT and OA groups. ESWT promoted two proteins up-regulation including Pdia-3 (P1529) and guanine nucleotide-binding protein subunit beta-2-like (P1981). Moreover, six proteins were identified that shockwave knee suppressed, including Beta-enolase (P1324), chloride intracellular channel protein 1 (P1325), malate dehydrogenase (P1408), purine nucleoside phosphorylase (P1409), creatine kinase M-type (P1412) and L-lactate dehydrogenase A chain (P1413). Black arrow indicated the position of interest spots.
