Fig. 5From: Knockdown of CD44 inhibits proliferation, migration and invasion of osteosarcoma cells accompanied by downregulation of cathepsin SCD44 knockdown downregulated the expression of cathepsin S in MG63 and U2OS cells. A mRNA expression levels of CD44, cathepsin S, and β-actin were detected by RT-qPCR. B Protein expression levels of CD44, cathepsin S, and β-actin were detected by Western blotting. **P < 0.01 versus control groupBack to article page
