The rate of pJNK positivity in osteosarcoma cells with high LRP1–SNRNP25 expression was significantly higher than that in the corresponding control cells (80% vs. 40%), and MMP2 expression was also higher in cells with high LRP1–SNRNP25 expression (100% vs. 30%) (Fig. 5B). This evidence concerns the gene MMP2 and osteosarcoma.
