Figure 8. The graphic illustrates the signaling pathways impacted by MPMCA, leading to the suppression of osteoclast activity. MPMCA hinders the transformation of macrophages into osteoclasts and intensifies the cell apoptosis of mature osteoclasts. MPMCA facilitates the inhibition of MAPKs (ERK, p38 and JNK) and NF-κB signaling pathways.
