Figure Lengend Snippet: Schematic illustration of EM2‐induced suppression of cancer through targeting MST1/2 and activation of the Hippo signaling pathway. EM2 directly targets MST1/2, enhancing its kinase activity to promote LATS and YAP phosphorylation. This cascade reduces YAP nuclear translocation and diminishes CTGF and CYR61 mRNA translation, thereby exerting a potent inhibitory effect on NSCLC progression.

Figure Lengend Snippet: Fig. 13. Anti-infl ammatory mechanism of C3G is associated with upregulation of the LXR -ABCG1 pathway which results in disrupting lipid rafts by de- pleting cholesterol, thereby suppressing the TLR4- mediated NF- B and IRF3 signaling pathways induced by LPS .
