In our results, we observed that lead exposure inhibited the expression of p-MST and p-YAP in NF2-wildtype cells (Fig. 5) but showed no change in NF2-null CH157-MN cells (Fig. 5), suggesting that lead treatment alters the Hippo pathway through Merlin molecular specifically within meningiomas. The gene discussed is NF2; the disease is meningioma.
