“… 5 , 6 , 7 In a separate study, we provide evidence that PMA increases Wnt signaling, which can be blocked by inhibitors of macropinocytosis, MVB formation, membrane trafficking, and lysosome acidification. 40 Here, we showed that addition of DAG strongly potentiates macropinocytosis and Wnt signaling. These findings have potential implications for the prevention of cancer progression.…”
