Outline of Final Research Achievements

Cadmium exposure is known to increase lung cancer risk, but the underlying molecular mechanisms in cadmium-stimulated progression of malignancy are unclear. Here, we examined the effects of prolonged cadmium exposure on the malignant progression of A549 human lung adenocarcinoma cells and the roles of Notch1, HIF-1α, and PI3K/Akt/ERK signaling pathways. As a result, we found that Notch1, along with HIF-1α and PI3K/Akt/ERK signaling pathways, promotes malignant progression stimulated by prolonged cadmium exposure in A549 cells.
