Anticancer Activity of Modified Tongyou Decoction on Eca109 Esophageal Cancer Cell Invasion and Metastasis through Regulation of the Epithelial-Mesenchymal Transition Mediated by the HIF-1α-Snail Axis

Figure 6

MTD inhibited Snail and HIF-1α fluorescent signals in both normoxia and hypoxia (200x). Note: blue fluorescence was DAPI, the green labeled Snail and HIF-1α, respectively. “Merge” was the combination of blue and green signals.
