Figure 5From: Proton pump inhibitors (PPIs) impact on tumour cell survival, metastatic potential and chemotherapy resistance, and affect expression of resistance-relevant miRNAs in esophageal cancerEffect of PPI treatment on extracellular proton concentration. The figure presents the concentration of protons in the extracellular space (culture medium) after 72 hour PPI treatment (LD50) in SCC (A) and EAC (B) cells. *: statistically significant different compared to control (p ≤ 0.001).Back to article page
