As a researcher in the field of gastric cancer, I was interested in anti-cancer effect of pantoprazole. Most of works published about anti-cancer effects of pantoprazole in gastric context include SGC-7901 cell line. It is while we are using AGS cell line as a gastric model. I wonder if there are any special reasons behind choosing SGC-7901 instead of AGS. and if AGS could be used to study anti-cancer effects of pantoprazole.
