Serum gastrin levels in the fed state were lower in antrectomy rats compared to controls but did not differ in the fasting rats. Pancreas and colon were heavier in all hypergastrinemic rats.
WebAnimal models are an indispensable resource for investigating the causes of gastric cancer, ... A notable exception is male-predominant disease expression in hypergastrinemic INS-GAS mice on the FVB strain background (Fox, Rogers et al. 2003; Fox, Wang et al. 2003). WebIn this animal model it is possible to study the effects of hypergastrinemia without gastric hypoacidity, mimicking human gastrinomas. Young INS-GAS mice have an increased ECL cell number and a proportion of these mice develop adenocarcinomas in the gastric corpus at the end of their lifespan [ 39 ].
