Implication

Experimental study demonstrates that chronic hypergastrinaemia disrupts gastric cell differentiation in transgenic mice, suggesting gastrin promotes immature mucosal cell expansion.

Key Points

To evaluate the long-term biological effects of sustained hypergastrinaemia on gastric mucosal morphology and epithelial cell differentiation.
Generated hypergastrinaemic transgenic mice harboring a mutated human gastrin gene, resulting in homozygous serum gastrin concentrations exceeding 600 pg/mL.
Examined stomach pathology in 30- to 35-week-old mice using histology, in situ hybridization for parietal cell H, K-ATPase mRNA, and in vivo gastrin binding assays.
Stomachs of 30- to 35-week-old transgenic mice were 30% to 50% heavier with markedly thickened mucosa, showing elongated proliferative pits and depleted glandular regions.
Parietal cell H, K-ATPase mRNA expression decreased markedly, and gastrin binding localized predominantly to prepit cells in the mid-glandular region without elevations in progastrin or glycine-extended gastrin.
