The peroxisome proliferator ciprofibrate induces hypergastrinemia and as a consequence, enterochromaffin-like (ECL) cell hyperplasia. The mechanism for the gastrin cell stimulation is unknown. The somatostatin analog octreotide LAR (long-acting release) was used to see if the stimulating effects of ciprofibrate could be attenuated. Female Fischer rats were dosed with ciprofibrate (50 mg/kg body weight per day) alone or combined with octreotide LAR (10 mg/30 days) for 60 days. Plasma gastrin and histamine, gastric endocrine cell densities and mRNA abundances were measured. Ciprofibrate increased gastrin mRNA abundance (P&lt;0.05), gastrin cell number (P&lt;0. 001) and cell area (P&lt;0.01), and induced hypergastrinemia (P&lt;0.001). These rats had profound ECL cell hyperplasia, confirmed by an increase in chromogranin A (CgA) and histidine decarboxylase (HDC) mRNA, density of neuroendocrine and ECL cells and plasma histamine levels (all P&lt;0.001). Octreotide LAR did not affect ciprofibrate stimulation of gastrin cells, but all parameters of ECL cell hyperplasia were reduced (P&lt;0.001). Octreotide LAR also significantly inhibited basal ECL cell function and growth. Ciprofibrate stimulates gastrin cell activity by a mechanism unaffected by octreotide, but octreotide does inhibit basal and gastrin-stimulated ECL cell function and growth.

Octreotide inhibits the enterochromaffin-like cell but not peroxisome proliferator-induced hypergastrinemia
