胃泌素及其受体与胃癌关系的研究进展

胃泌素主要由胃窦及小肠上段黏膜的G细胞分泌,其受体分布在多种器官组织中.胃泌素及其受体具有调节细胞生长、分化,抑制细胞凋亡,促进细胞增生、侵袭、转移的功能.研究表明,胃泌素及其受体参与包括胃癌在内的多种肿瘤的发生、发展.胃泌素及其受体还可作为胃癌早期诊断的一个重要指标,同时也可能是胃癌治疗的潜在靶点.本文就胃泌素及其受体与胃癌的发生、发展关系作一综述.

The Effects of Capsaicin on Gastrin Secretion in Isolated Human Antral Glands: Before and After Ingestion of Red Chilli

Background Capsaicin is known to have regulatory effects on gastrointestinal functions via the vanilloid receptor (VR1). We reported previously that endocrine-like cells in the human antrum express VR1. Aim To identify VR1-expressing endocrine-like cells in human antral glands and to examine whether stimulation with capsaicin causes release of gastrin, somatostatin, and serotonin. Further, to investigate the effects of a chilli-rich diet. Methods Gastroscopic biopsies were received from 11 volunteers. Seven of the 11 subjects agreed to donor gastric biopsies a second time after a 3-week chilli-rich diet containing 1.4–4.2 mg capsaicin/day. VR1-immunoreactive cells were identified by double-staining immunohistochemistry against gastrin, somatostatin, and serotonin. For the stimulation studies, we used an in vitro method where antral glands in suspension were stimulated with 0.01 mM capsaicin and physiological buffer was added to the control vials. The concentrations of secreted hormones were detected and calculated with radioimmunoassay (RIA). Results The light microscopic examination revealed that VR1 was localized in gastrin cells. The secretory studies showed an increase in release of gastrin and somatostatin compared to the control vials (P = 0.003; P = 0.013). Capsaicin-stimulation caused a consistent raise of the gastrin concentrations in the gland preparations from all subjects. A chilli-rich diet had an inhibitory effect on gastrin release upon stimulation compared to the results that were obtained before the start of the diet. Conclusion This study shows that capsaicin stimulates gastrin secretion from isolated human antral glands, and that a chilli-rich diet decreases this secretion.     

Radioimmunoassay of Gastrin: Specificity of Gastrin Antisera

Antisera for use in a gastrin radioimmunoassay have been prepared in two ways and their specificity compared. Antibodies to porcine antral gastrin were found to be specific for the N-terminal portion of the molecule; there was no cross-reaction with pentagastrin or pancreozymin. Antibodies to the C-terminal gastrin tetrapeptide, however, cross-reacted with pentagastrin and pancreozymin on an equimolar basis. Neither antiserum cross-reacted with secretin, insulin, or glucagon. The gastrin-specific antiserum can be used in a sensitive and specific radioimmunoassay for gastrin.
