Comparative secretome analysis of rat stomach under different nutritional status

Abstract

The fact that gastric surgery is at the moment the most effective treatment to fight against obesity highlights the relevance of gastric derived proteins as potential targets to treat this pathology. Taking advantage of a previously established gastric explant model for endocrine studies, the proteomic analysis of gastric secretome was performed. To validate this gastric explant system for proteomic analysis, the identification of ghrelin, a classical gastric derived peptide, was performed by MS. In addition, the differential analysis of gastric secretomes under differential nutritional status (control feeding vs fasting vs re-feeding) was performed. The MS identified proteins are showed in the present manuscript. The data supplied in this article is related to the research article entitled "Comparative secretome analysis of rat stomach under different nutritional status" (L.L. Senin, A. Roca-Rivada, C. Castelao, J. Alonso, C. Folgueira, F.F. Casanueva, M. Pardo, L.M. Seoane Comparative secretome analysis of rat stomach under different nutritional status J. Proteomics (2015)).
