Abstract
Progressive destruction of pancreatic islet β-cells by immune cells is a primary feature of type 1 diabetes (T1D) and therapies that can restore the functional β-cell mass are needed to alleviate disease progression. Here, we report the use of mesenchymal stromal/stem cells (MSCs) for the production and delivery of Gastrin, a peptide hormone that is produced by intestinal cells and foetal islets and can increase β-Cell mass, to promote protection from T1D. A single injection of syngeneic MSCs that were engineered to express Gastrin (Gastrin-MSCs) caused a significant delay in hyperglycaemia in non-obese diabetic (NOD) mice compared to engineered control-MSCs. Similar treatment of early-hyperglycaemic mice caused the restoration of euglycemia for a considerable duration, and these therapeutic effects were associated with the protection of, and/or higher frequencies of, insulin-producing islets and less severe insulitis. While the overall immune cell phenotype was not affected profoundly upon treatment using Gastrin-MSCs or upon in vitro culture, pancreatic lymph node cells from Gastrin-MSC treated mice, upon ex vivo challenge with self-antigen, showed a Th2 and Th17 bias, and diminished the diabetogenic property in NOD-Rag1 deficient mice suggesting a disease protective immune modulation under Gastrin-MSC treatment associated protection from hyperglycaemia. Overall, this study shows the potential of production and delivery of Gastrin in vivo, by MSCs, in protecting insulin-producing β-cells and ameliorating the disease progression in T1D.

Gastrin: a distinct fate of neurogenin3 positive progenitor cells in the embryonic pancreas. PLoS One 2013; 8:e70397.

Abstract
Neurogenin3(+) (Ngn3(+)) progenitor cells in the developing pancreas give rise to five endocrine cell types secreting insulin, glucagon, somatostatin, pancreatic polypeptide and ghrelin. Gastrin is a hormone produced primarily by G-cells in the stomach, where it functions to stimulate acid secretion by gastric parietal cells. Gastrin is expressed in the embryonic pancreas and is common in islet cell tumors, but the lineage and regulators of pancreatic gastrin(+) cells are not known. We report that gastrin is abundantly expressed in the embryonic pancreas and disappears soon after birth. Some gastrin(+) cells in the developing pancreas co-express glucagon, ghrelin or pancreatic polypeptide, but many gastrin(+) cells do not express any other islet hormone. Pancreatic gastrin(+) cells express the transcription factors Nkx6.1, Nkx2.2 and low levels of Pdx1, and derive from Ngn3(+) endocrine progenitor cells as shown by genetic lineage tracing. Using mice deficient for key transcription factors we show that gastrin expression depends on Ngn3, Nkx2.2, NeuroD1 and Arx, but not Pax4 or Pax6. Finally, gastrin expression is induced upon differentiation of human embryonic stem cells to pancreatic endocrine cells expressing insulin. Thus, gastrin(+) cells are a distinct endocrine cell type in the pancreas and an alternative fate of Ngn3+ cells.

Abstract
Discovering the informational rule(s) underlying structure-function relationships in the protein language is at the core of biology. Current theories have proven inadequate to explain the origins of biological information such as that found in nucleotide and amino acid sequences. Here, we demonstrate that the information content of an amino acid motif correlates with the motif rarity. A structured analysis of the scientific literature supports the theory that rare pentapeptide words have higher significance than more common pentapeptides in biological cell 'talk'. This study expands on our previous research showing that the immunological information contained in an amino acid sequence is inversely related to the sequence frequency in the host proteome.

Abstract
The effects of cholecystokinin (CCK) and gastrin on proximal and distal colonic motility were investigated because of the possible role of these peptides in feeding-induced colonic motility. Experiments were performed using 22 chloralose-urethane anaesthetized cats in which the colon was acutely denervated. The volume changes of the proximal and distal colon were recorded with water-filled flaccid balloons. The venous effluxes from the proximal and distal colon were recorded separately using drop recorder units. CCK-8, I-200 pmol X min-I close i.a., and pentagastrin, I-200 pmol X min-I close i.a., evoked dose-dependent contractions of the colon without altering systemic arterial blood pressure and colonic blood flow. The CCK peptides -8, -33 and -39 produced contractions of similar magnitude in the proximal and distal colon. The stimulatory effect of CCK-8 and pentagastrin on colonic motility was blocked by tetrodotoxin (I microgram X kg-I i.a.) and hexamethonium (I0 mg X kg-I i.v.). Atropine (0.5 mg X kg-I i.v.) completely blocked the responses to CCK-8 and pentagastrin in the distal colon but only partially in the proximal colon. Additional administration of naloxone (I mg X kg-I i.a.) abolished the remaining contractile response to the peptides in the proximal colon. The present results support the idea that CCK and pentagastrin have a stimulatory effect on distal colonic motility mediated via preganglionic and postganglionic cholinergic pathways. The possible role of opioid peptides and cholinergic mechanisms in the proximal colon is discussed.

Abstract
The effects of synthetic human gastric I (SHG I) and gastrin-like pentapeptide (PG) on jejunal water, electrolyte, and glucose absorption were studied in 11 normal subjects. The i.v. administration of graded doses of SHG I increased plasma gastrin levels similar to those after food intake and in the Zollinger-Ellison syndrome. SHG I and PG caused no significant changes in the net movement of water and solute. The findings indicate that gastrin has no direct effect on intestinal absorption in normal man, and does not account for the mechanism of diarrhea in the Zollinger-Ellison syndrome.

Abstract
The purpose of this study was to determine the effect of bethanechol, gastrin I, or the octapeptide of cholecystokinin (CCK-OP) on the smooth muscle of the isolated cat colon. Myoelectrical activity was recorded with monopolar glass-pore electrodes. Slow-wave frequency was 5.9 +/- 0.2 cycles/min during the basal period. Slow waves were generally coupled during the control period and the apparent propagation velocity was predominantly aborad at a velocity of 3.8 +/- 0.4 mm/s. Spike activity was superimposed on 11.9 +/- 1.5% of the slow waves during the control period. Bethanechol stimulated a dose-dependent increase in colonic spike activity, with a threshold concentration of 10(-7) M. Bethanechol did not alter the congruence of the colonic slow-wave frequency at any concentration. Gastrin I or CCK-OP increased colonic spike activity. The threshold concentrations for gastrin I and CCK-OP were 2 X 10(-11) M and 4 x 10(-11) M, respectively. Unlike bethanechol, gastrin I (2 X 10(-9) M - 2 X 10(-8) M) and CCK-OP (4 X 10(-9) - 4 X 10(-8) M) altered slow-wave frequency and decreased slow-wave congruence. These studies suggest that 1) bethanechol, gastrin I, or CCK-OP increases colonic spike activity, and 2) only gastrin I or CCK-OP alters the slow-wave frequency of colonic muscle. Thus neurohumoral substances may act independently on colonic spike activity and colonic slow-wave frequency.

Abstract
Colonic myoelectric activity was determined using a mucosal clip electrode in normal human subjects, in the basal state and following the administration of prostigmin, pentagastrin, cholecystokinin, or secretin. Slow-wave activity was present 49 +/- 3.0% of the recording time and occurred at two frequencies, 6.5 +/- 0.1 cycles/min and 3.5 +/- 0.1 cycles/min, in the rectum. Spike potentials were infrequent in the basal state. Prostigmin, pentagastrin, or cholecystokinin did not affect the slow-wave activity or frequency, but these agents significantly increased the number of spike potentials (P less than 0.05). Secretin had no effect on myoelectric activity. The electrode system was tested in the cat and showed excellent correlation of the myoelectric activity between the mucosal clip electrode and a serosal electrode. These studies indicate: (1) a mucosal clip electrode provides an accurate method of recording colonic myoelectric activity when compared to a serosal electrode in the cat; (2) in man, slow-wave activity is present only intermittently and exists at two frequencies, approximately 6 cycles/min and 3 cycles/min; (3) gastrointestinal hormones and prostigmin increase spike potential discharge without altering slow-wave activity or frequency.

Abstract
The effect of intravenous infusion of gastrin II on gastric and colonic motor activity was studied in 12 patients; gastric acid output was also measured. Administration of gastrin at near-maximal dose levels stimulates the motor activity of the antrum but has no measurable effect on the activity of the proximal colon, sigmoid, or rectum. The results suggest that gastrin plays a part in the regulation of gastric motility but that it is not a mediator of the gastro-colic reflex.

Abstract
Both hog gastrin and synthetic gastrin stimulate the cardiac sphincter to increase tone and augment the resistance to reflux. Endogenous gastrin has a similar effect, and gastrin also stimulates the secretion of acid which has also been found to increase the resistance of the sphincter, but the effect of gastrin appears to be independent of the secretory stimulus.
