A role of thyrotropin-releasing hormone in insulin secretion by isolated rat pancreatic islets
Abstract Insulin-secreting pancreatic β cells also express thyrotropin-releasing hormone (TRH). Although the physiological role of TRH in this localization is unclear, its participation in glucoregulation has been implied. To test this hypothesis, we blocked the last step of post-translational matur...

| 520 | |a Abstract Insulin-secreting pancreatic β cells also express thyrotropin-releasing hormone (TRH). Although the physiological role of TRH in this localization is unclear, its participation in glucoregulation has been implied. To test this hypothesis, we blocked the last step of post-translational maturation of the TRH molecule by disulfiram, which is an active inhibitor of peptide α-amidation (PAM) within pancreatic islet cells. The treatment of male rats with 200 mg/kg/day of disulfiram during a 5-day period resulted in a low PAM activity, a high insulin content and its basal secretion from pancreatic islets, and the inability to release insulin in response to glucose (16.7 mM) or hypo-osmotic (30%) challenge in vitro. The addition of TRH (1 nM) to the medium during incubation restored the insulin content and both basal and glucose stimulated insulin secretions to control levels. Conclusion: TRH plays an important role in the mechanism of insulin secretion and its response to glucose stimulation. | ||

Although the physiological role of TRH in this localization is unclear, its participation in glucoregulation has been implied. To test this hypothesis, we blocked the last step of post-translational maturation of the TRH molecule by disulfiram, which is an active inhibitor of peptide α-amidation (PAM) within pancreatic islet cells. The treatment of male rats with 200 mg/kg/day of disulfiram during a 5-day period resulted in a low PAM activity, a high insulin content and its basal secretion from pancreatic islets, and the inability to release insulin in response to glucose (16.7 mM) or hypo-osmotic (30%) challenge in vitro. The addition of TRH (1 nM) to the medium during incubation restored the insulin content and both basal and glucose stimulated insulin secretions to control levels.

Although the physiological role of TRH in this localization is unclear, its participation in glucoregulation has been implied. To test this hypothesis, we blocked the last step of post-translational maturation of the TRH molecule by disulfiram, which is an active inhibitor of peptide α-amidation (PAM) within pancreatic islet cells. The treatment of male rats with 200 mg/kg/day of disulfiram during a 5-day period resulted in a low PAM activity, a high insulin content and its basal secretion from pancreatic islets, and the inability to release insulin in response to glucose (16.7 mM) or hypo-osmotic (30%) challenge in vitro. The addition of TRH (1 nM) to the medium during incubation restored the insulin content and both basal and glucose stimulated insulin secretions to control levels. Conclusion: TRH plays an important role in the mechanism of insulin secretion and its response to glucose stimulation.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Cell swelling</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Glucose</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Insulin</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Pancreatic islets</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Rat</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">TRH</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Bačová, Zuzana</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Mátéffyová, Adela</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Štrbák, Vladimír</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Pflügers Archiv</subfield><subfield code="d">Berlin : Springer, 1868</subfield><subfield code="g">449(2004), 6 vom: 16.

A role of thyrotropin-releasing hormone in insulin secretion by isolated rat pancreatic islets |
| abstract |
Abstract Insulin-secreting pancreatic β cells also express thyrotropin-releasing hormone (TRH). Although the physiological role of TRH in this localization is unclear, its participation in glucoregulation has been implied. To test this hypothesis, we blocked the last step of post-translational maturation of the TRH molecule by disulfiram, which is an active inhibitor of peptide α-amidation (PAM) within pancreatic islet cells. The treatment of male rats with 200 mg/kg/day of disulfiram during a 5-day period resulted in a low PAM activity, a high insulin content and its basal secretion from pancreatic islets, and the inability to release insulin in response to glucose (16.7 mM) or hypo-osmotic (30%) challenge in vitro. The addition of TRH (1 nM) to the medium during incubation restored the insulin content and both basal and glucose stimulated insulin secretions to control levels. Conclusion: TRH plays an important role in the mechanism of insulin secretion and its response to glucose stimulation. |
