GPI — INS
Text-mined interactions from Literome
Müller et al., Biochemistry 2000
:
GPI-PLC was most pronouncedly
stimulated by authentic human
insulin compared to various insulin analogues and insulin-like growth factor I
Müller et al., Biochem Pharmacol 2005
:
In contrast, blockade of the moderate
insulin activation of the
GPI-PLC and of lipid raft protein redistribution by GPI-2350 slightly reduced insulin signalling and metabolic action, only
Wood et al., J Endocrinol 1992
:
pH(i) in the
presence of both TSH and
insulin was 7.81 +/- 0.03 ( n = 60 )
Gunawardana et al., BMC endocrine disorders 2005
:
Nutrient stimulated
insulin secretion ( NSIS )
requires a specific
pHi-range , and is dramatically enhanced by forced intracellular acidification with DMA
Yoon et al., Arch Pharm Res 2007
:
Taken together, these results suggest that
insulin , in part, may
activate a
GPI-PLC , via PI-PLC/intracellular Ca2+, which may consequently stimulate the release of RDPase
Axelrod et al., Diabetes 1991
(Hyperinsulinism...) :
Thus,
insulin may
regulate PGI2 and PGE2 production by adipose tissue ( and possibly other tissues ) through a wide range of concentrations with important physiological and clinical consequences
Rosenthal et al., J Surg Res 1990
:
The results of these experiments indicate that human
insulin inhibits both basal and arachidonic acid stimulated production of
PGI2 from HUVEC in a dose dependent manner ... We therefore conclude that
insulin , in locally high concentrations,
inhibits endothelial
PGI2 production in vitro
Axelrod et al., Endocrinology 1986
:
Insulin selectively
inhibited isoproterenol stimulated
PGI2 production and triglyceride lipolysis at physiological concentrations, but had no effect on angiotensin II-stimulated PGI2 production ... We conclude that : angiotensin II stimulates PGI2 production rapidly and independently of cAMP, but isoproterenol stimulates
PGI2 production more slowly, an effect that is cAMP dependent ;
insulin inhibits the cAMP dependent beta-adrenergic stimulation of PGI2 production ( and triglyceride lipolysis ), but not the cAMP independent angiotensin II-induced stimulation of PGI2 production ( this suggests that the former effect is mediated by a decrease in cAMP levels in the adipocyte ) ; and dexamethasone inhibits both mechanisms of PGI2 production
Ahrén et al., Peptides 1989
:
Since VIP and
PHI both
stimulate insulin and glucagon secretion, we investigated the effects of helodermin on insulin and glucagon secretion in the mouse, both in the basal state and during administration of glucose and the cholinergic agonist carbachol
Ahrén et al., Neuropeptides 1988
:
It was found that
PHI did not
affect basal levels of
insulin of glucagon ... When injected together with glucose ( 2.8 nmol/kg ),
PHI ( 1.0 and 4.0 nmol/kg )
potentiated the
insulin response by approximately 35 % ( P less than 0.05 ) and 50 % ( P less than 0.01 ), respectively ... In contrast, the
insulin response to the cholinergic agonist carbachol ( 0.16 mumol/kg ) or the beta 2-adrenoceptor agonist terbutaline ( 3.6 mumol/kg ) was not
affected by
PHI
Cook et al., J Biol Chem 1988
(Liver Neoplasms, Experimental) :
Insulin and serum, alone or in combination, did not
cause pHi to increase in either 4- ( 2-hydroxyethyl ) -1-piperazineethanesulfonic acid ( HEPES ) ( pHi 7.17 ) - or HCO3/CO2 ( pHi 7.19 ) - buffered media
Yanaihara et al., Peptides 1986
:
Replacement of amino-terminal decapeptide portion of the PHI molecule with the corresponding part of VIP resulted in a drastic decrease of the potentiating
effect of
PHI on
insulin release
Stith et al., Dev Biol 1985
:
Sodium-free medium decreased basal pHi by 0.3 unit and prevented increases in
pHi in
response to both
insulin and progesterone, but S6 phosphorylation occurred normally with both hormones
Szczeklik et al., Prostaglandins 1980
(Arteriosclerosis...) :
PGI2 repressed glucose induced
insulin release in some normoglycemic patients but in others it either increased it or did not affect it
Szecówka et al., Am J Physiol 1983
:
PHI increased the release of
insulin , glucagon, and somatostatin ... In the presence of 16.7 mmol/liter glucose, only
insulin secretion was
increased by
PHI ... When arginine was used as a secretagogue,
PHI ( 10 nmol/liter )
potentiated secretion of
insulin , glucagon, and somatostatin
Lasché et al., Diabetes 1982
:
Suppression of
insulin production in
presence of
PGI2 in high glucose medium resembles the action of other prostaglandins and suggests it may inhibit insulin secretion after a glucose load
Patrono et al., Prostaglandins 1981
:
Thus, in contrast to PGE2,
PGI2 does not
affect insulin secretion nor glucose disposal at doses producing platelet and vascular changes
Fidelman et al., Am J Physiol 1982
:
The results support the model that the acute effect of
insulin on glycolysis is
mediated by a change in
pHi , consequent to activation by insulin of Na : H exchange at the plasma membrane
Morris et al., J Biol Chem 1995
:
Glucosaminyl ( alpha 1 -- > 6 ) -D-myo-inositol ( GlcN ( alpha 1 -- > 6 ) Ins ), GlcN ( alpha 1 -- > 6 ) Ins 1,2-cyclic phosphate, GlcN ( alpha 1 -- > 6 )
-2-deoxy-Ins , and GlcN ( alpha 1 -- > 6 ) Ins 1-dodecyl phosphonate
inhibited GPI-PLC
Müller et al., J Cell Biol 1994
:
Inhibition of glucose transport or incubation of rat adipocytes in glucose-free medium completely abolished
stimulation of
GPI-PL by either
insulin or glimepiride
Takahashi et al., Hypertens Res 1996
:
The
insulin induced
pHi increase was almost completely inhibited by 10 ( -3 ) mol/l amiloride in the lumen, indicating that insulin activates luminal Na/H exchange in PST
