When cerebrospinal fluid glucose was lowered by injecting pneumococcal neuraminidase intracisternally, no peripheral hyperinsulinemia resulted, indicating that increased spinal fluid insulin and its consequent increase of glucose uptake, rather than decreased spinal fluid glucose, is necessary to elicit the vagally mediated insulin secretion and hypoglycemia.

|
The more-cathodic intestinal ALP, which comigrated with ALP from colonic mucosa, was completely inhibited by levamisole and converted by neuraminidase to a species with a more basic pI than that of neuraminidase-digested tissue-nonspecific form.

Furthermore, liver binding data were not due to cross-reaction of 125I-labeled insulin to the insulinlike growth factor I receptor, and treatment of liver membranes with neuraminidase did not alter the inhibitory effect of the IgGa fraction from patient I-2 on 125I-labeled insulin binding to liver.
|
21 |
1727740
|
Binding inhibition experiments performed with cells transfected with and overexpressing the -12 (human insulin receptor [HIR]-A) or the +12 (HIR-B) variant of HIR revealed that the IgGa fraction from patient I-2 inhibited 125I-labeled insulin binding to the HIR-A receptor but not to the HIR-B receptor.

Serum very low molecular weight growth factor like-activity (S-VLMGA, molecular weight less than 3,000) and serum and urinary epidermal growth factor (S-, U-EGF) were investigated in 180 patients of non-insulin-dependent diabetes mellitus (NIDDM) by bioassay using skin fibroblast cells (CCD-27 SK) and enzyme- and radio-immunoassay, respectively.
|
23 |
2232255
|
S-VLMGA was slightly elevated in NIDDM patients with retinopathy (RET) and/or neuropathy (NEU), but slightly decreased in those with nephropathy (NEP) compared with patients without complications, though the differences were not significant (without complications: 122 +/- 9, with RET and/or NEU and without NEP: 145 +/- 15, all with NEP: 110 +/- 8% of increased growth activity, mean +/- SE).
|
24 |

However the changes in S-EGF were small and the decrease of U-EGF in patients with NEP was remarkable (U-EGF of without complications: 22.7 +/- 2.5, with RET and/or NEU and without NEP: 24.5 +/- 4.2, all with NEP: 17.6 +/- 3.2 ng/mg creatinine, mean +/- SE).

The role of membrane carbohydrate in the function of insulin receptors and glucose transporters was investigated with neuraminidase to release sialic acid from isolated rat adipocytes.
|
31 |
2666202
|
The enzyme action on glucose transport was not due to a nonspecific membrane perturbation because neuraminidase caused only a nonsignificant decrease in the uptake of the amino acid analog alpha-(methylamino)isobutyric acid and had no effect on basal or insulin-stimulated protein synthesis.
|
32 |
2666202
|
Insulin binding was slightly increased in neuraminidase-treated cells, yet the shapes of the dose-response curves for insulin stimulation of glucose transport were similar (EC50 = 0.087 +/- 0.010 and 0.082 +/- 0.008 nM for control and treated cells, respectively).

Five mutated genes on chromosome 20 have a relation to disease: a mutation in the adenosine deaminase gene results in a deficiency of the enzyme and severe combined immune deficiency; mutations in the gene for the growth hormone releasing factor result in some forms of dwarfism; mutations in the closely linked genes for the hormones arginine vasopressin and oxytocin and their neurophysins are probably responsible for some diabetes insipidus; and mutations in the gene that regulates both alpha-neuraminidase and beta-galactosidase activities determine galactosialidosis.

Rat PC12 pheochromocytoma cells synthesize insulin-like growth factor-binding protein-6.
|
69 |
7689963
|
Insulin-like growth factor-I (IGF-I) and IGF-II are mitogenic for PC12 cells under serum-starved conditions.
|
70 |
7689963
|
It recently was reported that PC12 cells produced an IGFBP that had a marked preferential binding affinity for IGF-II over IGF-I.
|
71 |
7689963
|
Rat IGFBP-6, like human IGFBP-6, is O-glycosylated; incubation with neuraminidase, fucosidase, and O-glycanase reduced its apparent molecular mass to 21 kilodaltons.
|
72 |
7689963
|
Competitive binding studies of rat and human IGFBP-6 with [125I]IGF-II and unlabeled IGF-II or IGF-I demonstrated that both IGFBPs bound IGF-II with similar affinities (Ka, 1.5-1.8 x 10(11) M-1) and bound IGF-I with approximately 25- to 35-fold lower affinity than IGF-II.

In the present study, we investigated the nature and the importance of glycosylation of two mammalian bombesin receptors, the neuromedin B receptor (NMB-R) and the gastrin-releasing peptide receptor (GRP-R), using chemical cross-linking and enzymatic deglycosylation. [125I]-(D-Tyr0)NMB cross-linked to native NMB-R on rat C-6 glioblastoma cells or rat NMB-R transfected into BALB 3T3 cells revealed a single broad band, M(r) = 63,000, on both cell types that was not altered by DTT.
|
74 |
7947701
|
NMB inhibited cross-linking specifically and saturably with an IC50 of 4.8 and 6.1 nM for C-6 and NMB-R transfected cells, respectively, and there was a close correlation between its ability to inhibit binding and its ability to inhibit cross-linking.
|
75 |
7947701
|
A single broad band of M(r) = 82,000 was cross-linked with [125I]GRP on mouse GRP-R transfected BALB 3T3 cells.
|
76 |
7947701
|
Peptide-N4-(N-acetyl-beta- glucosaminyl)asparagine amidase F (PNGase F) digestion increased the mobility of the original band in C-6, NMB-R, and GRP-R transfected cell membranes.
|
77 |
7947701
|
Neuraminidase digestion slightly increased the mobility of the original band in NMB-R transfected cell membranes; however, it had no effect on GRP-R transfected cell membranes.
|
78 |
7947701
|
Endo-alpha-N-acetylglucosaminidase (O-glycanase) digestion subsequent to neuraminidase treatment showed no additional effect on either receptor.
|
79 |
7947701
|
Treatment of unlabeled membranes with PNGase F followed by affinity labeling resulted in fully deglycosylated NMB-R or 75% deglycosylated GRP-R.
|
80 |
7947701
|
Deglycosylation of the NMB-R did not alter its affinity for NMB or alter G-protein coupling; however, 75% deglycosylation of the GRP-R both decreased its affinity for GRP and altered its ability to couple to G-proteins.

We found tryptase to be an inefficient activator of wild-type rat-PAR(2) (wt-rPAR(2)) and therefore decided to explore the factors that may influence tryptase activation of PAR(2). 2.
|
100 |
11606310
|
However, in the presence of either human-PAR(2) or wt-r PAR(2) expressing cells, tryptase could only activate PAR(2) by releasing SLIGRL from the P20 peptide, suggesting that PAR(2) expressed on the cells was protected from tryptase activation. 3.
|
101 |
11606310
|
Three approaches were employed to test the hypothesis that PAR(2) receptor glycosylation restricts tryptase activation.
|
102 |
11606310
|
(a) pretreatment of wt-rPAR(2) expressing cells or human embryonic kidney cells (HEK293) with vibrio cholerae neuraminidase to remove oligosaccharide sialic acid, unmasked tryptase-mediated PAR(2) activation.
|
103 |
11606310
|
(b) Inhibiting receptor glycosylation in HEK293 cells with tunicamycin enabled tryptase-mediated PAR(2) activation.
|
104 |
11606310
|
Immunocytochemistry using antisera that specifically recognized the N-terminal precleavage sequence of PAR(2) demonstrated that tryptase released the precleavage domain from PAR(2)T25(-) but not from wt-rPAR(2). 5.
|
105 |
11606310
|
Our results indicate that glycosylation of PAR(2) and heparin-inhibition of PAR(2) activation by tryptase could provide novel mechanisms for regulating receptor activation by tryptase and possibly other proteases.
