Rats with hereditary hypothalamic diabetes insipidus (homozygotes of Bratteboro strain) were found to have significantly lower renal medullary adenylate cyclase activity, either basal activity or activity stimulated by vasopressin, as compared with controls (heterozygotes of the same strain).

The treatment of rats with hereditary hypothalamic diabetes insipidus with exogenous vasopressin increased the activity of renal medullary adenylate cyclase stimulated in vitro by maximal doses of vasopressin, but had no effect on the basal activity of adenylate cyclase or on the activity of cyclic AMP phosphodiesterase.

Parathyroid hormone (PTH) stimulates adenylate cyclase predominantly in the renal cortex, whereas vasopressin (ADH) stimulated the enzyme in the medulla; thus PTH and ADH could increase the amount of cAMP in the urine from the renal source.

It is suggested that somatostatin suppresses cyclic AMP excretion by inhibiting directly adenylate cyclase in liver and perhaps in other organs.

In the high-dose insulin-treated diabetic rats, glucagon binding and basal and glucagon-stimulated adenylate cyclase activity were normalized to control values, whereas low-dose insulin treatment resulted in changes intermediate between control and untreated diabetic rats.

These studies were performed with a clonal cell line of glucose-responsive beta-cells (HIT cells) to determine whether PGE2 effects on insulin secretion are receptor mediated and, if so, whether the postreceptor effects are mediated by inhibitory regulatory components (Ni) of adenylate cyclase.

The GIP binding sites of human insulinoma were coupled to adenylate cyclase stimulation.

Preincubation with pertussis toxin or with manganese completely abolished the inhibitory effect of the peptides, suggesting that this is mediated by an inhibitory adenylate cyclase regulatory protein. sCT, hCT, and CGRP each showed unique patterns with regard to time course of inhibition of cAMP accumulation.

Forskolin and four analogues of forskolin, 7-beta-[gamma-(N'-methylpiperazino)-butyryloxy]-7-desacet ylforskolin, 7-desacetylforskolin, 7-tosyl-7-desacetylforskolin, and 1,9-dideoxyforskolin, were tested for their ability to activate adenylate cyclase, inhibit glucose transport, and inhibit cytochalasin B binding in rat adipocyte membranes.

These results suggest that insulin secretion of non-insulin-dependent diabetes mellitus (NIDDM) rat model is selectively impaired in response to glucose stimulation, possibly due to a disorder of signaling mechanism other than adenylate cyclase.

Adenylate cyclase activity and its modulation by guanine nucleotides and isoproterenol were assessed in adipocyte membranes of mice with mutations causing different genetic obesity syndromes.

|
However, the parathyroid hormone (PTH) sensitive renal adenylate cyclase activity of diabetic rats was not different from that of the nondiabetic rats in either the vitamin D replete group or the vitamin D depleted group.

|
On the other hand, the PTH-sensitive renal adenylate cyclase activity was significantly higher in short-term diabetic rats than in control and insulin-treated rats.

Angiotensin II inhibition of hepatic adenylate cyclase was not altered in either diabetic rat.

Cholecystokinin (CCK) and acetylcholine activate the hydrolysis of polyphosphoinositides, and gastric inhibitory polypeptide (GIP) and glucagonlike peptide 1 activate adenylate cyclase.

|
In addition, isoproterenol, guanosine 5'-triphosphate (GTP), and NaF were unable to stimulate adenylate cyclase activity.

|
The effects of the diabetic state on adenylate cyclase and surfactant secretion were reversed by in vivo but not in vitro insulin treatment.

Adenylate cyclase activity was examined as a measure of inhibitory guanine nucleotide binding protein (Gi) function in liver plasma membranes from rats made chemically diabetic by streptozotocin (STZ) treatment.

In 293 cells, human TSH beta gene expression was not stimulated by the adenylate cyclase activator forskolin or the cAMP analogue 8-bromo-cAMP (8-Br-cAMP).

Conversely, CGRP as well as IAPP-NH2 but not IAPP-COOH evoked dose-dependent activation of adenylate cyclase in the membranes, and these effects were significantly inhibited by a CGRP receptor antagonist, human CGRP-I(8-37).
|

|
Human CGRP I and cCGRP at 2.5 microM did not stimulate the activity of hamster insulinoma cell membranes adenylate cyclase, while glucagon (1 microM) induced a 2-fold increase.
|

|
These results and the observation that cCGRP and hCGRP I did not influence adenylate cyclase activity provide further evidence for CGRP receptor subtypes.

For each splice variant, PACAP (both PACAP-38 and PACAP-27) had similar affinity and potency for stimulating either adenylate cyclase or phospholipase C.

From binding studies of their abilities to directly interact with hVPAC1 (T47D cells, hVPAC1-transfected cells) and hVPAC2 (Sup T1- and VPAC2-transfected cells) and to stimulate adenylate cyclase in each, two analogs [(Ala(2,8,9,11,19,22,24,25,27,28))VIP and (Ala(2,8,9,11,19,24-28))VIP] were found to have >2000- and >600-fold selectivity for hVPAC1.

Moreover, pretreatment with inhibitors of iNOS and guanylate cyclase, but not an adenylate cyclase inhibitor, abolished TNF-alpha-induced lipolysis and HSL phosphorylation.

In summary, GSK3beta inactivation or deletion reduces aquaporin 2 expression by modulating adenylate cyclase activity and cAMP generation, thereby impairing responses to vasopressin in the renal collecting duct.

Ghrelin suppressed glucose (8.3 mmol/L)-induced insulin release in rat perfused pancreas and isolated islets, and these effects of ghrelin were blunted in the presence of cAMP analogs or adenylate cyclase inhibitor.
