|
Sodium and fluid retention is a well documented phenomenon in insulin-dependent diabetes mellitus (IDDM), but it is not known whether diabetes-associated alterations in cortisol metabolism contribute to its pathogenesis.
|

|
In seven microalbuminuric IDDM patients, the angiotensin-converting enzyme inhibitor, enalapril (10 mg daily for 6-12 weeks), resulted in a moderate further lowering of the cortisol to cortisone metabolite ratio (P < 0.05).

Adult offspring of CBX-treated dams had persistently reduced body weight, increased basal corticosterone (CORT) levels, increased corticotropin-releasing hormone (CRH) and reduced glucocorticoid receptor (GR) mRNA in the hypothalamic paraventricular nucleus, though hippocampal GR and mineralocorticoid receptor (MR) mRNA expression were unaltered.
|
28 |
11311532
|
Adult DEX3 offspring also showed increased corticotrophin-releasing hormone mRNA with unaltered glucocorticoid receptor mRNA in the hypothalamic paraventricular nucleus and reduced hippocampal glucocorticoid- and mineralocorticoid receptor mRNA expression, suggesting reduced hippocampal sensitivity to glucocorticoid suppression of the stress axis.
|

Hyperactivation of the HPA axis in diabetes is associated with increased expression of hypothalamic corticotrophin-releasing hormone (CRH) mRNA and hippocampal mineralocorticoid receptor (MR) mRNA.
|
30 |
12717340

We have recently shown that mineralocorticoid receptor blockade may represent optimal therapy for patients with early diabetic nephropathy who show aldosterone breakthrough during angiotensin-converting enzyme (ACE) inhibitor treatment, and who no longer show the maximal antiproteinuric effects of ACE inhibition.
|
41 |

Basal: Elevated basal ACTH and corticosterone in STZ rats were normalized with insulin but not phloridzin.
|
45 |
15774766
|
Increases in hypothalamic corticotrophin-releasing hormone (CRH) and inhibitory hippocampal mineralocorticoid receptor (MR) mRNA with STZ diabetes were not restored with either insulin or phloridzin treatments.
|
46 |
15774766

Insulin and phloridzin restored both ACTH and corticosterone responses in diabetic animals.
|
47 |
15774766
|
Hypothalamic CRH mRNA and pituitary pro-opiomelanocortin mRNA expression increased following 2 h of hypoglycemia in normal, insulin-treated, and phloridzin-treated diabetic rats but not in untreated diabetic rats.
|
48 |
15774766
|
Interestingly, hypoglycemia decreased hippocampal MR mRNA in control, insulin-, and phloridzin-treated diabetic rats but not uncontrolled diabetic rats, whereas glucocorticoid receptor mRNA was not altered by hypoglycemia.

Aldosterone increases urine production and decreases apical AQP2 expression in rats with diabetes insipidus.
|
50 |
16159898
|
We investigated the effects of 7-day aldosterone infusion or oral spironolactone treatment on water balance and aquaporin (AQP) 2 expression in rats with 21 days of lithium-induced nephrogenic diabetes insipidus (Li-NDI).
|
51 |
16159898
|
Semiquantitative confocal immunofluorescence microscopy of AQP2 immunolabeling showed reduced AQP2 expression in the apical plasma membrane domain in connecting tubule (CNT) and initial cortical collecting ducts (iCCD) in response to aldosterone-treated rats compared with rats treated with lithium only.
|
52 |
16159898
|
Spironolactone significantly increased apical AQP2 expression in the iCCD compared with rats treated with lithium only.
|
53 |
16159898
|
We also tested whether similar changes could be observed in vasopressin-deficient BB rats and found similar changes in urine production and subcellular AQP2 expression in the CNT and iCCD in response to aldosterone and spironolactone.
|
54 |
16159898
|
This study shows that aldosterone treatment perturbs diabetes insipidus and is associated with AQP2 redistribution in CNT and iCCD likely mediated by the spironolactone-sensitive mineralocorticoid receptor.
|
55 |
16174286
|
We investigated the effect of aldosterone and spironolactone, which is a non-selective mineralocorticoid receptor antagonist, on monocyte chemoattractant peptide (MCP-1) and collagen synthesis in cultured mesangial and tubular epithelial cells.

56 |
16174286
|
However, spironolactone therapy significantly inhibited urinary albumin and MCP-1 excretion.
|
57 |
16174286

Spironolactone treatment also suppressed renal mRNA expression for MCP-1, macrophage migration inhibitory factor (MIF) as well as intrarenal protein synthesis for ED-1 and MIF.
|
58 |
16174286
|
Morphologically, spironolactone treatment significantly prevented glomerulosclerosis, collagen deposition and connective tissue growth factor (CTGF) expression in diabetic rats.
|
59 |
16174286
|
In cultured cell experiments, aldosterone directly increased the MCP-1, collagen secretion and spironolactone treatment abolished aldosterone-induced MCP-1 and collagen synthesis.
|
60 |
16174286
|
In addition, prior treatment with pyrrolidine dithiocarbamate (PDTC), which is a NF-KB inhibitor, inhibited aldosterone-induced MCP-1 protein secretion.

The aim of this study was to investigate a series of single-nucleotide polymorphisms (SNPs) in the genes MC2R, MC3R, MC4R, MC5R, POMC, and ENPP1 for association with obesity.
|
68 |
18551113
|
Weaker associations were detected between the SNPs rs1541276 in the MC5R, rs1926065 in the MC3R genes and obesity (P = 0.04 and P = 0.03, respectively), and between SNPs rs2236700 in the MC5R, rs2118404 in the POMC, rs943003 in the ENPP1 genes and type 2 diabetes (P = 0.03, P = 0.02 and P = 0.02, respectively); these associations did not, however, remain significant after correction for multiple testing.

20363891
|
Endothelial caveolin-1 (cav-1) is an anchoring protein in plasma membrane caveolae where it binds endothelial nitric oxide synthase (eNOS) and limits its activation, particularly in animals fed a high salt (HS) diet.
|
91 |
20363891
|
Cav-1 also interacts with steroid receptors such as the mineralocorticoid receptor (MR).
|
92 |
20363891
|
Thus in cav-1 deficiency states and HS diet MR blockade is associated with increased BP, enhanced vasoconstriction, and decreased NOS-mediated vascular relaxation and eNOS expression.

Key components of the metabolic syndrome (MetS), ie, obesity and insulin resistance, are associated with increased aldosterone production and mineralocorticoid receptor (MR) activation.
|
99 |
20697411
|
In this setting, activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS), as well as increased signaling through the mineralocorticoid receptor (MR), result in increased production of reactive oxygen species and oxidative stress, which in turn contribute to insulin resistance and impaired vascular function.

It is likely that life-style modification, visceral fat reduction and use of medications that increase serum adiponectin levels (e.g., rimonabant, thiazolidinediones, fibrates, angiotensin receptor blocker and mineralocorticoid receptor blockade) when provided in combination can improve hypoadiponectinemia and thus prevent the development of life style-related diseases including T2DM and ACVD.

|
To optimize the degree of blockade of renin-angiotensin-aldosterone system, dose uptitrations of angiotensin-converting enzyme inhibitors and angiotensin receptor antagonists or the use of a dual blockade, initially identified with the combination of angiotensin-converting enzyme inhibitors and angiotensin receptor antagonists, have been proposed.

However, the dual blockade of angiotensin-converting enzyme inhibitors/angiotensin receptor antagonists with direct renin inhibitors is currently under investigation while that based on an aldosterone blocker with any of the previous three drugs requires more evidence beyond heart failure.

In vertebrates, the transcription factor ChREBP is a major component in glucose metabolism, while its ortholog MondoA is involved in glucose uptake.
|
125 |
22506051
|
Both MondoA and ChREBP contain five Mondo conserved regions (MCRI-V) that affect their cellular localization and transactivation ability.
|
126 |
22506051
|
While phosphorylation has been shown to affect ChREBP function, the mechanisms controlling glucose response of both ChREBP and MondoA remain elusive.
|
127 |
22506051
|
By incorporating sequence analysis techniques, structure predictions, and functional annotations, we synthesized data surrounding Mondo family proteins into a cohesive, accurate, and general model involving the MCRs and two additional domains that determine ChREBP and MondoA glucose response.
|
128 |

|
These interactions are likely involved in altering ChREBP and MondoA conformation to form an active complex and induce transcription of genes involved in glucose metabolism and lipogenesis.
