Expression of insulin-signaling

molecules Akt, PTEN, GSK3 beta, and eNOS receptors for short-chain fatty acids GPR41, and GPR43 as well as protein phosphatase PP2AA, PP2AB, PP2C were evaluated using Western blot analysis. Our results revealed that Akt2 knockout led to overt glucose intolerance, compromised cardiomyocyte GF120918 in vivo contractile function (reduced peak shortening and maximal velocity of shortening/relengthening as well as prolonged relengthening), loss of mitochondrial membrane potential, decreased GPR41 and elevated GPR43 expression, all of which, with the exception of glucose intolerance and elevated GPR43 level, were significantly attenuated by propionate. Neither Akt2 knockout nor propionate affected the expression of protein phosphatases, eNOS, pan, and phosphorylated PTEN and GSK3 beta. Conclusions. Taken together, these data depicted that Akt2 knockout may elicit cardiomyocyte contractile and mitochondrial defects and a beneficial role of propionate or short-chain fatty acids against Akt2 deficiency-induced cardiac anomalies.”
“Background and aims: NSC23766 order High blood pressure in subjects with the metabolic syndrome (MS) is largely related to dietary salt. We investigated in free-living men and women whether increase in dietary salt intake is associated

with the presence and severity of the MS.

Methods and results: A total of 766 subjects (251M, 515F) of 44.9 +/- 0.5 years/age and SBP/DBP of 120 +/- 0.6/77 +/- 0.4 mmHg were studied. Twenty-four hour urinary sodium (UNa+) and potassium (UK+) excretions were 143 +/- 2.5 mmot (median: 131.5) and 48 +/- 0.9 mmol (median: 44). UNa+ was higher in men than in women (median: 155.5 vs. 119.8 mmol/day; P < 0.0001). UK+ (r = 0.34; P < 0.0001), measures of obesity (r = 0.26; P < 0.0001) and BP (r = 0. 15; P < 0.0001) were significantly associated with UNa+. The association with BP was lost after adjusting for weight.

Of the 766 subjects, 256 (33.4%) met the NCEP-ATPIII criteria for the MS. Median UNa+ in men and women with no LY3023414 clinical trial traits of the MS was 140 and 116.7 mmol/day, respectively (P < 0.001), increasing

to 176 in men and 135 mmol/day in women with 4-5 components of the syndrome (P < 0.001). Weight, BMI and waist increased significantly across the quartiles of UNa+ both in men and women; whereas, age, lipids and fasting glucose did not. SBP and DBP were associated with UNa+ in men but not in women. UK+ correlated with age in men and women (r = 023; P < 0.0001) and with obesity in women (r = 0. 14; P = 0.001).

Conclusions: UNa(+)a measure of dietary sodium intake in free-living subjects was markedly increased in subjects with the MS. Higher UNa+ was associated with obesity and higher BP, but not with age, dyslipidemia or fasting glucose. (C) 2008 Elsevier B.V. All rights reserved.”
