"randomly assigned 78 police officers to either the
experimental diet (carbohydrates at dinner) or a control weight loss diet

considered the hunger hormone, whose level in the blood is usually high during
the day and low during the night; and adiponectin, considered the link between

Dietary Resveratrol Has Differential Effects on Colorectal Tumorigenesis in
Adiponectin Knockout and Wild-Type Mice - Nutr Cancer. 2011 Sep 29 -
"Obesity is associated with a decrease in the
antiinflammatory hormone, adiponectin, and increases in the circulating
concentrations of multiple proinflammatory cytokines. These changes contribute
to colon tumorigenesis. Resveratrol increases adiponectin production in
adipocytes and attenuates the development of colon cancer. Thus, we hypothesized
that adiponectin is an integral component of the mechanism by which resveratrol
antagonizes colorectal tumorigenesis. To investigate this, we induced
tumorigenesis in adiponectin knockout (KO) and wild-type (Wt) C57BL/6 mice
through combined azoxymethane and dextran sodium sulfate treatment during which
mice were fed a high-fat, lard-based diet, or the same diet containing 20 mg/kg
resveratrol. After 14 wk on diet, Wt mice gained more weight and, on a
percentage basis, had higher fat mass and lower lean mass than KO mice.
Resveratrol tended to attenuate this response in male Wt mice. Resveratrol also
tended to reduce aberrant crypt foci development and decrease circulating
interleukin 6 and insulin concentrations in male but not female Wt mice. Taken
together, resveratrol improved overall health of obese Wt but not KO mice as
hypothesized with a differential sex response" - See

Isomer-specific effects of conjugated linoleic acid on blood pressure, adipocyte
size and function - Br J Nutr. 2011 Sep 23:1-9 -
"Consumption of conjugated linoleic acid (CLA) has been shown to modulate
cytokine release from adipocytes and positively influence blood pressure in
younger rats, but its physiological actions in older models with established
hypertension and isomer-specific effects on adipocyte size remain to be
determined. Therefore, we investigated the effects of CLA isomers on adipocyte
size in relation to blood pressure and adipokine production by hypertrophic
adipocytes in older fa/fa Zucker rats with established hypertension. fa/fa
Zucker rats were fed with cis(c)9, trans(t)11-CLA or t10, c12-CLA isomers for 8
weeks and compared with lean and obese rats fed with the control diet. Blood
pressure and adipocyte size were subsequently measured. Collagenase-isolated
adipocytes were size-separated and angiotensinogen and adiponectin protein
levels quantified by Western blotting. The t10, c12-CLA group had reduced blood
pressure, fewer large adipocytes and increased serum adiponectin.
Angiotensinogen was present at higher levels in the large adipocytes, whereas
the converse was observed for adiponectin. The beneficial effects of the t10,
c12-CLA isomer on blood pressure and adipocyte size in vivo may be due to its
ability to reduce the number of large adipocytes, which alters the levels of
vasoactive molecules secreted from adipose tissue" - See

"Conjugated linoleic acid (CLA) isomers have

according to Fischer-Posovszky, was that resveratrol reduced
production of certain cytokines (interleukins 6 and 8), substances
that may be linked to the development of obesity-related disorders,
such as diabetes and clogged coronary arteries. Also, resveratrol
stimulated formation of a protein known to decrease the risk of
heart attack. Obesity decreases this substance, called adiponectin"

Cardiol. 2013 Oct 3 - "Total and HMW adiponectin were
measured in 3,228 subjects without prevalent HF, atrial fibrillation or CVD. The
relations of total and HMW adiponectin with HF were nonlinear, with significant
associations observed only for concentrations greater than the median (12.4 and
6.2 mg/L, respectively). After adjustment for potential confounders, the hazard
ratios per SD increment in total adiponectin were 0.93 (95% confidence interval
0.72 to 1.21) for concentrations less than the median and 1.25 (95% confidence

"hidden" visceral fat found inside the body, between organs, in Asians and
probably other ethnic groups too, but not in whites. This in turn affects the
levels of adipokines secreted, such as leptin and adiponectin, which can have
adverse metabolic effects ... Overall, Japanese women had significantly lower
BMIs (23.7 vs 25.3 kg/m2), leptin (15.0 vs 25.9 ng/mL), and adiponectin (11.7 vs

Telmisartan reduced the extension of the infarct size in a dose-dependent
fashion and decreased the levels of plasma troponin I, a specific marker of
myocardial damage. Telmisartan also caused a dose-dependent increase in
adiponectin both in plasma and cardiac tissue of infarcted ZDF rats. These
levels were minimally increased (p<0.05 vs vehicle) by telmisartan 7 mg/kg/day
and reached the maximum values with the highest dose of 12 mg/kg/day (p<0.01 vs
vehicle). In contrast, within the infarcted tissue telmisartan decreased the
expression of markers of inflammation such as the transcription factor NF-κB,
the toll-like receptors TLR2 and TLR4 as well as TNF-α cytokine. Nitrosative
stress was maximal in vehicle-treated infarcted hearts as evidenced by increased
expression of iNOS, which was almost abolished after treatement with

known as the myocardium, to determine how the single hormone could exert such
different influences ... When the researchers introduced adiponectin into cells,

J Cancer. 2010 Dec 15;127(12):2758-67 - "Although
obesity is a risk factor for colorectal cancer, the underlying mechanism is not
clear. Adiponectin is an adipokine that binds to 2 types of receptors, AdipoR1
and AdipoR2. The plasma concentrations of adiponectin are reduced in obese
individuals and adiponectin has been reported to have anticarcinogenic
properties. Furthermore, AdipoR1 and AdipoR2 have been reported to be expressed
in several malignancies ... AdipoR1 and AdipoR2 immunostaining was detected in
72 and 68% of human colorectal cancer tissue, respectively. AdipoR1 and AdipoR2
expression levels were inversely related to T stage. The lowest AdipoR1 and
AdipoR2 expression were detected in poorly differentiated adenocarcinoma. RT-PCR
also showed the expression of AdipoR1 and AdipoR2 in HCT116 and SW620. MTT assay
and TUNEL assay demonstrated the tendency of growth inhibition and apoptosis
induction in both cell lines after full-length adiponectin treatment although
statistically insignificant. Microarray analysis revealed several gene responses
to full-length adiponectin, including upregulation of ENDOGL1 and MT1G. In
conclusion, AdipoR1 and AdipoR2 may be intimately related to the progression of

Hypoadiponectinemia is strongly associated with metabolic syndrome in korean
type 2 diabetes patients - J Am Coll Nutr. 2010 Jun;29(3):171-8 -
"Our findings show that hypoadiponectinemia is strongly
associated with MetS in type 2 DM patients. Dietary intake may be indirectly
associated with adiponectin levels through factors such as BMI, waist
circumference, insulin, homeostasis model assessment of insulin resistance
(HOMA-IR), triglyceride, HDL-cholesterol, and blood pressure. Therefore, our
results suggest that manipulation of the level of adiponectin may prevent MetS
and reduce the risk of cardiovascular disease in type 2 DM patients"
and Insulin Resistance Correlate with Telomere Length in Middle-aged Arabs: The
Influence of Circulating Adiponectin - Eur J Endocrinol. 2010 Aug -
"Studies in obesity have implicated adipocytokines in
the development of insulin resistance, which in turn may lead to accelerated
aging ... HOMA-IR was the most significant predictor for TL in males, explaining
35% of the variance (p = 0.01). In females, adiponectin, accounted for 28% of
the variance in TL (p = 0.01). Conclusion: Obesity and insulin resistance are
associated with chromosomal TL among adult Arabs. Evidence of causal relations
needs further investigation. The positive association of adiponectin to TL has
clinical implications as to the possible protective effects of this hormone from
accelerated aging" - Note: HOMA-IR = (glucose x insulin)/405 for glucose

Dietary Factors in Female Twins - J Nutr. 2008 Dec 23 -
"A significant relationship between adiponectin and 3
derived dietary patterns (F&V, dieting, traditional English), carbohydrate,
protein, trans fat, and alcohol intake was also observed. Strong inverse
associations with adiponectin were observed for BMI (-10.72%; 95% CI: -13.78,
-7.55), total (-6.89%: 95% CI: -10.34, -3.30; P < 0.05), and central fat mass

both when twins were analyzed as individuals and when characteristics were
contrasted within-twin pairs, suggesting a direct effect. We observed modest
associations between dietary factors and adiponectin in female twins,
independent of adiposity, and report strong inverse associations with body
composition. These data reinforce the importance of weight maintenance and

Dietary lipoic acid-dependent changes in the activity and mRNA levels of hepatic
lipogenic enzymes in rats - Br J Nutr. 2007 Dec 7;:1-9 -
"Lipoic acid profoundly decreased serum and liver
concentrations of TAG, and also lowered serum concentrations of phospholipid and
NEFA, and the concentration of cholesterol in the liver. A hypoglycaemic effect
of this compound was also observed. Lipoic acid dose-dependently decreased the
activity and mRNA levels of fatty acid synthase, ATP-citrate lyase, glucose
6-phosphate dehydrogenase, malic enzyme and pyruvate kinase in the liver despite
that reductions were considerably attenuated in the NADPH-producing enzymes.
This compound also dose-dependently lowered the mRNA levels of spot 14,
adiponutrin, stearoyl-CoA desaturase 1, and Delta5- and Delta6-desaturases. In
addition, lipoic acid dose-dependently lowered serum concentrations of insulin
and leptin, but increased those of adiponectin. Lipoic acid appeared to reduce
hepatic lipogenesis and hence decreases serum and liver lipid levels.
Alterations in serum concentrations of insulin and (or) adiponectin may trigger
this consequence" - See

Adiponectin, the controversial hormone - Public Health Nutr. 2007
Oct;10(10A):1145-50 - "Considering the anti-inflammatory
properties of adiponectin and the fact that it is negatively associated with
adiposity, this cytokine could be one of the links between obesity and
inflammation. The main mechanisms of action of adiponectin are directed to a
protective role against atherogenic and insulin resistance processes. Research
has revealed interesting new functions far beyond metabolism, such as immunity,
cancer and bone formation. Contrary to all adipose-related proteins, adiponectin
decreases with obesity. Most of the contradictory data surrounding adiponectin
