only abstract available here. Mouse model finds possible explanation for low Testosterone and diabetes link. Actually, the link is between the metabolite DHT and the AR. The activity of AR from DHT binding induces beta cell insulin secretion in the presence of glucose. This is dependent on glucagon-like peptide 1 receptor activation also, which AR activation by DHT does in fact do.
exercise found to improve central insulin and leptin resistance in obese animal model. The mechanism was via a decrease in inflammation through decrease in PTP1B protein transcription.
high fructose diet for just 9 weeks, > 60% liquid fructose, in rat model found to increase visceral adiposity, triglycerides, and lead to leptin resistance.
animal model finds that glutathione depletion increases hyperactivity of bronchioles. Early exposure to glutathione ethyl ester, a precursor to glutathione, blunted the airway hyperactivity.
In rat model, Estradiol shown to increase inflammation in lateral lobes of the prostate. Androgens, Testosterone > DHT, shown to inhibit this inflammatory response.
Fascinating article: DHEA found to decrease NF-KappaB activity in the hippocampus region of the brain. This has implications in protecting the brain. In this study, the implication was reduction in inflammation in the hippocampus region in diabetic rat model.
animal model: showed that DHEA treatment resulted in increased adiponectin secretion from fat cells. This occurred with an associated increase in PPAR-gamma receptors. The suggestion is that DHEA through PPAR-gamma increased fat cell production and secretion of adiponectin.
Now, this is in a rat TBI model; but progesterone was shown to reduce the inflammatory response post TBI. Particularily, through NF-kappa B inhibition.
SAMe increased hippocampal serotonin levels by 300% in rat brain model. Methylation is known to play a major role in serotonin, dopamine, and norepinephrine.
SAMe helps to correct disordered homocysteine metabolism due to B- vitamin deficiency found in Alzheimer's disease. SAMe show to reduce amyloid production, improve memory, decrease Tau, and reduced plaque formation. Now, this was in a mice model, but SAMe as a methyl donor can benefit clients with dementia with minimal side effects.
testosterone therapy in men with untreated prostate cancer was found to not be associated with cancer progression. These men were followed over an average 2.5 years. They concluded that, "these results are consistent with the saturation model i.e.. maximal prostate cancer growth is achieved at low androgen concentrations.
