NF-KappaB plays a critical role in the development of cancer. NF-kappaB is a transcription factor that promotes inflammation. This reveals the important relationship between inflammation and cancer.
inflammation plays critical role in insulin resistance and the associated inflammatory conditions. IKK-Beta and NF-KappaB are heavily involved in local and systemic inflammatory signaling.
It is proposed that the balance of bacteria in the gut play a critical role in energy utilization and obesity. This study showed that bypass surgery altered the gut bacteria to favor weight loss: decrease in firmicutes species. But, do we really need gastric bypass to do that? Of course not. Probiotics will do the same.
Study shows that gastrointestinal epithelial dysfunction is found in autism. This would play a critical role in systemic inflammation and would contribute to ASD symptoms through the gut-brain connection.
These observed changes, in correlation with a low T(3)/rT(3) ratio, may represent tissue-specific ways to reduce thyroid hormone bioactivity during cellular hypoxia and contribute to the low T(3) syndrome of severe illness.
Critically ill patients found to be depleted in glutathione, vitamin C, Zinc, and too a lesser extent: vitamin E. The obvious treatment would be to replace those identified deficiencies
Estrogen plays a critical role in the initiation of carcinogenesis of prostate cancer through the ER alpha/beta expression. As the authors state in their conclusion, "...ER alpha signaling potentiates the carcinogenic effects of androgens on the prostatic epithelium."
Peripheral 11Beta-HSD1 plays critical role in fat metabolism and energy utilization. Good discussion on the role that extra-adrenal 11Beta-HSD1 plays in metabolism
Study was undertaken in China due to alarming increase in breast cancer in Chinese women. This meta-analysis of 36 articles found a 44% increase in breast cancer with one abortion. This increased to 76% at 2 and 89% at 3 abortions respectively.
This study is very important and previous criticisms of prior studies linking abortion to breast cancer has been reporting bias. In China, due to the one child policy, abortion is a way of life and there is no cultural shame involved.
Stress decreases the innate immune response. This is critical in the battle against cancer. Specifically, low NK activity is found in stress individuals with cancer.
Normal leptin levels are critical to puberty; but in obese men, increased leptin is associated with gonadal decrease in Testosterone. It appears to occur through a decrease in 17-OH progesterone to Testosterone: suggesting an inhibitory activity in the conversion of 17-OH progesterone to Testosterone in obese men.
in addition to the type of diet being a modulator of microbiota composition, the timing of food intake plays a critical role in shaping intestinal microbial ecology.
the microbiota rhythms are influenced by the host clock and perform critical functions in the adaptation of metabolic processes to the diurnal fluctuations in the environment
Our study reveals that dysbiosis has a temporal dimension and that static microbiota comparisons might not be fully conclusive unless samples were taken in a controlled manner with respect to this important additional variable
This is a really nice study. Altered sleep-wake cycles result in altered food consumption which leads to altered gut microbiota diurnal oscillations. Gut microbiota have a normal diurnal oscillation. This altered gut flora then leads to increase insulin resistance, metabolic syndrome, diabetes...
A good biomarker of intracardiac TH signaling would be helpful but has not been identified. In the absence of such a marker,
a rational, cautious therapeutic approach might be to restore and maintain over time biochemical euthyroidism as documented
by normal circulating levels of TSH, FT4, and FT3.
a low-T3 state resulting from altered peripheral TH metabolism secondary to caloric restriction is associated
with impaired cardiac contractility
Low-T3 syndrome is the central finding and defines the illness in a variety of acute and chronic severe nonthyroidal illnesses
with cardiac origin, including MI, HF, and surgically treated cardiac disease.1 Low circulating levels of T3 in the absence of primary thyroid hypofunction have been found in 20% to 30% of patients with
dilated cardiomyopathy.
Great review of the current understanding of thyroid hormone metabolism in cardiac tissue. Low T3 and increased rT3 (via increased D3 activity) is CLEARLY associated with poor cardiac performance and post MI and CHF is associated with poor outcomes. T3 is critical in cardiac remodeling and recovery post MI. T3 is actually a vasodilatory in the coronary arteries. Why a endocrinologist would call rT3 useless only points to their ignorance of the literature.
