What is a sirtuin gene?

Sirtuins are a family of signaling proteins involved in metabolic regulation. The name Sir2 comes from the yeast gene ‘silent mating-type information regulation 2’, the gene responsible for cellular regulation in yeast.

What is the role of SIRT1?

Sirt1 serves as a deacetylase for numerous proteins involved in several cellular pathways, including stress response and apoptosis, and plays a protective role in neurodegenerative disorders, such as AD.

How does cancer affect gene expression?

Cancer can be described as a disease of altered gene expression. There are many proteins that are turned on or off (gene activation or gene silencing) that dramatically alter the overall activity of the cell. A gene that is not normally expressed in that cell can be switched on and expressed at high levels.

What are the 7 sirtuins?

These “sins” contribute to the seven deadly conditions that increase in prevalence with aging (obesity, type 2diabetes, cardiovascular disease, cancer, dementia, arthritis, and osteoporosis). The sirtuins are a class of NAD+-dependent deacetylases comprising seven members in humans and other mammals[1].

How can I boost my sirtuins?

The top foods high in sirtuin activators include:

1. kale.
2. parsley.
3. celery.
4. red wine.
5. strawberries.
6. onions.
7. dark chocolate (85% cocoa)
8. green tea.

How can I increase my SIRT1?

Levels of Sirt6 are increased upon nutrient deprivation in cultured cells. Sirt6, like Sirt1 levels, are also increased in the brain, kidney and heart of mice after a 24hr fasting period, and in white adipose tissue (WAT), heart and brain of rats fed a calorie-restricted diet for a minimum of one year (Kanfi, et al.

What foods are sirtuin activators?

Foods that contain sirtuin activators include: green tea, turmeric, onions, kale, parsley, miso soup, tofu and other soy products, olives and extra-virgin olive oil, blackcurrants, capers, cocoa, dates, walnuts and turmeric.

Is the Sirtfood diet healthy?

The Sirtfood Diet is unnecessarily restrictive and offers no clear, unique health benefits over any other type of diet. Furthermore, eating only 1,000 calories is typically not recommended without the supervision of a physician. Even eating 1,500 calories per day is excessively restrictive for many people.

What foods are high in NAD?

some varieties of fish like tuna, salmons and sardines are rich sources of NAD+ for the body. Mushrooms – many people like mushrooms and them as a regular food item in their regular diet. But did you know that mushrooms, especially the crimini mushrooms, also help in naturally boosting NAD levels?

What foods activate the skinny gene?

And, according to Aidan Goggins and Glen Matten, the authors of The Sirtfood Diet book, stocking up on sirtuin-rich foods such as kale, cocoa and parsley, can “stimulate the ‘skinny’ gene pathways and help you lose fat quickly”.

What foods increase sirtuins?

Are blueberries a SIRT food?

What are sirtfoods? Sirtfoods include blueberries, strawberries, dark chocolate and red wine as well as turmeric, parsley, onions, garlic and walnuts.

Why are Sirtuins important for the treatment of cancer?

Sirtuins are interesting drug targets due to the reported links of sirtuin activity to the pathogenesis of cancer, HIV, metabolic disorders, parasitic diseases (Lancelot et al., 2013 ), or neurodegeneration. Proof of cellular inhibition and especially selectivity in vivo has yet to be established for many sirtuin inhibitors.

What happens to the Sirtuin 1 gene after Docetaxel?

Altered Expression of CD44, SIRT1, CXCR4, miR-21, miR-34a, and miR-451 Genes in MKN-45 Cell Line After Docetaxel Treatment. Type 2 diabetes-associated polymorphisms correlate with SIRT1 and TGF-beta1 gene expression. Clinical significance of sirtuin 1 level in sepsis: correlation with disease risk, severity, and mortality risk.

How does the activation of sirtuin genes prolong life?

Studies show that the activation of sirtuin genes can prolong life. In countries like Japan and India, various Sirtfoods are part of the daily diet. Also known as ‘blue zones’, they have the lowest incidence of lifestyle associated diseases such as hypertension, obesity, diabetes, fatty liver and cancer.

What kind of cancer is caused by high SIRT1?

However, some other studies show that sirtuins may in fact be a contributor to the development of cancer. High SIRT1 expression was observed in a variety of cancers, including colon carcinomas, prostate cancers, and acute myeloid leukemia.
