Activation of the SIRT1 (Sirtuin 1) gene plays an important role in the anti-aging process and prevention of chronic non-communicable diseases (NCDs) including cancer. It involves the process of stimulating the creation of new mitochondria. Mitochondrial biogenesis is the heart of cellular energy and overall cellular health.

Biological mechanism of SIRT1 and mitochondrial formation and effects on aging

1. What is SIRT1?

SIRT1 is one of the sirtuin genes (SIRT1–SIRT7) which functions as NAD⁺-dependent deacetylase — Proteins that require NAD⁺ to "remove" acetyl groups from target proteins. causing effects on the function of that protein, with SIRT1 being the one that has been most widely studied and is directly related to slowing down aging and responding to stress. and cell metabolism

2. How does SIRT1 activation affect mitochondria?

When SIRT1 is stimulated (e.g. by resveratrol, calorie restriction or fasting):

SIRT1 deacetylates (removes the acetyl group) from PGC-1α (Peroxisome proliferator-activated receptor gamma coactivator 1-alpha).

As a result, PGC-1α is activated. and stimulate genes related to Creating new mitochondria (mitochondrial biogenesis) and increasing the efficiency of energy metabolism

Summary in order:

1. SIRT1 activation

2. SIRT1 deacetylates PGC-1α.

3. PGC-1α stimulates the expression of mitochondrial-related genes.

4. Increase the number and quality of mitochondria in cells.

5. Increase energy generation efficiency Reduce free radicals

6. Effects on slowing down aging and preventing chronic diseases.

Relationship with anti-aging and NCDs

1. Delay aging

Mitochondrial deterioration is one of the leading causes of aging.

SIRT1 helps prevent the accumulation of free radicals (ROS), reducing oxidative stress.

Promotes recycling of old organelles (autophagy), which slows down cell degeneration.

2. Chronic non-communicable diseases (NCDs)

Type 2 diabetes: SIRT1 improves insulin sensitivity. and reduces blood glucose levels

Cardiovascular disease: reduces inflammation in blood vessels Activate eNOS → increase NO → dilate blood vessels

Alzheimer's/Parkinson's: SIRT1 reduces neuronal death. and promote brain cell function

3. Cancer

SIRT1 has complex roles. But in the context of Cancer prevention:

Helps repair damaged DNA

Reduce gene mutations

Stimulates the apoptosis process of abnormal cells.

Summary:

SIRT1 activation is directly linked to Creating new mitochondria Through the stimulation of PGC-1α, cells have higher energy levels. Reduce oxidative stress and make the process of slowing aging actually happen, including being able to systematically reduce the risk of NCDs and cancer.
