Describe the biological mechanism of resveratrol extracted from mulberry. in delaying aging and preventing cancer
in mulberry (Especially in the peel) contains an important substance called Resveratrol, a type of polyphenol that has been widely studied for its anti-aging and anti-cancer properties. The biological mechanism of resveratrol is quite complex and involves several mechanisms:
Resveratrol's anti-aging mechanism:
Activation of Sirtuins protein (SIRT1):
Resveratrol is famous for being an activator of sirtuins, especially SIRT1 (Sirtuin 1), a protein that plays a key role in regulating many biological processes involved in delaying aging.
SIRT1's duties:
DNA Repair: SIRT1 helps in repairing DNA damage, which is a major cause of aging.
Gene Expression Regulation: SIRT1 can deacetylate many histones and non-histone proteins, resulting in changes in the expression of genes involved in energy metabolism. stress resistance and cell survival
Reducing inflammation: SIRT1 can inhibit the transcription factor NF-κB (Nuclear Factor-kappa B), a key mediator in chronic inflammatory responses. Chronic inflammation is one of the leading causes of aging and age-related diseases.
Mitochondrial enhancement: SIRT1 increases mitochondrial biogenesis and improves mitochondrial function. which is the source of cellular energy production Reduced mitochondrial function is a key feature of aging.
Autophagy regulation: SIRT1 promotes autophagy, a mechanism by which cells remove damaged or unnecessary components. Helps maintain cell health
Balancing AMPK (AMP-activated protein kinase):
Resveratrol can stimulate AMPK, a key enzyme that controls cellular energy metabolism.
The function of AMPK: Activating AMPK mimics the effects of caloric restriction, a method that has been shown to extend lifespan in many organisms. AMPK promotes catabolism and inhibits anabolism, such as the synthesis of fats and proteins. This puts the cell in a state of saving energy and repairing itself.
Antioxidant Activity:
Resveratrol is a powerful antioxidant. Can eliminate free radicals that are harmful to cells, such as Reactive Oxygen Species (ROS), which are important causes of cell damage and accelerate the aging process.
It can also increase levels of endogenous antioxidant enzymes such as glutathione peroxidase (GPx), superoxide dismutase (SOD), and catalase.
Inhibition of inflammation (Anti-inflammatory Activity):
In addition to inhibiting NF-κB, resveratrol can also inhibit inflammation-related enzymes such as cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS). Reducing chronic inflammation slows the deterioration of tissues and organs.
Resveratrol's protective and anti-cancer mechanism:
Resveratrol exhibits protective and anti-cancer properties at various stages of cancer progression. (carcinogenesis) from initial stages to metastasis:
Inhibiting the initiation of cancer (Cancer Initiation):
Antioxidants: Reduces DNA damage from carcinogens and free radicals.
Inhibition of Phase I Enzymes: Resveratrol can inhibit Phase I enzymes (such as cytochrome P450 enzymes) that activate certain carcinogens.
Inhibiting the promotion of cancer growth (Cancer Promotion):
Inhibition of inflammation: Reduces chronic inflammation, which is a factor promoting the growth of cancer cells.
COX-2 inhibition: Reduces prostaglandin production. that promotes the growth of cancer cells and the creation of new blood vessels
Inhibition of cancer progression (Cancer Progression):
Apoptosis Induction: Resveratrol can induce cancer cells to undergo apoptosis (programmed cell death), which is an important mechanism for eliminating abnormal cells from the body. This mechanism involves regulation of the p53 pathway and activation of caspases.
Cell Proliferation Inhibition: Resveratrol can stop cell cycle arrest in cancer cells. This causes cancer cells to be unable to divide and multiply.
Inhibition of new blood vessel formation Angiogenesis Inhibition: The creation of new blood vessels is necessary for cancer cells to grow and spread. Resveratrol can inhibit new blood vessel formation by reducing the expression of vascular growth factors such as VEGF (Vascular Endothelial Growth Factor).
Metastasis Inhibition: Resveratrol can inhibit the movement and invasion of cancer cells. Including reducing the expression of enzymes involved in tissue degradation, such as matrix metalloproteinases (MMPs).
Summary:
Resveratrol extracted from mulberry shows anti-aging and anti-cancer potential through diverse and complex biological mechanisms. In particular, SIRT1 protein activation, AMPK balance modulation, antioxidant effect, inflammation inhibition, apoptosis induction in cancer cells, cell proliferation inhibition, angiogenesis inhibition. and inhibiting the spread of cancer
