Overview of Sirtuins

Sirtuins act as tiny cellular switches that control many vital body functions and play a role in aging and age-related diseases. These proteins need NAD to work, and they help your cells stay healthy through key tasks like fixing DNA and managing stress.

1.     Structure and classification of sirtuins

Your body has seven different sirtuins that work in specific places. SIRT1, SIRT6, and SIRT7 stay in the cell nucleus. SIRT2 lives in the cell fluid. SIRT3, SIRT4, and SIRT5 work inside tiny cell parts called mitochondria.

Each sirtuin has a special job — SIRT4 breaks down fat molecules instead of removing acetyl groups like other sirtuins do.

Scientists group these proteins into four main types (I-IV) based on their building blocks. These proteins belong to a special group called Class III histone deacetylases. The NAD+ molecule helps them work properly.

Your body changes how active these proteins are based on sugar levels, food intake, and chemical signals. Their similar shapes make it hard for scientists to create medicines that target just one type.

2.     NAD+-dependent activity of sirtuins

Sirtuins need NAD+ to work in your body. These special proteins act like tiny switches that control many body functions. SIRT1 links up with NAD+ to manage how your cells use sugar and fat.

The process creates O-acetyl-ADP-ribose and nicotinamide as end products.

SIRT1, SIRT3, SIRT4, and SIRT5 team up with NAD+ to keep your cell powerhouses healthy. These proteins help cells stay alive and work well. They change other proteins by taking off small chemical tags called acetyl groups.

This change helps control stress in cells and keeps them strong. p53 and FoxO proteins get modified by SIRT1 through NAD+ to protect cells from damage.

Regulatory Roles of Sirtuins in Cellular Biology

Sirtuins play a vital role in your cells by fixing DNA damage and protecting against stress. These special proteins act like tiny guards that keep your cells healthy through many different ways.

1.     Sirtuins and histone deacetylation

Your cells have special proteins called sirtuins that work as tiny switches. These proteins need NAD+ to work right and change how your genes turn on and off. The main job of SIRT1 is to remove acetyl groups from histones — the proteins that wrap up your DNA.

This process helps control which genes become active or stay quiet.

SIRT6 plays a big role in keeping you healthy by changing histone marks, too. It helps stop tumors from growing and makes you live longer. The way sirtuins change histones matters a lot for your health.

They help your body adapt when you don’t have much energy and fix problems in your cells. Scientists now make medicines that target these proteins to treat different health issues.

2.     DNA repair mechanisms

SIRT1 plays a vital role in fixing damaged DNA. This protein brings in other helpful proteins like BRCA1, Rad51, and NBS1 to spots where DNA needs repair. SIRT1 makes DNA fixes better by working with a repair protein called XPA.

The team-up between SIRT1 and XPA helps catch and fix DNA problems fast.

SIRT1 keeps DNA safe in two big ways. It changes how DNA wraps around proteins and brings in special tools to fix broken parts. This process stops harmful changes to cells and fights cancer growth.

SIRT1 also guards against damage from things that can hurt DNA, like too much oxygen in cells. These fixes help keep genes working right and slow down aging signs.

3.     Regulation of oxidative stress

Sirtuins act as your body’s defense team against harmful oxidative stress. These NAD+-dependent enzymes protect your cells from damage by turning on specific genes that fight off dangerous free radicals.

Your cells rely on three key sirtuins (SIRT1, SIRT3, and SIRT6) to manage oxidative stress levels and keep you healthy.

These powerful proteins help your body handle stress in many ways. They boost insulin production to control blood sugar and turn on special pathways that guard against cell damage.

Your body needs these sirtuins to stay strong and fight diseases linked to too much oxidative stress, like type 2 diabetes. The good news? Scientists now know how to target these proteins with new medicines to help protect your health.

Sirtuins and Metabolic Processes

Sirtuins play a vital role in your body’s energy use and storage. These proteins help control blood sugar, fat burning, and the power plants in your cells.

1.     Impact on glucose metabolism

Your body needs glucose control to stay healthy. SIRT1 plays a key role in this process by making your cells more sensitive to insulin. This protein helps your pancreas release insulin at the right time to support metabolic functions.

SIRT6 steps in to keep your blood sugar stable by turning on special transporters that move glucose into your cells.

Exercise turns on both SIRT1 and SIRT6 to improve how your body handles sugar. These proteins control important steps like glycolysis (where cells break down sugar for energy). They also manage gluconeogenesis, which is the process that makes new glucose when you need it.

Poor glucose control leads to health problems, but active SIRT1 helps prevent these issues.

2.     Role in lipid metabolism

Sirtuins play a vital role in fat control inside your body. SIRT1 turns on special switches called LXR and SREBP1c that control fat production. This process helps break down stored fats and stops new fat cells from forming.

During times without food, SIRT1 makes the body burn more fat for energy.

SIRT3 and SIRT6 also help manage body fats in different ways. SIRT3 starts up fat-burning tools in cells and fights harmful stress. The body needs SIRT6 to stop too much fat from building up in the liver.

These proteins work together like a team to keep fat levels healthy and balanced.

3.     Influence on mitochondrial function

Mitochondrial sirtuins play vital roles in your cell’s power plants. SIRT3, SIRT4, and SIRT5 control how your mitochondria make energy and handle stress. Your cells need SIRT3 to keep proteins working right and burn fat for fuel.

SIRT4 helps control insulin release by managing amino acids in your body.

Your mitochondria make more ATP energy thanks to SIRT3’s work on the electron transport chain. SIRT5 helps your cells breathe better and removes toxic ammonia through special proteins.

These tiny workers protect you from problems like aging, weight gain, and cell damage. Your body’s energy systems stay strong through these special proteins’ actions on key metabolic steps.

Sirtuins in Aging and Longevity

Sirtuins play a key role in slowing down aging through NAD+ pathways, and you’ll learn more about their amazing effects on longevity in the next sections.

1.     Anti-aging potential of sirtuins

Your body’s anti-aging fighters, called sirtuins, play a vital role in keeping you young. These proteins act like natural defense shields against aging by fixing damaged DNA and fighting cell stress.

Natural compounds such as resveratrol boost sirtuin levels in your body to slow down age-related problems. Exercise helps, too — it raises sirtuin activity to protect your cells from wear and tear.

RELATED: How to Naturally Fight the Aging Process

Caloric restriction makes sirtuins work better to extend life spans. Your sirtuin levels drop as you age, which leads to more cell damage and stress. The good news? You can fight back by staying active and eating foods rich in sirtuin activators like curcumin.

These simple steps help your body’s sirtuins keep working to maintain your health and slow aging effects.

2.     Mechanisms of senescence modulation

Sirtuins play a key role in controlling cell aging through senescence modulation. These proteins act as cellular switches that turn genes on or off to slow down aging. SIRT1, a major sirtuin protein, stops harmful cell changes by fixing damaged DNA and fighting stress in cells.

The NAD+ molecule helps sirtuins work better to protect cells from getting old too fast.

Cell aging slows down through specific steps that sirtuins control. They remove chemical tags from proteins, which changes how cells work and live longer. Sirtuins target genes that make cells stronger against damage.

They also help cells clean up waste and broken parts through a process called autophagy. These actions keep cells healthy and working well as time passes.

3.     Interaction with NAD+ and longevity pathways

NAD+ levels play a vital role in your body’s aging process. Your cells need NAD+ to power sirtuin proteins, which help you stay healthy and live longer. These levels drop by 50% between ages 40 and 60, making your cells work less well.

The decline affects how your body fixes DNA damage and keeps energy levels up.

Your body makes NAD+ through two main paths — one from scratch and one that recycles old parts. Nicotinamide riboside, a B3 vitamin form, boosts NAD+ in your system. Many studies show that higher NAD+ levels improve blood flow, help control blood sugar, and protect your heart.

Scientists now test NAD+ boosters in real people to help fix age-related health issues.

Sirtuins in Inflammation and Immune Regulation

Sirtuins play a vital role in your body’s defense against harmful inflammation. Your immune system works better with active sirtuins, which control how your body fights off sickness and keeps you healthy.

1.     Effect on inflammatory cells

Your immune cells respond to SIRT1’s powerful effects. SIRT1 stops harmful inflammation by turning down TNF-α production in your body. The lack of SIRT1 in dendritic cells leads to fewer T-cells that regulate immune responses.

SIRT2 helps your brain stay healthy by blocking TNF-α during inflammation.

SIRT3 makes your immune cells work better by changing them into M2 macrophages. These special cells fight inflammation in your body. SIRT6 plays a key role, too — more SIRT6 in macrophages means less inflammation.

Your NF-κB pathway gets modified by these proteins to keep inflammation under control.

2.     Influence on inflammatory mediators

Sirtuins play a vital role in controlling inflammation through specific proteins in your body. SIRT1 and SIRT6 directly affect key inflammatory proteins TNF-α and IL-6. These proteins work through a special pathway called NF-κB to reduce swelling and pain.

SIRT2 stops TNF-α from forming and helps calm brain inflammation.

SIRT3 makes special immune cells called M2 macrophages that fight harmful swelling in the body. These sirtuins back each other up — if one stops working, another steps in to help control inflammation.

Small RNA molecules in cells help control how much sirtuin gets made, which changes how the body handles swelling and pain. This process keeps your immune system in perfect balance.

3.     Regulation of inflammatory pathways

Your body’s inflammatory pathways need SIRT1 and SIRT6 to stay healthy. These proteins act like traffic cops for inflammation signals in your cells. SIRT1 helps your body switch from using sugar to burning fat during inflammation — a key process for staying balanced.

The latest research shows that higher SIRT1 levels lead to less chronic inflammation in your system.

Low SIRT1 in your body can trigger more inflammation and health issues. Your immune system relies on these proteins to work right in both short-term and long-term inflammatory states.

Medical science now targets these pathways to create new treatments for chronic inflammatory diseases. The key lies in boosting SIRT1 activity through specific proteins and enzymes that control metabolic balance.

Sirtuins in Apoptosis and Autophagy

Sirtuins control cell death through a process called apoptosis, which helps remove damaged cells from your body. Your cells also use sirtuins to clean up waste through autophagy, making them vital for your health and survival.

1.     SIRT1’s role in apoptosis regulation

SIRT1 plays a vital role in cell death control through its NAD+-dependent deacetylase actions. Your body needs this protein to remove acetyl groups from key molecules like P53, FOXO1/3/4, and NF-κB.

These changes help control whether cells live or die.

The NAD+/NADH ratio in your cells affects how well SIRT1 works. A higher NAD+ level makes SIRT1 better at removing acetyl groups. Your cells also change SIRT1 through steps like adding phosphate groups, which impacts its stability and function.

These processes link directly to your immune system’s balance.

2.     SIRT2-SIRT7 and autophagy mechanisms

Sirtuins play vital roles in your body’s autophagy process — the natural way cells clean themselves. SIRT3 keeps your mitochondria healthy and guards against cell damage. SIRT4 controls how your cells break down nutrients through glutamate dehydrogenase.

SIRT5 helps your cells breathe better by managing carbamoyl phosphate synthetase 1.

Your cells need SIRT6 and SIRT7 to fix DNA and stay healthy. SIRT6 fixes broken DNA strands and helps your metabolism work right. SIRT7 makes sure your cells make proteins correctly and repairs DNA damage.

These sirtuins work together to keep your cells running smoothly through autophagy — just like a cleanup crew for your body’s tiniest parts.

Sirtuins and Cancer Dynamics

Sirtuins play a major role in cancer growth and death. Scientists study these proteins to find new ways to fight different types of cancer.

1.     SIRT1 and breast cancer

SIRT1 plays a key role in breast cancer through its control of cell growth and survival. Your body’s SIRT1 protein affects cancer cells by changing how genes turn on and off. This protein works with NF-kB signals to slow down cancer growth.

The p53 protein, which SIRT1 helps control, decides if damaged cells live or die.

RELATED: Exercise and Cancer — Is there a Relationship?

Research shows SIRT1 levels change in breast cancer patients. Medical teams now look at SIRT1 as a way to spot breast cancer early. New cancer drugs target SIRT1 to stop tumor growth.

These treatments aim to change how SIRT1 works in cancer cells to make them weaker.

2.     SIRT6 in gastrointestinal and gynecological cancers

SIRT6 plays a vital role in fighting gastrointestinal cancers. Studies of 867 patients show that high SIRT6 levels lead to better survival rates. Your body uses SIRT6 to stop cancer cells from growing too fast.
