If you stretched the DNA in one cell all the way out, it would be about 6 feet long. If you strung all the DNA in all your cells end to end, the length of that tiny thread of DNA would be about twice the diameter of the Solar System.
How does that much DNA fit into our tiny cells without getting tangled up? It’s really REALLY good at wrapping itself up.
Keep reading as we unravel your DNA to find out where Methylation and Gene Expression begins.
Humans have 23 chromosomes. They’re found in the nucleus of every cell, and are made up of your DNA wrapped really densely around little proteins.
A Nucleosome is what we call the bundle of “DNA wrapped around 8 histones in a tight group” – If DNA was a thread, a Nucleosome would be the spool you store that thread on.
Staying on that ‘Thread/Spool’ analogy – If a Nucleosome was the spool, then the histones would be the wood that the spools are made of. Histones are small proteins that can subtly warp to change how the DNA is wrapped around them.
Histone modification is a type of Epigenetic change, but not the one we focus on.
Our genetic code! All the recipes that make up you and me are contained in that tightly wound little thread. But what about individual steps in the recipe? That’d be….
Groups of genes work together to change the functions and forms in your body. They describe how proteins should fold, and how messages get passed around. How much fat your body stores, or how quickly your cells should heal themselves. However, just because you have a gene, doesn’t mean it’s being used. That’s up to the…
Your body turns those ‘recipes’ into physical changes by reading your genes, and creating proteins per those instructions.
When you increase or decrease how well that gene is being read, you’re changing the gene expression.
You might have a certain gene in your DNA, but if it never gets turned on, then you’ll never outwardly show that gene’s traits.
Sometimes, a few genes can get together and express strongly to make new effects. This is how some people have brown eyes, even though both their parents have blue eyes.
But Gene Expression isn’t just ‘on’ or ‘off’ – it’s more like a dimmer switch, that can change on a sliding scale.
What controls those degrees of expression? Finally, we arrive at…
A molecule called a Methyl Group can attach to your DNA at certain locations, and can detach as well. This process is called Methylation and DeMethylation.
It doesn’t change your DNA itself! Instead, Methyl Groups become that gene’s dimmer switches – turning up or down the gene’s expression, based on how many methyl groups attached.
A gene turning on when it’s supposed to stay off could make a protein fold wrong and create conditions like Parkinson’s disease, or cystic fibrosis. So, genes expressing properly is important.
Methyl groups attach and detach to your DNA throughout your life. They act in response to outside factors, like how much sleep you’re getting, whether you smoke or not, what your diet is like, and much more.
When something changes gene expression without changing the DNA itself, that’s Epigenetics.
DNA Methylation is a type of Epigenetic Marker. There are also a few other Epigenetic Markers, like histone modification.
Learn about how we use Epigenetics to discover your Biological Age in the next tab.
Aging is defined by your cells steadily losing their ability to function. Losing cell function shows up on our body in things like gaining wrinkles (skin losing elasticity) or worsening eyesight.
Many aspects of cell function is controlled by Gene Expression.
DNA Methylation – the Epigenetic marker that our laboratory examines – is able to control gene expression.
The genome is your body’s recipe book. Different areas of the body, like the brain and skin, read different chapters from that book. DNA Methylation can act as a biological white-out, changing phrases, sentences, and even entire recipes. This reversible process is your body’s way of controlling what parts of your genome are read.
By analyzing the patterns of DNA Methylation we can check if your biological systems are aging faster or slower than the average person your age, look for markers that could indicate a high risk of age-related disease, and much more.
We can see if your Biological Age is faster or slower than your Chronological Age, along with many other insights into your health and aging, included in the TruAge Collection.
60% of DNA Methylation CHANGES throughout your life – it’s not a one-way process! DNA Methylation responds to nutrition, exercise, sleep, stress, and other environmental factors.
Studies also show that reducing your biological age by 7 years can cut your likelihood of developing age-related diseases (like Alzheimer’s Disease) in half. So it’s not just your lifespan you’re improving, but also how healthy you’ll be throughout it.
Biological Age is strongly correlated to both lifespan and healthspan – the length of your life, and the quality of your health throughout it.
Your Biological Age can be slowed, and even reversed, by applying lifestyle changes. While scientists believe about 40% of your Methylation is out of your hands, due to what you inherited from your parents or experienced in childhood – that still leaves over half of your gene expression in your own hands.
And much more…
How low should you get your Biological Age?
As low as you can!
When your Biological Age is less than your Chronological Age, it means you’re living a lifestyle that is actively helping you lengthen your lifespan and reduce your incidence of disease. The bigger that gap, the better!
Of course, the opposite applies if you head in the opposite direction. When your Biological Age is significantly higher than your Chronological Age, a lot of chronic health conditions become more likely.
Chronological Age is just your birthday – how long you’ve been on this earth. It isn’t very relevant to how you feel and function.
Many diseases occur at higher rates when you get older, because more and more of your cells aren’t functioning the way they should, but this isn’t controlled by how many times you’ve gone around the sun.
Biological Age is deeply tied to your long-term health. It’s measured by how well your cells are aging – how well your DNA is giving them accurate, healthy instructions, so they can do their job properly and keep your body in tip-top shape.
Biological Age is constantly changing in response to your external stimuli and stressors. Scientists have found that Biological Age measured by DNA Methylation is the most accurate predictor of healthspan (how healthy you are) and lifespan (how long you will live) than any other biomarker.
A higher Biological Age is correlated with a higher risk of developing age-related diseases (Like Alzheimer’s Disease and Cancers). A lower Biological Age is correlated with reduced risk of disease, and a longer lifespan.
If you could reverse your risk of age-related disease, wouldn’t you want to know how?
Calcium Alpha-Ketoglucarate is a special form of mineral calcium.
We chose this ingredient due to its positive impacts on lifespan, healing, and its assistance in fighting age-related disease.
A multi-year controlled study on mice found calcium alpha-ketoglucarate “promotes longer, healthier life, associated with a decrease in levels of inflammatory cytokines. Strikingly, the reduction in frailty was more dramatic than the increase in lifespan”
Studies on Alpha-Ketoglucarate have shown that it improves the senescence-associated phenotypes of bone marrow, and promotes healthy gene expression to slow and even reverse the cellular aging that results in osteoporosis. It increased the bone mass, and reduced age-related bone loss. It also accelerated healing of damaged bone and improved age-associated epigenetic markers.
EGCG is found naturally in Green Tea, and is the main reason why green tea is popularized as a therapeutic drink.
We chose this ingredient due to its proven and positive impacts on reversing and treating diseases, its powerful effect fighting cancers, and its help in regulating healthy gene expression.
Epigallocatechin-3-gallate (EGCG) is a type of Catechin – a natural antioxidant that helps to prevent cell damage. It has been shown to offer multiple effects on human pathological and physiological processes. It offers antioxidant, anti-inflammatory, anticollagenase, and antifibrosis effects.
More interestingly in our line of work, EGCG has been found to reactivate methylation-silenced tumor suppressor genes. In other words, it helps to remove epigenetic markers and ‘wake up’ genes that naturally prevent cancer from developing in the first place.
Sulforaphane is a natural plant compound found in cruciferous vegetables, like broccoli and brussels sprouts. It’s well-known for its antioxidant, antimicrobial, and anti-inflammatory properties.
While it has a ton of health benefits, we chose this ingredient because of its effective support of epigenetic regulation and interdependence in the body’s fight against cancer.
Pterostilben is a type of polyphenol created naturally within the body, but can also be found in almonds, grape leaves, and Vaccinium berries (like blueberries).
We included this ingredient because of research showing its positive effect on lifespan, age-related disease, and health maintenance.
Several studies have found that polyphenols like Pterostilbene and rapamyacin protect against age-related diseases like arthritis, osteoporosis, Alzheimer’s disease, and cardiovascular disease.
Pterostilbene has become popular because of its remarkable pharmacological activities, such as anti-tumor, anti-oxidation, anti-inflammation, and neuroprotection.
Pterostilbene can be rapidly absorbed and is widely distributed in tissues, but it does not seriously accumulate in the body.
Humans naturally create Vitamin D when exposed to sunlight, but many aren’t getting enough – either because they have a harder time synthesizing it, or because they don’t get enough sun exposure for their skin to start.
We included this ingredient because it has been found to slow biological aging and improve vital bodily functions.
Studies have shown that Vitamin D supplementation increased telomerase activity, suggesting an anti-aging effect. A recent study found that Vitamin D supplementation may slow down Epigenetic Aging as measured by DNA methylation.
Beyond its anti-aging effects, it also supports the function of your muscles and immune system. Vitamin D also aids calcium absorption, helping your bones and teeth stay strong.
DHEA is the most abundant steroid hormone created in the human body.
The levels of DHEA in the human body decline as they age, and numerous studies show a preventative role for DHEA on various age-related diseases, its ability to enhance the immune system, and its power to fight against diabetes, obesity, cancer, memory decline, and aging.
Folate, Methylfolate, and Folic Acid are different forms of Vitamin B9.
Folate and Methylfolate are more immediately bioavailable.
Folate is naturally present in a wide variety of foods, including vegetables (especially dark green leafy vegetables), fruits and fruit juices, nuts, beans, peas, seafood, eggs, dairy products, meat, poultry, and grains.
Many countries have mandatory folate fortification programs, adding folic acid into enriched grain foods like bread, pasta, and rice in order to reduce the population’s risk of serious birth defects like Anecephaly and Spina bifida.
Folates are essential to build and replicate DNA, and are highly involved in methylation, cell proliferation, and differentiation.
One of the known associations in treatment-resistant depressed patients is lower levels of L-methylfolate. It is the only form of folate that crosses the blood–brain barrier and is immediately available for neurotransmitter synthesis.
It is also involved in key cellular activity to reduce the risk of depression, dementia, and stroke.
Recent studies have shown that decline in cellular nicotinamide adenine dinucleotide (NAD+) levels cause aging-related disorders.
Since NMN chemically changes into NAD+ in the body, supplementation of NMN effectively boosts the body’s available NAD+ to promote healthy cellular aging, maintain healthy DNA and many other key celluar processes.
NMN supplementation has been found to promote anti-aging miRNA expression profiles, reversing age-related changes in vascular function in mice, and appeared to rejuvenate faltering mitochondria (the cell’s energy factories).
Another study backed up those results in a human trial, showing that the compound NMN improved expression of genes that are involved in muscle structure and remodeling.
It additionally improved the ability of insulin to increase glucose uptake in skeletal muscle, which often is abnormal in people with obesity, prediabetes or Type 2 diabetes.
