What Is Methylation

You know how people often say ‘you are what you eat?’ Well, when it comes to the science of genetics, a similar concept applies – you are, in part, what your genes are doing.

One of the key processes in this is something called methylation. It’s a simple but crucial biological process, altering the function of your genes and affecting everything from your mood to your overall health.

When folate from food or folic acid is consumed, the MTHFR enzyme converts vitamin B9 into its bioactive form called methylfolate or 5-methyltetrahydrofolate. This activated form can serve as a methyl donor for various health functions, such as heart health, brain function, detoxification, energy production, and immune support. Specifically, methylfolate donates a methyl group for the conversion of homocysteine into methionine.

But, how exactly does it work and why should it matter to you? Let’s explore that together.

DNA methylation

While you may not be familiar with it, DNA methylation plays a vital role in regulating gene expression in your body. It’s a biological process that alters the activity of your DNA, without changing the sequence. It’s like adding extra notes to a musical score, instructing the cells how, when, and where to use the DNA.

The process involves the addition of a methyl group to the DNA molecule. This process can affect the function of a gene, turning it off or on, like a switch, based on your body’s needs. The patterns of DNA methylation are unique to each individual, like your personal genetic fingerprint.

You should know that the level of DNA methylation in your cells, can influence your health. High or low these levels can indicate potential health issues. DNA methylation profiling, a method of identifying these levels, helps to understand your body better.

What is methylation?

Now, let’s delve deeper into understanding what methylation really is. It’s a biochemical process that plays a crucial role in how your genes function. It’s like a switch that can turn your genes on or off. Think of your genes as a blueprint and methylation as the construction crew that reads and follows that blueprint.

Methylation happens when a molecule called a methyl group attaches to specific sites on your DNA, these are your methylation sites. This process affects the proteins your genes produce, influencing everything from your physical characteristics to your health.

This cycle is a continuous process that happens millions of times every second in your cells. It’s a complex dance of adding and removing methyl groups to and from your DNA. This constant adjusting is how your body responds to its ever-changing needs.

It’s amazing, isn’t it? This intricate process is constantly happening inside you, dictating how your genes operate. You’re a part of something bigger, a never-ending cycle of biochemical reactions that play a role in who you are. You’re not just a bystander, you’re an active participant in the wonder of life.

What is the role of methylation?

Primarily, methylation plays a crucial role in gene expression – the process by which information from a gene is used to create functional products like proteins. This process can turn off, or ‘silence,’ certain genes, a process known as transcriptional silencing. This is vital in controlling the functions of cells and maintaining the health of your body.

Moreover, it is a key player in:

• Cell differentiation: As your cells divide and grow, the process guides them to develop into specific types, like skin, heart, or brain cells.
• The biological process: It helps in various biological processes like DNA repair and replication.
• Pattern of DNA methylation: It helps establish a unique pattern on your DNA, which contributes to your individual biological makeup.

However, when this process goes awry, aberrations can occur. These aberrations can lead to diseases like cancer.

Causes of suboptimal methylation

Your body’s methylation process can falter due to several factors. Diseases, environmental factors, and poor nutrition can all contribute to this issue. More specifically, folic acid deficiency is often associated with poor methylation.

DNA methylation perturbations and irregular histone methylation patterns can also cause suboptimal methylation. Both of these can lead to gene repression, which in turn affects your body’s overall health. Similarly, exposure to endocrine disruptors can impede the methylation process.

You could have the MTHFR gene variant which hinders the the production of folate and folic acid 

Consequences of suboptimal methylation

When methylation in your body is suboptimal, it can lead to several adverse health consequences. Methylation, a crucial process in your human genome, can be disrupted by various factors. This can trigger disease-associated changes, impacting your health significantly.

As a part of our community, it’s important for you to understand these changes. Here are three key consequences you should be aware of:

• Disruption of tumor suppressor genes: May interfere with these genes, encouraging the growth of tumors.
• Altered epigenetic marks: These marks are altered, leading to potential health issues like cancer or neurological disorders.
• Changes in protein binding: Can affect the binding of methyl-binding proteins, methyl-cpg-binding proteins, and transcription factor binding, disrupting normal cellular function.

Suboptimal methylation can have far-reaching implications, altering your body’s normal functioning and paving the way for serious health issues. We believe it’s crucial for you to understand these effects to stay informed and take necessary measures for your well-being. Remember, your health is a collective concern, and we’re in this journey together.

What are Nutrigenomics?

Have you ever wondered about Nutrigenomics and how it connects your nutrition with your genes? Nutrigenomics is a fascinating field that explores the relationship between what you eat and how your body responds at a genetic level. It’s like a conversation where food is the language and your genes are the listeners.

The essence of this interaction lies in atoms, the elemental building blocks of our world. Your food contains atoms like hydrogen and nitrogen, which can influence the nucleic acid in your genes. This is where methylation, a process involving the addition of a methyl group (a carbon atom and three hydrogen atoms), comes into play.

Think about it this way: you’re creating a unique blend of paternal genomes, mixing and matching to pass onto your embryonic stem cells. These cells evolve into daughter strands, carrying forward your unique genetic narrative.

How to learn about your own methylation cycle

Methylation, a crucial biochemical process, influences everything from your brain health to your immune responses. Learning about your methylation cycle can be empowering, paving the way for better health outcomes.
