Gene Expression

You might have heard the term gene expression before, but what does that mean? Is gene expression what gives you your hair and eye color? Is it the reason you’re born with certain talents or a predisposition to certain diseases? Gene expression is actually responsible for keeping you alive.

Genes are subunits of DNA. They are the information databases of your cells. When your body needs something, whether it be more of a certain hormone, amino acids, or specific enzymes, gene expression occurs in the form of creating what your body specifically needs.

Gene expression, simply put, is when information stored in your DNA is turned into instructions for creating a usable product, like protein. These proteins perform essential functions as hormones, enzymes and receptors, and pathway signalers among other things. Pathway signaling genes have the potential to influence numerous biological responses.

????Redox Signaling Molecules

Now, let’s go a step further. Inside of each cell, you have something called redox signaling molecules. These molecules are like the high-speed internet of your cells. They are responsible for communicating with your genes when something is needed on a cellular level. They also communicate when a cell is getting old, sick, or damaged and needs to be replaced.

Unfortunately, things like aging, our diet, stress, and the environment affect these signaling molecules—think of them as getting a bit rusty—and a rusty signal simply does not work as well. Your redox signaling molecules have a harder time getting messages sent to your genes, and if they can’t get their messages sent, your genes have a much harder time maintaining a healthy immune system, fixing injuries, replacing old cells, and fighting disease.
