Scientists at Texas A&M Health Institute combined caffeine with CRISPR gene editing to explore new ways to treat chronic diseases like cancer and diabetes. They developed a system that pairs CRISPR with caffeine to control when gene editing happens.

Coffee is something we all enjoy, but did you know it could help fight cancer? Scientists at the Texas A&M Health Institute of Biosciences and Technology believe it might. They combined caffeine with a powerful tool called CRISPR (clustered regularly interspaced short palindromic repeats) to explore new ways to treat chronic diseases like cancer and diabetes.

Their approach relies on a strategy called chemogenetics, which allows researchers to control cells using specific chemical signals. Yubin Zhou, professor and director of the Center for Translational Cancer Research at the Institute of Biosciences and Technology, focuses on studying disease at the cellular, genetic, and epigenetic levels.

The team developed a new chemogenetic system that pairs CRISPR with caffeine to control when gene editing happens. The process starts by preparing cells in advance. Using established gene transfer techniques, researchers insert genes that produce three key components: a nanobody, its matching target protein, and the CRISPR machinery.

Once inside the cell, these components are produced naturally. After this setup, the system can be controlled from the outside. When a person consumes about 20 mg of caffeine, such as from coffee, chocolate, or soda, it causes the nanobody and its partner protein to bind together. This interaction activates CRISPR, which then carries out specific gene modifications within the cell.

This strategy also makes it possible to activate T cells in ways that other gene editing approaches cannot. T cells act as the immune system's memory, preserving instructions from past infections so the body can respond quickly in the future.

Why It Matters

Understanding how gene editing works could lead to new treatments for cancer and diabetes. This research also highlights the potential of combining existing medications like caffeine with gene editing tools to create more effective therapies.
