Everything Epigenetics
Don’t understand epigenetics? Don’t worry. There was a time when genetic analysis was hardly known or understood. Now, genetic analysis is performed by thousands of companies and your full genome can be decoded for less than $100. Epigenetics is how your behaviors change your outcome. Epigenetics gives us knowledge on how to change your life, and the ability to read biology to understand your current health status. You ARE in control. Your host, Hannah Went, is here to discuss the insights which can improve your life and health. She is here to bring you Everything Epigenetics, simplified.

Unlocking the Epigenome from a Single Drop of Blood with Dr. Toinét Cronjé
In this week’s Everything Epigenetics episode, I speak with Dr. Toinét Cronjé about what epigenetics can do for the field of epidemiology.
Epidemiology is the study of the distribution and determinants of health-related states or events in populations and the application of this study to control health problems. By studying epigenetics and epidemiology in tandem, Dr. Cronjé seeks to understand patterns of diseases in populations, identify risk factors, and develop strategies to prevent or control health issues.
More specifically, Dr. Conjé researches epigenetics in understudied populations including the association between DNA methylation and noncommunicable diseases and how DNA methylation clocks perform in these groups.
By making the most of the data we have available at the moment (from high-income countries) and of opportunities provided to researchers like herself to work at leading universities like the University of Copenhagen, she hopes that we will get closer to finding the tools to ease the burden on the research communities in low and middle income countries (LMICs).
If we can truly start to investigate data from LMICs can you imagine the richness of the information we will unearth?
Many of the questions that we are struggling with will be easier to address if we have more diversity in research data sets (e.g. genetics, cultural, dietary, and environmental), as rich (diverse) data sets allow researchers to see more angles to approach their questions from that they might not have been able to see before.
Dr. Cronjé’s hope is to develop blood-based screening tools for a disease. Only then, when disease screening is accessible to all (e.g. through a blood test instead of intensive and invasive procedures) will we actually know what proportion of populations around the world actually suffer from diseases like these.
Using that as a starting block we can finally proceed to addressing stigma and improving care.
In this episode of Everything Epigenetics, you’ll learn about:
- Toinét’s unique background
- OMIC epidemiology
- What epigenetics does for epidemiology
- The importance of biobanks
- What we can tell you about yourself when investigating the epigenome using an archived sample from a biobank
- Why it’s important to research understudied populations
- What we can learn from low and middle income countries
- What the research community is missing out on by not studying these groups
- Noncommunicable diseases (NCDs)
- The association between DNA methylation and NCDs
- The urban-rural divide which provides a unique opportunity to investigate the effect of the combined presence of multiple forms of environmental exposure on DNAm and the related increase in disease risk
- Toinét’s study on “Comparison of DNA methylation clocks in black Sout
