The Initial COVID-19 Reliable Interactive DNA Methylation Markers and Biological Implications
1School of Computer, Data and Information Sciences, University of Wisconsin, Madison, WI 53706, USA.
This study identified novel DNA methylation biomarkers for predicting COVID-19 with high accuracy. These epigenetic markers may also offer new insights into viral behavior and potential therapeutic targets.
Area of Science:
- Epigenetics
- Genomics
- Virology
Background:
- Previous research confirmed interactive genomic biomarkers.
- Reliable DNA methylation biomarkers, especially interactive ones, remained undiscovered at the epigenetic level.
Purpose of the Study:
- To identify novel DNA methylation biomarkers for predicting COVID-19.
- To explore the interactive potential of CpG sites and their association with disease subtypes.
- To investigate the implications of these biomarkers for understanding viral nature and potential treatments.
Main Methods:
- Analysis of 865,859 methylation sites using Infinium MethylationEPIC array.
- Identification of two sets of eight interacting CpG sites (genes).
- Validation of biomarker performance in predicting COVID-19 patients.
Main Results:
- Discovery of two sets of eight interacting CpG sites with nearly perfect accuracy (96.87-100%) in predicting COVID-19.
- These CpG sites explain post-COVID-19 conditions and represent potential druggable targets.
- Specific CpG sites (cg16785077, cg25932713, cg22930808) suggest SARS-CoV-2 might behave as a DNA into RNA virus.
Conclusions:
- Novel DNA methylation biomarkers enable highly accurate COVID-19 prediction.
- These biomarkers offer insights into post-COVID-19 conditions and potential therapeutic strategies.
- Findings challenge the current understanding of SARS-CoV-2 as an RNA virus, proposing a DNA-to-RNA mechanism.
