Charles P. Rabolli

md/phd candidate · rna biologist · computational pathology

I’m a physician-scientist in training at The Ohio State University, finishing my MD in the NIH-funded Medical Scientist Training Program. My PhD in Biomedical Engineering asked how a single chemical mark on messenger RNA, m6A, shapes the way the heart responds to stress and how the heart uses it to signal to the rest of the body. That work was supported by an NIH F30 fellowship and led to first-author papers in Circulation, JCI Insight, and RNA.

These days I’m focused on pathology and on how machine learning is changing it: I’m training clinically in pathology and have annotated whole-slide images for computational pathology research. I trained in the U.S., in Italy as a Fulbright Scholar, and in Germany. I’m also active in biotech entrepreneurship through Nucleate.

Where the mark sits on an mRNA matters

Nanopore direct RNA sequencing mapped METTL3-dependent m6A sites in adult cardiomyocytes. Whether the mark fell in the coding sequence or the 3′ UTR tracked with differences in protein output, and it pointed to targets in mitochondrial metabolism.

The heart helps set whole-body metabolism

On a Western diet, deleting METTL3 in cardiomyocytes protected mice from the diet's harmful effects, while raising it worsened weight gain, adiposity, and glucose intolerance. Cardiac m6A stabilizes FGF1 mRNA, a heart-to-fat signal.

An m6A reader drives cardiac growth under stress

Mice lacking YTHDF3 in cardiomyocytes showed less pathological remodeling after pressure overload. YTHDF3 controls stress-induced protein synthesis and cardiomyocyte size, which makes it a candidate cardioprotective target.
