mRNA expression levels of the genes ATP1A1 and ATP1B1 in the PBMC of COVID-19 (a) presenting normal FT3 (gray bars) and low FT3 serum values (black bars) and in hiPSC-CMs (b), treated with T3 at 1 nM (gray bars) and 100 nM (dark gray bars). Results are compared to those obtained in untreated hiPSC-CMs (white bars), used as controls (CTR) (light gray bars). Data have been retrieved from GEO public functional genomics data repository (GEO accession code GSE172348). *p < 0.05, **p < 0.005, ***p < 0.0005
