ATP2B1 and COVID-19: The data obtained from qPCR analyses (see Appendix Table qPCR data) showed upregulated levels of viral N gene (as the positive control) and downregulated levels of ATP2B1 in the cells infected for 48 h, in comparison to T0 data (fold: 0.7, see Fig. 1I), thus suggesting that the decrease in ATP2B1 levels is not an “early event” during viral infection as also confirmed in lungs from COVID-19 patients (Fig. EV1H).
