UCA1 and infection: Instead, its involvement is documented in other contexts, such as cancer, sepsis, acute respiratory distress syndrome unrelated to COVID-19, and infection by other viruses like hepatitis C. UCA1 is particularly interesting because (i) its known regulatory role in viral infections, (ii) its altered expression in SARS-CoV-2 infection, (iii) the presence of multiple m6A-modified DRACH motifs, and (iv) its predicted interactions with miR-145 and SARS-CoV-2 RNA (Table 7).
