A study of differential circRNA and lncRNA expressions in COVID-19-infected peripheral blood

we found a total of 570 circRNA that have difference, among which 155 are up-regulated and 415 are down-regulated; and 898 lncRNA that have difference, in which 414 are up-regulated and 484 are down-regulated; and 476 mRNA that have difference, in which 98 are up-regulated and 378 are down-regulated. In this work, we sequenced circRNA, lncRNA and mRNA from recurrent COVID-19 patients and healthy people, and compared the differences. In this study, total RNA was extracted from the whole blood of three recurrent COVID-19 patients and three healthy people for further microarray analysis.
