Aim: To elucidate the transcriptional characteristics of COVID-19. Materials & methods: We
utilized an integrative approach to comprehensively analyze the transcriptional features of
both COVID-19 patients and SARS-CoV-2 infected cells. Results: Widespread infiltration of
immune cells was observed. We identified 233 genes that were codifferentially expressed in
both bronchoalveolar lavage fluid and lung samples of COVID-19 patients. Functional
analysis suggested upregulated genes were related to immune response such as neutrophil …
Aim
To elucidate the transcriptional characteristics of COVID-19.
Materials & methods
We utilized an integrative approach to comprehensively analyze the transcriptional features of both COVID-19 patients and SARS-CoV-2 infected cells.
Results
Widespread infiltration of immune cells was observed. We identified 233 genes that were codifferentially expressed in both bronchoalveolar lavage fluid and lung samples of COVID-19 patients. Functional analysis suggested upregulated genes were related to immune response such as neutrophil activation and antivirus response, while downregulated genes were associated with cell adhesion. Finally, we identified LCN2, STAT1 and UBE2L6 as core genes during SARS-CoV-2 infection.
Conclusion
The identification of core genes involved in COVID-19 can provide us with more insights into the molecular features of COVID-19.
