Fig. 3From: Comparison of renal histopathology and gene expression profiles between severe COVID-19 and bacterial sepsis in critically ill patientsRenal tissue ACE2 and CD147 mRNA levels in critically ill patients with COVID-19-associated AKI (SARS-CoV-2) (n = 6), bacterial sepsis-associated acute kidney injury (Sepsis) and control subjects (n = 12). Messenger RNA (mRNA) expression was determined by reverse transcription quantitative polymerase chain reaction using glyceraldehyde-3-phosphate dehydrogenase (GAPDH) as a housekeeping gene. **p < 0.01, ****p < 0.0001Back to article page
