Gene expression levels for Mmp2 (coding for metalloproteinase 2), Ecm1 (coding for extracellular matrix protein 1) and Lcn2 (coding for lipocalin 2) were also higher in SARS-CoV-2-infected obese NASH animals than in infected lean controls (D4). The gene discussed is ECM1; the disease is metabolic dysfunction-associated steatohepatitis.
