Dengue virus NS1 leads to downregulation of HNF4 alpha in liver cells resulting in a decrease in coagulation factors I, V, X, and XIII, contributing to coagulopathy.

Unlabelled: Dengue virus NS1 protein is a major pathogenic protein. In this study, we examined the role of NS1 in coagulopathy associated with Dengue infection, a common feature of Dengue virus pathogenesis. Since most coagulation factors are produced by hepatocytes and liver is key organ affected during infection, we conducted transcriptomics using total-RNA extracted from Huh7 cells overexpressing NS1 protein.
