Results showed null expression of viperin in mock-infected HT-29 cells (Figure 1a), whereas viperin expression was detected in RV-SA11-infected HT-29 cells as early as 3 hpi and progressively intensified with increasing time points (Figure 1b), suggesting that rotavirus infection induced heightened expression of viperin. The gene discussed is RSAD2; the disease is Rotavirus infection.
