NEUROG1 and infection: As shown in Fig. 5, the expression of Ngn1 in C17.2 NSCs after treatment with Ad-ROP18 for 3 days (0.8073 ± 0.0700) was inhibited, significantly lower than that in the Ad group (1.485 ± 0.1259) (t(4) = 4.647, P = 0.009) and the non-infection group (3.848 ± 1.042) (t(4) = 2.901, P = 0.044).
