NOTCH1 and infection: In the infection group, Notch 1, RBP-J, JAG1, and HES1 protein levels were significantly inhibited compared to the control group, while 25 to 50 mg/kg of baicalin increased the protein expression levels of Notch 1, RBP-J, JAG1, and HES1 compared to the infection group (p < 0.05), as shown in Figure 5B,F,J,N.
