Fig. 6From: 18β-Glycyrrhetinic acid induces human HaCaT keratinocytes apoptosis through ROS-mediated PI3K-Akt signaling pathway and ameliorates IMQ-induced psoriasis-like skin lesions in miceGA ameliorated IMQ-induced psoriasis-like skin lesions in mice. (A) The macroscopic appearance of mouse back skin on day 14. (B) H&E staining of the mouse skin on day 14. (C) PASI scores of mouse back skin lesions on day 14. **P < 0.01. (D) The relative expression of TNF-α, IL-22 and IL-17A in skin lesions on day 14 was measured using RT-PCR. GAPDH served as an internal reference. *P < 0.05. **P < 0.01Back to article page
