Peptide KKP1 treatment induces the transcriptional activity
of
the Nrf2/ARE signaling pathway. (A) Schematic representation of the
Nrf2 luciferase reporter constructs shown in the top panel, while
the bottom panel represents the experimental protocol of this assay.
(B) Relative luciferase activity in HSC-T6 cells transfected with
the Nrf2/ARE reporter constructs undergoing KKP1, KKP2, and KKPs treatment
for 4, 8, 16, and 24 h. (C) Corresponding p-value
plot of the data pairs shown in (B). No significance of the 4 h treatment
was shown. (D) Bar graph shows the AUC analysis of (B). (E) Western
blot analysis of the GCLC and HO-1 protein levels in HSC-T6 cells
incubated with KKP1, KKP2, and KKPs for 8 h. (F) Densitometric quantification
of the GCLC and HO-1 proteins in the blots shown in (E). Data in the
graph are means ± SEM of three independent measurements. (G)
Corresponding p-value plot of the data pairs shown
in (F).
