Dectin-1 and NF-κB signaling pathways involve PGLYRPs induction in HCECs exposed to HKCA.

<p>A. The HCECs were exposed to 10<sup>6</sup> cells/ml HKCA with prior incubation in the absence or presence of isotype IgG (10μg/ml), dectin-1 Ab (10μg/ml), BAY11-7082 (10μM) or NF-κB activation inhibitor quinazoline (NF-κB-I, 10μM) for 1 h. Cultures treated by HKCA for 4 h were subjected to RT-qPCR to measure mRNA. B. Total protein of HCECs treated for 48 hours was extracted with RIPA buffer for western blot to examine PGLYRP-2 production. C. Protein levels of PGLYRP-2 were evaluated by western blot using β-actin as control with quantitative ratio of PGLYRP-2/β-actin. Results shown are the mean ± SD of four independent experiments; *** p<0.001, as compared with normal control; ^^ p<0.005, ^^^ p<0.001, as compared with HCECs exposed to HKCA.
