Fig. 6: ERK/NF-κB signaling is involved in Kv1.3-related M1 macrophages.

A Respective western blotting image and densitometry analysis of ERK/NF-κB signaling after transfection with LV-Kv1.3 in THP-1 cells. Data were expressed as mean ± SD (n = 4). B The phosphorylation signal data are depicted in the form of stacked histogram overlaid plots. The mean fluorescence intensity (MFI) of the ERK1/2 and NF-κB p65 phosphorylation signal was expressed as the mean ± SD (n = 3). C Effects of MgTx, PD98059, and Licochalcone B on Kv1.3 and ERK/NF-κB signaling in LV-Kv1.3-transduced THP-1 cells were analyzed by western blotting. Data were expressed as mean ± SD (n = 3). D Respective western blotting image and densitometry analysis of ERK/NF-κB signaling in HK-2 cells co-cultured with the supernatant from LV-Kv1.3-transduced THP-1 cells for 48 h. Data were expressed as mean ± SD (n = 4). E Respective western blotting image and densitometry analysis of ERK/NF-κB signaling in mice subjected to UUO (7 days post-surgery) and IRI. Data were expressed as mean ± SD (n = 4).
