    Sublethal inhibition of mitochondrial Kv1.3 leads to cell cycle alterations. (A) FACS analysis of cell cycle of PANC-1 cells untreated or treated with clofazimine 1 µM and ShK 100 nM for 24 h. The distribution was determined by staining cells with 50 µg/mL Propidium Iodide and the acquisition was performed by a FACSantoII (Beckton Dickson). The plots are representative of three separated determinations. Light blue peaks represent apoptotic cells, while red peaks represent cells in G1 and G2/M phases. S phase is represented by the area with blue straight lines. A sub-G1 peak is due to dead cells. In the graph of untreated cells the labels and the arrows identify the different populations that are reported. (B) Cell cycle distribution in PANC-1 cells pretreated (lower panels) or not (upper panels) with 50 µM Mitotempo or 20 mM N-acetylcysteine (NAC) for 1 h, before the addition of mitochondrial Kv1.3 inhibitors PAPTP and PCARBTP (both at 100 nM) for 24 h. The experiment and the analysis have been performed as in (A) . The plots are representative of three separate measurements.

    Potassium channel Kv1.3 is expressed in PANC-1 cells. (A) Kv1.3 expression was determined by Western Blot in PANC-1 cells. 60 µg of total protein extract were loaded into a SDS gel and blotted onto a polyvinylidene fluoride (PVDF) membrane. Kv1.3 band was evaluated by immunoblotting with a specific antibody. GAPDH was used as loading control. The blot is a representative image of three different observations. (B) Inhibition of mitochondrial Kv1.3 by different concentration of membrane permeant blockers resulted in a reduction of the MTS signal from PANC-1 cells.

    Characterization of the Kv1.3 and Kv1.5 mutant channels containing the YS segment. A , average normalized activation and inactivation curves are shown as conductance-voltage relationships for Kv1.3, Kv1.5, the truncated Kv1.3-YS channel, and the chimeras Kv1.5-YS 532 and Kv1.5-YS 613 . All datasets were fitted to Boltzmann functions. Each data point is the mean ± S.E. of 6–11 cells. B , confocal images of non-permeabilized cells transfected with Kv1.3-YS-Cherry, Kv1.5-YS 532 -EGFP, and Kv1.5-YS 613 -EGFP. An extracellular anti-Kv1.3 antibody was used to label Kv1.3-YS ( green ), whereas the extracellular anti-Kv1.5 antibody was used for Kv1.5-YS 532 and Kv1.5-YS 613 chimeras ( red ). Nuclei were stained by Hoechst ( blue ). C , proliferation rate of the indicated channels or GFP-transfected cells (control) was determined by measuring EdU incorporation. Significant differences when comparing to Kv1.3 (*) or to control (#) are indicated. Statistical analysis was performed with one-way ANOVA followed by a Tukey's HSD multiple comparison. Each bar is the average of 9–15 determinations from 5 different assays. D , the average peak current amplitude obtained in cell-attached experiments for Kv1.5 channels and all the Kv1.5 chimeras was plotted against the % of the channels expressed at the plasma membrane ( upper graph ) or their normalized effect on proliferation (taking 100% as the proliferation rate of GFP-transfected HEK cells, lower graph ). The correlation between expression and current was fit to a linear regression curve ( y = 18.54 + 0.0066x, R 2 = 0.85, p = 0.008), but there was no correlation between proliferation and current amplitude ( R 2 = 0.23, p = 0.19).
