( A , B ): Simultaneous measurements of changes in the membrane potential ( A ) and [Ca 2+ ] i ( B ) in the three different cells [a (black), b (blue), and c (red)], following the application of a selective K Ca 3.1 <t>activator,</t> <t>SKA-121</t> (1 μM), and/or the K Ca 3.1 inhibitor, TRAM-34 (1 μM) using DiBAC 4 (3) and Fura 2, respectively. The relative time-course changes in fluorescence intensities (1.0 at 0 s) from three different THP-1-derived M 2 macrophages are shown. ( C ): Real-time PCR examination of K Ca 3.1 expression in THP-1-derived M 0 macrophages (‘M 0 ’) and M 2 macrophages (‘M 2 ’). Expression levels are shown as a ratio to ACTB ( p > 0.05, n = 4 for each). ( D , E ): Protein expression levels of K Ca 3.1 in the ‘M 0 ’ and ‘M 2 ’ groups were determined by Western blot.

Effects of treatment with a CREB inhibitor on expression levels of IL-10, IL-8, VEGF-A, and TGF-β1 transcripts and on phosphorylated P-CREB protein levels following the SKA-121 treatment and high [K + ] e exposure in THP-1-derived M 2 macrophages. ( A – D ): Real-time PCR examination of IL-10 ( A ), IL-8 ( B ), VEGF-A ( C ), and TGF-β1 ( D ) expression in THP-1-derived M 2 macrophages treated with vehicle and 1 μM 666-15 for 24 h. Relative mRNA expression in the vehicle control is expressed as 1.0 (n = 4 for each). E-F: Western blot showing P-CREB and total CREB (CREB) in 1 μM SKA-121-treated ( E ) and high [K + ] e -exposed ( F ) THP-1-derived M 2 macrophages. Specific band signals for P-CREB and CREB were observed at approximately 40 kDa. G, H: Summarized results of the relative protein expression of P-CREB/CREB in 1 μM SKA-121-treated ( G ) and high [K + ] e -exposed ( H ) THP-1-derived M 2 macrophages. After compensation with the optical density of the ACTB signal, the expression level in the vehicle control or 5 mM K + is expressed as 1.0 (n = 4 for each). **: p < 0.01 vs. the vehicle control or 5 mM K + .

Effects of treatment with SKA-121 on expression levels of IL-10, IL-8, VEGF-A, and TGF-β1 transcripts and IL-10 and IL-8 secretion in human prostate cancer PC-3 cell-cultured medium-treated THP-1-derived M 2 macrophages. ( A – D ): Real-time PCR examination of IL-10 ( A ), IL-8 ( B ), VEGF-A ( C ), and TGF-β1 ( D ) expression in PC-3 media-treated THP-1-derived M 2 macrophages treated (+) or untreated (−) with 1 or 10 μM SKA-121 for 24 h. Relative mRNA expression in the group untreated with PC-3 medium is expressed as 1.0 (n = 4 for each). ( E , F ): Quantitative detection of IL-10 ( E ) and IL-8 ( F ) secretion by an ELISA assay in THP-1-derived M 2 macrophages treated or untreated with SKA-121. Relative secretion in the group untreated with PC-3 medium is expressed as 1.0 (n = 4 for each). **: p < 0.01 vs. the vehicle control (−/−).
