Figure Lengend Snippet: Effect of caveolin-1 (CAV-1) knockdown on transient receptor potential cation channel subfamily V member 4 (TRPV4)-mediated (GSK101) intracellular Ca2+ ([Ca2+]i) response to blockers of TRPV4 and KCa channels. The normal peak [Ca2+]i response to TRPV4 activation (GSK101) is markedly reduced from 597 ± 45 nM (n = 70) to 231 ± 47 nM (n = 85) following CAV-1 siRNA treatment (A and B). Furthermore, the apparent initial rate of TRPV4-mediated Ca2+ influx was markedly depressed from 108 ± 27 nM/min (n = 70) in normal conditions to 42 ± 16 nM/min (n = 85) in the presence of CAV-1 siRNA (C), reflecting a markedly depressed level of TRPV4 activation. The subsequent panels demonstrate that the typical normal peak elevation in [Ca2+]i following TRPV4 activation is markedly reduced upon inhibition of each KCa channel following CAV-1 knockdown. Iberiotoxin (IbTX) treatment reduces the peak [Ca2+]i for BK inhibition from 227 ± 34 nM (n = 73) to 84 ± 33 nM (n = 59) after CAV-1 siRNA treatment (D and E). TRAM-34 treatment reduces the peak [Ca2+]i for IK1 inhibition from 312 ± 31 nM (n = 90) to 81 ± 12 nM (n = 95) after CAV-1 siRNA treatment (F and G). Apamin treatment reduces the peak [Ca2+]i for SK3 inhibition from 414 ± 60 nM (n = 72) to 196 ± 23 nM (n = 60) after CAV-1 siRNA treatment (H and I). Therefore, after CAV-1 siRNA treatment the response for each of the KCa channels to TRPV4 activation is markedly depressed. ***P < 0.001. BK, large conductance Ca2+-activated K+ channel; IK, intermediate conductance Ca2+-activated K+ channel; SK, small conductance Ca2+-activated K+ channel.
