CFTR-inhibitor 172 does not prevent acceleration of the beat by NaHCO3
Medium | Beat Frequency (Hz)
(Mean ± SEM) |
---|---|
HS | 2.33 ± 0.23a,c |
HS + 15 mM NaHCO3 | 6.70 ± 0.32b,c |
HS + 10 μM CFTR-i172 | 2.84 ± 0.15a,d |
HS + 10 μM CFTR-i172 + 15 mM NaHCO3 | 6.25 ± 0.30b.d |
Not significantly different (P>0.15, paired t-test)
Not significantly different (P>0.35, paired t-test)
Significantly different (P<0.001, paired t-test)
Sperm were bathed for 5-10 min with medium HS in the presence or absence of 10 μM CFTR-i172. Representative sperm were selected for waveform analysis then perfused for 1 min with the same medium supplemented with 15 mm NaHCO3 and resampled.
