Overactive Bladder and Incontinence in the Absence of the BK Large Conductance Ca2+-activated K+ Channel
Open accessAbstract
BK large conductance voltage- and calcium-activated potassium channels respond to elevations in intracellular calcium and membrane potential depolarization, braking excitability of smooth muscle. BK channels are thought to have a particularly prominent role in urinary bladder smooth muscle function and therefore are candidate targets for overactive bladder therapy. To address the role of the BK channel in urinary bladder function, the gene mSlo1 for the pore-forming subunit of the BK channel was deleted. Slo(-/-) mice were viable but exhibited moderate ataxia. Urinary bladder smooth muscle cells of Slo(-/-) mice lacked calcium- and voltage-activated BK currents, whereas local calcium transients ("calcium sparks") and voltage-dependent potassium currents were unaffected. In the absence of BK channels, urinary bladder spontaneous and nerve-evoked contractions were greatly enhanced. Consistent with increased urinary bladder contractility caused by the absence of BK currents, Slo(-/-) mice demonstrate a marked elevation in urination frequency. These results reveal a central role for BK channels in urinary bladder function and indicate that BK channel dysfunction leads to overactive bladder and urinary incontinence.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
