Oleic Acid Inhibits the KATP Channel Subunit Kir6.1 and the KATP Current in Human Umbilical Artery Smooth Muscle Cells

The study demonstrated that OA inhibited Kir6.1, a KATP channel subunit, in HUASMCs, and indirectly inhibited the KATP current. In addition, the results indicated that NO and/or GFX partially reversed OA inhibition in HUASMCs.
