Photobiomodulation on KATP Channels of Kir6.2-Transfected HEK-293 Cells
Figure 3
Different concentrations of ATP on the KATP channel effects. (a) The potassium current increased in response to 0 mM ATP (inside out) and decreased in response to 10 mM ATP. No open channel event in 1 mM ATP was observed. HEK-293 cells expressing Kir6.2 was bathed in extracellular solution, and the patch membrane was held at 0 mV throughout the recording period. (b) Relationships between concentration and the ATP inhibition of KATP channels.
