Fig. 3. Electrophysiological responses to chemical deterrents. No
electrophysiological change was seen in response to application of oroidin (A)
or sceptrin (B). A mixture of ectyoplasides A and B caused a slight change in
current (C), indicating activation of CFTR via the Gs
signaling pathway, which was not observed in control cells (D). Iso,
isoproterenol; Oct, octanal.
