(A) Exposure of HCLE cells to 150 mJ/cm2 UVB results in a decrease in [K+]i within 30 minutes, followed by recovery to normal levels by 90 minutes after exposure. Na+ moves into and out of the cells with the same time course. (B) The decrease in [K+]i and increase in [Na+]i in response to UVB are rapid, occurring within 10 minutes. *significantly different from all other values within groups (p ≤ 0.05, n=4) These, and all subsequent ion chomatography experiments were repeated 3 times with similar results.
