The coverslips were incubated in a Ca ++-free solution containing fura-PE3 (AM) and pluronic acid (Texas Fluorescence Labs, Austin, TX) for 30 min., washed, then incubated in a Ca ++-containing solution for 30 min.
[Ca 2+] i was measured using the fluorescent indicator, fura-2, as previously described [ 35 ] . Experiments were performed with cells in the twelfth to twentieth passage and 2-3 days post-confluency.
Addition of MTX to fura-2 -loaded BAECs, suspended in a cuvette in normal Ca 2+-containing buffer at 37°C, produced a time-dependent increase in [Ca 2+] i (Fig 1, upper panel ). Addition of either U73122 or U73343, the inactive analog, ~3 min before MTX produced a concentration-dependent inhibition of the change in [Ca 2+] i . U73343 exhibited a 3-fold greater potency compared to U73122 (Fig 1, insets ). Since U73343 has no significant effect on PLC over the concentration range employed [ 14 25 26 27 ] , these results suggest that inhibition of the MTX-induced response is independent of PLC.
Fura-2-loaded BAECs were suspended in HBS, placed in a cuvette at 37°C, and the response to extracellular application of MTX was recorded as a function of time (Fig.
Fura-2 acetoxymethyl ester (fura-2/AM) and ethidium bromide (EB) were obtained from Molecular Probes (Eugene, OR, USA).
