PACAP-27 and VEGF mRNA. (Top) VEGF mRNA was determined by Northern blot as a function of time after the addition of 100 nM PACAP-27 to NCI-H1299 cells. (Bottom) Equal amounts of RNA were loaded onto the gels based on ethidium bromide staining of the 28S and 18S rRNA. This experiment is representative of two others.
