c-fos mRNA and gastrin releasling peptide receptor antagonists. (Top) The ability of 100 nM (d-Phe6, β-Ala11, Phe13, Nle14)bombesin-(6–14) (a,b) or 10 nM bombesin (c,d) to increase c-fos mRNA was determined in the absence (b,d) or presence (a,c) of 1 μM BW2258U89. (Bottom) Ethidium bromide staining. This experiment is representative of three others.
