Figure 8. Real time reverse transcriptase polymerase chain reaction mucin 5AC glycoprotein messenger RNA expression changes with diquafosol application in the Sod1^-/- mice and wild type (WT) mice. Note the significant increase in muc 5Ac mRNA expression in both WT and the Sod1^-/- mice with 2 weeks of diquafosol sodium treatment. * represents p < 0.01.
