Figure 2. Total mRNA expression in aging liver.
(A) mRNA content in liver tissue was quantified by purification with oligo-dT magnetic beads and normalized to input DNA. (B) Left panels: representative images of oligo-dT immuno-FISH staining of liver sections. Nuclei were stained with DAPI (blue). E-cadherin staining (red) highlights cellular membranes. Intracellular mRNA was detected using Cy3-oligo-dT probes (green). Right panel: quantification of polyA+ signal. Means and standard deviations are shown. (*) p<0.01; (**) p≤0.05.
