Characterization of AECII gene expression of proliferation markers, proinflammatory cytokines, TGF-β1, and receptors. A, transcriptional levels of proliferation marker, p15, p21, and Ki67 mRNAs in isolated AECII from telomerase wild type and deficient mouse lungs by quantitative PCR. B, SPC protein expression in isolated AECII measured by Western blotting and analyzed with semiquantification. C, transcriptional levels of IL and TGF-β family mRNAs in isolated AECII from G2 TERC-null mice lungs. D, transcriptional levels of IL and TGF-β family mRNAs in isolated AECII from G3 TERT-null mice lungs. Error bars, S.E.; N.S, not significant.
