Ontogeny of StarD10, StarD2/PCTP, StarD7, and LPCAT1 in the developing mouse lung.
A–D, qPCR analysis of StarD10 (A), StarD2/PCTP (B), StarD7 (C), and LPCAT1 (D) expression in whole mouse lungs from stages E11.5 to adult. The mRNA level of each gene was normalized to β-actin at each time point. Note the differences in scale on the graphs for relative expression of the target genes. Data were derived from three independent litters at each time point. E, comparison of StarD2/PCTP, StarD7, StarD10, and LPCAT1 expression in freshly isolated adult mouse alveolar type II cells. StarD10 abundance was 31 times that of StarD2/PCTP and 8 times that of StarD7. Note that the level of LPCAT1 mRNA was most abundant among these four genes in the type II cells. Error bars represent S.E.
