Eng, Acvrl1, and Ptpn14 gene expression are highly correlated in normal mouse lung tissues. RNA extracted from a panel of 69 wild type healthy mouse lungs from an F1 inter-specific mouse backcross between Mus spretus and Mus musculus FVB/Ola, was subjected to TAQMAN qRT-PCR analysis with five probes, Eng, Acvrl1, Ptpn14, Gus, and Gapdh. (A–C) show pair-wise correlations for expression of the two probes indicated in each of the 69 samples. Eng, Acvrl1, and Ptpn14, expression are normalized against Gapdh. The data showed a similar strong correlation when normalized against Gus (not shown). Non-parametric Spearman Rank correlations shown were calculated in R.
