Representative novel reproductive tract-specific human (a) and mouse (b) genes without a reported mouse model. The listed genes were identified through our studies as reproductive tract-specific in both humans and mice. The digital PCR (heatmap) depicts the average transcripts per million (TPM) value per tissue per gene from the indicated human and mouse RNA-seq datasets as processed in parallel through our bioinformatics pipeline. The data was obtained from 264 published and newly acquired datasets. White = 0 TPM, Black ≥ 30 TPM. The expression profile of the human and mouse housekeeping genes, GAPDH and Eif3l, is included as reference. For data obtained from published datasets, superscript values succeeding the sample names reference the publications as follows: 1 (Djureinovic et al. ; Fagerberg et al. ), 2 (Guo et al. ), 3 (Zhu et al. ), 4 (Kumar et al. ), 5 (Browne et al. ), 6 (Consortium et al. ), 7 (Helsel et al. ), 8 (da Cruz et al. ), and 9 (Zimmermann et al. ).
