Detailed expression profiles of TNNT2, ALPP and MAG. (a) TNNT2 is a clinically used cardiac biomarker and, as expected, it shows heart-specific expression. In addition, it has been shown that TNNT2 has elevated expression in some cases of rhabdomyosarcoma, also visible from the profile. (b) ALPP had high expression in placenta and somewhat elevated expression in uterine tumors. Additionally, serous ovarian tumors showed elevated expression when compared to the mucinous ones. (c) Known neuronal marker gene MAG similarly shows an expression profile that was highly central nervous system specific.
