POTEKP and cancer: In this study, the proteins expressed only in the CDM group were POTEKP, TAGLN3, TF, MT2A (a key protein involved in endothelial cell proliferation and migration [42]), HP, DHCR24 (a key protein involved in cell homeostasis and cholesterol biosynthesis [43]), NQO1 (a key protein involved in cellular adaptation to stress [44]), and TRAP1 (a key protein of the molecular chaperone involved in the regulation of energetic metabolism in cancer cells [45]).
