PCBP1 and cancer: Likewise, the genes coding for igals3, i.e. a beta-galactoside-binding protein frequently overexpressed in cancers and pcbp1 that is involved in transcription and functions as an inhibitor of invasion [65] were up-regulated in transgenic non-tumour livers (ur-Tr-nT) whereas transcript expression of aars, a member of tRNA synthases and anaxa6, a calcium-dependent, phospholipid-binding protein with important roles in the tumour microenvironment and metastasis were repressed (dr-Tr-nT).
