TYMP and neoplasm: The location of TP expression varies between tumour type and grade and has been reported to be highly expressed in tumour cells (O’Brien et al, 1996), the invasive part or the tumour (Kubota et al, 1997; Yoshikawa et al, 1999; Hayashi et al, 2008) or in the tumour stromal cells (Nagaoka et al, 1998; Sakamoto et al, 1999; Liakakos et al, 2006; Ruckhäberle et al, 2010).
