In previous studies, wide tissue distribution of MTUS1 mRNA was reported by quantitative RT-PCR and some new studies examined the down-regulation of MTUS1 in tumors such as ovarian cancer, pancreatic carcinoma or breast cancer, but to date nothing is known about the localisation of MTUS1 within these tissues (3,5,13,14,27). This evidence concerns the gene MTUS1 and exocrine pancreatic carcinoma.
