Our results showed that the mRNA expression of PEX 6/7/10/11B/13/16 is increased in tumor tissue compared with normal tissue (PEX6, p =<0.0001; PEX7, p =<0.0001; PEX10, p=<0.0001; PEX11B, p=<0.0001; PEX13, p=<0.0001; PEX16, p=<0.0001).(Fig1A) Whereas PEX2/3/5/11A/12/19 mRNA levels were lower (PEX2, p=<0.0001; PEX3, p=<0.0001; PEX5, p=<0.0001; PEX11A, p=<0.0001; PEX12, p=<0.0001 and PEX19, p=<0.0001). Here, PEX13 is linked to neoplasm.
