PDLIM7 and mucinous neoplasm: When comparisons between LMP cases and carcinomas were made for serous and mucinous types separately, statistically significant differences were recorded for both MCM-2 (Mann–Whitney U-test, P<0.0001 for serous and P=0.0070 for mucinous tumours) and MCM-5 protein expression (Mann–Whitney U-test, P<0.0001 for serous and P=0.0020 for mucinous tumours; Table 2).
