  • Clinicopathological significance of Nup88 expression in patients with colorectal cancer

    • Objective: The nucleoporin Nup88 is overexpressed in a series of human malignancies, however, its clinicopathological significance has not been studied. Our aims were to analyze Nup88 expression in normal mucosa, primary tumors and metastases from colorectal cancer patients and further to identify relationships of Nup88 expression with clinicopathological and other factors.Materials and Methods: Using immunohistochemistry, we investigated Nup88 expression in 198 primary colorectal tumors, 96 normal mucosa samples and 35 lymph node metastases.Results: The results showed that the intensity of Nup88 expression increased from the normal mucosa to the primary tumors (p < 0.0001) and tended to increase from the primary tumors to the metastases (p = 0.15). Both primary tumors and metastases presented stronger expression in the invasive margin and vascular-invaded areas. Nup88 expression was positively related to distal tumor location (p = 0.01), infiltrative growth pattern (p = 0.04) and higher proliferative activity (p = 0.04) and reversely to the grade of differentiation (p = 0.02) and apoptosis (p = 0.049). Strong expression of Nup88 predicted a worse outcome in the patients with distal tumors during the follow-up period of up to 3 years (p = 0.02).Conclusions: It seems that overexpression of Nup88 was involved in the tumorigenesis and aggressiveness of colorectal cancers, and Nup88 may be used as a prognostic factor in patients with distal tumors.

  • Microsatellite instability and MBD4 mutation in unselected colorectal cancer
  • 2003
  • Ingår i: Anticancer Research. - 0250-7005 .- 1791-7530. ; 23:4, s. 3569-3574
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: We investigated the prognostic significance of microsatellite instability (MSI) and the association with clinicopathological factors in colorectal cancer, and further identified MBD4 mutations and their clinicopathological significance.PATIENTS AND METHODS: MSI was analyzed in 201 colorectal cancers. Sequencing analysis of MBD4 was performed in 26 MSI and 28 microsatellite stable (MSS) tumors.RESULTS: Twenty-seven tumors (13.4%) were MSI but did not correlate with improved survival. MSI was significantly correlated with proximal colon tumors (p < 0.001), poor differentiation or mucinous type (p = 0.005) and multiple tumors (p = 0.04). MBD4 mutations were found in 15% MSI but not in MSS tumors. The mutated cases showed female overrepresentation, proximal site and poorly-differentiated/mucinous type.CONCLUSION: MSI was not correlated with survival, but shared other features associated with MSI in colorectal cancer as demonstrated by others. The clinicopathological variables associated with the MBD4 mutations were probably the reflection of MSI features.
