Figure 5From: A mechanistic role for the chromatin modulator, NAP1L1, in pancreatic neuroendocrine neoplasm proliferation and metastasesNAP1L1, p57Kip2, and menin expression in pancreatic neuroendocrine neoplasms compared to normal pancreatic tissue. NAP1L1 was increased at mRNA level (A) (Kruskal-Wallis p < 0.001) in pNEN primaries (#p < 0.01) and metastases (*p < 0.01) and expression correlated with tumor size (D) (r = 0.42, p < 0.05). In contrast, p57Kip2 mRNA was downregulated in pNEN metastases (B) (*p < 0.01). Menin was not differently expressed in pNEN in comparison to normal tissue in this sample set (C and H). Western blot analysis (E) confirmed elevated NAP1L1 protein levels (F) (*p < 0.05) and downregulated expression of p57Kip2 in pNENs (G) (*p < 0.05). Mean ± SEM.Back to article page
