Figure 2From: Comparison of PCR-based detection of chromogranin A mRNA with traditional histological lymph node staging of small intestinal neuroendocrine neoplasiaChromogranin A transcript expression level of and degree of lymph node involvement by tumor. The mean (and SEM) expression level of 3 different CgA primers, namely CHGA Hs00900369_s1 (2a), CHGA Hs00900371_s1 (2b), and CHGA Hs00900373_s1 (2c) is shown. The expression level of CgA differs significantly in all three primers (pā<ā.0001, pā=ā.0004 and pā<ā.0001 respectively). Post-hoc testing shows significantly higher expression in the ātotal replacementā group than in the ānilā or āminimal tumorā groups for all primers. In addition, post hoc tests show a significant difference between āNilā and āpartial replacementā in the primer shown in 2c.Back to article page
