Project description:Reports on common mutations in neuroendocrine tumors (NET) are rare and clonality of NET metastases has not been investigated in this tumor entity yet. We selected a NET and a the corresponding lymph node and liver metastases as well as the derivative cell lines to screen for somatic mutations in the primary NET and to track the fate of genetic changes (by Affymetrix SNP 6.0 micorarray and targeted resequencing by 454 GS FLX) and during metastasis and in vitro progression. using Affymetrix SNP 6.0 Arrays.

Affymetrix SNP 6.0 arrays were performed according to the manufacturer's directions on DNA extracted from cryo material or cell lines. Copy number analysis of Affymetrix SNP 6.0 arrays was performed for 4 samples. 60 samples from HapMap database were used as references for copy number inference.
