Project description:Gene expression profiling of NSCLC tumors with distinct PAEP expression suggested several pathways, which might be involved in the regulation of PAEP/glycodelin expression.
Project description:A custom microarray was used to measure the gene expression of NSCLC tumors. This represents a subset of samples which also have matched DNA copy number profiles from array CGH experiments 49 microdissected NSCLC tumor samples

Project description:The gene expression profiles were identified in breast cancer tumors with different level of FAK three tumors with low FAK expression identified by IHC and 3 tumors with high FAK expression. 2 triple-negative with low and one triple negative with high FAK expression was among these 6 samples
Project description:Whole genome tiling path array CGH was used to measure the copy number profiles of 271 NSCLC tumors 271 microdissected NSCLC tumors
Project description:Genomic changes in low and highly metastatic A549 cells were analyzed by 500K SNP arrays. A large number of genomic alterations were present in A549 cells but no significant differences were observed between the low or highly metastatic A549 cell lines. We generated a NSCLC line with highly increased propensity to form tumor nodules in murine lungs after intravenous injections. Extravasation and growth at a distant site are important parts of the metastatic process and we regarded these as a surrogate marker for in vivo aggressiveness and potential metastatic capability. A549 lung asdenocarcimona cell line with initially low metastatic potential was used for this purpose; these cells formed multiple small nodules in NOD/SCID mice after first i.v.-injection, round 1 (R1). Removal of tumor nodules from the lungs and subsequent re-injection led to a rapid increase in metastatic capacity. A highly aggressive phenotype which was stable over time was evident after three rounds (R3) of in vivo selection for the A549 cell line.
