Feasibility of Developing Reliable Gene Expression Modules from FFPE Derived RNA Profiled on Affymetrix Arrays

(Submitter supplied) This SuperSeries is composed of the SubSeries listed below. The reliability of differential expression analysis on FFPE expression profiles from Affymetrix arrays is questionable, due to the wide range of percent-present values reported in studies which profiled FFPE samples on Affymetrix arrays. Moreover the validity of externally defined gene-modules in FFPE microarray expression profiles is unknown. more...

Fresh-Frozen samples profiled on HG-U133plus2 array with Affymetrix's GeneChip® 3' IVT Express kit

(Submitter supplied) The reliability of differential expression analysis on FFPE expression profiles from Affymetrix arrays is questionable, due to the wide range of percent-present values reported in studies which profiled FFPE samples on Affymetrix arrays. Moreover the validity of externally defined gene-modules in FFPE microarray expression profiles is unknown. Using eight breast cancer tumors with available frozen and FFPE samples, five sample-matched data sets were generated from different combination of Affymetrix arrays, amplification-and-labeling kit and sample preservation method. more...
