COMPARISON OF TRIPLE-NEGATIVE BREAST CANCER MOLECULAR SUBTYPING USING RNA FROM MATCHED FRESH-FROZEN VERSUS FORMALIN-FIXED PARAFFIN-EMBEDDED TISSUE
Triple negative breast cancer (TNBC) is a heterogeneous disease that lacks unifying molecular alterations that can guide therapy decisions. We previously identified distinct molecular subtypes of TNBC (TNBCtype) using gene expression data generated on a microarray platform using frozen tumor specime[r]

Integration of RNA-Seq data with heterogeneous microarray data for breast cancer profiling
Nowadays, many public repositories containing large microarray gene expression datasets are available. However, the problem lies in the fact that microarray technology are less powerful and accurate than more recent Next Generation Sequencing technologies, such as RNA-Seq.
BART: Bioinformatics array research tool
Microarray experiments comprise more than half of all series in the Gene Expression Omnibus (GEO). However, downloading and analyzing raw or semi-processed microarray data from GEO is not intuitive and requires manual error-prone analysis and a bioinformatics background.
