ProteomicsQuantitative proteomic analysis of fresh-frozen human breast tissue and tumor samples using microLC-SWATH-MS
Future improvements in the field of breast cancer prevention, diagnosis and treatment require deeper knowledge and better understanding of the molecular processes and signaling pathways that lead to the transformation of normal cells to cancer ones and the disease progression. Quantitative proteome ...

MetabolomicsAnalysis of colorectal adenocarcinoma tissue samples by DESI mass spectrometry imaging
Ex vivo colorectal adenocarcinoma samples were analysed by desorption electrospray ionisation using an Orbitrap mass spectrometer. The samples were analysed in negative mode over the m/z range 600-1000. Some of the samples presented in this dataset were analysed as part of [1]. The study makes avail...

TranscriptomicsQuantitative Expression Profiling of RNA from Formalin-Fixed, Paraffin-Embedded (FFPE)and Fresh Frozen (FF) Breast Cancer samples
Unluckily, FFPE archival methods lead to partial RNA degradation, limiting the amount of derivable information. This study aims to evaluate if the DASL gene expression assay, designed to generate reproducible data from degraded RNAs, is a reliable method to apply on RNA from FFPE tissues. In order t...

MetabolomicsGut microbiota carcinogen metabolism causes distal tissue tumours

Exposure to environmental pollutants and human microbiome composition are important predisposition factors for tumour development. Similar to drug molecules, pollutants are typically metabolised in the body, which can change their carcinogenic potential and impact tissue distribution through alte...

TranscriptomicsTranscription profiling of fresh, frozen and RNALater preserved human uterine myometrium samples
We used quantitative RNA expression profiling on the Affymetrix U133 human expression array to validate quantitative expression results obtained with the tissue preservative RNALater against snap frozen and fresh tissues as a means of routine tissue collection and temporary storage. By using split ...

ProteomicsComparison of matched formalin-fixed paraffin embedded and fresh frozen tissue reveals bias in proteomic profiles
Tissue biopsies are most commonly archived in a paraffin block following tissue fixation with formaldehyde (FFPE) or as fresh frozen tissue (FFT). While both methods preserve biological samples, little is known about how they affect the quantifiable proteome. We performed a ‘bottom-up’ proteomic ana...

MetabolomicsGlobal 13C tracing and metabolic flux analysis of intact human liver tissue ex vivo
Liver metabolism is central to human physiology and influences the pathogenesis of common metabolic diseases. Yet, our understanding of human liver metabolism remains incomplete, with much of current knowledge based on animal or cell culture models that do not fully recapitulate human physiology. He...

TranscriptomicsHigh Resolution Copy Number Analysis of Paraffin Embedded Archival Tissue Using SNP BeadArrays
High density SNP microarrays provide insight into the genomic events that occur in diseases like cancer by their capability to measure both LOH and genomic copy numbers. Where currently available methods are restricted to the use of fresh frozen tissue, we now describe the design and validation of c...

MetabolomicsPhospholipid acyl chain diversity controls the tissue-specific assembly of mitochondrial cardiolipins

Cardiolipin (CL) is a phospholipid specific for mitochondrial membranes and crucial for many core tasks of this organelle. Its side chain configurations are tissue-specific, functionally important and generated via post-biosynthetic remodeling. However, this process lacks the necessary specificit...

TranscriptomicsNext-Generation Sequencing of RNA Isolated from Paired Fresh-Frozen and Formalin-Fixed Paraffin-Embedded Samples of Human Cancer and Normal Tissue
This experiment contains the RNA-Seq samples only. Formalin-fixed, paraffin-embedded (FFPE) tissues are an invaluable resource for clinical research. However, nucleic acids extracted from FFPE tissues are fragmented and chemically modified making them challenging to use in molecular studies. We anal...
