MicroRNAs (miRNAs) are small non-coding RNAs that repress gene expression at the post transcriptional level via an antisense RNA-RNA interaction. Generally, miRNAs derived from snap frozen or fresh samples are used for array based profiling. Since tissues in most pathology departments are available ...

The Formalin-Fixed Paraffin-Embedded (FFPE) samples on selected breast cancer subtypes (ER+/Her2-, ER+/Her2+, ER-/Her2+, and ER-/Her2-) and their paired fresh fine needle aspirated biopsies (FNA) were investigated. The cases represented different subtypes of breast cancers based on their clinical re...

In an effort to identify biomarkers of recurrence, we have performed global RNA-sequencing on 106 formalin-fixed, paraffin-embedded (FFPE) prostatectomy samples from 100 patients at three independent sites, and identified a new set of biomarkers of biochemical recurrence composed of a 24-gene panel....

The ability to accurately quantify proteins in formalin-fixed paraffin-embedded (FFPE) tissues using targeted mass spectrometry opens exciting perspectives for biomarker discovery. We have developed and evaluated a selected reaction monitoring (SRM) assay for the human receptor tyrosine-protein kina...

Current prognostic factors are poor at identifying patients at risk of disease recurrence following surgery for stage II colon cancer. Here we describe a DNA microarray based prognostic assay using clinically relevant formalin fixed paraffin embedded (FFPE) samples.

This SuperSeries is composed of the following subset Series: GSE32488: Expression profiling of formalin-fixed, paraffin-embedded (FFPE) breast cancer metastases of the lymph node and autopsy tissues [DASL HT-12 samples] GSE32489: Expression profiling of formalin-fixed, paraffin-embedded (FFPE) breas...

A study to evaluate techniques for repairing DNA from formalin-fixed paraffin-embedded (FFPE) tissue samples by direct comparison of FFPE DNA repair methods prior to analysis on genome-wide methylation array to matched fresh frozen (FF) tissues. Formalin-fixed paraffin-embedded tissue from three col...

Triple-negative breast cancer (TNBC) presents significant challenges to female

health owing to the lack of therapeutic targets and its poor prognosis. In recent

years, in the field of molecular pathology, there has been a growing focus on the

role of intra-tumoral microbial comm...

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...
