Description
Microarray expression profiling has currently failed to provide a consistent classification for human prostate cancer. Such classifications are important because they provide a framework for the identification of new biomarkers of clinical behavior and for the development of targeted therapies. We hypothesize that previous studies have been unsuccessful because of their failure to take into account the well documented occurrence of prostate cancer multifocality and genetic heterogeneity. We have invented a novel method for collecting whole RNALater preserved research slices from prostatectomy specimens that, for the first time, allows the mapping of multifocality and of genetic heterogeneity in prostate cancer to be integrated with the selection of samples for expression microarray analysis. For each specimen we will construct a map of the regions of cancer and of their ERG gene rearrangement status from whole mount formalin fixed sections immediately juxtaposed to the research slice. Only foci of cancers containing a homogeneous pattern of ERG gene alteration will be selected for study. A pilot study has already demonstrated the feasibility of this approach, and provides initial evidence that cancers may be stratified into at least two prognostically distinct categories. Novel biomarkers defining distinct prostate cancer categories will be verified and validated in future studies linked to clinical trials.

Description
Background: Inter-patient prostate cancer (PrCa) heterogeneity results in highly variable patient outcomes. Multi-purpose biomarkers to dissect this heterogeneity are urgently required to improve treatment and accelerate drug development in PrCa. Circulating biomarkers are most practical for evaluating this disease. We pursued the analytical validation and clinical qualification of blood mRNA expression arrays.

Description
OBJECTIVE: Previous expression microarray analyses have failed to take into consideration the genetic heterogeneity and complex patterns of ERG gene alteration frequently found in cancerous prostates. The objective of this study is for the first time, to integrate the mapping of ERG gene alterations with the collection of expression microarray data.
Publication Title
Integration of ERG gene mapping and gene-expression profiling identifies distinct categories of human prostate cancer.

Description
Actomyosin contractility regulates cell morphology and movement. The objective of this study was to identify whether actomyosin contractility regulates gene expression in tumour cells and whether such genes are involved in cell morphology and movement. Gene expression analysis was carried out on highly contractile melanoma cell line A375M2 plated on a deformable collagen matrix under conditions where actomyosin contractility could be altered following treatment with blebbistatin, a direct inhibitor of myosin II, or Rho-kinase inhibitors Y27632 or H1152 that interfere with signalling to myosin II.

Description
Objective: In order to personalise standard therapies based on molecular profiles, we previously classified colorectal cancers (CRCs) into five distinct subtypes (CRCAssigner) and later into four consensus molecular subtypes (CMS) with different prognoses and treatment responses. For clinical application, here we developed a low-cost multiplex biomarker assay.

Description
Pericytes are integral components of the tissue vasculature and have essential functions in tumour angiogenesis. Endosialin (CD248) is a type I transmembrane glycoprotein highly expressed on pericytes in the tumour vasculature of most solid tumours, however it is low or negligibly expressed on normal tissue pericytes. Experiments using wild-type and endosialin-knockout mice has revealed that stromal endosialin expression facilitates intravasation of tumor cells from the primary tumor into the circulation, thereby promoting metastatic dissemination.
