Epithelial-mesenchymal transition in human prostate cancer demonstrates enhanced immune evasion marked by IDO1 expression
Cancer invasion and metastasis are driven by epithelial-to-mesenchymal transition (EMT). This study identifies an important link between EMT and immune evasion in prostate cancer patients.
Overexpression of miR-221 and miR-222 in the cancer stroma is associated with malignant potential in colorectal cancer
In this study the authors used laser capture microdissection to investigate the role of stromal miRNA in patients with metastatic cancer, aiming to identify those miRNAs present in the stroma that may contribute to metastases.
Laser Capture Microdissection (LCM) - A Strategy for Success
Micro-sampling by laser capture microdissection is a powerful tool allowing specific analysis from whole tissues, in heterogeneous microenvironments such as tumours, where less well represented target cells are dwarfed by tissue stroma and other cell types. Whilst the application is potentially powerful for target discovery and mechanistic understanding, the process is notoriously difficult, particularly in clinical specimens. Our Laser Capture Microdissection team has evaluated the findings from all the studies run in our GCLP-accredited labs and devised a strategy for LCM studies maximising the potential of success and giving the sponsor control over go/no go decisions.
Stratification of Patients using Gene Expression Analysis of Laser Capture Microdissected (LCM) Tissue and Histology/IHC
This procedure could help stratify patients where pre-treatment could be avoided, these patients may then benefit from advanced surgery or alternative treatment options and prevent unnecessary toxicities.
Laser Capture Microdissection for Gene Expression Analysis in Distinct Cell Populations
Knowledge in early phase cancer development to provide understanding of the mechanism of action of oncogenic mutations is constantly growing. A recent study carried out by Mo et al has highlighted several interesting results.
