Methods for Determining Hepatocellular Carcinoma Subtype and Detecting Hepatic Cancer Stem Cells
Posted Jul 31 2007 5:00pm
Description of Invention: Hepatocellular carcinoma (HCC) is the third leading cause of cancer death worldwide, and it is very heterogeneous in terms of its clinical presentation as well as genomic and transcriptomic patterns. HCC can originate from both adult hepatocytes and hepatic progenitor cells. The extent of progenitor cell activation and the direction of differentiation are correlated with the severity of the disease. HCC patient variability indicates that HCC comprises several biologically distinct subtypes. This heterogeneity and the lack of appropriate biomarkers have hampered patient prognosis and treatment stratification.
Available for licensing are microRNA biomarkers that are associated with four HCC subtypes: hepatic stem cell-like, bile duct epithelium-like, hepatocytic progenitor-like, and mature hepatocyte-like. One unique profile is associated with HCC with features of liver stem cells and poor patient prognosis. It has both diagnostic and therapeutic value in the management of HCC patients.
A diagnostic assay where HCC treatment can be individualized according to patient HCC subtype
An assay for HCC to prognose patient survival
Therapeutic compositions that target subtype specific HCC
Development Status: The technology is currently in the pre-clinical stage of development.
