Verfahren zur Diagnose von frühen Krebsvorstufen der Leber und Niere

摘要

The invention relates to a method for diagnosing preliminary stages of cancer of the liver and kidney. Detection of the presence of insulin receptor substrate (IRS-1) in glycogenolytic foci (GSF) and/or mixed cellular foci (MCF) in a tissue sample or from the extracted nucleinic acid is assisted by the bonding of a specific reagent, for example an antibody or a nucleinic acid probe, and the display of the formed complex. In addition, the invention provides a method for testing substances which are suspected to cause liver or kidney cancer.
