Primagen to Provide Quest Diagnostics With Retina Mitox Mitochondrial(TM) DNA Blood Test for Scientific Research Use

Posted on: Tuesday, 13 July 2004, 06:00 CDT

AMSTERDAM, July 13 /PRNewswire/ -- Primagen Holding B.V. (http://www.primagen.com/), a provider of molecular diagnostic tests for infectious diseases, AIDS and cancer, announced that it will provide Quest Diagnostics Incorporated reagents and kits to perform its proprietary Retina(TM) Mitox(TM) test to quantify human mitochondrial DNA in blood cells for studies by government, academic and clinical research organizations.

Mitochondria, the key energy-generating organelles in the cell, are unique in having their own replication enzyme, DNA polymerase gamma. Nucleoside reverse transcriptase inhibitors (NRTIs), a category of antiviral drugs used against HIV, affects the function of this enzyme, leading to the depletion of mitochondrial DNA. Such inhibition of the mitochondrial DNA synthesis is the mechanism of several known toxicities of nucleoside analogues: myopathy, cardiomyopathy, peripheral neuropathy, pancreatitis, lactic acidosis, hepatic steatosis and lipodystrophy. NRTI-related toxicities present a significant problem in the treatment of patients infected with HIV-1. To help alleviate this problem, Primagen has developed a molecular test to assess the mitochondrial DNA content of cells from blood or tissue. Through the new agreement, Quest Diagnostics will provide testing on a limited basis only to research organizations interested in studying the test's potential impact.

"We look forward to the relationship with Quest Diagnostics," said Bob van Gemen, CEO of Primagen. "This relationship provides an exciting opportunity to expand the clinical research effort with high quality Mitox(TM) diagnostic service and underscores our efforts to show the added value of mitochondrial DNA testing assessing adverse effects of antiviral treatment."
