CNA = Circulating Nucleic Acids

Most of the DNA and RNA in the body is located within cells, but a
small amount of nucleic acids can also be found circulating freely in
the blood. These DNA, RNA and small RNA molecules are thought to come
from dying cells that release their contents into the blood as they
break down. The term "Circulating Nucleic Acids = CNA" refers to
segments of DNA or RNA found in the bloodstream.

CNAs offers a non-invasive approach to a wide range in diagnostics of
clinical disorders that will allow the basic information necessary not
only for use in predictive medicine but also for direct use in acute
medicine. Further free CNAs offer unique opportunities for early
diagnosis of clinical conditions, e.g. in early cancer detection.

Although DNA was first demonstrated in human blood from healthy
donors, pregnant women and clinical patients in 1948, the structure of
DNA was still to be determined as was the elucidation of its role as
the basis of the gene. Consequently, no interest was shown in the
presence of DNA in the circulatory system until high DNA levels were
demonstrated in the blood of patients with systemic lupus
erythematosus. Similar observations were also made in acute medicine,
diabetes, oncology and fetal medicine. The presence of DNA and RNA in
plasma of patients has been recognised since the 1970s.

A range of markers have been proposed for the identification of a
particular cancer, though there is frequent conflict in the literature
as to the effectiveness of particular probes. However, recently,
hypermethylated CpG in the promotor region of tumour suppressor genes
has been suggested to trigger local gene silencing. Aberrant
methylation of the p26 tumour suppressor gene was the first to be
detected in liver, breast and lung cancer.

Nucleic acids can be found in small amounts in healthy and diseased
human plasma/serum. Higher concentrations of DNA are present in the
plasma of cancer patients sharing some characteristics with DNA of
tumor cells. Together with decreased strand stability, the presence of
specific oncogene or tumor-suppressor gene mutations, microsatellite
alterations, Ig rearrangements and hypermethylation of several genes
may be detected. Moreover, tumor-related mRNA has been found
circulating in the plasma/serum.

The results obtained in many different cancers have opened a new
research area indicating that circulating nucleic acids might
eventually be used for the development of noninvasive diagnostic,
prognostic and follow-up tests for cancer.
