PCR NEWS - July 2011 - focus on circulating microRNAs ----------------------------------------------------------------------- Dear researcher, dear Gene Quantification page reader, Our newsletter informs about the latest news in quantitative real-time PCR (qPCR and qRT-PCR), which are compiled and summarised on the Gene Quantification homepage. The focus of this newsletter issue is: - Update - circulating nucleic acids - focus on microRNA - http://CNA.gene-quantification.info - Recorded qPCR 2011 Event =3D> qPCR 2011 eConference - http://eConference.qPCR2011.net - US qPCR Symposium in Santa Clara, CA - 1st-4th November 2011 - http://EVENTS.gene-quantification.info - MIQE qPCR APP for iPhone, iPad and iPod - iOS Universal - http://MIQE.gene-quantification.info ---------------------------------------------------------------------------= -- Circulating Nucleic Acids (CNA) - Introduction http://CNA.gene-quantification.info 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 =3DCNA" 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 - see here =3D> http://CNA.gene-quantification.info ---------------------------------------------------------------------------= -- new CNA microRNA papers: Extracellular microRNA: A new source of biomarkers.
