Direct Quantification of Cell-Free, Circulating DNA from Unpurified Plasma
Cell-free DNA (cfDNA) in body tissues or fluids is extensively investigated in clinical medicine and other research fields. In this article we provide a direct quantitative real-time PCR (qPCR) as a sensitive tool for the measurement of cfDNA from plasma without previous DNA extraction, which is known to be accompanied by a reduction of DNA yield. The primer sets were designed to amplify a 90 a...
متن کاملQuantification of circulating cell-free DNA to predict patient survival in non-small-cell lung cancer
We used computed tomography (CT) to explore the prognostic value of cell-free (cf) DNA quantification and its predictive efficacy over time after chemotherapy in non-small-cell lung cancer (NSCLC) patients. In total, 177 NSCLC patients were enrolled in a prospective biomarker trial. Consecutive paired blood collection was performed to determine cfDNA concentrations at baseline CT and throughout...
متن کاملQuantification of transplant-derived circulating cell-free DNA in absence of a donor genotype
Quantification of cell-free DNA (cfDNA) in circulating blood derived from a transplanted organ is a powerful approach to monitoring post-transplant injury. Genome transplant dynamics (GTD) quantifies donor-derived cfDNA (dd-cfDNA) by taking advantage of single-nucleotide polymorphisms (SNPs) distributed across the genome to discriminate donor and recipient DNA molecules. In its current implemen...
متن کاملCell-free circulating tumor DNA in cancer.
Cancer is a common cause of death worldwide. Despite significant advances in cancer treatments, the morbidity and mortality are still enormous. Tumor heterogeneity, especially intratumoral heterogeneity, is a significant reason underlying difficulties in tumor treatment and failure of a number of current therapeutic modalities, even of molecularly targeted therapies. The development of a virtua...
متن کاملTP53 mutations on circulating cell-free DNA
Article history: Received 6 July 2016 Accepted 6 July 2016 Available online 8 July 2016 Besides the demand for higher sensitivity, the specificity of cfDNA measurements faces even more serious challenges. Cancer-associated mutations are thought to be restricted to cancer patients. However, Fernandez-Cuesta et al. observed cfDNA TP53-mutated fragments in 11.4% of 123 matched non-cancer controls....
