Diurnal Variations of Human Circulating Cell-Free Micro-RNA
A 24-hour light and dark cycle-dependent rhythmicity pervades physiological processes in virtually all living organisms including humans. These regular oscillations are caused by external cues to endogenous, independent biological time-keeping systems (clocks). The rhythm is reflected by gene expression that varies in a circadian and specific fashion in different organs and tissues and is regul...
متن کاملCell - free DNA: بیومارکر نوین تشخیص آزمایشگاهی
به انواع مختلف اسیدهای نوکلئیک آزاد در پلاسما شامل قطعات DNA ژنومی،DNA میتوکندریایی، DNA و mRNA های ویروسی و همچنین انواع miRNA اصطلاحا Cell–free nucleic acid گفته می شود. بخش مهمی از این اسیدهای نوکلئیک آزاد در پلاسما را Cell–free DNA (cfDNA) تشکیل می دهد. cfDNA به صورت قطعاتی با وزن مولکولی حدود KB 21-0.18 در سرم یا پلاسمای افراد سالم و افراد مبتلا به بسیاری از بیماری ها قابل تشخیص هستند. ...
متن کاملchimeric external control to quantify cell free dna in plasma samples by real time pcr
background: dna isolation procedure can significantly influence the quantification of dna by real time pcr specially when cell free dna (cfdna) is the subject. to assess the extraction efficiency, linearity of the extraction yield, presence of co-purified inhibitors and to avoid problems with fragment size relevant to cfdna, development of appropriate external dna control (edc) is challenging. ...
متن کاملPlasma Cell-Free DNA in Paediatric Lymphomas
BACKGROUND Extracellular circulating DNA (cfDNA) can be found in small amounts in plasma of healthy individuals. Increased levels of cfDNA have been reported in patients with cancer of breast, cervix, colon, liver and it was shown that cfDNA can originate from both tumour and non-tumour cells. OBJECTIVES Levels of cfDNA of a large series of children with lymphoma were evaluated and analyzed i...
متن کاملOptimized Library Prep for Cell-Free DNA from Human Plasma
Researchers and clinicians are increasingly interested in using Next Generation Sequencing (NGS) analysis of cell-free DNA (cfDNA) found in plasma (the cell-free fraction of anticoagulated blood) for biomarker discovery and diagnostic applications. Two areas of specific interest are non-invasive prenatal diagnostics (1-6) and monitoring efficacy of treatment in cancer patients (7-20). Many rece...
