abstract = {In the last decade, circulating nucleic acids such as
microRNAs (miRNAs) and cell-free DNA (cfDNA) have become
increasingly important in serving as potential novel
biomarkers for a variety of human diseases. If cell-free
nucleic acids are to become routinely used in diagnostics,
the difference in plasma miRNA and cfDNA levels between
healthy and diseased subjects must exceed pre-analytical and
analytical variability. Until now, few studies have
addressed the time limitations of pre-processing or explored
the potential use of long-term blood storage tubes, which
might need to be implemented in real-life diagnostics. In
this study, we analyzed the stability of four breast
cancer-associated miRNAs and two cancer-associated genes
under various storage conditions, to test their limitations
for potential application in clinical diagnostics. In two
consecutive experiments, we tested the limits of
conventional EDTA tubes, as well as long-term storage blood
collection tubes (BCTs) from four different manufacturers.
We found that circulating miRNAs are relatively stable when
stored in EDTA monovettes for up to 12 h before processing.
When stored in BCTs, circulating miRNAs and cfDNA are stable
for up to 7 days, depending on the manufacturer. Norgen
tubes were superior for cfDNA yield, while Streck tubes
performed the worst in our study with hemolysis induction.
In conclusion, plasma prepared from whole blood is suitable
for the quantification of both cf-miRNAs and cfDNA
simultaneously.},
