1. udvinding af miRNA fra Plasma/Serum
Bemærk: For at kvantificere miRNAs korrekt, den korrekte mikroRNA isolation fra plasma/serum er et afgørende skridt. En vigtig ting at huske, især fordi der findes forskellige protokoller, er at overholde de samme arbejdsproces, mens behandling af prøverne. I denne protokol, er miRNA udvundet fra 50 µL serum. Brug ikke mere end 200 µL som denne grænse korrekte udpakningsprocessen.

Digital PCR er en relativt ny farveprøve metode til PCR, der giver mulighed for direkte absolutte kvantificering af nukleinsyrer i en prøve. Metoden besidder særlige fordele, herunder en nedsat variabilitet, en øget daglige reproducerbarhed og en overlegen følsomhed11,12. Yderligere, på grund af partitionering af prøven i ca 20.000 enkelt reaktioner og slutpunkt analyser, dPCR er mere robust over for interfererende stoffer i PCR sammenlignet med kvantitati...

Cirkulerende miRNAs er blevet identificeret som lovende markører for en række sygdomme, herunder hjerte-kar-sygdom1. MiRNAs er små, ikke-kodende enkeltstrenget RNA molekyler (ca 22 nukleotider lange) er involveret i post-transcriptional forordning via ændring af messenger RNA oversættelse og påvirke gen expression2, og frigives til omsætning i både fysiologiske og patologiske stater. Den kvantitative udtryk for specifikke miRNAs kan være knyttet til patologi, og nogle miRNAs Vis høj væv og sygdom specificitet1. I hjerte-kar-sygdomme blevet miRNAs attraktive kandidater som roman biomarkører fordi de er bemærkelsesværdigt stabilt i serum og kan nemt kvantificeres ved hjælp af PCR metode3. Den potentielle værdi af miRNAs som biomarkører for myokardieinfarkt er blevet evalueret i små undersøgelser, men en validering i store kohorter mangler2. For eksempel, miR-499 er fundet stærkt udtrykt i Myokardie musklen, og det har vist sig at være steget betydeligt i en AMI4,5,6. Yderligere, det regulerer programmeret celledød (apoptose) og differentiering af cardiomyocytes og er således involveret i flere mekanismer efter et AMI7. Bortset fra nogle små undersøgelser rapportering en trinvis værdi af miRNAs til diagnosticering af AMI og overlegenhed, overlegenhed eller ligestilling til Højfølsom hjerte troponins ikke endnu er blevet bevist i omfattende studier2,5 ,6,8. Flere prospektive studier i store kohorter behøves derfor, at vurdere den potentielle diagnostiske værdi af miRNAs. Derudover metoder miRNA bestemmelsesgrænsen skal optimeres og standardiseret bruger sammenlignelige protokoller9. Standardiseret assays kan reducere inkonsistente resultater og kan hjælpe miRNAs bliver potentielle biomarkører for rutinemæssig klinisk anvendelse, som biomarkører skal kvantificeres på en reproducerbar måde at sikre deres kliniske anvendelighed.
DPCR er for nylig blevet indført som end-point analyse. Det partitioner prøven i ca 20.000 individuelle reaktioner10. DPCR-systemet anvender derefter en matematisk Poisson statistisk analyse af fluorescerende signaler (positive og negative reaktioner), gør det muligt for en absolut kvantificering uden en standardkurve10. Når man kombinerer dPCR med fluorescerende hydrolyse sonder, muliggøres en meget specifik direkte absolutte kvantificering af miRNAs. Digital polymerase kædereaktion har vist sig for at udstille overlegne tekniske kvaliteter (herunder en nedsat variabilitet, en øget daglige reproducerbarhed, en høj grad af linearitet og en høj følsomhed) for kvantificering miRNA niveauer i de omsætning i forhold til kvantitative real-time PCR10,11. Disse overlegne tekniske kvaliteter kan bidrage til at afbøde nuværende begrænsninger på ved hjælp af cirkulerende miRNAs som biomarkører og kan føre til etablering af miRNAs som biomarkører i store multicenter kardiovaskulære kliniske forsøg og som diagnostisk metode i generelle. I en tidligere undersøgelse, vi for nylig anvendt dPCR til den absolutte kvantificering af cirkulerende miRNAs hos patienter med en AMI og kunne demonstrere superior diagnostiske potentiale i forhold til kvantificering af miRNAs af qPCR12.
I denne publikation vil vi vise, at ved hjælp af dPCR er en nøjagtig og reproducerbar metode til direkte kvantificering af cirkulerende kardiovaskulære miRNAs. Den absolutte kvantificering af miRNA niveauer i serum, ved hjælp af digital PCR, viser potentiale for brug i store multicenter kardiovaskulære kliniske forsøg. I denne publikation beskriver vi i detaljer hvordan man effektivt udføre digital PCR og hvordan man kan opdage absolutte miRNA kopi nummer i serum.

digital pcr for quantifying circulating micrornas in acute myocardial infarction and cardiovascular disease

Cirkulerende serum MicroRNA (miRNAs) har vist lovende som biomarkører for Kardiovaskulær sygdom og akut myokardieinfarkt (AMI), frigøres fra hjerte-kar-cellerne i omløb. Cirkulerende miRNAs er meget stabil og kan kvantificeres. Den kvantitative udtryk for specifikke miRNAs kan knyttes til patologi, og nogle miRNAs Vis høj væv og sygdom specificitet. Finde roman biomarkører for hjerte-kar-sygdomme er af betydning for medicinsk forskning. Ganske nylig, digital polymerase kædereaktion (dPCR) er blevet opfundet. dPCR, kombineret med fluorescerende hydrolyse sonder, giver mulighed for en specifik direkte absolutte kvantificering. dPCR udstiller overlegne tekniske kvaliteter, herunder en lav variabilitet, høj linearitet og høj følsomhed i forhold til den kvantitative Polymerasekædereaktionen (qPCR). DPCR er således en mere nøjagtig og reproducerbar metode til direkte kvantificere miRNAs, især til brug i store multicenter kardiovaskulære kliniske forsøg. I denne publikation beskriver vi, hvordan du effektivt udføre digital PCR for at vurdere den absolutte eksemplarnummer i serumprøver.

Digital PCR kombineret med fluorescerende hydrolyse sonder gør det muligt for forskere at direkte kvantificere de absolutte mængder af specifikke miRNAs i kopier/µL. Som eksemplet i dPCR er adskilt i ca 20.000 individuelle PCR reaktioner, dPCR kræver ikke teknisk replikater10.
