Robust MicroRNA Stability in Degraded RNA Preparations from Human Tissue and Cell Samples

Abstract: BACKGROUND: RNA integrity is the essential factor that determines the accuracy of mRNA transcript measurements obtained with quantitative real-time reversetranscription PCR (RT-qPCR), but evidence is clearly lacking on whether this conclusion also applies to microRNAs (miRNAs). We evaluated this issue by comparative analysis of the dependence of miRNA and mRNA measurements on RNA integrity in renal and prostate samples, under both model and clinical conditions.

“…26 Additionally, miRNAs are more stable in degraded RNA preparations allowing for a more robust, feasible and reliable analysis. 60 A single miRNA has the ability to control a vast network of mRNA targets; therefore, the information from and potential of manipulating a few miRNA may have tremendous clinical benefit. 9 As described above, several miRNAs have been identified as being deregulated in MDS subtypes.…”

“…Az anyatejre átlagosan 10 5 µg/L, míg a vizeletre 10 2 µg/L nagyságrend jellemző [10]. A testfolyadékok-ba kijutott miRNS-ek a magas és alacsony kémhatással, a forralással és a hosszú tárolással szemben is ellenálló, rendkívül stabil molekulák [42]. Az extracellularis mi-RNS-ek élettani folyamatoknak is közreműködői lehetnek.…”

“…A sejtekből kijutásra három főbb lehetőség ismert: 1. gyulladás, illetve necrosis révén passzív kiáramlással; 2. aktív szekrécióval extracelluláris vesiculumok (például microvesiculum, apoptotikus test, exoszóma); 3. vagy makromolekuláris komplexek (például AGO [95%-ban ehhez van kötve] vagy lipoproteinek [például high density lipoprotein, azaz HDL]) segítségével. Az extracelluláris mikroRNS-ek stabilak és nagyon ellenállók külön-böző ártalmakkal szemben (magas/alacsony pH, forralás, tárolás hosszú ideig) [10]. A sejtek többsége juttat így mikroRNS-t a környezetébe, ezért az extracelluláris vesiculumok is kimutathatóak vérből, vizeletből, nyálból, anyatejből, epéből stb.…”
