“…Although previous studies showed the feasibility of detecting mRNAs and monitoring the transportation of RNAs in cells, the procedure for delivery of the molecular beacons through microinjection or by liposome delivery has made it difficult to apply this technology into broad research areas or into a routine clinical procedure (9)(10)(11)(12). A recent study showed that it is feasible to transfect a molecular beacon into living cells to detect doxorubicin-induced activation of p21 gene expression (13).…”

“…The feasibility of detecting intracellular mRNA has been examined in several laboratories (9)(10)(11)(12)(13). It has been shown that molecular beacons were able to visualize mRNA molecules in several human and animal cell lines after introducing into cells through microinjection or liposome delivery (9)(10)(11)14).…”

“…Im Zellinnern werden MBs typischerweise in 45 min abgebaut, was sich in einem starken Anstieg der Fluoreszenz zu erkennen gibt. [14,55] Mit dem Ziel, die zytoplasmatische Stabilität von MBs zu verbessern, wurden modifizierte DNA-Basen in MBs eingebaut, darunter 2'-O-Methylderivate, [110][111][112] Phosphorthioatderivate [113,114] und Peptidnucleinsäure(PNA)-Basen. [115,116,141] Die 2'-O-Methyl-modifizierten MBs zeigen gute Nucleaseresistenz gegen intrazelluläre Spaltung und werden von RNase H nicht erkannt.…”

Mit diesen Modifikationen erhalten die MBs zusätzliche Eigenschaften wie Nucleaseresistenz, bessere Hybridisierungsaffinität und minimierte unspezifische Proteinbindung.…”

“…To overcome the biostability problem, MBs have been synthesized with nuclease-resistant backbone chemistries [2,[24][25][26][27] , including 2′-O-methyl-RNA bases [20,26] , locked nucleic acid (LNA) [26,27] , and phosphorothioate modification [24] . But these backbone-modified MBs still have some shortcomings when used in nucleic acid detection in living cells.…”
