Abstract Investigations into the fate of small interfering RNA (siRNA) after transfection may unravel new ways to improve RNA interference (RNAi) efficiency. Because intracellular degradation of RNA may prevent reliable observation of fluorescence-labeled siRNA, new tools for fluorescence microscopy are warranted to cover the considerable duration of the RNAi effect. Here, the characterization and application of new fluorescence resonance energy transfer (FRET) dye pairs for sensing the integrity of duplex siRNA is reported, which allows an assessment of the degradation status of an siRNA cell population by live cell imaging. A panel of high-yield fluorescent dyes has been investigated for their suitability as FRET pairs for the investigation of RNA inside the cell. Nine dyes in 13 FRET pairs were evaluated based on the performance in assays of photostability, cross-excitation, bleed-through, as well as on quantified changes of fluorescence as a consequence of, e.g., RNA strand hybridization and pH variation. The Atto488/Atto590 FRET pair has been applied to live cell imaging, and has revealed first aspects of unusual trafficking of intact siRNA. A time-lapse study showed highly dynamic movement of siRNA in large perinuclear structures. These and the resulting optimized FRET labeled siRNA are expected to have significant impact on future observations of labeled RNAs in living cells.

Abstract Objectives In frame of a study to characterize the interaction of human macrophage-like cells with pathogenic corynebacteria, Corynebacterium diphtheriae and Corynebacterium ulcerans, live cell imaging experiments were carried out and time lapse fluorescence microscopy videos were generated, which are presented here. Data description The time lapse fluorescence microscopy data revealed new insights in the interaction of corynebacteria with human macrophage-like THP-1 cells. In contrast to uninfected cells and infections with non-pathogenic C. glutamicum used as a control, pathogenic C. diphtheriae and C. ulcerans showed highly detrimental effects towards human cells and induction of cell death of macrophages.
