Core-shell Structured Chitosan-polyethylenimine Nanoparticles for Gene Delivery: Improved Stability, Cellular Uptake, and Transfection Efficiency

Sandrine Gerber, Perrine Agnes Edith Robin, Laura Camille Louise Nicolle

Gene therapy emerged as a promising treatment option for acquired and inherited diseases. The delivery of nucleic acids relies on vectors that condense and encapsulate their cargo. Especially non-viral gene delivery systems are of increasing interest. Howe ...

Comprehensive analysis of the circadian nuclear and cytoplasmic transcriptome in mouse liver

Felix Naef, Cédric Gobet, Benjamin Dieter Weger, Clémence Yumie Syloun Hurni

In eukaryotes, RNA is synthesised in the nucleus, spliced, and exported to the cytoplasm where it is translated and finally degraded. Any of these steps could be subject to temporal regulation during the circadian cycle, resulting in daily fluctuations of ...

Endogenous RNAs Modulate MicroRNA Sorting to Exosomes and Transfer to Acceptor Cells

Michele De Palma, Mario Leonardo Squadrito, Claudio Maderna, Frederic Burdet

MicroRNA (miRNA) transfer via exosomes may mediate cell-to-cell communication. Interestingly, specific miRNAs are enriched in exosomes in a cell-type-dependent fashion. However, the mechanisms whereby miRNAs are sorted to exosomes and the significance of m ...

Detection of RNAP-DNA complexes using solid state nanopores

Aleksandra Radenovic, Michael Graf, Camille Alice Raillon

Transcription is the first step in gene expression where DNA is copied into RNA. It is extensively studied at the bulk level especially the regulation mechanism, which in cancerous cells is impaired. We were interested in studying E. coli RNAP enzyme at th ...

Nanopore sensing of single molecules application to RNAP-DNA complexes, fabrication of graphene-nanopore devices and translocation algorithm analysis

Camille Alice Raillon

Nanopore sensing is a single-molecule technique that allows to probe the nano-bio-world with accuracy. It is a non-invasive technique, which means that the molecule of interest does not need to be labeled to be detected by the nanopore. Most of the studies ...

The telomere-binding protein Tbf1 demarcates snoRNA gene promoters in Saccharomyces cerevisiae

Felix Naef, Jacques Rougemont, Enrico Guarnera

Small nucleolar RNAs (snoRNAs) play a key role in ribosomal RNA biogenesis, yet factors controlling their expression are unknown. We found that the majority of Saccharomyces snoRNA promoters display an aRCCCTaa sequence motif at the upstream border of a TA ...

TERRA: telomeric repeat-containing RNA

Joachim Lingner

Telomeres, the physical ends of eukaryotic chromosomes, consist of tandem arrays of short DNA repeats and a large set of specialized proteins. A recent analysis has identified telomeric repeat-containing RNA ( TERRA), a large non-coding RNA in animals and ...

Protein-binding microarrays: probing disease markers at the interface of proteomics and genomics

Jan Kerschgens, Tanja Egener-Kuhn, Nicolas Mermod

DNA-binding proteins mediate a variety of crucial molecular functions, such as transcriptional regulation and chromosome maintenance, replication and repair, which in turn control cell division and differentiation. The roles of these proteins in disease ar ...

The RNA degradosome: life in the fast lane of adaptive molecular evolution

In Escherichia coli, the multi-enzyme RNA degradosome contributes to the global, posttranscriptional regulation of gene expression. The degradosome components are recognized through natively unstructured "microdomains" comprising as few as 15-40 amino acid ...

Short, synthetic and selectively 13C-labeled RNA sequences for the NMR structure determination of protein–RNA complexes

Luc Reymond, Philipp Wenter

We report an optimized synthesis of all canonical 2'-O-TOM protected ribonucleoside phosphoramidites and solid supports containing [13C5]-labeled ribose moieties, their sequence-specific introduction into very short RNA sequences and their use for the stru ...
