Krüppel‐associated box (KRAB)‐containing zinc finger proteins (KZFPs) are encoded in the hundreds by the genomes of higher vertebrates, and many act with the heterochromatin‐inducing KAP1 as repressors of transposable elements (TEs) during early embryogene ...

Quantitative single cell dynamics of signaling and transcriptional response in mammalian cells

Onur Tidin

Cells live in ever-changing environments, thereby facing a variety of dynamic environmental signals. Environmental stimuli elicit intracellular responses through signaling pathways, which converge on transcriptional activation or repression of target genes ...

Circadian clock- and feeding-dependent regulation of translation initiation and elongation in the liver

Cédric Gobet

Circadian rhythms allow organisms to anticipate and adapt to periodic environmental changes related to the day-night cycle. These rhythms originate from a genetic network ticking in almost every cell of our body and the coordination between different organ ...

RNA velocity of single cells

Gioele La Manno

RNA abundance is a powerful indicator of the state of individual cells. Single-cell RNA sequencing can reveal RNA abundance with high quantitative accuracy, sensitivity and throughput 1 . However, this approach captures only a static snapshot at a point in ...

Superparamagnetic iron oxide nanoparticles (SPIONs) are used in many biological applications, which necessitate intracellular targeting. Here, we investigate intracellular localization and gene expression in HeLa cells after treatment with functionalized S ...

RNA-Protein interactions at AU-rich elements

Ramona Pauchard-Batschulat

The expression of many proto-oncogenes, nuclear transcription factors and cytokines is regulated post-transcriptionally by specific interactions between distinct cis-elements within the mRNA and trans-acting factors that bind to these elements and thereby ...

Development and application of experimental tools to elucidate the gene regulatory network underlying adipogenesis

Carine Delattre-Gubelmann

Excess fat mass in obese individuals, which is characterized by an increase of white adipocyte cell size and number, significantly raises the risk of developing metabolic syndrome symptoms as well as cancer. A detailed understanding of the transcriptional ...

Highly Specific Methods for the Prediction of Genes Regulated by MicroRNAs

Ray Marcel Marin Florez

MicroRNAs (miRNAs) comprise a large set of short noncoding RNAs that bind to messenger RNAs (mRNAs) to reduce their translation into functional proteins. Computational prediction of miRNA targets is the first stage in the discovery and validation of new re ...

Gene expression analysis on a single cell level in Purkinje cells of Huntington's disease transgenic mice

Ataxia is a clinical feature of most polyglutamine disorders. Cerebellar neurodegeneration of Purkinje cells (PCs) in Huntington's Disease (HD) brain was described in the 1980s. PC death in the R6/2 transgenic model for HD was published by Turmaine et al. ...

Comparative analyses of Purkinje cell gene expression profiles reveal shared molecular abnormalities in models of different polyglutamine diseases

Polyglutamine (PolyQ) diseases have common features that include progressive selective neurodegeneration and the formation of protein aggregates. There is growing evidence to suggest that critical nuclear events lead to transcriptional alterations in PolyQ ...
