Transient vitamin B5 starving improves mammalian cell homeostasis and protein production

Maintaining a metabolic steady state is essential for an organism's fitness and survival when confronted with environmental stress, and metabolic imbalance can be reversed by exposing the organism to fasting. Here, we attempted to apply this physiological ...

In Vivo Pre-Instructed HSCs Robustly Execute Asymmetric Cell Divisions In Vitro

Matthias Lütolf, Aline Roch, Vincent Trachsel, Mukul Girotra

Hematopoietic stem cells (HSCs) are responsible for life-long production of all mature blood cells. Under homeostasis, HSCs in their native bone marrow niches are believed to undergo asymmetric cell divisions (ACDs), with one daughter cell maintaining HSC ...

Development of chemical biology tools to reveal the function and organization of the silenced chromatin state

Nora Guidotti

Effector proteins are recruited to chromatin via transient interactions between their reader domains and histone post-translational modification (PTM) patterns. These interactions form signaling pathways that control gene expression or repression and which ...

Single-Cell Tracing Dissects Regulation of Maintenance and Inheritance of Transcriptional Reinduction Memory

Sebastian Maerkl, Johannes Becker

Transcriptional memory of gene expression enables adaptation to repeated stimuli across many organisms. However, the regulation and heritability of transcriptional memory in single cells and through divisions remains poorly understood. Here, we combined mi ...

Roles of Epigenetic Dysregulation in Cancer Progression and Metastasis

Mohammad Sadegh Saghafinia

Nearly all the cells of an organism share the same DNA sequence or genome, and yet they show different phenotypes and carry out different functions. This diversity is made possible by a verity of molecular modifications acting on the DNA sequence that coll ...

Memory and relatedness of transcriptional activity in mammalian cell lineages

Felix Naef, David Michael Suter, Aleksandra Mandic, Saeed Omidi Klishami, Nicholas Edward Phillips

Phenotypically identical mammalian cells often display considerable variability in transcript levels of individual genes. How transcriptional activity propagates in cell lineages, and how this varies across genes is poorly understood. Here we combine live- ...

The role of OCT4 and SOX2 in regulating chromatin accessibility and cell fate across the cell cycle in embryonic stem cells

Torgil Elias Friman

Precise spatiotemporal regulation of gene expression is essential for development and homeostasis of complex organisms. This is achieved in large part by sequence-specific transcription factors (TF) that bind to genomic regulatory elements to activate or r ...

Exploring on Protein-DNA interactions

Alexandra Styliani Kalantzi

A variety of DNA-binding proteins organizes the chromosomal DNA and regulates gene transcription, and DNA replication and recombination. In particular, for gene regulation there is a category of DNA-binding proteins, the transcription factors, which can de ...

Recombinant Proteins for Industrial versus Pharmaceutical Purposes: A Review of Process and Pricing

Florian Maria Wurm

Recombinant proteins have been produced for over 30 years. Applications range from enzymes used in laundry detergents to antigen-detecting antibodies in cancer therapy. Despite similarities in manufacturing, drastic differences in retail pricing between re ...

A Derived Positional Mapping of Inhibitory Subtypes in the Somatosensory Cortex

Henry Markram, Olivier Burri, Felix Schürmann, Julie Meystre, Daniel Keller, Romain Guiet, Rahul Valiya Veettil

Obtaining a catalog of cell types is a fundamental building block for understanding the brain. The ideal classification of cell-types is based on the profile of molecules expressed by a cell, in particular, the profile of genes expressed. One strategy is, ...

Studying the roundworm Caenorhabditis elegans using microfluidic chips

Martinus Gijs

C. elegans is an attractive model organism in biology, as it shows genetic similarity with humans, facilitates microscopic observation due to its transparency, and has a short life cycle. Moreover, many mutants expressing fluorescent proteins in particular ...
