Meeting our Makers:Uncovering the cis-regulatory activity of transposable elements using statistical learning

The adaptation of organisms to their environment depends on the innovative potential inherent to genetic variation. In complex organisms such as mammals, processes like development and immunity require tight gene regulation. Complex forms emerge more often ...

Emergence of diauxie as an optimal growth strategy under resource allocation constraints in cellular metabolism

Vassily Hatzimanikatis, Pierre Guy Rémy Salvy

Diauxie, or the sequential consumption of carbohydrates in bacteria such as Escherichia coli, has been hypothesized to be an evolutionary strategy which allows the organism to maximize its instantaneous specific growth-giving the bacterium a competitive ad ...

KRAB zinc finger protein-mediated control of transposon-embedded regulatory sequences from human germline to early embryos

Alexandra Iouranova

Transposable elements (TEs), also called jumping genes, are genetic elements capable of changing their position within the genome of their host. They make up large fractions of genomes, including 45% of human DNA content, according to current estimates. S ...

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 ...

The RNA-Binding Protein PUM2 Impairs Mitochondrial Dynamics and Mitophagy During Aging

Johan Auwerx, Kristina Schoonjans, Bernard Schneider, Graham Knott, Davide D'Amico, Vera Monica Lemos Da Silva, Mario Romani, Hao Li, Vincenzo Sorrentino, Adrienne Joëlle Laurence Mottis, Francesca Potenza

Little information is available about how post-transcriptional mechanisms regulate the aging process. Here, we show that the RNA-binding protein Pumilio2 (PUM2), which is a translation repressor, is induced upon aging and acts as a negative regulator of li ...

Increased drug permeability of a stiffened mycobacterial outer membrane in cells lacking MFS transporter Rv1410 and lipoprotein LprG

Georg Fantner, Haig Alexander Eskandarian

The major facilitator superfamily transporter Rv1410 and the lipoprotein LprG (Rv1411) are encoded by a conserved two-gene operon and contribute to virulence in Mycobacterium tuberculosis. Rv1410 was originally postulated to function as a drug efflux pump, ...

Cell-free gene-regulatory network engineering with synthetic transcription factors

Sebastian Maerkl, Zoe Newell Swank, Nadanai Laohakunakorn

Gene-regulatory networks are ubiquitous in nature and critical for bottom-up engineering of synthetic networks. Transcriptional repression is a fundamental function that can be tuned at the level of DNA, protein, and cooperative protein-protein interaction ...

EZH2 oncogenic mutations drive epigenetic, transcriptional, and structural changes within chromatin domains

Suliana Manley, Elisa Oricchio, Kyle Michael Douglass, Daniele Tavernari, Natalya Katanayeva, Elena Battistello, Stephanie Jocelyne Sungalee, Maria Christine Donaldson, Timo Henry René Rey, Giovanni Ciriello, Marco Mina

Chromatin is organized into topologically associating domains (TADs) enriched in distinct histone marks. In cancer, gain-of-function mutations in the gene encoding the enhancer of zeste homolog 2 protein (EZH2) lead to a genome-wide increase in histone-3 L ...

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 ...

Functional analysis of the telomeric long non-coding RNA TERRA

Patricia Renck Nunes

Telomeres are nucleoprotein structures present in the end of linear chromosomes. In humans, a core complex of 6 proteins cap and protect the chromosome ends from being recognized as double-strand breaks and eliciting unwanted DNA damage and repair response ...
