Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Investigating transcription factor dynamics in health and disease using FRAP

open access: yesFEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

RNA compaction and iterative scanning for small RNA targets by the Hfq chaperone

open access: yesNature Communications
RNA-guided enzymes must quickly search a vast sequence space for their targets. This search is aided by chaperones such as Hfq, a protein that mediates regulation by bacterial small RNAs (sRNAs).

AscF in the mycobacterial CIII–CIV supercomplex lacks metal and nucleotide binding but links malate oxidation to respiration

open access: yesFEBS Letters, EarlyView.
The mycobacterial CIII‐CIV respiratory supercomplex is an obligate assembly, encompassing several subunits of unknown functions. We have characterized the intracellular subunit AscF, and show that it is unlikely to be a sensor for metals or nucleotides, but is required for growth on nonfermentable energy sources, and likely works as an adapter for ...

Mapping Current Studies of tRNA Fragments onto Disease Landscape

open access: yesBiomolecules
Transfer-RNA-derived fragments (tRFs) are a relatively recently discovered class of non-coding RNAs derived from both precursor and mature transfer RNAs (tRNAs).

The complete plastid genome of a marine microalgae Cryptophyceae sp. CCMP2293 (Cryptophyta)

open access: yesMitochondrial DNA. Part B. Resources, 2019
In this study, we present the complete plastid genome of Cryptophyceae sp. CCMP2293. The circular genome is 139,208 bp in length and contains 142 protein-coding genes (PCGs), 30 transfer RNA (tRNA) genes, 6 ribosome RNA (rRNA) genes, and 1 transfer ...

The therapeutic opportunities and pitfalls of using iron ion chelators to treat neurodegenerative diseases

open access: yesFEBS Letters, EarlyView.
Although too much iron in the brain promotes neurodegeneration, iron ion chelators have had mixed effects in clinical trials. This review explains why; some chelators do not render the iron redox‐inactive (e.g., L1) whereas others do (e.g., desferrioxamine).

Identification of the plant mitochondrial OrfX protein: A mass spectrometry approach

open access: yesFEBS Letters, EarlyView.
The mitochondrial genome of plants contains an open reading frame, orfx, which encodes a rare protein that has so far escaped mass spectrometric detection. The protein resembles the c‐subunit of bacterial twin‐arginine‐motif‐dependent protein translocases (TatC).

Prebiotic chiral transfer from self-aminoacylating ribozymes may favor either handedness

open access: yesNature Communications
Modern life is essentially homochiral, containing D-sugars in nucleic acid backbones and L-amino acids in proteins. Since coded proteins are theorized to have developed from a prebiotic RNA World, the homochirality of L-amino acids observed in all known ...

THE STRUCTURES AND FUNCTIONS OF TRANSFER RNA

open access: yesProgress in Biophysics and Molecular Biology, 1978
Publisher Summary Transfer ribonucleic acid (tRNA) is the term used to describe a group of low molecular weight RNA molecules that play a vital part in protein synthesis Transfer RNAs were assigned the role of adaptor molecules by Hoagland et al.
