Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Synergistic effects between analogs of DNA and RNA improve the potency of siRNA-mediated gene silencing

, 2010
We report that combining a DNA analog (2?F-ANA) with rigid RNA analogs [2?F-RNA and/or locked nucleic acid (LNA)] in siRNA duplexes can produce gene silencing agents with enhanced potency. The favored conformations of these two analogs are different, and

Mutations in the U5 snRNA result in altered splicing of subsets of pre-mRNAs and reduced stability of Prp8 [PDF]

, 2009
The U5 snRNA loop 1 aligns the 5' and 3' exons for ligation during the second step of pre-mRNA splicing. U5 is intimately associated with Prp8, which mediates pre-mRNA repositioning within the catalytic core of the spliceosome and interacts directly with

Formamide significantly enhances the efficiency of chemical adenylation of RNA sequencing ligation adaptors [PDF]

, 2023
Preadenylated single-stranded DNA ligation adaptors are essential reagents in many next generation RNA sequencing library preparation protocols. These oligonucleotides can be adenylated enzymatically or chemically.

AMPK phosphosite profiling by label-free mass spectrometry reveals a multitude of mTORC1-regulated substrates

npj Metabolic Health and Disease
The nutrient-sensitive protein kinases AMPK and mTORC1 form a fundamental negative feedback loop that governs cell growth and proliferation. mTORC1 phosphorylates α2-S345 in the AMPK αβγ heterotrimer to suppress its activity and promote cell ...

Expanding access to HIV viral load testing: a systematic review of RNA stability in EDTA tubes and PPT beyond current time and temperature thresholds.

PLoS ONE, 2014
BackgroundHIV viral load (VL) testing is the gold standard for antiretroviral treatment monitoring, but many barriers exist to VL testing in resource-limited settings, including storage and transport limitations for whole blood and plasma.

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

FEBS 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

FEBS 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 ...

Structural insights into the dynamics and function of the C-terminus of the E. coli RNA chaperone Hfq [PDF]

, 2011
The hexameric Escherichia coli RNA chaperone Hfq (Hfq(Ec)) is involved in riboregulation of target mRNAs by small trans-encoded RNAs. Hfq proteins of different bacteria comprise an evolutionarily conserved core, whereas the C-terminus is variable in ...
