Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Five novel cis-regulatory deletions of SOX10 cause Waardenburg syndrome type II

Frontiers in Audiology and Otology
IntroductionWaardenburg syndrome (WS) is a genetic disorder characterized by hearing loss, hypopigmentation, and distinct facial features. Despite > 60% molecular diagnosis rate for WS patients, pathogenic variants within coding regions are ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Optimised plasmids for sustained transgene expression in vivo

, 2010
Plasmid based gene therapy approaches often lack long term transgene expression in vivo due to silencing or loss of the vector. One way to overcome these limitations is to combine non-silenced promoters with strong viral enhancers.

Promoter-proximal tethering elements regulate enhancer-promoter specificity in the Drosophila Antennapedia complex [PDF]

, 2002
Insulator DNAs and promoter competition regulate enhancer–promoter interactions within complex genetic loci. Here we provide evidence for a third mechanism: promoter-proximal tethering elements.

Rare Variant Burden Analysis within Enhancers Identifies CAV1 as an ALS Risk Gene

Cell Reports, 2020
Summary: Amyotrophic lateral sclerosis (ALS) is an incurable neurodegenerative disease. CAV1 and CAV2 organize membrane lipid rafts (MLRs) important for cell signaling and neuronal survival, and overexpression of CAV1 ameliorates ALS phenotypes in vivo ...

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

FEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

The 89,000-Mr murine cytomegalovirus immediate-early protein activates gene transcription [PDF]

, 1986
To study trans-activation of gene expression by murine cytomegalovirus (MCMV) immediate-early (IE) proteins, the IE coding region 1 (ie1), which encodes the 89,000-Mr IE phosphoprotein (pp89), was stably introduced into L cells.
