Comparison of Uncovered and Covered Biliary SEMS for the Salvage of Obstructed SEMS: A Multicenter Retrospective Propensity Score–Weighted Study

open access: yesJournal of Gastroenterology and Hepatology, EarlyView.
In patients undergoing secondary SEMS placement after initial uncovered stent failure, fully covered and uncovered SEMSs showed comparable patency, survival, and safety. However, mechanisms of recurrent biliary obstruction differed by stent type, with tumor ingrowth in uncovered SEMSs and sludge or food impaction in fully covered SEMSs.

microRNA‐mediated control of cell fate specification and patterning in Marchantia polymorpha

open access: yesNew Phytologist, EarlyView.
The gemma developmental program in Marchantia polymorpha is coordinated by MpMIR166‐mediated repression of MpC3HDZ and auxin homeostasis. Summary MicroRNAs (miRNAs) are small non‐coding RNA molecules essential for growth and development in eukaryotes. In plants, the master gene DICER‐LIKE 1 (DCL1) catalyzes the biogenesis of miRNAs by processing double‐

Synthesis of Chromen-4-One-Oxadiazole Substituted Analogs as Potent β-Glucuronidase Inhibitors

open access: yesMolecules, 2019
Chromen-4-one substituted oxadiazole analogs 1–19 have been synthesized, characterized and evaluated for β-glucuronidase inhibition. All analogs exhibited a variable degree of β-glucuronidase inhibitory activity with IC50 values ranging ...

A C‐repeat binding factor–salicylic acid (CBF–SA) module links wound‐induced evaporative cooling to tissue repair in plants

open access: yesNew Phytologist, EarlyView.
A model of the C‐repeat binding factor–salicylic acid (CBF–SA) module in plant wound healing. Summary Repairing damaged tissues is essential for the survival of all organisms. In plants, tissue injury rapidly triggers defense and repair programs. However, the molecular mechanisms linking early injury cues to the later stage of wound repair remain ...

Differential ubiquitin modifications of ESCRT‐I subunits VPS37‐1 and VPS28‐2 positively regulate plant immunity

open access: yesNew Phytologist, EarlyView.
The RING type ubiquitin ligase (E3), XBAT35.2, positively regulates FLS2‐mediated plant immunity against bacterial pathogens by modifying the ESCRT‐I subunits VPS28‐2 and VPS37‐1 with distinct ubiquitin chain types. Summary Sensing of pathogen‐associated molecular patterns (PAMPs) by pattern recognition receptors at the cell surface initiates the first

Comparative genomics of dark septate endophytes: shedding light on the enigmatic lifestyle and biology of DSEs

open access: yesNew Phytologist, EarlyView.
Ancestral lifestyle reconstruction across the phylogeny of the 107 analysed fungal genomes. Summary Dark septate endophytes (DSE) are widespread root‐colonising fungi with poorly understood lifestyle and ecological functions. We investigated their genomic traits, sexual reproduction signatures, carbohydrate‐active enzyme (CAZyme) and secondary ...

A regulatory locus for mouse beta-glucuronidase induction, Gur, controls messenger RNA activity.

open access: yes, 1979
A regulatory locus in a higher organism has been shown to control a specific messenger RNA activity. The Gur locus in mice regulates the production of kidney beta-glucuronidase messenger RNA activity after induction of the beta-glucuronidase ...

A single‐nucleus multiome profiling reveals the regulatory programs driving plant nematode–induced syncytium

open access: yesNew Phytologist, EarlyView.
Single‐nucleus transcriptome profiles of Heterodera schachtii–induced syncytium on Arabidopsis roots. Summary Plant‐parasitic cyst nematodes induce the formation of specialized feeding structures, known as syncytia, within host roots by orchestrating extensive transcriptional and epigenetic reprogramming.
