Vm–MSI: a Vancomycin–Antimicrobial Peptide Conjugate Combating Resistant Bacteria and Broadening the Antimicrobial Spectrum

open access: yesAdvanced Science, EarlyView.
A series of vancomycin‐antimicrobial peptide conjugates is synthesized and evaluated to identify the optimal combination. Vm‐MSI, selected from multiple candidates, exhibited potent activity against vancomycin‐resistant and Gram‐negative bacteria by disrupting membranes and inducing oxidative stress, thereby expanding vancomycin's antibacterial ...

EIF1AX Nucleolar Condensates Enhance Susceptibilities for the Management of Endometrial Cancer

open access: yesAdvanced Science, EarlyView.
This schematic illustrates the mechanism of a senolytic strategy in endometrial cancer. EIF1AX facilitates the incorporation of DDX21 into nucleolar condensates, an event that suppresses rDNA transcription and induces cellular senescence. The compound 2,5‐MeC exploits this pathway by promoting EIF1AX nucleolar translocation and condensate formation ...

Small Non-Coding RNAs Derived from Eukaryotic Ribosomal RNA

open access: yesNon-Coding RNA, 2019
The advent of RNA-sequencing (RNA-Seq) technologies has markedly improved our knowledge and expanded the compendium of small non-coding RNAs, most of which derive from the processing of longer RNA precursors.

Structural and Functional Characterization of EXPO‐Derived Extracellular Vesicles in Plants

open access: yesAdvanced Science, EarlyView.
In this study, 3D electron tomography (ET), cryo‐ET, and immunogold transmission electron microscopy (TEM) are employed to characterize plant extracellular vesicles (EVs) under physiological conditions. EVs are classified into three distinct categories according to their size, content, and molecular‐marker profiles. Furthermore, Exo70E2‐positive medium

Ribosome surface properties may impose limits on the nature of the cytoplasmic proteome

open access: yeseLife, 2017
Much of the molecular motion in the cytoplasm is diffusive, which possibly limits the tempo of processes. We studied the dependence of protein mobility on protein surface properties and ionic strength.

Vitamin D Regulates Olfactory Function via Dual Transcriptional and mTOR‐Dependent Translational Control of Synaptic Proteins

open access: yesAdvanced Science, EarlyView.
Vitamin D (VitD) modulates olfactory function by remodeling dendrodendritic synapses in tufted cells through vitamin D receptor‐dependent transcriptional and translational mechanisms. VitD regulates synaptic protein translation partially via mTOR signaling.

Ribosomes slide on lysine-encoding homopolymeric A stretches

open access: yeseLife, 2015
Protein output from synonymous codons is thought to be equivalent if appropriate tRNAs are sufficiently abundant. Here we show that mRNAs encoding iterated lysine codons, AAA or AAG, differentially impact protein synthesis: insertion of iterated AAA ...

A Unique Chimeric RNA: ERCC1‐iASPP Drives Benzo[a]pyrene‐Induced Lung Carcinogenesis via Dual Coding and Non‐Coding Mechanisms

open access: yesAdvanced Science, EarlyView.
The chimeric RNA ERCC1‐iASPP possesses dual coding and non‐coding functions, synergistically accelerating the process of cellular malignant transformation. Abstract Genetic variation at 19q13.3 critically modulates chemical carcinogen‐induced lung carcinogenesis, particularly in mediating the activity of benzo[a]pyrene (B[a]P), a major polycyclic ...

Quantitative profiling of initiating ribosomes in vivo

open access: yesNature Methods, 2014
Cells have evolved exquisite mechanisms to fine-tune the rate of protein synthesis in response to stress. Systemic mapping of start-codon positions and precise measurement of the corresponding initiation rate would transform our understanding of ...
