Effect of oxidative stress on ABC transporters: contribution to epilepsy pharmacoresistance [PDF]

open access: yes, 2017
Epilepsy is a neurological disorder affecting around 1%-2% of population worldwide and its treatment includes use of antiepileptic drugs to control seizures. Failure to respond to antiepileptic drug therapy is a major clinical problem and over expression

Contribution of Gli1+ Adventitial Stem Cells to Smooth Muscle Cells in Atherosclerosis and Vascular Injury

open access: yesAdvanced Science, EarlyView.
Gli1+ adventitial stem cells (ASCs) have been thought to generate smooth muscle cells (SMCs) in atherosclerosis. Using a dual‐recombinase lineage tracing to exclude ectopic labeling, Wang et al. found that Gli1+ ASCs do not contribute to SMCs in atherosclerotic plaques.

Structural basis for the mechanism of ABC transporters. [PDF]

open access: yes, 2015
The ATP-binding cassette (ABC) transporters are primary transporters that couple the energy stored in adenosine triphosphate (ATP) to the movement of molecules across the membrane.

Autopolyploidization‐Induced Chromatin Remodeling Regulates Leaf Size Variation in Brassica rapa

open access: yesAdvanced Science, EarlyView.
This study demonstrates that monoploid, diploid, and autotetraploid Brassica rapa lines derived from the same genome exhibit distinct leaf morphology. Ploidy changes remodel chromatin accessibility and histone modifications to regulate gene expression, while key transcription factors BrGRF13 and BrARF11 control leaf size and polarity, driving ...

Chlamydial infection from outside to inside [PDF]

open access: yes, 2019
Chlamydia are obligate intracellular bacteria, characterized by a unique biphasic developmental cycle. Specific interactions with the host cell are crucial for the bacteria's survival and amplification because of the reduced chlamydial genome.

Endocytic Control of Cell‐Autonomous and Non‐Cell‐Autonomous Functions of p53

open access: yesAdvanced Science, EarlyView.
NUMB Ex3‐containing isoforms localize to the plasma membrane, where they recruit p53 through SNX9 and direct it to multivesicular bodies and exosomes. Exported p53 is taken up by neighboring cells and activates nuclear programs, revealing an intercellular, exosome‐based pathway that might help establish a tumor‐suppressive microenvironment.

Convergent Loss of ABC Transporter Genes From Clostridioides difficile Genomes Is Associated With Impaired Tyrosine Uptake and p-Cresol Production

open access: yesFrontiers in Microbiology, 2018
We report the frequent, convergent loss of two genes encoding the substrate-binding protein and the ATP-binding protein of an ATP-binding cassette (ABC) transporter from the genomes of unrelated Clostridioides difficile strains.

NPM1 Mediates mRNA Sorting into Extracellular Vesicles via Specific RNA Motif Binding and Phase Separation

open access: yesAdvanced Science, EarlyView.
NPM1 selectively sorts specific mRNAs into extracellular vesicles (EVs) by recognizing RNA motifs and forming phase‐separated condensates. These mRNA cargos—including EGFR—are then loaded via multivesicular bodies. This active sorting pathway, validated in EVs derived from both lung cancer cells and patient serum, reveals a specific mechanism for ...

Gene identification for the cblD defect of vitamin B12 metabolism [PDF]

open access: yes, 2008
Background Vitamin B12 (cobalamin) is an essential cofactor in several metabolic pathways. Intracellular conversion of cobalamin to its two coenzymes, adenosylcobalamin in mitochondria and methylcobalamin in the cytoplasm, is necessary for the ...

Chloroplast Stress Signals Orchestrate Epidermis‐Specific Remodeling of Mitochondria and ER Under High Light

open access: yesAdvanced Science, EarlyView.
High light exposure triggers an epidermis‐specific remodeling of mitochondria and ER in Arabidopsis, driven by chloroplast‐derived signals. Live‐cell imaging shows that HL rapidly suppresses mitochondrial motility, followed by fusion‐driven elongation and ER cisternal expansion.
