Regulation of Arabidopsis thaliana Calcineurin B-like Interacting Protein Kinases (CIPKs) by the Ubiquitin-Proteasome System

open access: yes, 2017
Ubiquitin Proteasome System (UPS) regulates the abundance of proteins by first attaching ubiquitin molecules and then targeting the modified protein for degradation by the 26S proteasome.

In Situ Profiling of Nanoscale Strains Uncovers Mechano‐Architectural Predictors of Aging and Osteoarthritis Emergence

open access: yesAdvanced Science, EarlyView.
In situ mechanical loading of osteoarthritis‐prone murine knee joints reveals that spatial alterations in subchondral plate microarchitecture precede cartilage loss and promote a shift from coordinated epiphyseal strain dissipation in healthy joints to focal subchondral strain concentration in osteoarthritis‐prone joints.

Pasta, a Versatile Transcriptomic Clock, Maps the Chemical and Genetic Determinants of Aging and Rejuvenation

open access: yesAdvanced Science, EarlyView.
Pasta is a transcriptomic aging clock built on an age‐shift learning framework and trained on 17 000 samples across 21 datasets. It accurately predicts relative biological age across tissues, platforms, and species, captures stemness‐to‐senescence transitions, and identifies age‐modulatory perturbations.

Deltacoronavirus Modulates circRNA cGLIS3 Metabolism to Evade Host Antiviral Response

open access: yesAdvanced Science, EarlyView.
This study reveals that both deltacoronavirus nucleocapsid protein and host RNA binding protein IGF2BP2 promote circular RNA GLIS3 (cGLIS3) biogenesis by binding to GLIS3 pre‐mRNA. The m6A modification‐mediated cGLIS3‐IGF2BP2 interaction weakens RNase L‐mediated degradation of cGLIS3 while facilitates a ubiquitin‐dependent degradation of IGF2BP2, thus ...

Miro1 Protects Against Acute Kidney Injury Through Modulating Mitochondrial Homeostasis via Interaction With Sirt6

open access: yesAdvanced Science, EarlyView.
Ischemia‐reperfusion reduces Sirt6 activity, thereby increasing Miro1 acetylation. Hyperacetylated Miro1 exhibits perinuclear distribution and degradation, thereby inducing mitochondrial dysfunction and promoting apoptosis in renal tubular epithelial cells. This pathway reveals a mechanistic link between Sirt6‐mediated deacetylation and Miro1 stability

A Single‐Amino‐Acid Ligand for LAT1: A Minimalist and Modular Platform for Lysosome‐Targeted Degradation of Membrane Proteins

open access: yesAdvanced Science, EarlyView.
LA‐LYTAC repurposes the cancer‐enriched amino acid transporter LAT1 as a lysosomal trafficking receptor for targeted membrane‐protein degradation. A single phenylalanine‐derived ligand, modularly linked to antibodies or small‐molecule binders, recruits PD‐L1, EGFR, or integrins to LAT1, triggering transporter‐mediated internalization, lysosomal ...

Innovative Test Strip‐Based Colorimetric Sensors Integrated With Affinity Chromatography: Acetylcholinesterase Inhibitor Screening Breakthrough in Lycium Barbarum Leaves

open access: yesAdvanced Science, EarlyView.
Schematic diagrams illustrating the breakthrough in the screening of AChE inhibitors from LBL, and the research process of the pharmacodynamics of the NCP are presented. ABSTRACT Current Alzheimer's drugs exhibit limited effectiveness, highlighting the necessity for multi‐target treatments.

Proteasome-mediated degradation of the C-terminus of the Alzheimer's disease β-amyloid protein precursor: effect of C-terminal truncation on the production of β-amyloid protein

open access: yes, 2003
The â-amyloid protein (Aâ) is derived by proteolytic processing of the amyloid protein precursor (APP). Cleavage of APP by â-secretase generates a C-terminal fragment (APP-CTFâ), which is subsequently cleaved by ã-secretase to produce Aâ.

Intratumoral Hypoxia Triggers Mitochondrial BHLHE40 ROS Sensing Pathway to Promote Radioresistance in Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
Hypoxia triggers a dual mechanism for BHLHE40 upregulation: reactive oxygen species (ROS)‐dependent post‐translational modification and hypoxia‐inducible factor (HIF)‐dependent transcriptional activation. Under hypoxic conditions, mitochondrial BHLHE40 accumulates and senses ROS via cysteine thiol oxidation and disulfide‐linked homodimer formation ...
