Advanced Science, EarlyView.. ABSTRACT Neuroinflammation driven by microglial activation is a defining feature of Alzheimer's disease (AD), yet the molecular mechanisms sustaining this proinflammatory state remain unclear. Here, we identify the deubiquitinase OTUD7B as a critical regulator of microglial activation and AD pathology.

Assembly of the Drosophila 26 S proteasome is accompanied by extensive subunit rearrangements [PDF]
, 2002 The subunit contacts in the regulatory complex of the Drosophila 26 S proteasome were studied through the cross-linking of closely spaced subunits of the complex, and analysis of the cross-linking pattern in an immunoblot assay with the use of subunit ...

MAFb protein confers intrinsic resistance to proteasome inhibitors in multiple myeloma
BMC Cancer, 2018 Background Multiple myeloma (MM) patients with t(14;20) have a poor prognosis and their outcome has not improved following the introduction of bortezomib (Bzb).

Advanced Science, EarlyView.Dysregulated protein modifications drive tumorigenesis. RINES, an E3 ubiquitin ligase, represses tumor cell proliferation and metastasis by facilitating RING domain‐dependent, ubiquitin–proteasome‐mediated degradation of STAT3 and MYC, which consequently restrains cancer stemness and oncogenic progression.

Early Retinal UCHL1 Dysregulation Coupled With Synaptic Loss Reflects Alzheimer's Disease Severity
Advanced Science, EarlyView.This study identifies synapse‐enriched deubiquitinase UCHL1 as an early Aβ‐responsive regulator of retinal synaptopathy in Alzheimer's disease. Retinal UCHL1 loss accompanies excitatory synapse degeneration, p75NTR activation, and neuroinflammation, and predicts Braak stage and cognitive decline. Aβ42 fibrils trigger synaptic and UCHL1 depletion before

TED1 Promotes the Assembly of SCFD3‐D14‐D53 to Reinforce Strigolactone Signaling in Rice
Advanced Science, EarlyView.This study identifies TED1 as a positive regulator of strigolactones (SL) signaling in rice. The ted1 mutants display dwarfism and increased tillering with significantly reduced SLs sensitivity. Through its longer C‐terminal region, TED1 interacts with D53 and D14 to promote the assembly of SCFD3‐D14‐D53, thereby facilitating the efficient ...

Proteasome Inhibitors Stimulate Activator Protein-1 Pathway Via Reactive Oxygen Species Production
, 2009 In this report we explored the effects of proteasome inhibitors (MG132, aLLN, lactacystin and MG262) on interleukin-8 (IL-8) induction. In HEK293 cells, proteasome inhibitors could concentration-dependently increase IL-8 promoter and activator protein-1 (

Drought Stress Mediated Changes in Food Crops: Mechanisms and Remediation Strategies
Advanced Science, EarlyView.This work presents a multi‐scale framework for flavonoid‐mediated drought tolerance in staple food crops, integrating ROS redox regulation, antioxidant defense, rhizosphere microbial interactions, and sustainable agronomic practices. This interdisciplinary model provides core insights to develop climate‐resilient cropping systems and enhance global ...
