Protein clearance mechanisms and their demise in age-related neurodegenerative diseases

open access: yesAIMS Molecular Science, 2015
The accumulation of damaged proteins contributes to the etiology of neurodegenerative diseases such as Alzheimer’s, Parkinson’s, Huntington’s or amyotrophic lateral sclerosis. Protein aggregation and deposition are common features of these disorders that

IKK phosphorylates Huntingtin and targets it for degradation by the proteasome and lysosome [PDF]

open access: yes, 2009
Expansion of the polyglutamine repeat within the protein Huntingtin (Htt) causes Huntington's disease, a neurodegenerative disease associated with aging and the accumulation of mutant Htt in diseased neurons.

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations

open access: yesAdvanced Biology, Volume 9, Issue 3, March 2025.
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Amino acid sequences within the β1 domain of human apolipoprotein B can mediate rapid intracellular degradation

open access: yesJournal of Lipid Research, 2004
Apolipoprotein B (apoB)-48 contains a region termed the β1 domain that is predicted to be composed of extensive amphipathic β-strands. Analysis of truncated apoB variants revealed that sequences between the carboxyl termini of apoB-37 and apoB-42 ...

Cryo‐EM of Rationally Designed Photosystem I Nanoassembly on Graphene Validates Orientation‐Driven Enhancement of Photocatalytic Performance

open access: yesAdvanced Functional Materials, EarlyView.
The first cryo‐EM visualization and quantification of oriented Photosystem I (PSI) on single‐layer graphene is reported. Domain‐specific covalent anchoring of PSI, with the reducing side of the biophotocatalyst toward graphene, promotes three‐fold higher anodic photocurrent generation compared to a randomly physisorbed counterpart. This approach allows

Towards quantitative prediction of proteasomal digestion patterns of proteins

open access: yes, 2008
We discuss the problem of proteasomal degradation of proteins. Though proteasomes are important for all aspects of the cellular metabolism, some details of the physical mechanism of the process remain unknown.

Cytosolic chaperones influence the fate of a toxin dislocated from the endoplasmic reticulum [PDF]

open access: yes, 2008
The plant cytotoxin ricin enters target mammalian cells by receptor-mediated endocytosis and undergoes retrograde transport to the endoplasmic reticulum (ER).

Interfacial Bioengineering of Dynamic Networks Hybrid Hydrogel for Programmed Intervention in Oral Precancerous Epithelial States

open access: yesAdvanced Healthcare Materials, EarlyView.
This study develops a dual‐bioinspired hydrogel, MSA@PGel (macrophage membrane‐coated and salvianolic acid B/5‐aminolevulinic acid co‐loaded liposomes embedded in a polydopamine‐based gel), that integrates macrophage membrane‐mediated active targeting and mussel‐inspired wet adhesion for programmed intervention in oral precancerous lesions.

Mol. Cell. Proteomics [PDF]

open access: yes, 2012
Chemical cross-linking in combination with mass spectrometric analysis offers the potential to obtain low-resolution structural information from proteins and protein complexes. Identification of peptides connected by a cross-link provides direct evidence
