Targeting the post-translational proteome with intrabodies [PDF]

, 2019
The complexity of the proteome exceeds that of the genome. Post-translational modifications (PTMs) and conformational changes of proteins trigger new molecular interactions whose systematic elucidation is hampered by the lack of specific tools.

Structure, Mechanics, and Mechanobiology of Fibrocartilage Pericellular Matrix Mediated by Type V Collagen

Advanced Science, EarlyView.
This study defines the structure, mechanics, and mechanobiology of the fibrocartilage pericellular matrix (PCM) using the murine meniscus, showing how collagen V deficiency alters PCM properties and disrupts cell mechanosensitive signaling. Findings emphasize the critical role of PCM in fibrocartilage mechanobiology and suggest targeting it can enhance

A Brief Review of Machine Learning Techniques for Protein Phosphorylation Sites Prediction [PDF]

arXiv, 2021
Post-translational modifications (PTMs) have vital roles in extending the functional diversity of proteins and as a result, regulating diverse cellular processes in prokaryotic and eukaryotic organisms. Phosphorylation modification is a vital PTM that occurs in most proteins and plays significant roles in many biological processes.

PSMD14 Stabilizes SLC7A11 to Ameliorate Glucocorticoid‐Induced Osteoporosis by Suppressing Osteocyte Ferroptosis

Advanced Science, EarlyView.
Glucocorticoid‐induced osteoporosis (GIOP) triggers osteocyte ferroptosis via SLC7A11 degradation. PSMD14 stabilizes SLC7A11 by counteracting glucocorticoid‐driven ubiquitination, preserving cystine uptake and glutathione synthesis. AAV‐mediated PSMD14 delivery or its agonist Pantethine rescues osteocyte survival and bone loss in GIOP mice.

Nuclear processes associated with plant immunity and pathogen susceptibility [PDF]

, 2015
Plants are sessile organisms that have evolved exquisite and sophisticated mechanisms to adapt to their biotic and abiotic environment. Plants deploy receptors and vast signalling networks to detect, transmit and respond to a given biotic threat by ...

Listerin Alleviates Alzheimer's Disease through IRE1‐mediated Decay of TLR4 mRNA

Advanced Science, EarlyView.
Alzheimer's disease (AD) progression is influenced by microglia‐mediated neuroinflammation. Here, it is demonstrated that Listerin suppresses neuroinflammatory signaling and cognitive impairment in AD models by triggering IRE1α‐mediated TLR4 mRNA decay. Adenoviral Listerin delivery reduces amyloid‐β pathology, positioning it as a new therapeutic target.

Hypoxia and hypoxia mimetics differentially modulate histone post-translational modifications

Epigenetics, 2021
Post-translational modifications (PTMs) to the tails of the core histone proteins are critically involved in epigenetic regulation. Hypoxia affects histone modifications by altering the activities of histone-modifying enzymes and the levels of hypoxia ...
