Testicular SIRT1 Loss Reveals an Aging‐Like Proteomic Landscape and Precipitates Reproductive Deterioration

Andrology, EarlyView.
ABSTRACT Background Advanced paternal age is associated with reduced male fertility and testicular dysfunction. Among the molecular regulators involved in aging, SIRT1, a NAD+‐dependent deacetylase, plays a pivotal role in maintaining oxidative balance and cellular homeostasis.

14‐3‐3σ up‐regulation in the temporal cortex associates with tau pathology and reactive astroglia in Lewy body disorders

Brain Pathology, EarlyView.
14‐3‐3 protein homeostasis is disrupted in Lewy body pathology, showing a diminution of six isotypes and overexpression of stratifin. The latter was associated with stratifin colocalization with tau pathology and reactive astrocytes. Platelets, as a peripheral biomarker source, mirrored inversely cortical 14‐3‐3 gene expression patterns in dementia ...

Compartmentalisation in cAMP signalling: A phase separation perspective

British Journal of Pharmacology, EarlyView.
Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.

Opioids in breast cancer: Between analgesia and modulation of tumour progression

British Journal of Pharmacology, EarlyView.
Preclinical investigations consistently demonstrate that activation of μ‐opioid receptors and δ‐opioid receptors promote proliferation, migration, angiogenesis, epithelial‐mesenchymal transition, acquisition of cancer stem cell phenotypes, and chemoresistance.

Covalent drug discovery: Progress against key targets, emerging strategies and lessons learnt

British Journal of Pharmacology, EarlyView.
Abstract Covalent drug discovery is currently experiencing a boom in industrial and academic interest. To date, at least 75 covalent drugs have received regulatory approval, targeting both traditional target classes and more challenging proteins for which other approaches failed. In many cases, unique aspects of covalent targeting are essential for the

Opening closed inward rectifier potassium channel doors

British Journal of Pharmacology, EarlyView.
Inwardly rectifying potassium (KIR) channels are essential regulators of membrane potential in excitable and non‐excitable tissues. Although KIR channels exhibit a biophysical preference for potassium influx due to voltage‐dependent block of outward current by polyamines and Mg2+, under physiological conditions, they predominantly mediate K+ efflux ...

IRF4 Enhances Radiosensitivity of Cervical Cancer by Inhibiting the PI3K/Akt/mTOR Pathway to Regulate Autophagy

Cancer Science, EarlyView.
IRF4 is a prognostic biomarker in cervical cancer. IRF4 enhances radiosensitivity and inhibits tumor growth via PI3K/AKT/mTOR‐mediated autophagy. IRF4 boosts radiation response in vitro and in vivo. ABSTRACT Interferon regulatory factor 4 (IRF4), a critical member of the IRF transcription factor family, harbors an elusive biological role in cervical ...

Bioorganicheskaia khimiia, 2010
Chaperones are unique remodeling proteins that participate in a great number of intracellular processes and are involved in the correction of protein structure, the prevention of the aggregation of misfolded proteins, the destruction of protein aggregates, and also the unfolding of native protein targets for their translocation across a membrane.

Microbial molecular chaperones

2001
Protein folding in the cell, long thought to be a spontaneous process, in fact often requires the assistance of molecular chaperones. This is thought to be largely because of the danger of incorrect folding and aggregation of proteins, which is a particular problem in the crowded environment of the cell.
