Frontiers in LONP1 research: Unraveling molecular mechanisms, disease associations, and therapeutic strategies

Mitochondrial Communications
LONP1 is a conserved mitochondrial AAA + protease central to mitochondrial proteostasis. This review summarizes its structural features, protease-chaperone functions, and roles in metabolic regulation (heme/sulfur/steroid pathways) and disease. In cancer,

Aberrant Autophagic Response in The Muscle of A Knock-in Mouse Model of Spinal and Bulbar Muscular Atrophy [PDF]

, 2015
Spinal and bulbar muscular atrophy (SBMA) is characterized by loss of motoneurons and sensory neurons, accompanied by atrophy of muscle cells. SBMA is due to an androgen receptor containing a polyglutamine tract (ARpolyQ) that misfolds and aggregates ...

Cryo‐EM Structures Reveal the Molecular Basis of Asymmetric Allosteric Activation by MMOB in the Hydroxylase of Soluble Methane Monooxygenase

Advanced Science, EarlyView.
Cryo‐EM analysis reveals an asymmetric MMOH–MMOB complex with distinct protomers, where MMOB binding triggers structural rearrangements from the surface to the active site. This conformational asymmetry shortens the Fe···Fe distance to 2.7 Å in one protomer, forming a geometry suitable for O2 activation and supporting a sequential catalytic mechanism ...

Non‐Targeting shRNA‐Encoded Plasmid DNA Enhances Protective Immunity Through RIDD‐RIG‐I Signaling Pathway in the Zika Virus Animal Model

Advanced Science, EarlyView.
We present a novel DNA vaccine platform featuring intrinsic, non‐targeting dsRNA that significantly enhances immune responses by activating the regulated IRE1‐dependent decay‐RIG‐I signaling pathway. This research elucidates a previously uncharacterized mechanism for dsRNA‐mediated innate immune activation.

Heat shock protein 90 inhibition: rationale and clinical potential

Therapeutic Advances in Medical Oncology, 2012
Heat shock protein 90 (HSP90) is a molecular chaperone protein essential for cellular survival. Functionally, HSPs promote proper protein folding, prevent misfolding, and restore three-dimensional protein structure which is critical following toxic ...

Structure, Function, and Clinical Relevance of Molecular Chaperones – A Review Article

International Journal of Medical Science and Dental Health
Proteins known as molecular chaperones are essential components of cellular protein homeostasis since these proteins assist others in folding and stabilizing or degrading the polypeptides. The principle is that if misfolded or aggregated proteins—common in many pathologies such as cancer, neurodegenerative, and genetic diseases—are inhibited from ...

Thermally Gated Dual‐Cascade Nanozyme for Enhanced Mild‐Temperature Photothermal Therapy

Advanced Science, EarlyView.
A thermo‐responsive cascade nanozyme (Ru‐GOx‐PNN) synergistically enhances mild photothermal therapy by dual suppression of HSP70 through ROS‐induced lipid peroxidation and ATP depletion. This intelligent system effectively overcomes thermotolerance and amplifies apoptosis, offering a safe and precise strategy for tumor treatment.

Rapid and long‐lasting efficacy of high‐dose ambroxol therapy for neuronopathic Gaucher disease: A case report and literature review

Molecular Genetics & Genomic Medicine
Gaucher disease (GD) is a lysosomal storage disorder caused by a deficiency in the GBA1‐encoded enzyme, β‐glucocerebrosidase. Enzyme replacement therapy is ineffective for neuronopathic Gaucher disease (nGD).
