Cytoskeleton–Membrane Uncoupling in Duchenne Muscular Dystrophy: Implications for Newborn Screening and Early Protection

Cytoskeleton, EarlyView.
ABSTRACT The cytoskeleton of striated muscle integrates force transmission, mechanotransduction, and sarcolemmal stability through coordinated networks of sarcomeres, costameres, and intermediate filaments. Together, these systems establish mechanical continuity between the contractile apparatus, the sarcolemma, and the extracellular matrix.

Challenges and Pitfalls to Diagnosing NUTM1‐Rearranged Neoplasia of the Pancreas by Cytology and Ancillary Studies

Diagnostic Cytopathology, EarlyView.
ABSTRACT Fine‐needle aspiration cytology specimens are frequently utilized for ancillary studies to identify diagnostic and prognostic information. This case highlights diagnostic pitfalls and challenges in diagnosing NUTM1‐rearranged neoplasia on pancreatic cytology.

Desmin: molecular interactions and putative functions of the muscle intermediate filament protein

Brazilian Journal of Medical and Biological Research, 2004
Desmin is the intermediate filament (IF) protein occurring exclusively in muscle and endothelial cells. There are other IF proteins in muscle such as nestin, peripherin, and vimentin, besides the ubiquitous lamins, but they are not unique to muscle ...

Primary Pulmonary Mesenchymal Neoplasm With EWSR1::CREM Fusion: Cytologic Findings and Molecular Diagnosis

Diagnostic Cytopathology, EarlyView.
ABSTRACT Background Primary pulmonary mesenchymal neoplasms with EWSR1::CREM fusion are rare. These lesions are challenging to diagnose by morphology and immunohistochemistry alone. Case A 66‐year‐old woman (ex‐smoker) was found to have a 1.3‐cm right lower lobe lung nodule that had grown very slowly over a 9‐year period.

Sodium hydrogen sulfide (NaHS) ameliorates alterations caused by cisplatin in filtration slit diaphragm and podocyte cytoskeletal in rat kidney [PDF]

Journal of Nephropathology, 2017
Background: Hydrogen sulfide (H2S) has been shown to have a protective role in various kidney disorders. Objectives: This study investigated the molecular mechanism of NaHS (a H2S donor) in treating on the renal damage induced by cisplatin (CP).Materials

Fhod3 in zebrafish supports myofibril stability during growth of embryonic skeletal muscle

Developmental Dynamics, EarlyView.
Abstract Background Actin filament organization in cardiomyocytes critically depends on the formin Fhod3, but a role for Fhod3 in skeletal muscle development has not yet been described. Results We demonstrate here that in zebrafish mutated for one of two fhod3 paralog genes, fhod3a, skeletal muscle of the trunk appears normal through 2 days post ...

Desmin and Plectin Recruitment to the Nucleus and Nuclei Orientation Are Lost in Emery-Dreifuss Muscular Dystrophy Myoblasts Subjected to Mechanical Stimulation

Cells
In muscle cells subjected to mechanical stimulation, LINC complex and cytoskeletal proteins are basic to preserve cellular architecture and maintain nuclei orientation and positioning. In this context, the role of lamin A/C remains mostly elusive.

Cardiomyopathies associated with the DES gene mutations: molecular pathogenesis and gene therapy approaches

Alʹmanah Kliničeskoj Mediciny, 2019
Cardiomyopathy (CMP) is a common group of cardiovascular disorders. Genetic (primary) cardiomyopathies are related to abnormalities in more than 100 genes, including the DES gene encoding desmin protein.

The Endothelial CXCR Family in Vascular Health and Disease

iNew Medicine, EarlyView.
ABSTRACT Endothelial cells (ECs) form the dynamic interface between blood and tissue, serving as key regulators of vascular homeostasis, inflammation, and repair. Among the molecular systems governing endothelial behavior, the C‐X‐C motif chemokine receptor (CXCR) family—originally characterized in immunology for its roles in leukocyte trafficking and ...
