Purification of alpha-galactosidase from seeds of Sesbania marginata

Brazilian Journal of Chemical Engineering, 2000
Alpha-galactosidase taken from a raw extract of Sesbania marginata legume seeds was purified by partitioning in aqueous two-phase systems (ATPS). Initially, galactomannan/dextran 2,000,000 systems were used for the purification, and the partition coefficients of a -galactosidase varied from 1.5 to 4.0.

Histone Lactylation Antagonizes Senescence and Skeletal Muscle Aging by Modulating Aging‐Related Pathways

Advanced Science, EarlyView.
This study reveals histone lactylation as a metabolic‐epigenetic regulator countering cellular senescence and skeletal muscle aging. Reduced lactylation impairs cell cycle, DNA repair and proteostasis pathways, while exercise restores glycolytic activity and lactylation levels, preserving muscle function.

Inhibition of Ferroptosis Delays Aging and Extends Healthspan Across Multiple Species

Advanced Science, EarlyView.
This study identifies ferroptosis as a key driver of cellular senescence, with its inhibition delaying aging and extending healthspan across species. During senescence, ferroptosis worsens, increasing oxidative stress and lipid peroxidation, which accelerate aging.

Ethylene‐Activated E3 Ubiquitin Ligase MdEAEL1 Promotes Apple Fruit Softening by Facilitating the Dissociation of Transcriptional Repressor Complexes

Advanced Science, EarlyView.
Ethylene‐activated MdEAEL1 mediates the disassembly of the MdZFP3‐MdTPL4‐MdHDA19 transcriptional repression complex, upregulating the histone acetylation levels in the promoter regions of cell wall degradation‐related genes, consequently promoting softening during storage.

Activator protein for the degradation of globotriaosylceramide by human alpha-galactosidase.

Journal of Biological Chemistry, 1983
An activator protein which stimulates the degradation of globotriaosylceramide by human hepatic alpha-galactosidase (alpha-D-galactoside galactohydrolase, EC 3.2.1.22) was isolated from human liver and purified some 1300-fold. The purified activator was heat stable up to 95 degrees C, its molecular weight was estimated at 20,000 by gel filtration ...

Mechanical Load‐Induced Upregulation of Talin2 through Non‐Canonical Deubiquitination of OTUB1 Drives Facet Joint Osteoarthritis Pathogenesis

Advanced Science, EarlyView.
Facet joint osteoarthritis (FJOA), prevalent in the elderly, involves Talin2 upregulation promoting ECM degradation while suppressing synthesis. Mechanical load stabilizes Talin2 via OTUB1‐mediated non‐canonical deubiquitination, driving CCL2 expression that recruits immune cells, exacerbating inflammatory joint degeneration.

Inhibition and Rescue of Hyperglycemia‐Induced Cellular Senescence by Mitochondrial Transfer from Enucleated Mesenchymal Stem Cell‐Derived Microvesicles for Chronic Wound Healing

Advanced Science, EarlyView.
This study develops enucleated MSC‐derived microvesicles (Mito@euMVs) to deliver functional mitochondria for optimizing wound repair. By efficiently encapsulating mitochondria, Mito@euMVs rejuvenate hyperglycemia‐induced senescent fibroblasts and HUVECs. Using PVA microneedle patches, the therapeutic efficacy of Mito@euMVs is validated in diabetic rats

Identification and Clinical Characterization of a Novel Alpha-Galactosidase A Mutation

Journal of Inborn Errors of Metabolism and Screening, 2014
Fabry disease (FD) is an inborn error of metabolism characterized by deficient/absent activity of lysosomal enzyme alpha-galactosidase A, which results in systemic accumulation of glycosphingolipids and progression to renal failure, heart and cerebrovascular disease, and small-fiber peripheral neuropathy.

Nephronectin (NPNT) is a Crucial Determinant of Idiopathic Pulmonary Fibrosis: Modulating Cellular Senescence via the ITGA3/YAP1 Signaling Axis

Advanced Science, EarlyView.
Through a comprehensive multi‐omics analysis, this study identifies a marked reduction in Nephronectin (NPNT) expression within fibrotic lung tissue. This reduction impairs the binding capability to the ITGA3 receptor, consequently causing YAP1 to persist in the cytoplasm, where it undergoes degradation.
