Integrated Single‐Cell and Spatial Transcriptomics Reveal Convergence on a Senescence‐Associated B Cell–MIF Signaling Axis in Joint Aging and Osteoarthritis Progression

open access: yesAdvanced Science, EarlyView.
Single‐cell and spatial transcriptomics implicate senescent B cells and macrophage migration inhibitory factor (MIF) signaling in aging and osteoarthritic joints. An injectable hydrogel combining quercetin with siRNA targeting MIF attenuates cartilage degeneration in a mouse model of osteoarthritis.

Galactosialidosis in two siblings

open access: yesThe Turkish Journal of Pediatrics, 1996
Galactosialidosis is a rare lysosomal storage disease associated with deficiencies of alpha-galactosidase and beta-neurominidase. In this report, two siblings with galactosialidosis, resembling Niemann-Pick disease with the presence of foamy cells

A Bi‐Adjuvant Senolytic Nanovaccine Modulating Dendritic Cell Senescence Ameliorates Aging‐Related Metabolic Dysfunction

open access: yesAdvanced Science, EarlyView.
An active biomaterial‐based bi‐adjuvant nanovaccine restores the immunocompetence of aged dendritic cells to overcome senescent cell tolerance. Accompanied by the downregulation of mitotic kinases Aurka/b and attenuation of senescence‐associated PI3K/AKT phosphorylation, the nanovaccine enhances antigen‐presenting capacity and promotes potent cytotoxic

Separation of beta-D-galactosidases in rabbit tissues: genetics of neutral beta-D-galactosidase.

open access: yes, 1983
Three different types of beta-D-galactosidase (EC 3.2.1.23) could be distinguished in rabbit tissues using electrophoretic procedures. (1) Acid beta-D-galactosidase with a low mobility and maximal activity at pH 3-5 was found in the particulate ...

A UBE3A‐UTX Proteostasis‐Epigenetic Axis Governs Hypothalamic Energy Homeostasis

open access: yesAdvanced Science, EarlyView.
Ubiquitin protein ligase E3A (UBE3A) regulates hypothalamic energy homeostasis and promotes degradation of the histone demethylase UTX (KDM6A). Neuronal UBE3A loss increases susceptibility to diet‐induced obesity and is accompanied by UTX accumulation, reduced histone H3 lysine 27 trimethylation, and altered endoplasmic reticulum stress‐responsive gene

A study on enzyme activities of some sphingolipidoses

open access: yesThe Turkish Journal of Pediatrics, 1994
Enzyme activities were determined in fibroblast cell cultures of eight patients suspected of having a type of sphingolipidosis. The patients were 0 to 4 years of age; four were female and four were male.

PHGDH‐Mediated Serine Metabolism in Nucleus Pulposus Cells Is a Potential Therapeutic Target for Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
When nucleus pulposus cells senesce, PHGDH decreases, reducing serine synthesis and glutathione, impairing antioxidant capacity. The intermediate α‐KG also drops, lowering JMJD3 demethylase activity, increasing H3K27me3 at the Rap1b promoter, and reducing Rap1b expression, whose down‐regulation in turn activates mTORC1 and suppresses autophagy ...
