Restoration of SIRT3 Expression in Aged Mice Alleviates UUO‐Induced Renal Fibrosis by Reducing GSK‐3β Hyperacetylation

Advanced Science, EarlyView.
SIRT3 expression is significantly downregulated in the aged kidney, rendering the kidney more vulnerable to fibrotic changes in obstructive nephropathy. By promoting GSK‐3β deacetylation, SIRT3 indirectly inhibits Wnt/β‐catenin signaling, thereby suppressing renal fibrosis.

Inhibition of UBE2C Promotes Parkin‐Mediated K63‐Linked Ubiquitination of TOP2A to Induce Senescence and Increase Sensitivity of Doxorubicin in Breast Cancer

Advanced Science, EarlyView.
In the study, UBE2C was found to be significantly overexpressed in breast cancer and transcriptionally regulated by FOXM1. Inhibition of UBE2C suppressed proliferation, induced senescence, and sensitized breast cancer cells to doxorubicin. Mechanistically, UBE2C inhibition promoted Parkin‐mediated K63‐linked ubiquitination of TOP2A.

Lactate‐Activated GPR132‐Src Signal Induces Macrophage Senescence and Aggravates Atherosclerosis Under Diabetes

Advanced Science, EarlyView.
Elevated lactate in diabetes activates the GPR132‐Src pathway in macrophages, inducing macrophage senescence and further enhancing foam cell formation. This mechanism exacerbates atherosclerotic progression. Abstract Diabetes is widely acknowledged as a significant risk factor for atherosclerosis, facilitating plaque formation through various ...

Osteoblast‐CD4+ CTL Crosstalk Mediated by SIRT1/DAAM2 Axis Prevents Age‐Related Bone Loss

Advanced Science, EarlyView.
In the osteoblastic niche, SIRT1 activates and recruits CD4+ CTLs by increasing DAAM2 expression via EZH2 deacetylation and boosting the secretion of key chemokines, such as CCL3, CCL5, and CXCL10. Then, CD4+ CTL directly eliminates senescent osteoblasts in an MHC‐II‐dependent way, thereby slowing down the process of bone ageing and effectively ...

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

Peptide‐Based Biomaterials as a Promising Tool for Cancer Radiotherapy

Advanced Science, EarlyView.
This review provides a systematic overview of peptide‐based biomaterials in tumor radiotherapy, covering their roles as both radiosensitizers and radiopharmaceuticals. Peptide‐based radiosensitizers are generally divided into three categories: peptides as direct radiosensitizers, peptides as carriers of radiosensitizers, and targeted‐peptide‐modified ...

Reference values for lysosomal enzymes activities using dried blood spots samples - a Brazilian experience

Diagnostic Pathology, 2010
Background Lysosomal storage diseases (LSD) are inherited disorders caused by deficiency of lysosomal enzymes in which early diagnosis is essential to provide timely treatment. This study reports interval values for the activity of lysosomal enzymes that

Molecular defect in combined beta-galactosidase and neuraminidase deficiency in man.

Proceedings of the National Academy of Sciences of the United States of America, 1982
In normal human fibroblasts, an enzymically active 85,000-dalton precursor form of beta-galactosidase is processed, via a number of intermediates, into a mature 64,000-dalton form.
