Tau Aggregate Imaging and Transcriptomics of Alzheimer's Disease Brain at Different Stages of Disease

Advanced Science, EarlyView.
The protein aggregates and gene expression in the middle temporal gyrus (MTG) and somatosensory cortex (SOM) of the postmortem brains of 13 Alzheimer's disease patients were studied in detail, revealing that small hyperphosphorylated tau aggregates increase with Braak stage driven by microglial inflammation.

Modification of β-galactosidase for use in organic mono-phase hexanol system

Macedonian Journal of Chemistry and Chemical Engineering, 2009
Different methods for preparation of the Aspergillus oryzae β-galactosidase were evaluated and the total enzyme activity was determined in hexanol mono-phase system using p-nitrophenyl-β-D-galactoside as a substrate.

TGFBI Maintains Fibrocartilage Homeostasis by Restraining O‐GlcNAcylation to Inactivate and Destabilize ADAMTS16 in Temporomandibular Joint Osteoarthritis

Advanced Science, EarlyView.
TGFBI deficiency elevates O‐GlcNAcylation, promoting the transcriptional activation of ADAMTS16 and OGT‐mediated post‐translational modification of ADAMTS16 at Ser1170. This leads to its stabilization and accumulation, driving chondrocyte metabolic disorders and senescent phenotypes, ultimately resulting in fibrocartilage dysfunction and TMJOA ...

Ratiometric electrochemical detection of β-galactosidase [PDF]

, 2017
A novel ferrocene-based substrate for the ratiometric electrochemical detection of β-galactosidase was designed and synthesised. It was demonstrated to be an excellent electrochemical substrate for β-Gal detection with sensitivity as low as 0.1 U mL ...

Layer‐Specific Dermal and Subcutaneous Delivery via Modular LNP–Hydrogel‐Integrated Threaded Microneedles

Advanced Science, EarlyView.
Guided by spatial transcriptomics and clinical validation, a threaded microneedle platform enables precise layer‐specific delivery across the dermis and subcutaneous tissue. By addressing distinct pathogenic remodeling in different skin layers, this strategy coordinates compartment‐specific intervention, restores tissue architecture, and offers a ...

Rational design of a lipophilic β-galactosidase-responsive near-infrared probe for in vivo imaging of cellular senescence. [PDF]

Smart Mol
We developed a lipophilic near‑infrared probe (DCIP‑AcGal) that is specifically activated by senescence‑associated β‑galactosidase. After intravenous injection, it lights up therapy‑induced tumor senescence in living mice. Its optimized lipophilicity also enables blood‑brain barrier crossing to detect natural brain senescence ex vivo. This probe offers

Low copy number vectors for expression of fused genes to β-galactosidase inEscherichia coli [PDF]

FEMS Microbiology Letters, 1991
A series of six expression vectors, pXM184Lac.A, B, C, pXM184Z.A, B, C, based on the low copy plasmid pACYC184 that allow for expression of proteins fused to beta-galactosidase in Escherichia coli is described. A level of 50,000 units of beta-galactosidase is routinely observed and is easily identifiable on protein gels.
