PLXDC2 siRNA‐Mediated Intervention Attenuates Microglial Senescence Through cGAS‐STING Signaling

Advanced Science, EarlyView.
PLXDC2 was identified as a microglial target in Parkinson's disease through human and mouse single‐cell analyses. Ferritin‐armed biomimetic nanovesicles delivered PLXDC2 siRNA, deferoxamine, and CeO2 nanoparticles across the blood–brain barrier, reducing cGAS‐STING activation, iron burden, oxidative stress, and senescence in microglia, thereby ...

Multiple integration of the gene ganA into the Bacillus subtilis chromosome for enhanced β-galactosidase production using the CRISPR/Cas9 system

AMB Express, 2019
The ganA gene from Bacillus subtilis encoding a β-galactosidase for degradation of the galactomannan was integrated in different loci of the B. subtilis chromosome employing the CRISPR/Cas9 system. Hereby a total of five copies of ganA cassettes in which

Dual Repression by IPA1 Fine‐Tunes OsbZIP79‐Mediated Salt Tolerance in Rice

Advanced Science, EarlyView.
Dual repression by IPA1 fine‐tunes OsbZIP79‐mediated salt tolerance in rice: direct transcriptional inhibition under normal conditions and salt‐induced degradation under stress. This dual mechanism activates OsbZIP79 to regulate Na+/K+ homeostasis and redox balance via downstream genes, enabling optimal salt stress response.

A novel thermostable β-galactosidase from Bacillus coagulans with excellent hydrolysis ability for lactose in whey.

Journal of Dairy Science, 2019
β-galactosidase is one of the most important enzymes used in dairy industry. Here, a novel thermostable β-galactosidase was cloned and overexpressed from Bacillus coagulans NL01 in Escherichia coli.

Lactylation‐Driven PROS1‐TYRO3‐CARF Signaling Promotes Therapy‐Induced Senescence Escape and Radioresistance in Meningioma

Advanced Science, EarlyView.
A glycolysis‐driven epigenetic switch promotes therapy resistance in meningioma. Increased lactate production enhances histone H3K27 lactylation, which activates PROS1 secretion. Secreted PROS1 engages TYRO3 signaling to degrade the senescence regulator CARF, allowing cancer cells to escape growth arrest.

Purification and some properties of phospho-β-galactosidase from the Gram-negative oral bacterium Leptotrichia buccalis ATCC 14201 [PDF]

FEMS Microbiology Letters, 2002
Phospho-beta-galactosidase (P-beta-gal; EC 3.2.1.85) is induced during growth of Leptotrichia buccalis ATCC 14201 on lactose and lactulose. The enzyme has been purified to electrophoretic homogeneity (M(r) approximately 53 kDa, pI approximately 4.8), and kinetic parameters have been determined using the chromogenic analog o-nitrophenyl-beta-D ...

Temporal Trajectories of the Tau Aggregate Interactome Reveal Stage‐Specific Vulnerabilities in Alzheimer's Disease

Advanced Science, EarlyView.
Tau populations with different aggregation states associate with distinct sets of proteins in the Alzheimer's disease brain. Proteomic discovery combined with single‐molecule analysis in neurons reveals dynamic associations involving proteostasis, metabolism and RNA biology.

Hierarchical Nanoplatform Integrating Oxidative–Acidic Microenvironment Remodeling and Bone Homeostasis Modulation for Diabetic Bone Defect Therapy

Advanced Science, EarlyView.
A hierarchical CM/LDH nanoplatform integrates ROS‐scavenging Ce‐MOF nanozymes with acid‐neutralizing CaAl‐LDH and is delivered within GelMA hydrogel to diabetic bone defects. By remodeling the oxidative‐acidic microenvironment, preserving mitochondrial homeostasis, and suppressing mtDNA–cGAS–STING inflammatory signaling, CM/LDH reduces proinflammatory ...
