Epigallocatechin‐3‐Gallate Suppresses Glioma by Targeting Integrin αvβ3/FAK/ERK Signaling Axis and Matrix Metalloproteinases

Phytotherapy Research, EarlyView.
EGCG suppresses glioma progression by targeting integrin αvβ3/FAK/ERK signaling and inhibiting MMP‐2/MMP‐9‐mediated ECM degradation, thereby blocking proliferation, migration, invasion, and promoting apoptosis. ABSTRACT Epigallocatechin‐3‐gallate (EGCG), the most abundant and biologically active catechin in green tea, has been widely reported to ...

Betulin Protects Against Cardiac Hypertrophy by Improving AMPK/Nrf2‐Dependent Mitochondrial Function

Phytotherapy Research, EarlyView.
Betulin effectively mitigates pressure overload‐induced cardiac hypertrophy in both Ang II‐infused and TAC‐operated mice. Mechanistically, betulin activated AMPK phosphorylation, promoted Nrf2 nuclear translocation, and upregulated antioxidant genes (HO‐1 and NQO‐1), thereby restoring mitochondrial function in cardiomyocytes.

A Combined Colon Organoid‐Sensory Neuron Model Reveals Epithelial Contribution to Moringin Efficacy Against Painful Inflammatory Bowel Disease

Phytotherapy Research, EarlyView.
Experimental workflow and main findings of the study. ABSTRACT Visceral pain is a major symptom of inflammatory bowel diseases (IBDs), requiring effective treatment strategies. Gut epithelium, beyond maintaining barrier integrity and microbiota homeostasis, modulates neurosensorial circuitries, influencing visceral sensitivity.

Adenosine kinase from Cryptosporidium parvum

Molecular and Biochemical Parasitology, 2006
Analysis of the Cryptosporidium parvum genome demonstrates that the parasite cannot synthesize purines de novo and reveals that the sole route for purine salvage by the parasite is via adenosine kinase (CpAK). In order to initiate a biochemical characterization of CpAK and ultimately validate this apparently essential enzyme as a therapeutic target ...

Adenosine kinase from human liver

Biochimica et Biophysica Acta (BBA) - Enzymology, 1981
Adenosine kinase (ATP: adenosine 5'-phosphotransferase, EC 2.7.1.20) has been purified to homogeneity from human liver. The yield was 55% of the initial activity with a final specific activity of 6.3 mumol/min per mg protein. The molecular weight was estimated as about 40 000 by Sephadex G-100 gel filtration and polyacrylamide gel electrophoresis in ...

Nonnucleoside Inhibitors of Adenosine Kinase

Current Pharmaceutical Design, 2004
Adenosine (ADO) is an endogenous inhibitory neuromodulator that increases nociceptive thresholds in response to tissue trauma and inflammation. Adenosine kinase (AK) is a key intracellular enzyme regulating intra- and extracellular concentrations of ADO.

Regulation of adenosine kinase by adenosine analogs.

Molecular Pharmacology, 1988
The regulation of adenosine phosphorylation by adenosine analogs was studied using highly purified human placental adenosine kinase [ATP: adenosine 5'-phosphotransferase (EC 2.7.1.20)]. Our observations lead us to classify the analogs into three groups as follows: type I, 5'-N-ethylcarboxamidoadenosine and 5'-methylthioadenosine; type II, N6 ...

Adenosine Kinase Inhibitors

Current Pharmaceutical Design, 1998
Abstract: Adenosine (ADO) is an endogenous modulator of intercellular signaling that provides homeostatic reductions in cell excitability during tissue stress and trauma. The inhibitory actions of ADO are mediated by interactions with specific cell-surface G­ protein coupled receptors regulating membrane cation flux, polarization, and the release of ...
