D‐glucuronyl C5‐Epimerase Binds to EGFR to Suppress Kidney Fibrosis

Advanced Science, EarlyView.
Glucuronyl C5‐epimerase (Hsepi, gene name Glce) is a key enzyme catalyzing heparan sulfate (HS) chain biosynthesis in HS proteoglycans, which are ubiquitously expressed on cell membranes. In normal renal tubular cells, Glce binds to the intracellular domains of EGFR, maintaining stable and orderly EGFR phosphorylation.

Prolyl 4-hydroxlase activity is essential for development and cuticle formation in the human infective parasitic nematode Brugia malayi [PDF]

, 2013
Collagen prolyl 4-hydroxylases (C-P4H) are required for formation of extracellular matrices in higher eukaryotes. These enzymes convert proline residues within the repeat regions of collagen polypeptides to 4-hydroxyproline, a modification essential for ...

QSOX2‐Mediated Disulfide Bond Modification Enhances Tumor Stemness and Chemoresistance by Activating TSC2/mTOR/c‐Myc Feedback Loop in Esophageal Squamous Cell Carcinoma

Advanced Science, EarlyView.
High QSOX2 enhances stemness, drug resistance, and metastasis of ESCC cells. QSOX2‐mediated disulfide bond modification activates mTOR/c‐Myc signaling. CAFs‐secreted IGF‐1 drives mTOR/c‐Myc/QSOX2 positive feedback loop. Combining Ebselen, rapamycin, and cisplatin induces tumor dormancy in mice.

A Genetically Encoded Homocysteine Precursor to Probe Protein Active Sites and to Addict Escherichia coli to a Noncanonical Amino Acid Directly Involved in Catalysis

Angewandte Chemie, EarlyView.
A new genetically encoded amino acid is chemically converted into homocysteine (Hcy) under mild conditions to probe and to activate protein active sites. Surprisingly, Hcy can replace cysteine or serine residues in several enzymes. Its potential for a widespread use in proteins is further underlined by rendering Escherichia coli dependent on Hcy ...

Inhibition of Phosphoglucose Isomerase [PDF]

Nature, 1956
THE key carbohydrate intermediate, glucose 6-phosphate, which may follow several alternative metabolic pathways including the 6-phosphogluconate oxidative cycle and the glycolytic sequence, enters the latter route by the phosphoglucose isomerase reaction.

Histone Demethylase UTX Suppresses Tumor Cell Proliferation by Regulating Stress Granules

Advanced Science, EarlyView.
These findings indicate that cytoplasmic UTX forms puncta and co‐localizes in stress granules (SGs) upon various stresses. UTX TPR‐domain‐dependently and demethylase‐activity‐independently destabilize SGs by binding G3BP1, the SG hub protein, to disrupt SG network, thus affects tumorigenesis.

Mitochondrial Thioredoxin System as a Modulator of Cyclophilin D Redox State [PDF]

, 2016
The mitochondrial thioredoxin system (NADPH, thioredoxin reductase, thioredoxin) is a major redox regulator. Here we have investigated the redox correlation between this system and the mitochondrial enzyme cyclophilin D.

A Complementarity‐Based Approach to De Novo Binder Design

Advanced Science, EarlyView.
A novel method for surface complementarity detection (HECTOR) enables highly efficient docking and design of protein interfaces. Applied to therapeutically relevant targets, this method yields de novo binders with potent antagonistic activity. As a first‐principles approach, HECTOR offers a training‐free solution to the binder design problem and is ...

Dual‐Targeted Nanovesicles Induced Cancer Stem‐Like Cell Differentiation to Sensitize Hepatocellular Carcinoma Radiotherapy

Advanced Science, EarlyView.
The existence of Pin1 and Notch1 crosstalk is identified and verified in HCC, and the crucial function of this crosstalk in sustaining the aggressive phenotypes of CSCs and radioresistance. A biomimetic nanovesicle is now developed to block the crosstalk between Pin1 and Notch1 for inducing CSCs differentiation and sensitizing HCC radiotherapy ...
