Cancer stem cells synthesize proline to attenuate oxidative stress

The Journal of Clinical Investigation
Cancers reprogram their metabolism to provide anabolic needs without driving excessive oxidative stress. Attention has focused on glucose metabolism, yet amino acid synthesis and degradation also promote tumor cell states and growth.

VCP‐Regulated LMF2 Stabilizes the Cholesterol Biosynthesis Enzyme HMGCS1 to Drive Cancer Progression and Confer Capecitabine Resistance in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
LMF2 drives progression and capecitabine resistance in triple‐negative breast cancer (TNBC). Mechanistically, VCP prevents NBR1‐mediated autophagic degradation of LMF2, thereby stabilizing it. Stabilized LMF2 subsequently suppresses NDP52‐mediated autophagic degradation of HMGCS1, a rate‐limiting cholesterol biosynthesis enzyme.

Molecular Glue Degraders of TEM β‐Lactamases by Periplasmic Protease DegP

Angewandte Chemie, EarlyView.
Molecular glues are developed that target TEM‐family β‐lactamases to the bacterial protease DegP for degradation. β‐Lactamase inhibitor tazobactam is identified as accelerating TEM β‐lactamase degradation by DegP, which is further enhanced by linkerless incorporation of dipeptides enriched among DegP substrates.

ZMIZ2–DUX4–LGR5 Signaling Axis Maintains Stemness Properties and Facilitates Docetaxel Resistance in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
This study identifies ZMIZ2 as a therapeutic target for docetaxel‐resistant triple‐negative breast cancer, sustaining cancer stemness‐associated properties and docetaxel resistance. ZMIZ2 upregulation enhances DUX4‐mediated LGR5 activation through the SWI/SNF components BRG1 and BAF57.

Mechanisms by which proline reductase of Clostridioides difficile promotes efficient metabolism and disease progression in vivo

mBio
Clostridioides difficile is a toxin-producing pathogen that opportunistically infects those with a depleted gut microbiome, often triggered by antibiotic use. C.

A Fluorogenic Cysteine‐Tetrapeptide Tagging Strategy for Nonperturbative Protein Labeling and Protein–Ligand Interaction Tracking

Advanced Science, EarlyView.
A compact Phe‐Cys‐Pro‐Phe (FCPF) tag and an environment‐sensitive SBD‐Cl‐derived probe form a sequence‐selective fluorogenic pair for wash‐free live‐cell protein imaging. This minimally perturbing chemistry allows flexible insertion at termini or loops, produces strong fluorescence upon local microenvironment confinement, supports FRET‐assisted ...

Multifaceted effects of proline on intestinal injury, inflammation, and lipid metabolism in piglets induced by porcine epidemic diarrhea virus

Amino Acids
This study investigated the effects of proline on intestinal injury in piglets infected with porcine epidemic diarrhea virus (PEDV). Twenty-eight 7-day-old piglets were assigned to four groups: control (CON), proline (Pro), PEDV, and Pro + PEDV.

DTX3 Suppresses the NPM3–RUVBL1 Axis to Inhibit Homologous Recombination Repair and Abrogate Tumor Radioresistance

Advanced Science, EarlyView.
Deltex 3 (DTX3) catalyzes K27‐linked ubiquitination of nucleophosmin 3 to disrupt homologous recombination repair and reverse tumor radioresistance. Low DTX3 predicts poor survival and radiotherapy recurrence, serving as a radiosensitizing therapeutic target.

PHGDH‐Mediated Serine Metabolism in Nucleus Pulposus Cells Is a Potential Therapeutic Target for Intervertebral Disc Degeneration

Advanced Science, EarlyView.
When nucleus pulposus cells senesce, PHGDH decreases, reducing serine synthesis and glutathione, impairing antioxidant capacity. The intermediate α‐KG also drops, lowering JMJD3 demethylase activity, increasing H3K27me3 at the Rap1b promoter, and reducing Rap1b expression, whose down‐regulation in turn activates mTORC1 and suppresses autophagy ...

Interleukin‐18 signaling promotes activation of hepatic stellate cells in mouse liver fibrosis

Hepatology, EarlyView., 2022
Interleukin‐18 signaling promotes activation of hepatic stellate cells in mouse liver fibrosis. Abstract Background and Aims Nucleotide‐binding oligomerization domain‐like receptor‐family pyrin domain‐containing 3 (NLRP3) inflammasome activation has been shown to result in liver fibrosis.
