Biochemical Characterization of Two Streptococcus Anti-CRISPR Proteins

, 2023
One of the greatest threats to bacterial survival are bacteriophages, viruses that infect and kill host bacteria. As defence, bacteria have evolved CRISPR-Cas systems, which are complexes of RNA and proteins that funcNon as adapNve immune systems to ...

The AUTACE That Degrades KRAS and Engages CD8+ T Cells for the Treatment of KRAS/TP53 Co‐Mutant Tumors

Advanced Science, EarlyView.
AUTACE is a bifunctional nanoplatform that integrates tumor targeting, immune engagement, and on‐demand KRAS degradation. It targets KRAS/TP53 co‐mutant tumors via TP53‐specific TCRs, elicits antitumor CD8+ T‐cell responses through surface anti‐CD3 antibodies, and uses low‐intensity focused ultrasound (LIFU) to trigger controlled release of the KRAS ...

Inhibition of SIRT7 Overcomes Radioresistance in Pancreatic Neuroendocrine Tumors by Reactivating MEN1 Expression

Advanced Science, EarlyView.
Pancreatic neuroendocrine tumors frequently silence MEN1 through epigenetic mechanisms. Here, SIRT7 recruits DNMT1 to the MEN1 promoter, drives hypermethylation, and enhances DNA repair. Inhibiting SIRT7 restores MEN1, reduces MRN complex abundance, impairs double‐strand break repair, and sensitizes PanNET models to radiation, supporting SIRT7 as a ...

G3BP1 Succinylation at K413 is Critical for Cardiac Function by Modulating PI3K‐AKT‐mTOR Signal Axis

Advanced Science, EarlyView.
Schematic illustrating the impact of G3BP1 succinylation at K413 on cardiac function. In the healthy human heart, G3BP1 succinylation maintains homeostatic mTOR signaling. In patients with dilated cardiomyopathy (DCM) and heart failure (HF), G3BP1 de‐succinylation induces RagA expression and disrupts the binding of the TSC1/2 complex, leading to the ...

eQTL Meta‐Analysis Reveals Conserved and Population‐Specific Regulatory Variation Underlying Nutritional Trait Evolution and Domestication in Tomato

Advanced Science, EarlyView.
A comprehensive meta‐analysis of expression quantitative trait loci (eQTLs) across five diverse tomato populations reveals a high‐resolution atlas of transcriptional regulation and uncovers conserved and population‐specific regulatory architectures underlying fruit nutritional quality traits, including flavonoids, sugars, organic acids, carotenoids ...

A Microbial Lipid‐ATP Synthase Axis Fuels NK Cell Antitumor Activity

Advanced Science, EarlyView.
This study focuses on the mechanism by which gut microbiota‐derived outer membrane vesicles (OMVs) regulate NK cell antitumor activity. B. intestinalis is identified to decrease extra‐intestinal tumor growth via its OMVs enriched in sphingosine (SP).

HNRNPU K181 Lactylation Drives Cervical Cancer Growth by Upregulating PHGDH and Reprogramming Serine Metabolism

Advanced Science, EarlyView.
Lactate in cervical cancer induces HNRNPU K181 lactylation, opposed by NAA50‐mediated acetylation and suppressed by Pazopanib. This lactylation enhances HNRNPU binding to PHGDH pre‐mRNA exon 1, maintaining exon 1‐containing transcripts and mRNA stability, thereby activating serine metabolism.

Programmable mammalian translational modulators by CRISPR-associated proteins

Programmable mammalian translational modulators by CRISPR-associated proteins
Translational modulation based on RNA-binding proteins can be used to construct artificial gene circuits, but RNA-binding proteins capable of regulating translation efficiently and orthogonally remain scarce. Here we report CARTRIDGE (Cas-Responsive Translational Regulation Integratable into Diverse Gene control) to repurpose Cas proteins as ...

Molecular Glue cc‐885 Inhibits VHL‐Deficient Clear Cell Renal Cell Carcinoma via ETS1 Degradation

Advanced Science, EarlyView.
VHL‐deficient kidney cancer lacks effective treatments. This study reveals that the molecular glue degrader cc‐885 hijacks the cellular recycling system to selectively destroy the oncogenic protein ETS1, effectively killing VHL‐mutant tumors. Combining CC‐885 with the approved drug belzutifan achieves powerful synergy, offering a promising new ...

TSPYL5 Promotes Triple‐Negative Breast Cancer Metastasis by Antagonizing USP10‐Mediated PTEN Stabilization to Unleash a ZEB1‐Dependent EMT Program

Advanced Science, EarlyView.
The hyperactivation of PI3K/AKT signaling in PTEN wild‐type triple‐negative breast cancer represents a clinical paradox. We delineate a novel post‐translational regulatory axis wherein the oncogene TSPYL5 competitively antagonizes the deubiquitinase USP10.
