Topological barrier to Cas12a activation by circular DNA nanostructures facilitates autocatalysis and transforms DNA/RNA sensing

Nature Communications
Control of CRISPR/Cas12a trans-cleavage is crucial for biosensor development. Here, we show that small circular DNA nanostructures which partially match guide RNA sequences only minimally activate Cas12a ribonucleoproteins.

Transfer RNA‐Derived Small RNA‐5’tiRNAGln Drives HNRNPC Phase Separation to Promote Breast Cancer Bone Metastasis by Regulating IGF1R

Advanced Science, EarlyView.
This study reveals that 5'tiRNA‐Gln interacts with hnRNPC to promote IGF1R liquid‐liquid phase separation, which drives ERK1/2 signaling activation, EMT, and breast cancer bone metastasis. These findings highlight a novel mechanism of breast cancer bone metastasis and potential therapeutic target in metastatic breast cancer.

Accessibility and Alignment of Trans‐Cleavage Substrates Modulate the Kinetics of Cas12a Ribonucleoprotein

Angewandte Chemie, EarlyView.
Two key binding events that collectively determine the catalytic efficiency of trans‐cleavage: (1) the substrate passing through the gap between the REC and NUC domains, determined by Kpass, and (2) the alignment of the substrate with the catalytic triad of the ribonucleoprotein, determined by Kalign.

CXCL3 Antagonism Reverses Systemic Antitumor Immune Memory Impairment Associated With High Tumor Burden and Sensitizes Anti‐PD‐1 Therapy

Advanced Science, EarlyView.
This study reveals that large tumors secrete more chemokine CXCL3, which recruits immunosuppressive neutrophils to the periphery, thereby impairing the activation and memory of systemic tumor‑reactive CD8+ T cells. CXCL3 antagonism restores systemic immune memory and enhances the antitumor efficacy of anti‑PD‑1 therapy, offering a potential strategy to

Decoding Biomolecular Phase Separation: From Physiological Roles to Pathological Mechanisms and Therapeutic Biomaterials Design

Advanced Science, EarlyView.
This review systematically elaborates on the mechanisms underlying physiological regulation and pathological dysregulation of biomolecular phase separation. It also summarizes advances in phase‑separation‑targeted therapeutic strategies and the design of functional biomaterials inspired by this process.

RBMS1 Contributes to Early Arteriovenous Fistula Neointimal Remodeling Through Modulation of VSMC Phenotypic Responses

Advanced Science, EarlyView.
Postoperative arteriovenous fistulas exhibit increased RBMS1 in vascular smooth muscle cells (VSMCs). In experimental AVFs, RBMS1 overexpression aggravates, whereas deletion attenuates, neointimal hyperplasia. RBMS1 binds MPZL1 mRNA and promotes exon 5 skipping to generate MPZL1‐Δ5, which interacts with G3BP1 to activate AKT, driving VSMC proliferation,

Small ribonucleoproteins from eukaryotes: structures and roles in RNA biogenesis

, 1983
Only recently have the many and varied types of small ribonucleoproteins (RNPs) resident in mammalian cells become accessible to analysis. These entities--defined as tight complexes of one or more proteins with a small RNA molecule (up to about 300 ...

Packaged delivery of CRISPR–Cas9 ribonucleoproteins accelerates genome editing [PDF]

Effective genome editing requires a sufficient dose of CRISPR-Cas9 ribonucleoproteins (RNPs) to enter the target cell while minimizing immune responses, off-target editing, and cytotoxicity.

Musculoskeletal Phenotypes of 19 Patients With X‐Linked HNRNPH2‐Related Neurodevelopmental Disorder: A Prospective Case Series

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Detailed clinical phenotypes have been previously reported for 33 individuals with X‐linked HNRNPH2‐related neurodevelopmental disorder. Of these, 75% self‐reported a musculoskeletal abnormality, including hip dysplasia, scoliosis, kyphosis, lordosis, pes planus, arthritis, and missing spinous processes.

Biallelic PIGB Variants Cause Motor Neuropathy with Conduction Blocks and Peripheral Nerve Hyperexcitability

Annals of Neurology, EarlyView.
Objective Glycosylphosphatidylinositol (GPI)‐anchored proteins play critical roles in nervous system function. Pathogenic variants in genes involved in GPI‐anchor biosynthesis cause early‐onset multisystem disorders known as inherited GPI deficiencies. We describe a novel neuromuscular phenotype associated with PIGB deficiency.
