Programmable RNA targeting with clustered regularly interspaced short palindromic repeats (CRISPR) effector Cas7-11 in zebrafish embryos and mammalian cells

<title>Abstract</title> <bold>Background</bold> The CRISPR/Cas7-11 system is a recently characterized RNA editing tool that exhibits low toxicity, minimal off-target effects, and reduced collateral RNA cleavage compared with existing methods. Although zebrafish and human embryoni...

siRNA-mediated mismatch repair disruption synergizes with oxaliplatin to restore immune surveillance in microsatellite-stable colorectal cancer

Proficient mismatch repair/microsatellite-stable colorectal cancer (pMMR/MSS CRC), which represents the majority of clinical cases, exhibits low tumor mutational burden and minimal responsiveness to immune checkpoint blockade. Disrupting the MMR system has been shown to resensiti...

TCGA-based identification and functional validation of PBK in intrahepatic cholangiocarcinoma progression with involvement of AKT signaling

Intrahepatic cholangiocarcinoma (ICC) is an aggressive malignancy with limited molecular targets. This study aimed to identify candidate genes involved in ICC progression and to examine the functional role of PBK. Integrated bioinformatics analysis was performed on TCGA-CHOL data...

ABHD11-Mediated mtDNA Transcription Restored Mitochondrial Function to Attenuate Cardiomyocyte Ferroptosis After Myocardial Infarction

BACKGROUND: Cardiomyocytes exhibit marked susceptibility to ferroptosis after myocardial infarction (MI), rendering ferroptosis inhibition a promising therapeutic strategy to mitigate ischemic myocardial injury. Although mitochondrial dysfunction is recognized as a core driver of...

From predictive model to clinical application: interpretable prediction of metachronous liver metastasis in colorectal cancer

Metachronous liver metastasis (MLM) after curative surgery is a major determinant of poor prognosis in colorectal cancer (CRC), yet existing approaches based on clinicopathological indicators or imaging alone have limited predictive performance and clinical applicability. This re...

Roles of cerebrospinal fluid metabolites in neuromyelitis optica spectrum disorder: Insights from Mendelian randomization

Neuromyelitis optica spectrum disorder (NMOSD) is a rare multifocal inflammatory disease that primarily affects the optic nerve and spinal cord, leading to visual loss and paralysis. Although current research has identified numerous biomarker changes in the cerebrospinal fluid (C...

Targeted uterine artery infusion of bone marrow-derived mesenchymal stem cells for severe intrauterine adhesions: a randomized controlled trial with exploratory translational analyses

Severe intrauterine adhesions (IUA) represent a profound failure of endometrial regeneration, characterized by excessive fibrosis and vascular insufficiency. Mesenchymal stem cell-based therapies show regenerative potential, but clinical evidence is inconsistent, and optimal deli...

The VASN-YAP-MYL9 axis drives M2-like macrophage polarization and immune evasion in colorectal cancer

Tumor-associated macrophages (TAMs) polarized toward an M2-like phenotype are critical drivers of immunosuppression in colorectal cancer (CRC). While Vasorin (VASN) is implicated in poor prognosis, its specific role in orchestrating the tumor immune microenvironment remains elusi...
