This study details the first successful orthotopic multi-organ xenotransplantation of a whole liver and bilateral kidneys from a six-gene-edited pig into a human decedent. Researchers utilized the "Sun" surgical technique for simultaneous implantation and reperfusion, maintaining graft stability and physiological function for approximately five days. High-dimensional profiling through single-cell ...去小宇宙查看完整单集简介

This research introduces patient-derived glioblastoma organoids (GBOs) as a powerful tool for advancing personalized medicine and improving clinical outcomes for brain cancer patients. These three-dimensional models effectively mirror the histopathological and genetic profiles of the original tumors, offering a more accurate representation than traditional cell cultures. The study demonstrates tha...去小宇宙查看完整单集简介

Researchers have developed SPACE-seq, a sophisticated platform that combines CRISPR-based lineage tracing with spatial transcriptomics to map cell ancestry and identity within native tissues. By utilizing DARLIN mouse models, this technology captures high-resolution data on how individual cells evolve and interact across space and time. The study demonstrates the tool's power by uncovering monoclo...去小宇宙查看完整单集简介

This research identifies IRG1-derived itaconate as a critical metabolic regulator that restricts lung cancer progression. By employing spatial metabolomics, the authors discovered that itaconate is naturally depleted within tumor regions, and its absence accelerates malignant growth and metastasis. Mechanistically, itaconate inhibits G6PD activity, which suppresses the pentose phosphate pathway an...去小宇宙查看完整单集简介

The research explores the critical link between the gut microbiota and the success of immune checkpoint blockade (ICB) in cancer treatment. It highlights how the presence of specific beneficial microbes and their metabolic byproducts, such as short-chain fatty acids, can enhance a patient's immune response against tumors. Conversely, factors like antibiotic use or a low-fiber diet can lead to micr...去小宇宙查看完整单集简介

This study introduces Mitotrek, a novel computational framework that utilizes mitochondrial DNA mutations to track the ancestral lineages of innate immune cells in cancer patients. By analyzing these genetic markers alongside chromatin accessibility, researchers discovered that the specialized roles of tumor-infiltrating monocytes are often predetermined in the blood before they even enter the tum...去小宇宙查看完整单集简介

Tang et al. establish a high-resolution prognostic atlas for pancreatic cancer by integrating single-nucleus transcriptomes with survival data from 152 patients. This study shifts the paradigm from traditional bulk-level analysis to cell-type-specific resolution, allowing researchers to link individual cell behaviors to clinical outcomes. The authors developed ctPANDA, an interactive web platform ...去小宇宙查看完整单集简介

Recent research indicates that colorectal cancer cells adopt oncofetal states resembling embryonic tissue long before metastasis occurs. This cellular plasticity is not driven by new genetic mutations but is instead triggered by the tumor microenvironment, specifically at the invasive front of early-stage lesions. Specialized cancer-associated fibroblasts, known as trophocyte-like CAFs, reside in ...去小宇宙查看完整单集简介

This paper discusses how colorectal cancer develops resistance to KRAS G12C inhibitors through complex genomic and transcriptomic shifts. Researchers found that tumors undergo epithelial cell plasticity, moving from a regenerative state to a Paneth or stem-like phenotype during treatment. This adaptation includes the emergence of pro-inflammatory pathways that persist even as the disease progresse...去小宇宙查看完整单集简介

Recent research indicates that pancreatic ductal adenocarcinoma, a typically treatment-resistant cancer, can be successfully managed by combining checkpoint blockade with STING-mediated immune stimulation. This study demonstrates that a triple therapy involving anti-PD-1, anti-CTLA-4, and a STING agonist triggers an unconventional immune response independent of the usual cytotoxic CD8+ T cells. In...去小宇宙查看完整单集简介
