CRISPR dependency screens in primary hematopoietic stem cells identify KDM3B as a genotype-specific vulnerability in IDH2- and TET2-mutant cells

CRISPR-Dependent Screening in Primary Hematopoietic Stem Cells Identifies KDM3B as Specific Susceptibility for IDH2 and TET2 Mutant Genotypes Background and Significance Clonal Hematopoiesis (CH) refers to the abnormal growth of genetically distinct subclones of cells initiated by specific mutations in Hematopoietic Stem Cells (HSCs). This phenomen...

Mechanisms of Resistance to Oncogenic KRAS Inhibition in Pancreatic Cancer

Mechanisms of Resistance to Carcinogenic KRAS Inhibition in Pancreatic Cancer Background Pancreatic Ductal Adenocarcinoma (PDAC) is a highly lethal disease. Most patients are diagnosed at an advanced stage and typically die within 12 months, primarily due to limited treatment options and poor response to standard chemotherapy. KRAS is the most crit...

Clinical Validation of a Cell-Free DNA Fragmentome Assay for Augmentation of Lung Cancer Early Detection

Clinical Validation Study on the Application of Cell-Free DNA Fragment Analysis in Enhancing Early Detection of Lung Cancer Background Lung cancer is one of the leading types of cancer threatening the health of both men and women globally. Over 125,000 people die from lung cancer in the United States each year, and globally, the number is close to ...

Targeting Acute Myeloid Leukemia Stem Cells Through Perturbation of Mitochondrial Calcium

Targeting Acute Myeloid Leukemia Stem Cells Through Perturbation of Mitochondrial Calcium

This is an academic paper report on the study of acute myeloid leukemia (AML) stem cells. The study found that venetoclax treatment targeting the BCL-2 protein induces different mitochondrial calcium signaling changes in drug-sensitive and drug-resistant AML stem cells, thereby affecting their oxidative phosphorylation metabolism and survival. The ...

Mechanisms of Response and Tolerance to Active RAS Inhibition in KRAS-Mutant NSCLC

Response and Resistance Mechanisms of RAS Inhibitors in KRAS-Mutant NSCLC Research Background With the clinical development of RAS inhibitors, the treatment of KRAS-mutant Non-Small Cell Lung Cancer (NSCLC) faces a new turning point. However, in clinical practice, patients show poor long-term responses to RAS inhibitors, influencing clinical effica...

Clonal Lineage Tracing with Recordable Barcodes Reveals Migration Histories of Metastatic Prostate Cancer

Gargiulo, Lucrezia Patruno, Caroline L. Buckholtz, Ryan J. Chaffee, Megan C. Jibilian, Steven G. Persaud, Stephen J. Staklinski, Rebecca Hassett, Lise M. Brault, ...

Activating Point Mutations in the MET Kinase Domain Represent a Unique Molecular Subset of Lung Cancer and Other Malignancies Targetable with MET Inhibitors

This study reveals a new targetable cancer subtype characterized by activating point mutations in the MET tyrosine kinase domain (TKD). Researchers identified MET TKD activating mutations in approximately 0.5% of patients across a genomic data set of over 600,000 cancer cases, encompassing various tumor types, with the highest prevalence in renal c...

Iron-(Fe3+)-Dependent Reactivation of Telomerase Drives Colorectal Cancers

Iron-(Fe3+)-Dependent Reactivation of Telomerase Drives Colorectal Cancers

Iron (Ferric Ion, Fe3+)-Dependent Telomerase Reactivation Drives Colorectal Cancer Development I. Research Background Colorectal Cancer (CRC) is the third most common cancer globally, involving both genetic and non-genetic factors in its pathogenesis. Existing research shows a significant association between high iron content, hereditary iron overl...

High-Throughput Discovery of MHC Class I- and II-Restricted T Cell Epitopes Using Synthetic Cellular Circuits

High-Throughput Discovery of MHC Class I and II Restricted T Cell Epitopes Using a Novel Synthetic Cellular Circuit Research Background and Issues In recent years, antigen discovery technologies have made remarkable progress, especially in the application of human T-cell receptors (TCRs) in the recognition of major histocompatibility complex (MHC) ...
