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...

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...

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) ...

Spatially Segregated Macrophage Populations Predict Distinct Outcomes in Colon Cancer

Spatially Segregated Macrophage Populations Predict Distinct Outcomes in Colon Cancer

Spatially Isolated Macrophage Populations Predict Different Outcomes in Colon Cancer Introduction Macrophages are sentinel immune cells in tissues, performing a variety of functions including pathogen defense, antigen presentation, phagocytosis of dead cells, and the secretion of signals that drive tissue repair. In tumors, macrophage infiltration ...

Bidirectional Epigenetic Editing Reveals Hierarchies in Gene Regulation

Bidirectional Epigenetic Editing Reveals Hierarchies in Gene Regulation Background and Research Motivation In the human genome, the role of non-coding elements such as enhancers in gene regulation is widely recognized. However, current CRISPR interference methods still have some limitations in studying non-coding elements and genetic interactions. ...

Multiplex Cerebrospinal Fluid Proteomics Identifies Biomarkers for Diagnosis and Prediction of Alzheimer's Disease

Cerebrospinal Fluid Proteomics Study for Diagnosis and Prediction of Alzheimer’s Disease Background and Research Objectives Alzheimer’s disease (AD) is a neurodegenerative disease that leads to memory loss and cognitive decline, and currently, there is no effective cure globally. Traditionally, the pathological features of AD include β-amyloid (Aβ)...

CRISPRi-based Circuits to Control Gene Expression in Plants

CRISPRi-based Circuits to Control Gene Expression in Plants

Academic Background In the field of plant biotechnology, traditional gene manipulation methods focus on producing the desired phenotypes and cellular activities through continuous transgene expression. However, strong continuous promoters may lead to gene silencing, metabolic burdens, or other adverse effects on yield, preventing the full realizati...

Generation of Allogeneic CAR-NKT Cells from Hematopoietic Stem and Progenitor Cells Using a Clinically Guided Culture Method

Generation of Clinically Applicable CAR-NKT Cells Research Background Chimeric Antigen Receptor (CAR) T cell therapy has been approved by the Food and Drug Administration (FDA) for the treatment of B-cell malignancies and multiple myeloma. However, the use of autologous CAR-T cell products presents challenges such as high costs, long manufacturing ...
