Decoding Heterogeneous Single-Cell Perturbation Responses

Background Introduction In cell biology, understanding how cells respond differently to perturbations is crucial. Perturbation refers to altering cell states through gene editing, chemical substances, environmental changes, or mechanical forces to study their functions. However, existing methods have limitations in quantifying heterogeneous respons...

Selective Translational Control by PABPC1 Phase Separation Regulates Blast Crisis and Therapy Resistance in Chronic Myeloid Leukaemia

Academic Background and Problem Introduction Chronic Myeloid Leukemia (CML) is a hematologic malignancy driven by the BCR-ABL1 fusion gene. Although Tyrosine Kinase Inhibitors (TKIs) have significantly improved the survival rate of CML patients, TKI resistance and disease progression to the blast crisis (BC) phase remain major challenges in clinica...

Intratumour Oxidative Hotspots Provide a Niche for Cancer Cell Dissemination

Tumor heterogeneity is a critical issue in cancer research, encompassing genetic, phenotypic, and microenvironmental heterogeneity. Although single-cell sequencing has shed light on genetic and phenotypic heterogeneity, the study of non-genetic factors, such as microenvironmental heterogeneity, remains insufficient. Oxidative stress is a hallmark o...

Systematic Reconstruction of Molecular Pathway Signatures Using Scalable Single-Cell Perturbation Screens

In the field of functional genomics, researchers have long been dedicated to predicting causal regulatory relationships from observational data. However, despite modern technologies enabling the measurement of diverse molecular modalities, inferring causal regulatory relationships from observational data remains challenging. In particular, the iden...

Functional Screen Identifies RBM42 as a Mediator of Oncogenic mRNA Translation Specificity

The occurrence and progression of cancer are closely related to the expression of oncogenes, and the regulation of oncogene expression is a complex process. Among these mechanisms, the role of translation control in oncogene expression has gradually gained attention. MYC is a key oncogene that is overexpressed in various cancers, particularly in pa...

Coupling of Cell Shape, Matrix and Tissue Dynamics Ensures Embryonic Patterning Robustness

Research Background During the early stages of mammalian embryonic development, embryonic cells gradually differentiate into various cell types through complex regulatory mechanisms, forming tissues with specific functions. This process is known as tissue patterning, which involves the determination of cell fate, coordination of cellular dynamics, ...

Spectinomycin-Loaded Antibacterial Polyvinyl Alcohol/Silver Oxide Nanobiocomposite Hydrogel: Synthesis, Characterization, Swelling, Cytotoxicity, and Controlled Drug Release Carrier

Academic Background In the field of drug delivery, achieving long-term and controlled release of drugs is a significant research direction. Hydrogels, as materials with excellent biocompatibility and degradability, have been widely used in drug delivery, tissue engineering, and wound dressing. However, the low mechanical strength of traditional hyd...

Pseudomonas fluorescens–Based Biogenic Silver Nanoparticles: A Green Solution for Brown Leaf Spot Disease in Rice

Academic Background Rice (Oryza sativa L.) is a globally important food crop, providing a primary source of calories for approximately one-fifth of the world’s population. However, rice production faces various biotic and abiotic stresses, leading to reduced yields. Among these, rice brown leaf spot disease, caused by the fungal pathogen Cochliobol...

Development and Characterization of Baricitinib Nanoemulgel with Antiarthritic Effect in Rats

Academic Background Rheumatoid Arthritis (RA) is a chronic autoimmune disease that primarily affects the synovial membrane of joints, leading to inflammation and erosive lesions. Approximately 0.5% to 1% of the global population is affected by this disease, particularly among the elderly, who often experience dysphagia, which limits the compliance ...

Synthesis and Characterization of Pyrogallol Silver Nanoparticles and Pyrogallol Nanocomposites and Their Effects on Radiation-Induced Toxicity in HEK293 Cells

Academic Background Cancer is a complex and highly prevalent disease worldwide, causing nearly 10 million deaths annually. Early diagnosis and effective treatment are crucial for improving patient survival rates. Current cancer treatment modalities include surgery, chemotherapy, radiotherapy, and immunotherapy. Among these, radiotherapy is a critic...
