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, ...

Endothelial Cells Stably Infected with Recombinant Kaposi’s Sarcoma-Associated Herpesvirus Display Distinct Viscoelastic and Morphological Properties

Kaposi’s sarcoma-associated herpesvirus (KSHV) is a γ-herpesvirus that primarily infects endothelial cells and leads to the development of Kaposi’s sarcoma (KS), especially in people living with HIV. Kaposi’s sarcoma is a malignant tumor characterized by endothelial cell proliferation, typically presenting as cutaneous lesions. After infecting endo...

Acteoside-Loaded Self-Healing Hydrogel Enhances Skin Wound Healing through Modulation of Hair Follicle Stem Cells

Skin wound healing is a complex biological process involving the coordination of cellular, molecular, and physiological events. Although traditional treatment methods can promote wound closure to some extent, their efficacy is often unsatisfactory in chronic wounds or complex trauma environments, particularly in controlling infections and inflammat...

CRISPR-dCas9 Activation of TSG-6 in MSCs Modulates the Cargo of MSC-Derived Extracellular Vesicles and Attenuates Inflammatory Responses in Human Intervertebral Disc Cells In Vitro

Intervertebral Disc Degeneration (IVDD) is one of the leading causes of low back pain worldwide, significantly impacting patients’ quality of life. IVDD is often accompanied by inflammatory responses, leading to the degradation of the extracellular matrix (ECM) and structural damage. Although cell therapies, such as mesenchymal stem cells (MSCs), h...
