Modulation of Bone Marrow Haematopoietic Stem Cell Activity as a Therapeutic Strategy After Myocardial Infarction: A Preclinical Study

Academic Background Myocardial Infarction (MI) is one of the major global health concerns. Although myeloid cells in the bone marrow (BM) are crucial for tissue repair after MI, excessive myelopoiesis can exacerbate scarring and impair cardiac function. Hematopoietic stem cells (HSCs) in the bone marrow possess unique regenerative capabilities, ena...

PRMT5-mediated arginine methylation stabilizes GPX4 to suppress ferroptosis in cancer

Background Introduction Ferroptosis is a form of cell death triggered by iron-dependent lipid peroxidation, which has recently been recognized as having significant potential in cancer therapy. Cancer cells evade ferroptosis through various molecular alterations and metabolic reprogramming mechanisms, with glutathione peroxidase 4 (GPX4) being a ke...

A Quantitative Ultrastructural Timeline of Nuclear Autophagy Reveals a Role for Dynamin-like Protein 1 at the Nuclear Envelope

Background Introduction The nuclear envelope (NE) is a critical barrier between the nucleus and the cytoplasm, responsible for maintaining the stability of the nuclear environment. The integrity of the nuclear envelope is essential for normal cellular function, and its disruption is closely linked to aging and various diseases. Autophagy is a vital...

ADSL-Generated Fumarate Binds and Inhibits STING to Promote Tumour Immune Evasion

Research Background In the tumor microenvironment, highly aggressive tumors evade immune system attacks by suppressing the cGAS-STING signaling pathway. The cGAS-STING pathway is a critical mechanism for cells to sense cytoplasmic double-stranded DNA and initiate immune responses. cGAS (cyclic GMP-AMP synthase) catalyzes the production of cGAMP upo...

Multipotent Neural Stem Cells Originating from Neuroepithelium Exist Outside the Mouse Central Nervous System

Background Introduction For a long time, the scientific community has generally believed that mammalian neural stem cells (NSCs) exist only in the central nervous system (CNS), particularly in specific regions of the brain, such as the dentate gyrus of the hippocampus and the subventricular zone near the lateral ventricles. NSCs in these regions ca...

RPL12 is a Conserved Ribophagy Receptor

Academic Background Ribophagy is a selective autophagy process responsible for regulating the degradation and turnover of ribosomes. Ribosomes are the core machinery for protein synthesis in cells, and their synthesis and degradation are crucial for cellular adaptation to environmental changes, such as nutrient deprivation. Under nutrient-rich cond...

ER-to-Golgi Trafficking Through a Dynamic Intermediate Cis-Golgi Tubular Network in Arabidopsis

Academic Background In eukaryotic cells, the transport from the endoplasmic reticulum (ER) to the Golgi apparatus is a central process of the secretory system, responsible for the spatiotemporal sorting of proteins and lipids. However, the nature of the ER-Golgi intermediate compartment (ERGIC) and the molecular mechanisms mediating the transition ...

Proteostasis and Lysosomal Repair Deficits in Transdifferentiated Neurons of Alzheimer’s Disease

Academic Background Alzheimer’s disease (AD) is the most common neurodegenerative disorder among the elderly, characterized by the pathological features of amyloid-beta (Aβ) deposits and hyperphosphorylated tau protein. Although aging is the most prominent risk factor for AD, the cellular mechanisms linking the decline in neuronal proteostasis to t...

Discovery of Large Extracellular Vesicles Blebbisomes and Their Functional Study

Academic Background Extracellular vesicles (EVs) are crucial mediators of intercellular communication, carrying proteins, lipids, and genetic information to participate in various physiological and pathological processes. However, our understanding of EVs remains incomplete, particularly regarding the study of exceptionally large EVs. To address th...

Growth Factor-Triggered De-Sialylation Controls Glycolipid-Lectin-Driven Endocytosis

In cell biology, the glycosylation modification of cell surface glycoproteins plays a crucial role in processes such as cell signaling, adhesion, and migration. How dynamic changes in glycosylation regulate intracellular transport and function, particularly the internalization of cell surface receptors through endocytosis, remains an incompletely u...
