Critical Role of the Potential O-Linked Glycosylation Sites of CXCR4 in Cell Migration and Bone Marrow Homing of Hematopoietic Stem Progenitor Cells

1. Academic Background and Research Origin Hematopoietic stem/progenitor cells (HSPCs) are the foundation for maintaining the steady state of the adult blood system. Every day, the human body needs to generate billions of new blood cells—a process that relies on the capacity of HSPCs for self-renewal and directed differentiation within the bone mar...

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...

N-acetylglucosaminyltransferase V drives colorectal cancer metastasis by facilitating ZO-1 ubiquitination and degradation

N-acetylglucosaminyltransferase V drives colorectal cancer metastasis by facilitating ZO-1 ubiquitination and degradation

In a recent study published in “Cancer Cell International,” Yueping Zhan and others explored the role of N-acetylglucosaminyltransferase V (MGAT5) in colorectal cancer (CRC) and its mechanism in promoting cancer cell metastasis. The publication of this paper is driven by the urgent need to study CRC due to its high mortality and metastatic characte...

Distinct Patterns of Plaque and Microglia Glycosylation in Alzheimer’s Disease

Distinct Patterns of Plaque and Microglia Glycosylation in Alzheimer’s Disease

Unique Patterns of Glycosylation in Plaques and Microglia in Alzheimer’s Disease Research Background Alzheimer’s disease (AD) is the most common form of dementia and a devastating neurodegenerative disorder. AD is characterized by two pathological features: extracellular β-amyloid (Aβ) plaques and intracellular phosphorylated Tau neurofibrillary ta...
