Summary
Kinesin family member 4A (KIF4A) promotes glioma cell growth and spread. Targeting KIF4A may offer a new strategy for treating aggressive brain tumors by affecting epithelial-mesenchymal transition.
Area of Science:
- Neuro-oncology
- Molecular Biology
- Cancer Research
Background:
- Gliomas are primary brain tumors with poor prognosis, especially high-grade types.
- Kinesin family member 4A (KIF4A) is implicated in tumor cell proliferation, migration, and invasion.
- The specific role of KIF4A in glioma progression remains unclear.
Purpose of the Study:
- To investigate the impact of KIF4A on epithelial-mesenchymal transition and invasion in glioma cells.
- To identify KIF4A-associated signaling pathways and downstream targets in glioma.
Main Methods:
- Analysis of The Cancer Genome Atlas and Chinese Glioma Genome Atlas data for KIF4A expression.
- In vitro validation using western blotting, transwell assays, and wound-healing scratch assays in U251 and U87 cells.
- Gene Ontology and Gene Set Enrichment Analysis to identify signaling pathways.
Main Results:
- Elevated KIF4A expression in gliomas correlated with clinical grade.
- KIF4A overexpression enhanced glioma cell migration, invasion, and proliferation; knockdown had opposite effects.
- KIF4A positively regulates TGF-β/SMAD signaling and transcriptionally controls benzimidazoles-1 expression.
Conclusions:
- KIF4A promotes glioma cell epithelial-mesenchymal transition and invasion.
- KIF4A regulates the TGF-β/SMAD pathway via benzimidazoles-1 in glioma.
- KIF4A represents a potential therapeutic target for glioma treatment.

7.4K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

01:22PI3K/mTOR/AKT Signaling Pathway
3.6K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

03:03mTOR Signaling and Cancer Progression
3.8K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

02:17The Tumor Microenvironment
6.6K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

01:24Regulation of Angiogenesis and Blood Supply
2.6K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

01:17Intracellular Signaling Affects Focal Adhesions
2.7K
Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.
