Summary
This summary is machine-generated.Integrin β5 (ITGB5) promotes tongue squamous cell carcinoma (TSCC) metastasis. Targeting ITGB5 or reactive oxygen species (ROS) may inhibit TSCC spread and improve patient prognosis.
Area Of Science
- Oncology
- Molecular Biology
- Cell Biology
Background
- Integrin β5 (ITGB5) is implicated in tumor metastasis.
- Its role in tongue squamous cell carcinoma (TSCC) requires further investigation.
Purpose Of The Study
- To investigate the differential expression of ITGB5 in TSCC, particularly in relation to lymph node metastasis.
- To elucidate the underlying mechanisms by which ITGB5 influences TSCC progression.
Main Methods
- Analysis of ITGB5 expression in 135 TSCC patient tissues using immunohistochemistry.
- In vitro studies involving ITGB5 knockdown and overexpression in TSCC cells.
- Exploration of reactive oxygen species (ROS) and epithelial-mesenchymal transition (EMT) in relation to ITGB5.
Main Results
- ITGB5 expression was significantly higher in TSCC tissues than adjacent tissues and correlated with lymph node metastasis.
- High ITGB5 expression predicted a worse prognosis.
- ITGB5 promoted TSCC cell invasion and migration; ROS enhanced ITGB5 expression, driving metastasis via the cell adhesion pathway.
Conclusions
- Increased ITGB5 expression in TSCC is associated with lymph node metastasis and poor prognosis.
- ITGB5 may serve as a potential biomarker for metastasis and prognosis in TSCC.
- Targeting ITGB5 or ROS presents a potential therapeutic strategy against TSCC metastasis.

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
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...
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.
The mTOR pathway or the...
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.

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
