Summary
Tensins (TNS1-4) link cell structure to signaling, acting as tumor promoters or suppressors. Tensin-4 (TNS4) uniquely drives cancer progression by stabilizing EGFR, highlighting its therapeutic potential.
Area of Science:
- Molecular Cell Biology
- Cancer Biology
- Biochemistry
Background:
- Tensins (TNS1-4) are key scaffolds connecting the actin cytoskeleton to integrin adhesions.
- They regulate signal transduction and cellular processes critical in cancer development.
Purpose of the Study:
- To review the structural, functional, and clinical roles of tensins in cancer.
- To highlight the context-dependent functions of TNS1-3 versus the oncogenic role of TNS4.
- To explore TNS4's therapeutic potential.
Main Methods:
- Literature review synthesizing structural, functional, and clinical data on tensins.
- Analysis of tensin roles in cell adhesion, cytoskeleton dynamics, and signal transduction pathways.
- Correlation of tensin dysregulation with cancer progression and patient prognosis.
Main Results:
- TNS1-3 possess an N-terminal actin-binding domain (ABD) involved in cytoskeletal regulation and context-dependent tumor promotion/suppression.
- TNS4 lacks an ABD and acts as a focal adhesion signal amplifier, stabilizing EGFR and promoting cancer progression.
- Tensin dysregulation, particularly TNS4, is linked to metastasis, poor prognosis, and serves as a diagnostic/prognostic biomarker.
Conclusions:
- Tensins exhibit diverse roles in cancer, with TNS1-3 showing context-dependent functions and TNS4 acting as a consistent oncoprotein.
- TNS4's role in stabilizing EGFR and driving cancer hallmarks presents a potential therapeutic target.
- Understanding tensin family dynamics is crucial for cancer diagnosis, prognosis, and targeted therapy development.

01:15Activation of Integrins
3.6K
Integrins bind ligands and transmit information from outside the cell to inside or vice-versa through an "outside-in signaling" or "inside-out signaling."
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding...

02:17The Tumor Microenvironment
6.8K
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...

03:03mTOR Signaling and Cancer Progression
3.9K
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.

02:39lncRNA - Long Non-coding RNAs
8.9K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

01:05Cancer-Critical Genes II: Tumor Suppressor Genes
7.9K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which...
