Summary
Integrin αvβ3, a hormone receptor, collaborates with estrogen receptors (ER-α) and GPER in non-genomic pathways, influencing cancer growth and metastasis. This interaction highlights integrin αvβ3 as a potential therapeutic target for hormone-driven cancers.
Area of Science:
- Molecular Biology
- Cell Biology
- Oncology
Background:
- Integrin αvβ3 is crucial for cell functions and uniquely expressed in cancer cells, suggesting a role in tumor progression.
- Estrogen signaling occurs through genomic and non-genomic pathways, with non-genomic actions involving G protein-coupled estrogen receptor 1 (GPER).
Purpose of the Study:
- To investigate the non-genomic roles of Integrin αvβ3 in collaboration with estrogen receptors (ER-α) and GPER in cancer biology.
- To elucidate the molecular mechanisms underlying these non-genomic functions.
Main Methods:
- Analysis of signal transduction pathways including focal activated kinase (FAK), mitogen-activated protein kinase (ERK1/2), and phosphatidylinositol 3-kinase (PI3K).
- Examination of differential gene expression related to cellular processes in cancer.
Main Results:
- Integrin αvβ3, ER-α, and GPER cooperate in non-genomic signaling pathways that promote estrogen-induced cancer growth.
- These interactions involve key signal transduction molecules (FAK, ERK1/2, PI3K) and affect multiple cancer-related genes.
Conclusions:
- Integrin αvβ3 acts as a hormone receptor, mediating non-genomic estrogen effects crucial for cancer progression.
- The interplay between Integrin αvβ3, ER-α, and GPER presents a novel therapeutic strategy for targeting hormone-dependent cancers.

01:17Intracellular Signaling Affects Focal Adhesions
3.4K
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.

01:15Activation of Integrins
4.9K
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...

Animal and protozoan cells do not have cell walls to help maintain shape and provide structural stability. Instead, these eukaryotic cells secrete a sticky mass of carbohydrates and proteins into the spaces between adjacent cells. This network of proteins and molecules is called an extracellular matrix or ECM.
Some ECM proteins assemble into a basement membrane to which the remaining components adhere. Proteoglycans typically form the bulk of the ECM while fibrous proteins, like collagen,...

01:15Receptor Downregulation in MVBs
2.7K
Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that lead to cell proliferation, migration, and differentiation. Overexpression of EGFR stimulates cells to proliferate. Excessive EGFR...

10.4K
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...

01:45Endocrine Signaling
67.7K
Endocrine cells produce hormones to communicate with remote target cells found in other organs. The hormone reaches these distant areas using the circulatory system. This exposes the whole organism to the hormone but only those cells expressing hormone receptors or target cells are affected. Thus, endocrine signaling induces slow responses from its target cells but these effects also last longer.
