The Itgb3 Adhesome - Integrin β3 is seen as a key anti-angiogenic target for cancer treatment due to its expression on neovasculature

ABSTRACT: Integrin β3 is seen as a key anti-angiogenic target for cancer treatment due to its expression on neovasculature, but the role it plays in the process is complex; whether it is pro- or anti-angiogenic depends on the context in which it is expressed. To understand precisely β3’s role in regulating integrin adhesion complexes in endothelial cells, we characterised, by mass spectrometry, the β3-dependent adhesome. We show that depletion of β3-integrin in this cell type leads to changes in microtubule behaviour that control their migration. β3-integrin regulates microtubule stability in endothelial cells through Rcc2/Anxa2 driven control of active Rac1 localisation. Our findings reveal that angiogenic processes, both in vitro and in vivo, are more sensitive to microtubule targeting agents when β3-integrin levels are reduced.

RNAseq analysis of integrin β3-mediated responses to in vitro docetaxel in PyMT-BO1 breast cancer cells

Project description:We sought to transcriptomically characterize the effect of integrin β3 expression on breast cancer cell responses to the microtubule-inhibiting chemotherapeutic agent docetaxel. Experiments were performed in PyMT-BO1 murine breast cancer cells with CRISPR mediated deletion of the Itgb3 gene. Cells were subsequently retrovirally rescued using either an empty vector construct (pMx), a functional human integrin β3 construct (hβ3), or a signaling-deficient integrin β3 mutant.

Proteomic analysis of integrin adhesion complex disassembly induced by nocodazole

Project description:To explore the dynamics of integrin adhesion complex disassembly, isolated adhesion complexes from U2OS cells were subjected to mass spectrometry based proteomic analysis. U2OS cells were allowed to spread on FN, treated with nocodazole for 4 hours to disrupt microtubules. To coordinate microtubule-induced integrin adhesion complex disassembly nocodazole was subsequently washed out and adhesion complexes isolated at 5, 10 and 15 minutes during this process.

sVEGFR-1 signaling through Î±5Î²1 integrin

Project description:Soluble VEGFR-1 (sVEGFR-1) acts both as a decoy receptor for VEGFs and as an extracellular matrix protein for Î±5Î²1 integrin. A sVEGFR-1-derived peptide that interacts with Î±5Î²1 integrin promotes angiogenesis. However, canonical signal downstream integrin activation is not induced, resulting into lack of focal adhesion maturation. We performed a gene expression profile of endothelial cells adhering on sVEGFR-1 compared to that of cells adhering on fibronectin, the principal Î±5Î²1 integrin ligand. Three protein kinase-C substrates, adducin, MARCKS, and radixin were differently modulated. Adducin and MARCKS were less phosphorylated whereas radixin was higher phosphorylated in sVEGFR-1 adhering cells, the latter leading to prolonged small GTPase Rac1 activation and induction of a pathway involving the heterotrimeric G protein Î±13. Altogether, our data indicated endothelial cell acquisition of an highly motile phenotype when adherent on sVEGFR-1. Finally, we indicated radixin as accountable for the angiogenic effect of Î±5Î²1 integrin interaction with sVEGFR-1 that in turn depends on an active VEGF-A/VEGFR-2 signaling. Endothelial cells were let adhere in Petri dishes coated with fibronectin or sVEGFR-1 before RNA extraction and hybridization on Affymetrix microarrays. Endothelial cells plated on BSA-treated Petri dishes were used as non-adhesion control. Each hybridization was performed in triplicate.

Gene expressions in pancreatic cancer cells

Project description:We used time-dependent spheroidal cultures of pancreatic cancer cells to investigate how spatiotemporal regulation in spheroids induces epithelial-mesenchymal plasticity (EMP). We generated a round bottom spheroidal model using β3 integrin-negative pancreatic cancer cells in 2D conventional monolayer cultures, and compared the expression of integrin signaling-related genes that induce spheroidal geometry to determine if spheroidal geometry induces integrin switching.

Integrin beta 3 regulates cellular senescence by activating the TGFβ pathway

Project description:Cellular senescence is an important in vivo mechanism that prevents the propagation of damaged cells. However, the precise mechanism(s) regulating senescence are not well characterized. Here, we find that ITGB3 (integrin beta 3 or β3) is epigenetically regulated by the Polycomb protein CBX7. β3 expression accelerates the onset of senescence in human primary fibroblasts, by activating the TGFβ pathway in a cell autonomous and non-cell autonomous manner. β3 levels are dynamically increased during oncogeneinduced senescence (OIS) through CBX7 epigenetic regulation. DNA-damage and therapy-induced senescence (TIS) also induce β3 expression. In fact, downregulation of β3 levels override OIS and TIS, independently of its ligand-binding activity. Moreover, cilengitide, a αvβ3 antagonist, has the ability to block the SASP without affecting proliferation. Finally, we show an increase in β3 levels during aging in mice and humans. Altogether, our data show that integrin β3 subunit is a marker and regulator of senescence.
