Role of G protein-coupled receptor kinases (GRKs) in CXCR4 and CXCR7 signalling and modulation

Early stage researcher 8 (ESR8) project – Maria Martins Neves
Supervision: Prof F Mayor, Dr P Penela, Dr C Murga
Host: UAM (ES) – Universidad Autónoma de Madrid, Department of Molecular Biology, Center for Molecular Biology “Severo Ochoa”

I- Project proposal:

Aim:
1. Identify the GRK subtypes engaged by CXCR4/CXCR7 modulators in healthy and cancer cells.

2. Analyse the effect of altered GRK subtype levels on CXCR4 and CXCR7-mediated signalling and in vivo angiogenesis and cancer progression.

Methodology:
Cell signalling techniques, Co-ip and confocal microscopy in cell models with different GRK dosage, 2D and 3D migration/invasion assays, XCell-based adhesion and proliferation assays, in vivo angiogenesis and xenografts in already available mice models (GRK2 hemizygous, endothelial-specific GRK2 KO, inducible GRK2 KO).

Planned secondments: UWUE (DE), VU (NL).

 

II- Requirement candidate:

Required diploma: MSc degree in molecular/biomedical Life Sciences, Pharmaceutical Sciences or related Life Sciences degree.

Required expertise: cell culture, cell-based assays, biochemistry, molecular biology. Recommended expertise: GPCR signalling, confocal microscopy, migration and proliferation assays, in vivo murine cancer models

The transatlantic ECI GPCR symposium #ECIGPCR is about to start, we are ready!! Thanks to the organizers for their excellent job gathering almost 500 people across the globe! @cyclic_Andreas @NicoleAPerry1 @BenderSci @DesislavaNeshe1

My project will be focused on the role of #CXCR4/ACKR3/GRK2 -governed networks in cancer cell migration and metastasis.

Hello 🙂
I am here to continue the series in which all #ESRs are presenting themselves. I am Viviana Marolda and I am in my first year of PhD. I am #ESR13, originally from Italy, and currently, I am working as a PhD student in @CBMSO_CSIC_UAM, at Universidad Autonoma de Madrid.

Hey twitter!
I am @DehanComez. I am taking over the Oncornet account for a while to start a series of all #ESRs writing about themselves and their projects. I am #ESR5, originally from Turkey and right now I am working as a PhD student in @COMPARE_UoBUoN , @UniofNottingham , UK.

New review on #gpcr structural dynamics out in COSB. Great teamwork with the @JanaSelent group. Thanks to @Lundbeckfonden and @novonordiskfond https://lnkd.in/eyjrA5V

ONCORNET2.0 is the successor to #ONCORNET. You can see some of the work of ESRs from the first ONCORNET in this special issue of @MolPharmJournal from 2019, with reviews on #CXCR4 and #ACKR3 structure and function: https://molpharm.aspetjournals.org/content/96/6

Hi everyone – we’re on Twitter! ONCORNET2.0 is a #MarieCurie ITN of 16 ESRs across Europe studying #chemokine #GPCRs #CXCR4 and #ACKR3 in cancer. Our projects cover molecular dynamics, medchem, #pharmacology through to translational work. Follow us for updates from our ESRs!

Hi everyone!

Public service announcement: our Marie-Curie ITN @ONCORNET1 is on Twitter! The 16 wonderful #ECRs working on the project will soon be Tweeting about #GPCR #chemokine #ECR life and #pharmacology

Please #RT & consider a follow or follow back! 🙏😀
