Postdoc (3 yr) Intracellular Notch trafficking and stem cell fate

Maastricht University

Netherlands

November 11, 2021

Description

Job description

Background: Notch proteins are master regulators of cell fate during development and control cell renewal and differentiation in most adult tissues. Activation of Notch proteins is regulated by successive enzymatic cleavages that release the cell membrane-bound form that acts as a transcriptional regulator. More recently, import roles of intracellular vesicles in regulating Notch activity are being identified (see Pubmed 34572582). We have now identified metal-binding transporters (DMT1) as key mediators of intracellular Notch trafficking and activity.

Key objectives. To identify the importance of metal transport on intracellular Notch localization and activity in vesicles and how this can block Notch activity in tumours or promote regeneration of normal cell types. You will apply gain and loss of function (CRISPR, siRNA pharmacological) in Notch-dependent 2D and 3D models (cell lines, normal and tumour organoids (lung, intestine) and high-resolution fluorescent imaging (confocal, STED) and single-cell analysis to decipher how Dmt1/Notch signaling allocates cell identify and how iron transport is involved. You will use reagents we developed (Ab's, Tg mouse models) to track the fate of Notch activity in fixed and live tissues.

Requirements

We are looking for a Postdoc with a PhD in molecular and cell biology and a broad experience and track record with primary cell culture and cellular imaging using confocal fluorescence microscopy. You will be working in a team with a strong expertise in Notch biology.

General Profile: We are looking for an open-minded, independent and result-oriented scientist to join our team with a strong interested in fundamental research into regenerative medicine. You are fluent in English, both in writing and speech.

Department GROW Institute for Oncology and Developmental Biology

Maastricht University, GROW Institute for Oncology and Developmental Biology (www. grow-um.nl) . The radiotherapy department (www. maastrolab.com) conducts fundamental and translational research and is closely affiliated with Maastro patient clinic and the Maastricht Comprehensive Cancer Centre. Our research is focused on identifying therapeutic vulnerabilities in the tumour microenvironment to improve treatment response. The lab has four PI's with research in the area of tumour cell metabolism (Kampen Group), Cell death (Bock group), Extracellular vesicles (Rouschop group) and Notch and Stem cells (Vooijs Group). In addition, we have established a strong expertise in culturing normal, and tumour stem cell models (organoids. ALI) and have access to a large tissue biobank and material from clinical studies. We have excellent high resoltuion optical microscopy and regenerative medicine.
