PhD Position / Promotionsstelle

The Institute of Physiology and Pathophysiology of Heidelberg University, Department of Cardiovascular Physiology (Prof. Dr. Markus Hecker) offers a
  PhD position
Project Title: Impact of the transcription factor NFAT5 on vascular responses in the hypoxic lung

Application deadline: 13 January 2019

Start of PhD project: 01 March 2019

Activities and responsibilities

Project description:
The lung forms a specialized border for gas exchange and may rapidly respond to local hypoxia by adapting its perfusion for optimized blood oxygenation. However, chronic hypoxia that is associated with many pulmonary diseases (e.g. fibrosis or chronic obstructive pulmonary disease, COPD) promotes irreversible structural remodeling and subsequent lung dysfunction. We observed that the transcription factor NFAT5 is expressed in vascular endothelial and smooth muscle cells of the hypoxic lung and seek to study its role in controlling structural remodeling and inflammatory responses. Specifically, the NFAT5-dependent modification of the vascular transcriptome and its impact on pulmonary resistance, blood oxygenation and activation of alveolar macrophages will be investigated.

Our work group (AG Korff) grants a professional and individual supervision of PhD students and provides a stimulating atmosphere within a team of young and enthusiastic scientists. The work program of this project allows applying a wide range of cutting-edge techniques which guarantees a high level of scientific training. We also offer in-house methods seminars for advanced training and support participation on international meetings. Detailed information about our group can be obtained from the institute’s website

Methods that will be used:
The experimental portfolio of this project includes already established multiple state-of-the-art in vitro and in vivo techniques. For instance, adenovirus-based transduction will be used to overexpress/knockout NFAT5 in cultured hypoxia-exposed endothelial and smooth muscle cells. Mouse lines allowing for cell specific inducible knockout of NFAT5 are available to study the impact of NFAT5 on lung functions in the context of hypoxia. Morphological studies will be performed based on whole mount immunofluorescence analyses in combination with confocal microscopy. To unravel the mechanisms by which NFAT5 controls cellular functions microarray and proteome profiling techniques will be applied.

Qualification profile

Successful candidates should enjoy competitive and interactive teamwork within the new CRC1366 “Vascular Control of Organ Function” and the European Center for AngioScience (ECAS). They should have great interest in the life sciences, modern cell and molecular biology methods as well as physiology. Experience with animal handling (FELASA B certificate or equivalent) would be beneficial but is not mandatory for application. The PhD student should also be willing to participate in local Integrated Research Training Groups which will provide young researchers with scientific competence as well as laboratory management and communication skills.

Wir stehen für Chancengleichheit. Schwerbehinderte werden bei gleicher Eignung vorrangig eingestellt. Das Universitätsklinikum strebt eine generelle Erhöhung des Frauenanteils in allen Bereichen und Positionen an, in denen Frauen unterrepräsentiert sind. Qualifizierte Frauen sind daher besonders aufgefordert, sich zu bewerben. Vollzeitstellen sind grundsätzlich teilbar, soweit dienstliche oder rechtliche Gründe nicht entgegenstehen.
