爱尔兰皇家外科医学院招收癌症生物学博士后

2012-09-13 11:45 来源: 未知 作者: admin

Objective:The available post is for a Postdoctoral Position to support the investigator’s research programme in Cancer Biology and Apoptosis

Reporting to:Prof Jochen Prehn (Principal Investigator)

Project background and description:The Centre for Systems Medicine and the Department of Physiology and Medical Physics investigate apoptosis signalling pathways and stress pathways and their role as prognostic markers and novel targets for the treatment of cancer. It is funded by Science Foundation Ireland, the European Union, as well as the Irish Health Research Board.

In a study funded by the Health Research Board (APO-COLON), we identified the proteasomal subunit Rpt4 to be elevated in colorectal cancer tissue when compared to matched normal tissue. Furthermore,in vitroas well asin vivoxenograft studies using gene silencing approaches suggested that inhibition of Rpt4 function is an attractive new target for the treatment of cancer.

The project aims to further evaluate the future potential of targeting Rpt4 expression as therapies for cancer. Studies include: A) Analysis of Rpt4 expression in tumour samples to examine whether any acute changes can be observed in Rpt4 expression following neoadjuvant radiochemotherapy or during metastatic progression. B)In vitrocharacterization experiments investigating the specificity of Rpt4 inhibition towards cancer cell survival. C) Identifying small molecule inhibitors of Rpt4, including the development of high-throughput assays.

Further duties of this post will include:
• Complying with statutory legislation and Department rules and requirements in furtherance of your own and general staff welfare and safety
• Undergoing programmes of training and development as may be required from time to time
• Representing the best interests of the Department/RCSIat all times
• Performing such other duties as may be required from time to time.

Availability:The position will be available from October 1st.

Person Specification:The candidate should have a PhD in Biochemistry, Pharmacology or Cell Biology, ideally in the field of cancer biology, apoptosis, or proteasomal function. (S)he should have significant research experience in the subject areas described as documented by publications. (S)he needs to be able to independently plan and conduct the research project and to integrate into a interdisciplinary research environment. Grant writing skills and experience in the supervision of undergraduate students in research is of advantage.

Salary:The successful candidate will be appointed on the salary scale for postdocotrates at a point commensurate with qualifications and experience.

Application procedure:Please send a CV and names of at least two referees plus accompanying documentation (such as certificates, publications) tojprehn@rcsi.ie

Closing date:Applications must be received by Friday 21st of September, 2012.
