The PRH/HHEX protein is a transcription factor that functions as a tumour suppressor protein in some types of cancer, including breast cancer and prostate cancer (Gaston et al, 2016: Kershaw, et al 2017). However, this protein functions as an oncoprotein in other cancer types, such as bile duct cancer (Kitchen et al, 2019). The PRH/HHEX gene is therefore a proto-oncogene with tumour-suppressor function (Shen et al., 2018). Less than 100 such dual action oncoprotein/tumour suppressor proteins have been identified to date and we need to know more about these proteins are involved in tumourigenesis.
The aim of this project is to determine how the PRH/HHEX protein can function in such different ways depending on the cell type in which it is expressed and its expression level. In this project we will:
(1) Measure PRH/HHEX protein levels in cancer tissues using immunohistochemistry.
(2) Compare the genes that are regulated by PRH/HHEX in different cell types using RNA sequencing and chromatin immunoprecipitation sequencing.
(3) Identify PRH/HHEX interacting proteins in different tissues using proteomics.
These experiments will increase our understanding of the role of PRH/HHEX in cancer and this could result in new approaches to cancer treatment.
