The MAP kinase pathways play important roles in normal cellular function and are often disrupted in diseases such as cancer. One major route through which these pathways function is through changing the activities of transcription factors. However, the simplistic model that MAP kinase signaling takes a linear route from the cell membrane to the nucleus and through a limited number of transcription factors to control gene expression programmes, is clearly a vast over-simplification. Recently, in an attempt to expand this regulatory network we performed two genome-wide RNAi screens to identify novel regulators of MAP kinase pathway signalling that impact on gene expression programmes. Several novel regulators were identified. The aim of this project is to discover the role of these novel regulators in controlling the transcriptional output of the MAP kinase signalling pathways by using systems based approaches. Novel methodologies based around Next generation sequencing will be employed and the biological role of the findings will be determined in the context of embryonic stem cell differentiation and under conditions of highly active ERK signalling in cancer such as in oesophageal adenocarcinoma.
