Signal Transduction in Cancer Biology

Gough group

One in 20 people will be diagnosed with lung cancer by the age of 85. The Signal Transduction in Cancer Biology group is guiding new treatment approaches by defining how disruption to immune signalling pathways, through the critical STAT family of proteins, alters the onset and progression of lung cancer tumours.

There are several reasons why lung cancer is the deadliest cancer, including late detection, early and widespread metastasis, and poor response rates to current treatments including chemotherapy and recently approved immune based therapies.

The interaction between a tumour, its surrounding tissue and the immune system is a critical aspect of response to lung cancer treatment and metastatic potential.  The Signal Transduction in Cancer Biology group investigates the tumour-immune ecosystem, with the goal of identifying how its interactions could be manipulated to find new therapeutic approaches.

The team are building this knowledge through research into fundamental cell communication networks, and how these are altered in cancer. These findings are translated into sophisticated cancer models and patient tissue, enabling a detailed understanding. The overarching goal is to use this knowledge to design better therapeutic approaches for lung cancer patients.

The Gough group’s expertise is in Signal Transducer and Activator of Transcription 3 (STAT3) proteins which are overexpressed lung cancer and promote tumour growth. They focus on the signal transduction pathways that engage STAT3 proteins in normal development, and how these pathways are altered in lung cancer.

STAT3 is a critical signalling protein that is essential for life. When activated, STAT3 initiates hundreds of genes necessary for proliferation, immune function, apoptosis, metabolism, and differentiation. STAT3 activity is tightly controlled. Too little activation results in immune disorders, while overaction is observed in more than 50 per cent of tumours with a poor prognosis. It is now emerging that in some tumour types, STAT3 acts as a tumour suppressor, but this has not yet been explained.
