Target Discovery
Target discovery and functional validation using human in vitro models
Led by Dr Erica Bello, the Target Discovery Group focuses on enabling functional genomic screenings in complex human in vitro models of disease to identify clinically relevant, high-confidence targets for disease therapy.
This team collaborates with academic researchers and clinicians in Cambridge and beyond who have expertise in specific disease areas (e.g. inflammatory bowel disease) and have developed physiologically relevant in vitro models. Their aim is to develop, adapt, and optimise gene editing protocols, high-throughput culture methods and endpoint assays in these complex models, to enable functional genomics screening workflows. These workflows are used to elucidate disease mechanisms and identify novel therapeutic targets.
The Target Discovery Group works with arrayed and pooled CRISPR screening methods and various target validation approaches. They provide important input into the Functional Genomics Screening Laboratory through their expertise in the development and scaling of complex models. The Target Discovery Group also collaborates with the AI and Computational Research Group in the generation and biological interpretation of CRISPR screening and multi-omics datasets. More recently, the Target Discovery Group has contributed to training future scientists through the School of Biological Sciences MPhil programme.

CRUK CAMBRIDGE CENTRE
The Milner Therapeutics Institute (MTI) is a physical affiliated research institute of the Cancer Research UK Cambridge Centre.
The MTI has three goals to help drive the development of new medicines:
- To facilitate collaborations between academic researchers and those based in the pharmaceutical industry.
- To carry out our own research focused on finding new treatments through partnership with clinicians and scientists throughout the UK.
- To enable the next generation of scientific entrepreneurs to develop new companies to deliver new treatments for disease.
These goals are aligned with the Cambridge Centre’s strategies of conducting impactful research, enabling early diagnosis, developing new leaders in cancer research and partnering with patients and the public. Through the Milner Therapeutics Consortium, we help to build teams of researchers to work together to solve challenges in cancer research. Our research teams use computational approaches and artificial intelligence to analyse information from patient samples. These data can reveal new targets to treat cancer or drug combinations that could reduce the chance of drug resistance occurring.
