Dr Sushila Rigas
Lecturer in Health Sciences
I have worked on research projects characterising DNA variants in cancers and I now run a research group focused on identifying functional and regulatory DNA and RNA variants that may affect risk of breast cancer and other cancers with putative shared aetiology. We collaborate with Dr Francesco Crea's group within the Open University, identifying lnRNA variants putatively underlying risk of prostate and other cancers. I also collaborate with Professor Angela Cox (University of Sheffield) on the Identification of regulatory DNA variants in apoptosis genes associated with breast cancer risk (Yorkshire Cancer Research) and Professor Nicola J Camp (University of Utah, USA). My first post-doctoral position was in Professor Angela Cox's group where we were the first to identify that the Caspase 8 gene (Casp8) was associated with risk of breast cancer and subsequently identify CASP8 and other apoptosis DNA variants (Yorkshire Cancer Research, Cancer Research UK, Breast Cancer Campaign, and the Wellcome Trust). Whilst doing my PhD (The role of p14ARF in familial and sporadic melanoma, funded by Imperial Cancer Research now called Cancer Research UK) in Professor D Timothy Bishop and Professor Julia Newton-Bishops's group with Professor Margaret A Knowles (University of Leeds) I was the first to: comprehensively screen for deletions on chromosome 9p in melanoma families and in sporadic melanomas (at a time when it was difficult for detect deletions and loss of heterozygosity, LOH); to identify p14ARF [CDKN2A-ARF gene (exon 1β)] as a tumour suppressor gene; identify the MTAP to KIAA1 gene region as important in melanoma aetiology and a candidate locus for the location of a tumour suppressor gene; and contributed to being the first to identify that introns are important in disease with the detection of a splicing variant (IVS2-105) in melanoma families.
Tools: genetic (e.g. high throughput PCR, allelic discrimination, sequencing, MLPA, qPCR), molecular (e.g. cell culture, flow cytometry), and data mining using publically available online databases e.g. dbSNP, Ensembl, UCSC, GEO etc. Mainly gene expression tools.
Key words: cancer, breast cancer, genetics, molecular science, epidemiology, bioinformatics, data mining, DNA variants, RNA variants, DNA characterisation, RNA expression, protein expression.

Title: Identification of functional variants in breast and other cancers with putative shared aetiology.
Funding: The Open University
Supervisors: Dr Sushila Rigas, Dr Mark Hirst, Dr Francesco Crea, Professor Angela Cox (University of Sheffield)
Overview:
The role or function of DNA and RNA variants associated with cancers, as identified in genome wide association studies (GWAS) and candidate gene approaches, are largely unknown. There is evidence that they may be involved in the regulation of gene expression e.g. as expression quantitative trait locus (eQTL) or splicing quantitative trait locus (sQTL) variants, or involved in certain cellular pathways such as: apoptosis, signal transduction, angiogenesis, cell motility, communication and development, DNA repair and replication, metabolism, and endocrine or nervous system development. There are also multiple genes that are associated with breast, ovarian and prostate cancers which suggests there may be a shared aetiology. Most of the low-penetrance genes that are underlying these 'shared' cancers are largely unknown. This project aims to identify the candidate functional variants, and their putative role across 'shared cancers'.

Impact and engagement
In collaboration with Professor Angela Cox (Breast Cancer Consortium, UK) we are currently aiming to work towards developing personalised screening tools (blood tests) and therapies, including identifying novel target therapies; by characterising DNA and RNA variants and identifying novel putative variants that are functional in the risk of breast cancer and other cancers with shared aetiology.
