BSc (Hons), PhD
- Primary position:
- Reader in Immunogenetics
Dr Sahota was appointed as Reader in 2006. He graduated in Biochemistry and obtained his PhD in Microbial Biochemistry from the University of London, UK followed by an appointment as Lecturer and Post-doctoral Scholar in Microbial Genetics at the University of California Los Angeles, USA. Following his return to the UK, Dr Sahota engaged different research interests, and undertook cancer research at St. George’s Hospital Medical School and the Charing Cross & Westminster Hospital Medical School, University of London (examining steroid receptors in breast cancer). He was subsequently appointed in 1992 as Research Fellow / Senior Research Fellow / LRF Senior Scientist in the Cancer Sciences Division, School of Medicine, University of Southampton, before his current Faculty position.
Much of the earlier research work in Cancer Sciences, Southampton focused on developing immunogenetics to profile pathogenesis and progression in B-lymphocyte malignancy, with a special focus on multiple myeloma, a plasma cell tumour. More recent work has utilised genome wide whole exome sequencing to examine mutations to define B-cell tumour origins and behaviour, seeking to link genomic mutations with functional outcomes. Dr Sahota’s group is also interested in defining tumour-associated antigens, and in targeted immunotherapy using DNA vaccine designs. His group comprises post-doctoral scientists, visiting fellows, PhD students (non-clinical and clinical), and 4th year medical undergraduates. The group is based within the Faculty of Medicine.

Multiple myeloma – Pathogenesis, Progression and Targeted Therapy
The group has a particular focus on understanding the pathogenesis of multiple myeloma (MM), an incurable disease where malignant plasma cells accumulate in the bone marrow. One debilitating feature of the disease results from multiple osteolytic foci in the skeleton, induced by tumour growth. MM is often preceded by a proliferative condition termed monoclonal gammopathy of undetermined significance (MGUS), where a limited plasma cell expansion occurs, but it is as yet not clear what factors underlie transformation to full blown disease.
Plasma cells are terminally differentiated B-cells, but in MM, questions still remain regarding the maturation status of the cell giving rise to this tumour. We have been interested in utilizing immunoglobulin variable (V) region gene analysis to track disease evolution in B-cell tumours. V genes have also been shown to be useful, objective markers for disease classification and can predict clinical behaviour. Our group has been instrumental in defining key aspects of the pathogenesis and serial progression of MGUS to MM using this approach. On-going studies are aimed at understanding which molecular mechanisms may be contributing to malignant transformation and progression, including use of next generation sequencing to interrogate the tumour exome and genome. More recently, we were part of the European Myeloma Network specialist network ‘MSCNET’ investigating a role for a stem cell in MM evolution. Current collaborative work funded under the EU FP7 programme as part of ‘OVER-MyR’ is aimed at evaluating MM:niche cell interactions, especially in relation to mechanisms of drug resistance.
We are also interested in exploiting insights from pathogenesis of MM to inform targeted therapy, specifically by DNA vaccination. The detailed characterization on MM V genes allowed targeted DNA therapy against the tumour idiotype. Recent work has been directed at identifying antigens retained by malignant plasma cells following therapy, to allow effective vaccination against MM cells on relapse. We have focused on cancer testis antigens (CTAs) in this regard. Vaccines generated against newly identified CTAs in MM are also currently being evaluated using pre-clinical transgenic models.
There is a parallel interest in probing developmental events in the origins and behaviour of other B-cell tumours, in particular Hairy Cell Leukaemia (HCL) and Waldenstrom’s macroglobulinemia (WM). Here, our investigations include analysis of early and late maturation events, as revealed by analysis of somatic mutation imprints in Ig and non-Ig loci, especially the 5’ non-coding region of the BCL-6 gene, a proto-oncogene encoding a transcriptional repressor. In addition, we are evaluating the role of the B-cell receptor and niche interactions in HCL and WM persistence. In these B-cell tumours, notable observations have been established by PhD rotation project students and undergraduate medical students.
Individuals interested in joining any aspect of this research work are encouraged to contact the group informally. The group usually has one or two places for medical students undertaking a study in depth by research as part of the BMed / MMed Sci degrees.
