Fran Balkwill
Fran Balkwill is head of cancer and inflammation at the Institute of Cancer at Barts and The London School of Medicine and Dentistry
When Fran Balkwill needed material for her PhD experiments on leukaemia in 1973, she simply went down to the ward to bleed the patients. Though she doubts sheâd be allowed to do that today, it was this early contact with patients that was instrumental in cementing her career choice. âThe immediacy of actually dealing with patients was very important to me,â she says. âIt made me want to do something closely related to cancer treatment.â
Today she does just that. Jointly funded by Barts and Cancer Research UK, Balkwill is investigating the link between cancer and inflammation, translating ideas from the lab into clinical trials.

âSome people think of cancer as just a ball of genetically altered cells growing out of control,â says Balkwill, âbut itâs not â itâs a rogue organ.â Alongside the malignant cells, she explains, cancers are more often than not made up of a whole host of other components, including inflammatory cells and mediators.
This micro-environment around cancer cells is a crucial factor in allowing cancer to spread. âThe inflammatory cells you find in the cancer are more likely to be there to support it, to help it grow, rather than as a host response to beat it,â she says. Through targeting supporting cells along with the malignant ones, novel therapies could emerge and existing treatments greatly improved.
Balkwillâs career path has taken her through some unusual and sometimes tragic events, most notably the death of her PhD supervisor Gordon Hamilton-Fairley, one of the worldâs leading oncologists, in an IRA bombing. âIt was a very strange time,â she says, âand I was on my own quite a bit.â But the experience forced her to learn how to work independently â a skill that has proven useful throughout her career.
Balkwill had originally been set to go to medical school, but felt uncertain about this career choice. Fortuitously, this coincided with the inception of a new course in cellular pathology at the University of Bristol. Established by the distinguished pathologist Tony Epstein, the course focused on practical work and set Balkwill on the path to research.
Epsteinâs ability to tell stories would also be influential. âHe really conveyed the excitement and the serendipity of science,â Balkwill recalls. Indeed, telling stories about science is something Balkwill does rather well herself. âI had two young children and I wanted to explain to them what I did during the day,â she says. âI thought there must be fabulous picture books on cells, and I was completely flabbergasted that there werenât.â Since then she has written over a dozen popular science books for children.
Balkwillâs talent for communicating science was this year rewarded with an OBE, not just for her books but also for her role as director of Centre of the Cell at Barts. An exciting new interactive science centre for children, itâs âprobably the only one in the world housed right in the centre of a research buildingâ, she says.
Getting to where she is today has not come easily, and it can be all too easy to give up on a career in science when times get tough, says Balkwill. So itâs a question of being persistent, then reaping the rewards. âScience can be extremely frustrating,â she says, âbut itâs never boringâ.

X-men arenât just fictional mutant superheroes. Ask Chris Torrance, head of Horizon Discovery. To him, âX-MANâ means âGene X â Mutant and Normalâ, which is the name of his companyâs product â a range of mutant cell lines with potentially lifesaving powers.
Horizon Discovery is a young business that provides cancer researchers working in personalised medicine with pairs of cell lines that are genetically identical, or isogenic. The only difference between the two lines, Torrance explains, will be a specified gene â call it gene X. One line has a normal copy and the other a mutant version, which causes a disease. âBecause they are otherwise isogenic, we have a definitive view on how this mutant gene causes the disease, and a tool to find novel drugs that selectively kill it,â he explains. This is important information in the field of personalised medicine, he says, âwhere the idea is to get the right drug in the right patient, based on the genetics of their specific cancerâ.
ÂThe idea is to get the right drug, based on the genetics of the cancerÂ
Horizon Discovery is exciting because commercialising these cell lines has never before been possible in human cells. âIn the past itâs been very hard to get patient-predictive cancer models in the laboratory,â says Torrance. Thatâs because getting the mutations to truly resemble those you see in the body requires a very specific gene-engineering technology.
This is the technology that Torranceâs company is built around. âWe are the first and only company that can actually take a human cell line grown in a laboratory and genetically engineer it to create very specific disease models.â
Torrance believes it was a year spent in industry, during his undergraduate degree at what is now Sheffield Hallam University, that whetted his appetite for drug discovery. After he completed a PhD in diabetes, his growing interest in cancer lead him to Johns Hopkins University in Baltimore, Maryland, where he spent six years learning the techniques of human cell engineering and their uses in drug discovery.
To successfully target pharmaceutical companies with his idea, Torrance felt he needed more time in industry. So he went to work for biotech firm Vernalis for five years, gaining insider experience, before following his dream and finally going solo.
âCancer is not caused by one gene that goes wrong, itâs generally three or four,â says Torrance, which is why he is now looking towards X-MAN2 â using combinations of targeted drugs for a patient-specific, multi-faceted attack on cancers.
Though it was just over a year ago that Torrance left Vernalis to start Horizon Discovery, his new company already is doing well. Branching out on your own involves an element of risk, but so far his investment has paid off. âI love doing science and trying to make a difference doing science,â he says, âand I can do that more than ever by running my own company.â
Ruth Plummer
Ruth Plummer is a clinical professor of experimental cancer medicine at the Northern Institute for Cancer Research (NICR), Newcastle University
In Ruth Plummerâs line of work, it pays to tread carefully. âYou donât take anything into the clinic that doesnât look as though itâs got promise,â she says, âbut you donât know anything for certain, so you canât be too optimistic with people.â
At the NICR, Plummer spends much of her time working on early-stage clinical trials. Her caution is justified. Unlike in the well-publicised TeGenero incident, in which six healthy young volunteers in a phase I drugs trial were left fighting for their lives, Plummerâs patients are already extremely ill. Suffering from incurable cancers, they have tried all available treatments before looking to the clinic for hope. So although these trials seek primarily to establish dose and side effects, âthe best possible outcome of a phase I trial for a patient is that they get clinical benefit, that the treatment shrinks their disease or stabilises it so that they feel well and can get on with having a good quality of lifeâ, says Plummer.
Having studied at both the universities of Cambridge and Oxford, Plummer returned to her home town to finish her professional qualifications in cancer drug development at Newcastle University. She has now worked at the university for 13 years and knows many of her patients extremely well. Sadly, some donât last long in the trials but others visit each week for years â something Plummer never quite gets used to: âThere are always patients who catch you out, ones you get more fond of.â The bigger picture, however, is encouraging. âThe best outcome is that we help move forward the development of a useful anti-cancer drug, helping lots of patients,â she says.
Alongside the trials, Plummer practises as a clinical oncologist, helping patients battle melanoma and sarcoma. She also supervises students and handles the administrative side of her research.
With three degrees and boundless energy, Plummer is certainly inspirational. Yet not all jobs in cancer trials require this level of expertise. Indeed, some donât require a degree at all. For the role of data manager, for example, skill in handling data and a good grasp of the clinical trial process is more important than a degree. Then there are research nurses â oncology nurses who have undergone additional training. They are instrumental in the preparation of trials and the design of studies, says Plummer.
Working with terminally ill patients can be a challenge, Plummer admits, but it isnât a bleak one. âThe patients are absolutely fantastic. These are people who know they are dying and say, âIâd like to try this, Iâd like you to offer me some hope, and Iâd like to feel I tried to do something to help,â so itâs a really positive unit to work in.â
