Karen Vousden: Getting the big picture on p53
نویسنده
چکیده
p 53 is famous—or infamous—as a fulcrum in the development of cancer. As a transcription factor, it controls the expression of a bevy of genes that protect cells in times of stress or, when stresses exceed certain thresholds, sends them down the path to cellular suicide. Its mutation or loss is observed in many types of cancer. Karen Vousden has been studying p53 since the early stages of her career as an independent scientist. Her lab has investigated everything from the processes that regulate p53 stability (1, 2) to the genes whose expression is controlled by p53 (3, 4) and the functions of mutant versions of p53 that accumulate in cancer cells (5). We called her at her lab at Cancer Research UK's Beatson Institute in Glasgow, where she's now the Director, to fl esh out the details on p53 and to sketch the larger picture of her career. Where did you grow up? I grew up in Gravesend, an industrial town on the banks of the Thames in the southeast of England. Neither of my parents is an academic; my mother was a school dinner lady, and my father was a toolmaker in a factory. They always strongly supported me in my schoolwork but never really had any academic aspirations for me. Nonetheless, they are very happy about the way things worked out. When I was little, I wanted to be a teacher. Then, when I went to secondary school, I had some outstanding chemistry and biology teachers who encouraged an ambition to become a scientist. But when I was about 14, a career advisor visited the school. She asked me what I wanted to do, so I said, " I want to be a research scientist , " and she said, " Oh, that's much too diffi cult. Have you thought about working in a bank? " [Laughs] So in spite of this advice— Yeah, I stuck with it. In the end, I went to the University of London and studied biology. I started off in straight biology courses and then ended up graduating with a degree in microbiology and genetics. But I never really had a long-term plan. Now I occasionally get invited to talk to graduate students, and they want insights into the right steps and strategy for a career in science. But I always feel I have nothing to offer because I had no strategy—I …

Functions of p53 in metabolism and invasion.
The p53 protein is an important tumour suppressor that is inactivated in many human cancers. Understanding how p53 is regulated and the downstream consequences of p53 function is helping us to devise novel therapies based on the reactivation of p53. Such approaches may be useful in the treatment of cancer, but a growing understanding of a role for p53 in other conditions suggests that modulatio...
متن کاملP53 and Prognosis New Insights and Further Complexity
Despite the massive amount of knowledge that has accumulated about p53, there is still much to learn about its role in tumor suppression. New papers now provide evidence that levels of Mdm2 in humans or presence of mutant forms of p53 in mice can have profound impacts on survival and tumorigenesis. These findings may lead to new diagnostic and therapeutic approaches to treating cancer patients.
متن کاملp53, ROS and senescence in the control of aging
In addition to its function as a tumour suppressor, p53 is also involved in an increasing number of pathology associated with aging. Several activities of p53 appear contribute to its role in aging; one function that might be particularly relevant in this context is the regulation of senescence. The control of ROS and senescence by p53 may help to explain how p53 can function to both restrain a...
متن کاملMutant p53 in Cancer: New Functions and Therapeutic Opportunities
Many different types of cancer show a high incidence of TP53 mutations, leading to the expression of mutant p53 proteins. There is growing evidence that these mutant p53s have both lost wild-type p53 tumor suppressor activity and gained functions that help to contribute to malignant progression. Understanding the functions of mutant p53 will help in the development of new therapeutic approaches...
