Cleo Bishop, BSc PhD

Profile

Cleo received her PhD in Biological Sciences from University College London in 2001. She then spent four years as a MRC Career Development Fellow in the laboratory of Prof. Chris Higgins at the MRC Clinical Sciences Centre (now the London Institute of Medical Sciences), Imperial College London, where she developed a keen interest in cancer biology.

In 2006, she moved to the Blizard Institute to pursue her interest in senescence and cancer, spending four years in the laboratory of Prof. David Beach (FRS). During this time, she established our Phenotypic Screening facility, and has used this technology to discover novel regulators of the ageing and senescence biomarker, p16.

In 2010, Cleo was awarded a Lecturership, and promoted to Senior Lecturer in 2016.

Cleo is the Academic Lead for The QMUL Phenotypic Screening Facility, managed by Dr Luke Gammon, and in 2018 became the Director of Graduate Studies for the Blizard Institute. She also organises our cross-campus forums on ‘Senescence and Ageing’ and ‘Extracellular Vesicles’

Summary

Recent and ongoing research projects:

Advanced age is the main risk factor for most chronic diseases in humans, but the basic machinery that drives ageing remains largely unknown. With the exception of pluripotent embryonic stem cells, primary cells in vitro and in vivo gradually lose the ability to divide. One of the key effectors of this process is p16, a master regulator of the cell cycle whose expression results in cellular senescence. The gradual accumulation of p16 expression during physiological ageing and several ageing-associated diseases promotes p16 as a robust biomarker of human ageing. Its locus, the INK/ARF locus, is intimately involved in the susceptibility to a broad range of ageing-associated diseases, including coronary artery disease and type 2 diabetes. Targeting cellular senescence represents an exciting strategy for promoting healthy ageing.

The regulated cell proliferation that is essential for human longevity contrasts with the uncontrolled growth of cancer cells. During early tumourigenesis, cells harbouring precancerous lesions often respond by activating tumour suppressors, such as p16, and entering a premature cell cycle arrest called oncogene-induced senescence. The establishment of this growth arrest relies on the timely activation of p16, a virtual hallmark of early stage neoplasia, and acts as a vital barrier to cancer progression. By illuminating the fundamental mechanisms that regulate senescence programmes we will further our understanding of how cells sense early carcinogenic events, and the interplay between cancer progression, healthy ageing and cellular rejuvenation.
