Research interests

Analysis of the molecular mechanisms underlying cancer.

The development of cancer is a highly complex, multistage mechanism involving mutations in the genes that control cell growth and differentiation. My interests centre on exploiting the classic mouse model of multistage skin carcinogenesis to investigate mutations in oncogenes and tumour suppressor genes that initiate cancer; assess which gene combinations induced the promotion phase giving benign tumours and identify genes that achieve malignancy. In either tissue culture [i.e. living skin equivalents] or transgenic mouse skin, genetic engineering technologies coupled to topical steroid application enable us to induced mutations at specific times and mimic the acquisition of additional genetic insults that drives cancer development in humans. A recent highlight focused on investigation of ras and fos oncogene cooperation with PTEN tumour suppressor gene loss. The ras/PTEN cooperation model gave benign tumours but conversion to carcinoma involved consequences of PTEN loss not ras, an important result if ras was the therapeutic target. Further, fos/PTEN co-operation produced a “dead end” benign tumour [keratoacanthoma], due to re-expression of tumour suppressor genes p53 and p21, which prevented malignant conversion and thus identified compensatory anti-cancer surveillance mechanisms in benign tumours possibly amenable to therapeutic induction. Another arm studies melanoma, where we seek to understand the interactions between mutations in either melanocytes, keratinocytes or both that drive early disease. Ideally, once we identify the specific gene combinations implicated in this complex process, it may result in accurate models to aid in the design and testing of novel therapies.
