Research & Publications

01
An analysis of hormone- or carcinogen-metabolising enzyme expression in human prostate in relation to susceptibility to adenocarcinoma and an epidemiological investigation of lifestyle risk factors
02
Sections of the work have been presented in AACR (2004, 2005, 2006), UKEMS (2004), BPG (2004, 2006), URS (2005), EEMS (2005) and EAU (2006).
03
I have published part of the work in Cancer Letters, Biophysical Journal, Prostate Cancer and Prostatic Diseases and Prostate
04
“Inter- and Intra - individual differences in the gene expression of  phase I and phase II enzymes in the normal prostate”
05
To investigate whether a differential expression profile in phase I/II genes might explain zone susceptibility to Cap, we obtained tissue sets consisting of PZ and transition zone (TZ) of prostate. Levels of CYP1B1 and NAT1 were distinctly higher in PZ.  Immunohistochemistry confirmed the presence of CYP1B1 and NAT1 in the prostate.
06
“Survey of the incidence of major ailments amongst female partners of men diagnosed with prostate cancer: a pilot study”
07
A questionnaire study into the risk of common cancers in female partners of Cap males in North West England was conducted.  Rates for breast, colorectal or lung cancer among female partners were similar to estimates.  However, observed rates for breast or lung cancers among previous female partners were significantly (p ?0.001) elevated
08
“IR spectroscopy with multivariate analysis potentially facilitates the segregation of different types of prostate cell”
09
The IR spectral signature of PZ and TZ was obtained using Fourier- transform infrared (FTIR) micro-spectroscopy Following spectroscopic analysis, plotted clusters and their loadings curves highlighted marked spectral variation in the region containing DNA/RNA bands (?1,490-1,000 cm-1). TZ cells appeared to align more closely with Cap cells while exhibiting marked structural differences compared to PZ cells.
10
In conclusion, the prostate gland possesses the metabolic machinery to activate pro-carcinogens.  It is likely that environmental and/or dietary factors play an important role in the aetiology of Cap
