5. Study Description

Brief Summary
This project is about the detection of occult tumor cells in surgical margins of radical prostatovesiculectomy by analysing the methylation status of Glutathione S-transferase P 1 (GSTP1). After gland excision specimens are obtained from 9 defined areas of the prostatic fossa. The biopsies are divided into two parts. One part used for histopathological analysis and the other part for moleculargenetic analysis. Results will be correlated e.g. with tumor stage, Gleason Score and prostate specific antigen (PSA). The prostate-cancer-negative control group with bladder cancer.
Detailed Description
This project is about the detection of occult tumor cells in surgical margins of radical prostatovesiculectomy by analysing the methylation status of Glutathione S-transferase P 1 (GSTP1). After gland excision specimens are obtained from 9 defined areas of the prostatic fossa. The biopsies are divided into two parts. One part used for histopathological analysis and the other part for moleculargenetic analysis. Results will be correlated e.g. with tumor stage, Gleason Score and prostate specific antigen (PSA). The prostate-cancer-negative control group with bladder cancer. DNA ISOLATION DNA from biopsies stored by -80°C was isolated by using innuPREP DNA mini Kit (Analytik Jena, Jena, Germany) following protocol 1 of the manufacturer's instructions. DNA was eluted with 50 µl elution buffer. Concentration and purity were analysed by using Nanodrop 2000. DNA BISULFITE MODIFICATION DNA was modified by using EpiTect Bisulfite Kit (QIAGEN, Hilden, Germany) according to manufacturer's instructions. Samples were eluted once with 20 µl elution buffer. QUANTITATIVE METHYLATION SPECIFIC PCR Methylation status of GSTP1 is analysed by quantitative methylation-specific PCR (Q-MSP) using StepOnePlus Real-Time PCR System and StepOne Software v2.1 from Applied Biosystems (Darmstadt, Germany). Q-MSP was performed in duplicate analysing genes Actin and GSTP1. The primers' and testing probes' sequences used to amplify and detect hypermethylated GSTP1 were: 5'-AgTTgCgCggCgATTTC (forward primer), 5'-gCCCCAATACTAAATCACgACg (reverse primer) and 5'-CggTCgACgTTCggggTgTAgCg (taqman probe), labelled with fluorescence dye FAM. The primers' and testing probes' sequences used to amplify and detect Actin were: 5'-TggTgATggAggAggTTTAgTAAgT (forward primer), 5'-AACCAATAAAACCTACTCCTCCCTTAA (reverse primer),5'-ACCACCACCCAACACACAATAACAAACACA (taqman probe), labelled with fluorescence dye VIC. The Q-MSP was carried out at 50°C for 2 min., 95°C for 15 min. followed by 50 cycles of 95°C for 1s and 60°C for 1 min. As a positive control bisulfite-converted DNA of DU145 and LNCap were used. Blank reactions with destillated water, which replaced DNA, served as negative control (NTC).
