Turkish Journal of Biology
This study investigated the immunohistochemical staining characteristics of glutathione-S-transferase (GST) alpha, pi, mu, and theta in prostatic acinar adenocarcinoma (PCA), prostatic intraepithelial neoplasia (PIN), and benign prostatic tissues from 19 patients. Relationships between GST isoenzyme expression in benign, PIN, and PCA tissue were examined by the Wilcoxon signed-rank test and clinicopathological data were examined by the Spearman correlation rank test. When the benign, PIN, and PCA tissues from these cases were compared according to their staining intensity, GST alpha, pi, mu, and theta expressions in tumor cells were significantly lower than in benign epithelial cells (P < 0.05). The GST alpha class displayed the lowest level of expression in PIN and PCA. Expression of GST pi was lower in PCA tissue than in PIN and benign epithelial tissue (P < 0.05). We hypothesize that carcinogenesis in the prostate results from impaired cellular handling of mutagenic agents owing to reduction or loss of expression of multiple GST isoenzymes and other detoxifying and antimutagenesis agents. This study confirms the down-regulation of GST isoenzymes in PCA of the prostate and shows that the loss of GST isoenzyme expression is a phenotype associated with malignant transformation. There was no statistical relationship between GST isoenzyme expression and the clinicopathological data (age, Gleason score, and total serum prostate-specific antigen levels) (P > 0.05).

This study was conducted to investigate the opportunity to utilize discriminant analysis in the selection of parent lines in hybrid maize breeding. For this purpose, top crosses were obtained by top-crossing 31 inbred maize lines with the FRMo.17 line in 2003. These hybrids were subjected to preyield trials in 2004. The same lines were subjected to observation tests in 2003 and 2004, and yield and yield components were determined. The obtained data were analyzed using the discriminant analysis method. The distances between the lines were determined according to D2 and canonical values. The TK-108, TK-110, TK-13, TK-347, TK-175, TK-157, and …
