Alterations of DNA methylation were investigated in 6 urothelial carcinoma cell lines and 13 tumor tissues. The methylation of L1 LINE sequences was diminished in all cell lines (by 26 +/- 5%; range, 11-49%) and in most tumors (by 21 +/- 5%; range, 0-60%) compared to normal bladder mucosa. Hypermethylation of the calcitonin gene CpG island was restricted to(More)
Recent investigations have demonstrated p53 and Rb alterations in a subset of transitional cell carcinoma (TCC). Further genetic changes during tumor progression include overexpression of the c-myc gene in a significant number of mainly invasive bladder tumors. To study the possible interactions between these genes in TCC, urothelial cancer cell lines were(More)
The c-myc gene product is known to be involved in the regulation of cell proliferation and differentiation. Altered c-myc gene expression is a common event in a variety of tumors. This study was designed to investigate c-myc overexpression in transitional cell carcinoma (TCC). The first part was designed to investigate the frequency of c-myc overexpression(More)
ARE THE CHARACTERISTICS, GOALS, AND required skills of librarian-trained managers who choose careers in nonlibrary, but library-related, settings different from those of directors of libraries? This question will be explored by executives from two library-related organizations-one a not-for-profit library cooperative and one a private sector information(More)
