IDENTIFICATION OF GENOMIC CHANGES MEDIATING MELANOMA DEVELOPMENT AND PROGRESSION

这个项目的目的仍然是确定

The purpose of this project continues to be the determination of the molecular basis of chromosome rearrangements underlying the genesis and progression of human malignant melanoma. Melanoma has the fastest growing rate of incidence of any cancer (next to lung cancer in women) in the Western world, and extraordinarily little is known about the molecular genetic changes underlying this important disease. This project can be divided into three component parts. 1) Molecular analysis of tumor progression. [This focuses on clonal progression identified by tissue dissection and comparative genomic hybridization, and on clonal karyotypic alterations in malignant melanoma]. 2) Identification of genes differentially expressed during growth, differentiation and progression. [This focuses on suppression of tumorigenicity of chromosome 6, cDNA subtraction/differential display, retroviral-mediated reversion of tumor suppression, and DNA microarray analysis of differential gene expression]. 3) Genomic analysis of chromosome 6 alterations. [This involves microdissection-based cloning of chromosomal breakpoints in melanoma, and other malignancies].
