Abstract:
APPLICANT?S DESCRIPTION: This proposal describes technical approaches for
efficient and high throughput production of region specific genomic and cDNA
microarrays with the ultimate goal of deciphering cancer-associated genes
involved in various human neoplasias. The techniques will be applied to the
human 5q31-qter region for feasibility studies. This region and its homologous
region in mouse have been shown to be critical in mouse and human
hepatocellular carcinomas. We will take two independent approaches to reach the
goal of identifying genomic regions harboring genetic alterations and the genes
encoded by them. For production of genomic microarrays, we will isolate YAC and
BAC contigs in the 5q31-qter region and amplify by inter-Alu primers to obtain
a fair representation of this region. We will microarray these amplicons and
screen with probes obtained from normal and cancerous tissues (each with
different fluorochromes). The ratio of fluorescent intensities will be used to
identify amplified and deleted regions of the genome. For development of region-specific
cDNA arrays, we ill make use of genomic draft sequencing information to select all coding
sequences in the 5q31-qter region. We will array these enriched cDNAs and screen them
with cDNA probes derived from normal and cancerous tissues. The high throughput
production of genomic and cDNA microarrays will facilitate detailed genetic and
transcription mapping of cancer associated regions of the human genome.
PROPOSED COMMERCIAL APPLICATION:
Commercially available region specific microarrays will be offered to researchers who
concentrate on the regions of genome that are critical in human neoplasias. Therefore, the
ultimate goal of this project is to generate commercially available region specific, custom
made genomic and cDNA microarrays that can be screened with fluorescently labeled
genomic and cDNA probes to facilitate gene mapping and discovery efforts.
