Abstract

Genomic sequencing generated an increased interest in non-coding DNA. This
applies also to non-canonical DNA structures and their possible biological
functions. Here we propose to combine molecular biology, bioinformatics and the
latest computer technology in an effort to understand, predict and map the
occurrence of biologically important DNA structures in genomes. Motivated by our
previous research, we will focus on
non-canonical DNA structures (cruciforms,
triplex, slippage- and Z-DNA). We will improve (and where necessary develop)
tools for in silico prediction of these DNA structures. Predictions will be
verified by carefully planned laboratory experiments, focusing on promoter
regions of cancer-related genes (e.g. p53, MDM2, hsp90, EGFR) studied in the
applicant's laboratory. Our ability to rapidly analyze full genomes will come
from the use of special algorithms and applications built around FPGA
hardware-acceleration cards.

As a result, we will obtain annotations of
genomes for predicted structures, occurence of such structures in
oncogenes,
as well as new methods and hardware for wider applications of accelerated
sequence search.
