regulatory networks mirna
Regulatory Networks & miRNA
  • Gene Regulator Networks control the functions of the cell
  • Molecular Signals are used for intracellular communication
  • Micro RNA (miRNA) is used as a molecular signal typically to inhibit transcription or translation of other molecular signals or genes.
  • Alien miRNA introduced into the cell could disrupt the regulatory networks within the cell resulting in a cancerous cell.
  • miRNA is typically between 18 – 25 base pairs in length
retroviruses
Retroviruses
  • Retroviruses enter and infect cells as RNA the convert themselves into double stranded DNA and insert themselves into the host genome.
  • Once the retrovirus has inserted itself into the host genome, the host will make new copies of the virus that can infect other cells.
retroviral mirna
Retroviral & miRNA
  • Retroviruses can pick up regions of their host during the replication process.
  • These regions may contain gene segments that can act as miRNA
  • 4 Essential genes of a retrovirus (GAG, PPT, POL and ENV)
  • Unspecific gene regions (U3 and U5)
  • Repetitive sequence regions (R)
  • The U3 and U5 regions are locations

where miRNAs could be located

gpu search tool
GPU Search tool
  • Development of a GPU based search tool.
  • The search tool will be written in both CUDA and OpenCL to determine the most efficient GPU method for the search tool.
  • The algorithm will use the 4 genes, gag, ppt, pol and env to locate the retroviruses.
  • Once these regions are found we will search the regions beteween the 4 genes against the miRNA database for matches with high confidence.
  • The tool will search for both the miRNA and its reverse compliment to also find potential interfering RNAs (RNAi). When a match is found the tool will report the match location and miRNA sequence.
  • It is hoped that this information will help in the development of cancer treatments.
