Overview

This Drosophila model of malignant glioma uses the GAL4/UAS system to drive expression of an activated form of Dmel\Ras85D (the allele Ras85DV12) in glial cells. The RAS proteins control signaling pathways that are key regulators of several aspects of normal cell growth and malignant transformation. The constitutively active Ras85DV12 is analogous to oncogenic mutations found in orthologous human RAS proteins KRAS, NRAS, and HRAS.

The human genes Hsap\HRAS and Hsap\KRAS have been introduced into flies, but have not been characterized in the context of this disease model.

Expression of activated Dmel\Ras85D in glial cells, effected by RNAi, results in numerous glial neoplasias detectable at the larval stage; brain tumors cause early lethality in the pupal stage.

Molecular information

The RAS proteins are members of a large superfamily of low-molecular-weight GTP-binding proteins. The RAS proteins control signaling pathways that are key regulators of several aspects of normal cell growth and malignant transformation. Three members of the RAS family, HRAS, KRAS and NRAS, are found to be activated by mutation in human tumors. These three members are very closely related, having 85% amino acid sequence identity (Downward, 2003; pubmed:12509763).

    D. melanogaster Gene Information (1)
    Gene Snapshot
    Ras oncogene at 85D (Ras85D) encodes a protein that acts downstream of several cell signals, most notably from Receptor Tyrosine Kinases, to regulate tissue growth and development. When abnormally activated it can direct developmental defects and tissue hyperplasia, mimicking aspects of human disease including Rasopathies and cancer, respectively.

    Comments on ortholog(s)

    High-scoring ortholog of human genes KRAS, HRAS, and NRAS (many to many; multiple paralogs and orthologs in both species). Dmel\Ras85D shares 78-86% identity and 86-92% similarity with KRAS, HRAS, and NRAS; for these three human genes, Ras85D is the highest-scoring ortholog in Drosophila.
