(Ivanhoe Newswire) -- New insight into the most common cancer in
young children may lead to innovative treatments.
Previous research has shown amplification of a gene called MYCN in patients
with neuroblastoma usually means a poor prognosis. Researchers sought to
find out if other genes played a role in this type of cancer, called MYCN-amplified
neuroblastoma.
The researchers screened almost 200 genes that interact with MYCN. They
found a gene called AURKA is required for the growth of deadly MYCN-amplified
neuroblastoma cells. AURKA encodes the enzyme Aurora A, which is
dysregulated in cancer cells like neuroblastoma cells.
"Our results show that stabilization of N-Myc [MYCN] is a critical oncogenic
function of Aurora A in childhood neuroblastoma," Dr. Martin Eilers, of the
University of Wurzburg in Germany, was quoted as saying. "The challenge will
now be to find ways to interfere with this function in order to find new
approaches for the therapy of these tumors."
MYCN causes cancer by disrupting control of cell division and
differentiation, causing certain neural cells to continue dividing
uncontrollably.
