ROME, Aug. 17 (Xinhua) -- Two Italian researchers
announced Monday that they have identified a gene which plays a key role in the
development of stem cells and is also involved in the most aggressive forms of
brain tumors.
Antonio Iavarone and Anna Lasorella, researchers at
New York's Columbia University Medical Center, said the finding could help find
new treatment for brain tumors.
They said their work followed major research by other
scientists who had produced induced pluripotent stem cells, commonly abbreviated
as IPS cells or iPSCs, according to the ANSA news agency.
IPS cells are a type of pluripotent stem cell
artificially derived from a non-pluripotent cell, by inducing a "forced"
expression of certain genes.
The researchers, whose study will be published by the
prestigious journal Developmental Cell, confirmed that they had identified a
gene -- Huwe1-- which produces a protein with the same name.
"This protein is capable of destroying some of the
key proteins used to produce iPS and restart the transformation of stem cells in
adult cells," said Iavarone.
Huwe1 could be used to help other researchers find
new therapies for brain tumors, according the researchers.
"It appears to be indispensable for the proper
programming of brain stem cells. We saw that it helps develop the neurons in
mice embryos and noticed as well that it is eliminated when the most malignant
type of brain tumor -- Glioblatoma multiforme (GBM) -- begins to develop in
humans," said Iavarone.
GBM is the most common and most aggressive type of
brain tumor in humans.
