For example, genetically engineered organisms used in the research laboratory to develop new chemical synthesis methods are not likely to require the
same level of public dialogue as products that have more uncertainty associated with them, such as organisms with
gene drives, which enhance organisms» ability to pass certain genetic traits on to their offspring.
Researchers analyzed the genomes of 16 related orange and white tigers in captivity, fully mapping those of the three parent tigers to show that a mutation in one pigment
gene called SLC45A2 is at play — the very
same gene that
drives lighter coloring in people of European ancestry, chickens, and some mice.
But recent work shows that while these cancers lack estrogen receptors, progesterone receptors, and aren't
driven by the
gene HER2, up to a third of these tumors express the androgen receptor — clinical trials are underway to inhibit the androgen receptor in these tumors in much the
same way that the drug Tamoxifen inhibits estrogen receptor in estrogen - receptor - positive breast cancers.
In spite of the difference between the cell functions responsible for giving rise to a tumour and for the metastasis of this
same tumour, studies at IRB Barcelona using the fly Drosophila melanogaster reveal that some
genes can
drive both phenomena.
A self - sustaining method would require the use of a
gene drive designed to persist in the environment and spread within the target population, but with some risk of spreading into a non-targeted area where that
same species may be desired.
Although this natural
gene drive is unpredictable and scattershot, Burt showed that certain tricks of molecular biology could achieve the
same results: causing a
gene to be inherited by many more organisms through many generations than standard genetics and natural selection allow.
Implementing just sterile male and RIDL would take years and would, in the interim, allow development of the
gene drive technologies whilst at the
same time
driving down mosquito populations and thereby reducing the current pressure on threatened bird species.
I commend GM for adapting its Australian Holden Commodore for North American duty, and I can't wait to
drive the 2010 Camaro with the
same genes.
