You're now dealing with substances so small they can target cells or organs without damage to surrounding tissue.
Early experiments suggested that an antisense drug could precisely target cancer cells, but Crooke was unable to reproduce this nascent work in his SmithKline lab.
This variant was able to target selectively cancer cells in humans.
ECONOMIST: The prospects for using genes as a therapy may be improving
If these can be identified, they hope that the number of these on the surface of tumour cells can be boosted, so they present an obvious target for "killer" cells in the body's immune system.
Figure out a way to isolate these mutant cells and target only them, Dirks says, and maybe cancer can be stopped outright--and the kids he treats might stop dying so soon after he operates.
In the test tube, antisense compounds failed to enter the cells containing the target genes.

The treatment involves taking a patient's T-cells, the infection- and disease-fighting cells of the immune system, and genetically modifying them to target a protein called CD19, which is present on ALL cells.
The viruses used to deliver the light-sensitive proteins can be engineered to target very specific clusters of brain cells.
New York City-based Stemline Therapeutics develops treatments that target both cancer tumors and cancer stem cells, which generate tumors.
For example, monoclonal antibodies target and kill tumors while sparing healthy cells.
FORBES: A Coming Renaissance In Pharmaceutical Research & Development?
Researcher Dr Ying Li said it might also be possible to use the technique to target drug treatments more precisely at cancer cells.
Mice given the modified cells produced more than six times the number of "killer T" cells, which are immune cells produced to neutralise a target.
They combined conventional PET imaging, which requires a radioactive tracer to highlight the brain's metabolic activity, with other recent advances in the genetic engineering of brain cells that allows them to target specific brain circuits in lab animals.

Once they have found a tumour, they stick to their target like glue, even piggybacking on malignant cells as these move through the body.
It has already expanded production capacity for the modules, which are made up of interconnected solar cells, to a previously announced target of 700 megawatts.
These were converted back into T-cells which should also have the ability to target the cancer or HIV.
Another use of the oxygen treatment has been assisting radiotherapy by "feeding" tumours, which are often faster growing than other cells, making them making them easier to target, she added.
That makes it tougher to target, separate out and kill viruses without also killing the cells they have infiltrated.
Cerovive is the first drug to target the toxic compounds that are produced by the starved brain cells--and it can be used as long as six hours after the stroke.
The firm has set itself the target of cutting costs by the 90% needed to make fuel cells competitive in vehicles by 2003.
In some cells (like the thin film CdTe ones) the target metals are indeed in a thin film which could conceivably be washed off with the right reagent.
FORBES: Loser Chemicals (No, Really) to Recycle Solar Panels
The two new antibodies target one of the proteins that form a spike used by HIV to infect cells.
Wong (now at Stanford University) figured the mutated gene might make an ideal target for a vaccine, as it creates an abnormal protein not seen in healthy cells.
The liver is Geron's first target in its plan to use cloning technologies, called nuclear transfer, to produce transplantable cells and organs from the patient's own body.
Benlysta is delivered directly into a vein (intravenous infusion) and is the first inhibitor designed to target B-lymphocyte stimulator (BLyS) protein, which may reduce the number of abnormal B cells thought to be a problem in lupus.
FORBES: Human Genome Sciences' Benlysta Approved To Treat Lupus
All three drugs target the epidermal growth factor receptor (EGFR), a protein that is over-expressed in cancer cells.
