Children with the disease have a genetic mutation that causes them to produce the protein progerin, which blocks normal cell function.
Now, I understand that cancer derives from a normal body cell, but it seems kind of a stretch to say that we're all born with cancer cells.
If incorporated into a living cell, the stored DNA data might be changed or erased by the normal process of cell biology.
The drug works by inhibiting an enzyme called the proteasome, stopping the normal progression of cell division and causing cancer cells to self-destruct.
If a compound could be found that bound to Tsg101 without disrupting the normal functioning of the cell, it might prevent HIV from spreading.
The team believe that not only do the growth factors play a key role in development of the central nervous system, but also that too much of them may disrupt the normal process by which a cell develops into the correct type and moves to the right area, and dies at the right time.
Large amounts of EGF, ten or more times normal production, can trigger a cell to grow uncontrollably.
These latch on to a protein that is expressed often in cancer cell but not in normal ones.
FORBES: Seattle Genetics Scores Win For Smart-Bomb Cancer Drugs
Large amounts of EGF, as much as 10 to 100 times the normal production, can trigger a cell to grow uncontrollably.
This happens during the production of sex cells, and its effect is to halve the number of chromosomes in a cell (the number returns to normal when two sex cells combine during fertilisation).
Both breast-fed and formula-fed babies who had been given n-3 fatty acid enriched egg yolks had 30-40% greater red cell membrane DHA levels than those fed normal egg yolks.
The small study, published in the Journal of American Medical Association, is the first to look specifically at how electromagnetic radiation from cell phones affects glucose metabolism, a normal function, in the brain.
In December, it completed a merger with Aclara Biosciences, which is looking at differences between normal and cancer cells to determine which signaling pathways a cancer cell is exploiting for replication.
While riding the bus, my cell phone signal suddenly went out, which is not normal, and continued to search for a signal for 15 minutes.
The study also found other evidence that brain cell death was at a higher level in the rats with a normal diet.
They produced a lively and, to all intents and purposes, normal sheep, known as Dolly, from the nucleus of a mammary-gland cell.
Sometimes it is a normal gene that directs the production of a hormone, such as insulin, or of the cell machinery which that hormone stimulates, such as the insulin receptor.
Reproductive cloning, which created Dolly the sheep in 1997, involves transferring the nucleus of an adult cell into an egg, giving the resulting embryo a full set of genes without the normal sperm-meets-egg fertilisation step.
With the help of Chiara Cirelli, who also works at the University of Wisconsin, Dr Tononi has created a mutant fruit fly that sleeps only two or three hours a night. (A normal fly sleeps between eight and 14 hours.) The mutation itself is in a gene for a nerve-cell protein of a type known as an ion channel.
