The key result is that sample 105 includes a key gene called DamMT ( DNA methyltransferase ) while sample 439 lacked this gene.

Working with tiny worms, the laureates identified key genes regulating organ development and programmed cell death, a necessary process for pruning excess cells.
23.
These signals tell the developing cell to switch on the key genes and proteins that will govern its physical shape and biological characteristics.
24.
This research led to the discovery of gene silencing when an extra copy of a key gene yielded white rather than blue flowers.
25.
Takahashi used forward mutagenesis screening of mice treated with N-ethyl-N-nitrosourea to create and identify mutations in key genes that broadly affect circadian activity.
26.
In a discovery that could lead to powerful new vaccines and antibiotics, researchers have isolated a key gene that bacteria use to launch killer infections.
27.
The accidental " switching off " of key genes could be at least as important a cause of cancer as mutations, many researchers now believe.
28.
Researchers might cull smokers with ischemic heart disease to test the hypothesis that smoking elevates the disease risk by affecting the variants of certain key genes.
29.
Additionally, researchers looked at key genes involved in prostatic glandular and stromal growth, cell-cycle progression, apoptosis, hormone receptors, and tumor suppressors using a custom PCR array.
30.
Moreover, FGF21 could inhibit the transcriptional levels of the key genes involved in processing and nuclear translocation of SREBP-1c, and decrease the protein amount of mature SREBP-1c.
