The atlas should enable researchers to define different regions of the brain, far more than can at present be recognized by anatomists, based on the pattern of genes that are active in them.
Unfortunately, it is not possible to look at the expression pattern of genes in Neanderthals, and it probably never will be.
From the pattern of genes affected, Villeda traced the mechanism back to a master regulator in the brain, a protein known as CREB, which behaves like a switch that turns on many genes at once, and is instrumental in memory and learning from birth.
Figure 1 Expression pattern of genes involved in momilactone biosynthesis and MAPKKs upon UV exposure.
This adaptation is associated with changes in the expression pattern of genes and their protein products.
a UV induced expression pattern of genes involved in Phytoalexin biosynthesis, OsKSL4, CYP99A3 and OsMAS in rice leaves as shown by RT-PCR analysis.
These lines were used to investigate the effect of OsMKK6 EE over expression, on UV inducible expression pattern of genes involved in PA biosynthesis.
This enzymatic profile is correlated with the expression pattern of genes encoding four hemicellulases (two xylanases, one arabinosidase and one esterase) produced by T. xylanilyticus during growth.
Gene profiling on microarrays revealed important alterations in the pattern of genes expressed by tissue-engineered corneas in response to wound healing.
The test, which looks at the signature pattern of genes switched on and off in blood cells triggered by the tumour, can sort the "tigers" from the "pussycats".
Using a DNA chip, or microarray, containing about 7000 gene sequences, the researchers compared the pattern of genes active in the conquered tumors versus the deadly ones.
