A segment is defined over/under-expressed if it has an expression value which is significantly different between two conditions analyzed, and contains at least 3 individually over/under-expressed genes, e.g. genes which have expression values within the highest and the lowest 2.5th percentile.
BMP4 is expressed early in tooth development and has an expression profile which coincides with the shift of odontogenic potential from the epithelium to the mesenchyme during development of the tooth bud (15).
DDAH exists as two distinct isoforms, with DDAH I present in tissues expressing neuronal NOS, whereas DDAH II has an expression pattern similar to that of eNOS [ 11], thus making DDAH II characteristic of vascular tissue such as the heart and endothelium.
The ctenophore MHCIIa gene (PpiMHCIIa) has an expression pattern akin to that of "stem cell markers" (Piwi, Vasa…) and is expressed in proliferating cells.
In the rosid species Citrus, the situation is different; the gene belonging to the AGL6-like clade is expressed in both vegetative and floral parts while the euAGL6 gene has an expression restricted to floral tissues, similar to expression of the SEP3 gene.
Fennell has an expression that's half smile, half wince.
The girl has an expression that suggests she knows what's ahead for her.
His features might be considered plain, but he has an expression of serentiy & peaceful acceptance that makes him quite handsome.
