For example, ectopic expression of abd-A, which specifies the NB6-4a lineage, down-regulates levels of the G1 cyclin, CycE [ 38].
Their branches represent evolving lineages, some of which eventually die out while others persist in themselves or in their derived lineages down to the present time.
Indeed, direct cases of maintained dual complementarity, in spite of high variability of the second bases in various Bacteria, Archaea and Eukarya lineages (down to the different species level), suggest that the dual complementarity maintenance phenomenon is largely invariant across (hence, independent of) the domains of life.
For instance, comparing the protein sequences encoded in bacterial genomes has helped to predict the metabolic capabilities of different lineages (Downs 2006).
PU.1 has been extensively studied within the haematopoietic cell lineage with down regulation of this transcription factor leading to leukaemic transformation [21,30].
That's how it works in Chicago, the baseball team you root for is a part of your lineage, passed down from one generation to the next.
Monocyte differentiation program toward DCs lineage includes down-regulation of CD14, and de novo synthesis of CD1a.These major changes were unaffected by the presence in the culture medium of idv, apv or nlfv.
To determine the degrees of expansion of these two classes among monocot and dicot plant lineages, we broke down the phylogeny into ancestral units according to the method.
Biallelic occlusion may be key to defining and restricting the phenotypic identities of cells by stably shutting down lineage-inappropriate genes that might otherwise become active.
In some lineages mutations have shut down one blood type or another.
The incidence of wild Fov in soils associated with wild Gossypium also varied among the five lineages, ranging from c. 40% in lineages A and E, down to 11% and 2% in lineages B and C respectively.
