Along with ORC, this protein binds to heterochromatic
structures, including centromeres and telomeres, which are important to cell division and chromosome maintenance.
If H3K9me at heterochromatic
ALU elements is detectable in plasma, such detection is not expected to indicate a disease-specific event.
Moreover, the striking similarity among the C-banding patterns found in the non-Andean regions (Table 3), restricted to three heterochromatic
pairs, suggests that the event of heterochromatin decrease may have taken place just once in the evolutionary history of T.
On the cytological level, during interphase, the chromosomes in animals, such as flies, are all joined together in a common heterochromatic
region, referred to as the chromocenter.
These histone modifications dictate local and global structure of chromatin, rendering it active and decondensed ( euchromatic ) or suppressed and compact ( heterochromatic
) by the recruitment of chromatin-binding proteins that recognize and associate with specific modifications.
Simultaneous fluorescent staining of R band and specific heterochromatic
regions (DA/DAPI-bands) in human chromosomes.
Last year this was updated to the MPSII, which allows a central only measurement (within 90 seconds on average) and gives a confident analysis on the result (much like the confidence indicators used for visual field analysis) with over 90% of patients giving an accurate reading the first time they have used this heterochromatic
flicker to measure macular pigment.
How nickel induces DNA methylation is not yet understood, but it has been proposed that nickel first induces chromatin condensation followed by de novo methylat ion of heterochromatic
DNA (Lee YW et al.
In dipterans, such as Drosophila Fallen, 1823 (Drosophilidae), it has been demonstrated that heterochromatic
sequences can be selectively underrepresented by active elimination during the development of polyploid chromosomes with a drastic reduction in copy numbers of some satellite sequences (Glaser et al.
Central to his findings is the importance of the progressive hetero-chromatinization of chromosomes, which he explains as a condensation of eu- and heterochromatic
A recent study in the Cyperales demonstrates that centromere-specific histone H3 is present at nearly even strengths along heterochromatic
regions of the chromosomes in Luzula nivea (L.
The densely brilliant magenta nucleolar-associated heterochromatic
DNA in Feuglen stained sections distinguishes the donor quail cells from host chick cells (Le Douarin, 1973a, b).
