In addition, CDX2 maintains the euchromatin
state for IFNT transcription (Sakurai et al.
In the second study, TEM examination revealed marked filopodia and euchromatin
nucleus in the experimental group .
Several hypotheses have been suggested to explain why these phenotypic anomalies are seen in balanced chromosome rearrangements, lt may be possible that the gene is broken and the position effects of gene or change in euchromatin
structure, loss or small deletions or duplications were not seen with normal cytogenetic methods (6).
12) reported that mono- and dimethylated residues were specifically localized at silent domains within the euchromatin
and that H3K9 trimethylation was more frequent in pericentric heterochromatin.
Deacetylation of histones by HDAC modifies the chromatin from an open gene-active euchromatin
structure to a closed gene-silenced heterochromatin structure, which may reduce the transcription of genes that suppress tumour growth.
The nucleus increased to 50 [micro]m and appeared almost completely transparent, with the euchromatin
staining very light blue.
Both of these types of epigenetic modifications work together to remodel the chromatin and partition the genome into two different functional domains-transcriptionally active regions collectively known as euchromatin
and transcriptionally inactive regions collectively called heterochromatin.
High GC content is a characteristic feature of active euchromatin
and transcriptional activity.
Synergistic increase in chromosomal breakage within the euchromatin
induced by an interaction of the benzene metabolites phenol and hydroquinone in mice.
Nuclei were oval with clearly visible heterochromatin, euchromatin
, and nucleoli.
Reduced exploration, increased anxiety, and altered social behavior: Autistic-like features of euchromatin
histone methyltransferase 1 heterozygous knockout mice.
Some large hyalinocyte nuclei had abundant euchromatin
, and some showed abundant heterochromatin in the central and the peripheral positions.
