Euchromatin

Direct analogs of chemically modified bases that carry important epigenetic information, such as 5-methylcytosine (m5C)/5-methyldeoxycytosine (5mC), 5-hydroxymethylcytosine (hm5C)/5-hydroxymethyldeoxycytosine (5hmC), and N6 -methyladenosine (m6A)/N6 -methyldeoxyadenosine (6mA), are detected in both RNA and DNA, respectively.

Chromosomes are subdivided spatially to delimit long-range interactions into topologically associating domains (TADs). TADs are often flanked by chromatin insulators and transcription units that may participate in such demarcation. Remarkably, single-cell Drosophila TAD units correspond to dynamic heterochromatin nanocompartments that can self-assemble.

Chromatin organizes DNA and regulates its transcriptional activity through epigenetic modifications. Heterochromatic regions of the genome are generally transcriptionally silent, while euchromatin is more prone to transcription.

The Bowman–Birk protease inhibitors have recently attracted attention for their potential as cancer preventive and suppressing agents. They contain two canonical binding loops, both consisting of nine highly conserved resi-dues capable of inhibiting corresponding serine proteases.

“Epigenetics” as introduced by ConradWaddington in 1946, is defined as a set of interactions between genes and the surrounding environment, which determines the phenotype or physical traits in an organism, (Murrell et al., 2005;Waddington, 1942). Initial research focused on genomic regions such as heterochromatin and euchromatin based on dense and relatively loose DNA packing, since these were known to contain inactive and active genes respectively, (Yasuhara et al., 2005).
