Sentence examples for marks of histone from inspiring English sources

Consistent with this data, the P1 promoter of PEMT showed the activation marks of histone methylation in CD4+ T-cells, whereas the P2 promoter did not (Figure 9B).

Several proteins have been shown to bind and readout marks of histone H3Lys4 methylation.

At gene promoters, deposition of both the repressive H3K27me3 and activating H3K4me3 marks of histone modifications shows a dependence on HP1a.

Next, one might look at RNA polymerase II (RNAP II) occupancy (34, 35) at the genes of interest, to determine whether they are actively transcribed under the assayed condition and corroborate those results with marks of histone H3 trimethylation at lysine 4 (H3K4me3) and histone H3 acetylation at lysine 4 (H3K4and and lysine 9 (H3K9ac), which mark active promoters (28, 36, 37).

With this in mind, we developed genetically encoded molecular biosensors based on the split-enzyme complementation approach for in vitro and in vivo imaging of lysine 9 (H3–K9 sensor) and lysine 27 (H3–K27 sensor) methylation marks of histone 3.

An important insight into the epigenetic control of insulin gene expression came from the observation in human islets that a surprisingly large region of about 80 kb around the insulin gene is very enriched with marks of histone acetylation and H3K4 dimethylation [ 21].

The notion that cell-type differentiation requires heterochromatin, as defined by the conserved mark of histone H3K9 methylation and its ligand HP-1, may need revision.

A more recent ChIP-seq study has further confirmed that CTCF marks boundaries of histone methylation domains [32].

Here we have investigated the genome-wide occurrence of two histone marks, acetylation of histone H3K9 and K14 (H3K9andand H3K14ac), in mouse embryonic stem (mES) cells.

Such marking of histones (as are acetylation, phosphorylation and ubiquitination of specific histone residues) conveys heritable transcription patterns (expression or silencing) in an epigenetic manner.

The KDM4D-dependent increase in the mutation frequency might be related to: (i) changes in the methylation marks of either histone other than H3K36me3 and/or non-histone proteins.
