Independent evolutionary origin of histone H3.3-like variants of animals and Tetrahymena

open access: yesNucleic Acids Research, 1994
All three genes encoding histone H3 proteins were cloned and sequenced from Tetrahymena thermophila. Two of these genes encode a major H3 protein identical to that of T. pyriformis and 87% identical to the major H3 of vertebrates. The third gene encodes hv2, a quantitatively minor replication independent (replacement) variant.

Comparing the Assembly and Handedness Dynamics of (H3.3-H4)2 Tetrasomes to Canonical Tetrasomes.

open access: yesPLoS ONE, 2015
Eukaryotic nucleosomes consists of an (H3-H4)2 tetramer and two H2A-H2B dimers, around which 147 bp of DNA are wrapped in 1.7 left-handed helical turns.

Transposable Elements, Inflammation, and Neurological Disease. [PDF]

open access: yes, 2019
Transposable Elements (TE) are mobile DNA elements that can replicate and insert themselves into different locations within the host genome. Their propensity to self-propagate has a myriad of consequences and yet their biological significance is not well-

Two distinct modes for propagation of histone PTMs across the cell cycle [PDF]

open access: yes, 2015
Epigenetic states defined by chromatin can be maintained through mitotic cell division. However, it remains unknown how histone-based information is transmitted.

Epigenetic regulation of centromeric chromatin: old dogs, new tricks? [PDF]

open access: yes, 2008
The assembly of just a single kinetochore at the centromere of each sister chromatid is essential for accurate chromosome segregation during cell division.

The HIRA complex that deposits the histone H3.3 is conserved in Arabidopsis and facilitates transcriptional dynamics

open access: yesBiology Open, 2014
In animals, replication-independent incorporation of nucleosomes containing the histone variant H3.3 enables global reprogramming of histone modifications and transcriptional profiles.

Novel improvement in iPSCs generation protocols through mouse gametogenesis epigenetic erasure mechanisms [PDF]

open access: yes, 2016
The main goal of this review is to describe gametogenesis epigenetic erasure mechanisms and to propose candidate molecules which can erase remaining epigenetic marks that enhace re-differentiation of cultured induced pluripotent stem cells (iPSCs) into ...
