Background: Currently, ARTs are of indispensable importance in treatment of human infertility. While ARTs are considered to be safe, some studies suggest that ARTs manipulations may perturb the epigenetic information and subsequently the health of the offspring. To examine these events further, this study was conducted to assess the effect of superovulation, in vitro culture and vitrification o...

We discuss the regulation of the histone genes of the budding yeast Saccharomyces cerevisiae. These include genes encoding the major core histones (H3, H4, H2A, and H2B), histone H1 (HHO1), H2AZ (HTZ1), and centromeric H3 (CSE4). Histone production is regulated during the cell cycle because the cell must replicate both its DNA during S phase and its chromatin. Consequently, the histone genes ar...

a study was made on the interaction between histon h1 and sodium n-dodecyl sulphate (sds) in the presence of sodium arsenate inside a phosphate buffer of ph 6.4, using spectroscopy and equilibrium dialysis at 27 °c. the binding data has been used to obtain the gibbs free energy in terms of a theoretical model based on the wyman binding potential. the binding data hs been analysed in terms of hi...

Histone proteins are key elements in the packing of eukaryotic DNA into chromosomes. A little understood control system ensures that histone gene expression is balanced with DNA replication so that histone proteins are produced in appropriate amounts. Disturbing or disrupting this system affects genome stability and gene expression, and has detrimental consequences for human development and hea...

Linker histone H1 is a fundamental chromosomal protein involved in the maintenance of higher-ordered chromatin organization. The exchange dynamics of histone H1 correlates well with chromatin plasticity. A variety of core histone chaperones involved in core histone dynamics has been identified, but the identity of the linker histone chaperone in the somatic cell nucleus has been a long-standing...

The interaction between histone and nonhistone chromatin proteins has been investigated by histone affinity chromatography, a technique that avoids precipitation of histone l nonhistone complexes. When nonhistone proteins labeled with 32P are loaded directly on histone-Sepharose columns, no binding of radioactivity to the column is observed. However, if labeled nonhistone proteins are mixed wit...

Histone modifications play important roles in chromatin remodeling, gene transcriptional regulation, stem cell maintenance and differentiation. Alterations in histone modifications may be linked to human diseases especially cancer. Histone modifications including methylation, acetylation and ubiquitylation probed by ChIP-seq, ChIP-chip and qChIP have become widely available. Mining and integrat...
