HP1: Facts, open questions, and speculation
The demonstration, over a decade ago, that HP1 is a highly conserved constituent of heterochromatin was accompanied by the explicit view that this protein plays a pivotal role in epigenetic regulation (P.B. Singh, J.R. Miller, J. Pearce, R. Kothary, R.D. Burton, R. Paro, T.C. James, and S.J. Gaunt, 1991, Nucleic Acids Res. 19, 789-794).

Mechanisms of functional promiscuity by HP1 proteins [PDF]
Heterochromatin protein 1 (HP1) proteins were originally identified as critical components in heterochromatin-mediated gene silencing and are now recognized to play essential roles in several other processes including gene activation. Several eukaryotes possess more than one HP1 paralog.

Background Histone lysine methylation plays a fundamental role in chromatin organization and marks distinct chromatin regions. In particular, trimethylation at lysine 9 of histone H3 (H3K9) and at lysine 20 of histone H4 (H4K20) governed by the histone ...

Human heterochromatin protein 1 isoforms HP1(Hsα) and HP1(Hsβ) interfere with hTERT-telomere interactions and correlate with changes in cell growth and response to ionizing radiation [PDF]
Telomeres are associated with the nuclear matrix and are thought to be heterochromatic. We show here that in human cells the overexpression of green fluorescent protein-tagged heterochromatin protein 1 (GFP-HP1) or nontagged HP1 isoforms HP1(Hsα) or HP1 ...

On the closedness of approximation spectra [PDF]
Generalizing Cusick's theorem on the closedness of the classical Lagrange spectrum for the approximation of real numbers by rational ones, we prove that various approximation spectra are closed, using penetration properties of the geodesic flow in cusp ...

Characterisation of a Helicobacter pylori phage (HP1) [PDF]
The infection of two Helicobacter pylori strains with a phage-containing supernate of the lysogenic H. pylori strain IMMi 290/89 resulted in a lytic cycle and propagation of phage HP1. In negatively-stained preparations, the empty phage heads measured 55-60 nm in diameter and mature heads measured 50 nm. The flexible, striated phage tail was c.

Phase transition between non-extremal and extremal Reissner-Nordstr\"om black holes
We discuss the phase transition between non-extremal and extremal Reissner-Nordstr\"om black holes. This transition is considered as the $T \to 0$ limit of the transition between the non-extremal and near-extremal black holes.

Experimental data from flesh quality assessment and shelf life monitoring of high pressure processed European sea bass (Dicentrarchus labrax) fillets [PDF]
Fresh fish are highly perishable food products and their short shelf-life limits their commercial exploitation and leads to waste, which has a negative impact on aquaculture sustainability.
