HMGB1 for the treatment of tumors

09.07.2013
The High Mobility Group B1 (HMGB1) protein belongs

to the High Mobility Group (HMG) family of nuclear proteins, which was named due to the unusual high mobility of its members in SDSpolyacrylamide gel electrophoresis (SDS-PAGE). These proteins are, second to histones, among the

most abundant proteins associated with chromatin and they play an architectural role in the nucleus of the eukaryotic cell in that they bend, distort or otherwise modify the conformation of DNA, thereby also modifying the binding of transcription factors to DNA. HMG proteins have been implicated in the genesis of various disorders, like several kinds of benign tumors and autoimmune diseases. For the HMGB1 proteins, several structural motifs have been described: two DNA-binding domains (box A and box B), two nuclear localization sequences, and a C-terminal acidic domain. The HMGB1 proteins can be extensively posttranslationally modified by acetylation, methylation, ADPribosylation, phosphorylation or glycosylation. Acetylation of the nuclear localization sites is the signal that causes the HMGB1 protein to be actively secreted from activated cells of the immune system. Besides active secretion, HMGB1 is also released passively from necrotic cells.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
