Ricin only Lethal in Combination with Sugar

The plant toxin ricin is one of the most poisonous naturally occurring proteins, making it an extremely dangerous bioweapon. Ricin attacks have made the headlines a number of times over the years, including the spectacular "umbrella murder" in London in the 1970s, or more recently the ricin letters addressed to

Multifunctional Nano Sized Drug Carriers Based on Reactive Polypept(o)ides

In cooperation with researchers from the University of Tokyo and Gutenberg Research Awardee Prof. Kazunori Kataoka, Chemists from Mainz have been able to demonstrate that reactive polypept(o)ides constitute ideal building blocks to control morphology and function of carrier systems in a simple but precise manner. Polypept(o)ides (polysarcosine-block-polypeptide copolymers) have emerged

‘Missing Link’ Explains How Viruses Trigger Immunity

The research team demonstrated a protein called SIDT2 was crucial for cells to detect viral components in their environment, and initiate an immune response to reduce the virus' spread. As well as being an important part of the intricate 'arms race' between viruses and our immune system, the finding could inform

Protein that Extends Life of Yeast Cells

For about one hundred years it has been known that nutrient restriction and moderate stress can significantly prolong life. The researchers led by Prof. Mihaela Zavolan and Prof. Anne Spang, both at the Biozentrum of the University of Basel, have discovered how the transcription factor Gcn4, a protein that regulates

Fast Forward Aging Due to DNA Damage

The heredity substance DNA is the blueprint of our life. Like an instruction manual it contains all the information needed for cells and the body to function properly. In the process, the DNA is always exposed to threats like UV light, pollutants and damage by metabolic byproducts. Many of those

Repetitive Elements Shape Embryonic Chromatin Landscape

The researchers specifically investigated the role of so-called LINE1 (L1) elements, the most abundant retrotransposon family in mammals.* "We already knew L1 elements to be highly expressed in early embryogenesis and so we wanted to know if this transcription is important in the events taking place in the early embryo"
