atugen AG, a private company focused on the elucidation of disease pathways, today announced the identification of a novel cancer target that appears to play an important role in tumor growth and metastasis. atugen’s research group has demonstrated that inhibition of the novel target, Atu027, which has homology to protein kinases, results in blockage of tumor growth of human prostate carcinoma cells in orthotopic mouse models. atugen has demonstrated that human prostate tumor cells engineered to express siRNA molecules against the kinase shows significant reduction or even complete lack of secondary tumors indicating a role of the kinase in tumor progression and metastasis.
The novel target, Atu027, is the result of the companys internal research program on the phosphatidylinositol 3-OH kinase (PI 3-K) pathway. The approach was presented at the Cold Spring Harbor Laboratory’s Tumor Suppressor August 2002 Meeting in Cold Spring Harbor, NY. PI 3-K is a central signal transduction molecule controlling a wide range of cellular responses including contributing to increased malignant behavior of cancer cells.
The identification and functional validation of the kinase as PI 3-K downstream effector molecule underscores the strength of the atugen approach to find novel targets. The use of the company’s proprietary mRNA knockdown technologies (GeneBlocs® antisense molecules, improved synthetic siRNA, vector expression systems for siRNA, ribozymes and superior transfection reagents) together with atugen’s expertise in gene function elucidation has to date resulted in 19 functionally validated cancer targets that act in the PI 3-K pathway.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
