Poxvirus hijacks cell movement to spread infection

13-Nov-2018

Vaccinia virus, a poxvirus closely related to smallpox and monkeypox, tricks cells it has infected into activating their own cell movement mechanism to rapidly spread the virus in cells and mice, according to a new UCL-led study. The findings explain how the virus mimics infected cells' own ...

Mutant protein tackles DNA guardian to promote cancer development

How tumour development is driven by mutations in important gene in preventing cancer

09-Nov-2018

Melbourne scientists have discovered how tumour development is driven by mutations in the most important gene in preventing cancer, p53. The research revealed that in the early stages of cancer, mutant p53 'tackles' the normal p53 protein and blocks it from carrying out its protective role. As a ...

'Mushrooms' and 'brushes' help cancer-fighting nanoparticles survive in the body

Optimal polymer coating to preserve nanoparticles

25-Oct-2018

For a number of innovative and life-saving medical treatments, from organ replacements and skin grafts to cancer therapy and surgery, success often depends on slipping past or fending off the body's immune system. In a recent development, aimed at aiding cancer detection and treatment, Drexel ...

Principles of limb regeneration in salamanders show link to mammals

01-Oct-2018

Scientists have long argued over which cells enable salamanders to grow back lost limbs. By tracking lineages and characterising individual cells, researchers could now show that connective tissue cells develop stem-cell-like properties and underlie the regeneration of legs. Among all four-legged ...

Taking out the (life-threatening) garbage

Bacteria eject trash to survive

28-Sep-2018

Scientists have known for decades that certain bacteria produce small spherical versions of themselves. Although they lack basic materials to reproduce or function like normal cells, recent interest in such "minicells" has spiked due to their proficiency as nano-sized delivery tools for drugs and ...

Researchers combine light and X-ray microscopy for comprehensive insights

11-Sep-2018

Researchers at the University of Goettingen have used a novel microscopy method. In doing so they were able to show both the illuminated and the "dark side" of the cell. The team led by Prof. Dr. Tim Salditt and Prof. Dr. Sarah Köster from the Institute of X-Ray Physics "attached" small ...

Protein modifications pointing to cancer

29-Aug-2018

Researchers from the University of Zurich can, for the first time, precisely characterize the protein modification ADP-ribosylation for all proteins in a tissue sample. The changes, which are a typical reaction to stress, provide information about the condition of a cell. Together with the ...

Microfluidic chip for analysis of single cells

21-Aug-2018

A few little cells that are different from the rest can have a big effect. For example, individual cancer cells may be resistant to a specific chemotherapy—causing a relapse in a patient who would otherwise be cured. In the journal Angewandte Chemie, scientists have now introduced a ...

3D analysis of retinal tissue shows how to keep shape during organ growth

20-Aug-2018

During the early development of an embryo, many tissues and organs already form their final shape. This shape has to be maintained while the organism keeps growing. As the correct shape of a tissue is often essential for its proper function, it is crucial to understand how it remains unchanged ...

New Method Refines Cell Sample Analysis

Innovation in the field of biomedicine

06-Aug-2018

Researchers at the University of Zurich have developed a novel method which increases more than tenfold the number of proteins that can be visualized per sample, making it possible to generate a comprehensive map of cellular organization across the various cellular states. This highly ...
