Predicting a response to treatment in patients with lung cancer
Menarini-Silicon Biosystems announced the company’s DEPArray single-cell isolation technology played a key role in a study conducted by researchers from The University of Manchester to develop a model for predicting whether small-cell lung cancer patients will be sensitive or resistant to initial chemotherapy treatment.

Friendly Fire in the Pancreas
n type 1 diabetes, the body attacks its own insulin-producing cells. Scientists at Helmholtz Zentrum München, partner in the German Center for Diabetes Research, and their colleagues at Technical University of Munich have now reported in the journal ‘PNAS’ about a mechanism used by the immune system to prepare for this attack. They were able to inhibit this process through targeted…

Brain cell ‘executioner’ identified
Despite their different triggers, the same molecular chain of events appears to be responsible for brain cell death from strokes, injuries and even such neurodegenerative diseases as Alzheimer's. Now, researchers at Johns Hopkins say they have pinpointed the protein at the end of that chain of events, one that delivers the fatal strike by carving up a cell's DNA. The find, they say, potentially…

Nanoparticle creates ‘wave of destruction’ in cancer cells
Nanoparticles known as Cornell dots, or C dots, have shown great promise as a therapeutic tool in the detection and treatment of cancer. Now, the ultrasmall particles – developed more than a dozen years ago by Ulrich Wiesner, the Spencer T. Olin Professor of Engineering at Cornell University – have shown they can do something even better: kill cancer cells without attaching a cytotoxic drug.

Watching molecular machines at work
When one cell divides into two - that is how all forms of life are propagated - the newly born daughter cells have to be equipped with everything they will need in their tiny lives. Most important of all is that they inherit a complete copy of the genetic information from their mother cell. If this is not the case because a wrong number of chromosomes – on which the genetic information is…

First accurate simulation of a virus invading a cell
For the first time, scientists know what happens to a virus’ shape when it invades a host cell, thanks to an experiment by researchers at Penn State College of Medicine and University of Pittsburgh School of Medicine. Understanding how the virus shape specifically changes could lead to more effective anti-viral therapies.

A small implanted device could improve survival
A small device implanted under the skin can improve breast cancer survival by catching cancer cells, slowing the development of metastatic tumors in other organs and allowing time to intervene with surgery or other therapies. These findings suggest a path for identifying metastatic cancer early and intervening to improve outcomes.
Solid-State nanopores unravel twisted DNA mystery
Cancer thrives when mutated cells undergo frequent division. Most anti-cancer drugs work by inserting themselves in between the DNA base pairs that encode our genetic information. This process is known as intercalation, and it can result in subtle changes to the DNA molecule’s geometric shape or tertiary structure. These structural changes interfere with the DNA’s transcription and a cell’s…

Infra-red light to deteact early signs of oesophageal cancer
Researchers at the Cancer Research UK Cambridge Institute sprayed a dye on oesophageal tissue samples taken from people with Barrett’s oesophagus – a condition that increases the risk of developing oesophageal cancer. The dye sticks to healthy oesophageal cells but not to pre-cancerous cells. They then shone near-infrared light - which is just beyond the red colours that our eyes can normally…

Loophole for cancer cells
Many cancers only become a mortal danger if they form metastases elsewhere in the body. Such secondary tumours are formed when individual cells break away from the main tumour and travel through the bloodstream to distant areas of the body. To do so, they have to pass through the walls of small blood vessels. Scientists from the Max Planck Institute for Heart and Lung Research in Bad Nauheim and…

How tumors adapt to become more aggressive
One of the many reasons tumors are so difficult to treat is that they are able to adapt whenever they are exposed to unfavorable conditions. Hypoxia, or a lack of oxygen, is one example of a phenomenon that should weaken the tumor, but instead, the malignant cells are able to compensate and drive more aggressive disease behavior.

How proteins prevent communication between bacteria
They may be slimy, but they are a perfect environment for microorganisms: biofilms. Protected against external influences, here bacteria can grow undisturbed, and trigger diseases. Scientists at Kiel University, in cooperation with colleagues at the Hamburg University of Technology (TUHH) in Hamburg-Harburg, are researching how it can be possible to prevent the formation of biofilms from the…

Biotherapeutics strike cancer cell growth
Many drug treatments do not work due to their poor ability to reach their intended targets inside patients’ cells. To address this, researchers at Cardiff University’s Schools of Pharmacy and Pharmaceutical Sciences, and Biosciences have designed a highly efficient method to improve the delivery of therapeutic molecules into diseased cells such as those in stomach cancer, breast cancer and…

Microfluidic device tests effects of electric fields on cancer cells
Researchers at Massachusetts Institute of Technology research center in Singapore have developed a new microfluidic device that tests the effects of electric fields on cancer cells. They observed that a range of low-intensity, middle-frequency electric fields effectively stopped breast and lung cancer cells from growing and spreading, while having no adverse effect on neighboring healthy cells.

Researchers at the University of Bonn and the Ludwig-Maximilians-Universität of Munich have decoded a new mechanism of how the immune system can specifically attack pigmented cells of the skin.
