Cells are the basic building blocks of life – and, as such, they have been the object of intense study since the invention of the optical microscope in the 17th century. The development of mass spectrometry (MS) methods – those which define the chemical composition of cells – represented a further milestone for research in the field of cell biology. In the latest issue of the journal Nature…
Neurons of the central nervous system (CNS) shut down their ability to grow when they no longer need it; this is commonly accepted knowledge. This occurs normally after they have found their target cells and established synapses. However, recent findings show that old nerve cells have the potential to regrow and to repair damage similar to young neurons. The underlying mechanisms for this…
Researchers identified how to kill therapy-resistant cells in hypoxic tumors and in cells arising in the von Hippel-Lindau hereditary cancer. In a recent publication in PNAS, the Susanne Schlisio group at Department of Microbiology, Tumor and Cell Biology (MTC) in Collaboration with Cancer Center Karolinska (CCK) at Karolinska Institutet, the Edinburgh Cancer Research UK Centre, and the…
The team of the Heinz Nixdorf Chair of Biomedical Electronics at the Technical University of Munich focuses on innovative diagnostic tools to accelerate the development towards personalized medicine. Therapies tailored to the individual patient – this is the future not only of oncology but of many medical disciplines. “At this point, however,” concedes Professor Dr Oliver Hayden,…
Nearly 90% of all cancer patient deaths are due to metastasis. A study from Uppsala University shows that a process that allows the cells to metastasise is aided by the synthesis of new ribosomes, the cell components in which proteins are produced. The results open the possibility for new treatment strategies for advanced cancers. The study is published in Nature Communications. As tumours…
Researchers at Mount Sinai have developed a novel approach to cancer immunotherapy, injecting immune stimulants directly into a tumor to teach the immune system to destroy it and other tumor cells throughout the body. The “in situ vaccination” worked so well in patients with advanced-stage lymphoma that it is also undergoing trials in breast and head and neck cancer patients, according to a…
Scientists at Newcastle University believe it may be possible to reverse the damage in the heart caused by ageing. New research, which has been published in the journal EMBO, could suggest a new way of preventing heart failure in older patients. Heart failure occurs when the heart is not pumping blood around the body as well as it should, most commonly when the heart muscle has been damaged –…
In breast cancer, one of the most common cancers in women, tumors contain a small amount of so-called cancer stem-like cells (CSCs). Being able to eliminate breast-cancer stem-like cells in a targeted way is essential for developing successful therapies — conventional treatments, such as chemotherapy or radiotherapy followed by drug intake, do not target CSCs. A better understanding of the…
How can we detect the first signs of disease as early as possible? Could closer investigation at the cellular level help to quickly prevent disease progression through appropriate treatment? The European Union is now investing a million euros over a one-year period to devise the plan for a fundamentally new approach to understanding the constant changes within cells and their relationships to one…
Portland State University (PSU) researchers have made a significant breakthrough by developing the 3-D structure of proteins from inside the eye lens that control how cells communicate with each other, which could open the door to treating diseases such as cataracts, stroke and cancer. The PSU research team, led by chemistry professor Steve Reichow, used a multimillion-dollar microscope and a…
An interdisciplinary and international research group led by Dr. Volker Busskamp from the Center for Regenerative Therapies Dresden at the TU Dresden (CRTD) has decoded the regulatory impact on neuronal survival of a small non-coding RNA molecule, so-called miRNA, at the highest resolution to date.
Cell stress in combination with an altered microbiota in the colon drives tumour growth. Previously, it was assumed that this combination only contributes to inflammatory intestinal diseases.
A DNA-based analysis of blood cells soon after a stem cell transplant can predict likelihood of disease recurrence in patients with myelodysplastic syndrome (MDS), a group of cancerous disorders characterized by dysfunctional blood cells. Such a practice could help doctors identify patients at high risk of disease recurrence early after a transplant and help guide treatment decisions.
Macrophages are immune cells that are supposed to protect the body from infection by viruses and bacteria. Yet Zika virus preferentially infects these cells. Researchers at University of California San Diego School of Medicine have now unraveled how the virus shuts down the genes that make macrophages function as immune cells.
Cancer cells often have mutations in their DNA that can give scientists clues about how the cancer started or which treatment may be most effective. Finding these mutations can be difficult, but a new method may offer more complete, comprehensive results. A team of researchers has developed a new framework that can combine three existing methods of finding these large mutations - or structural…
Monash University’s Biomedicine Discovery Institute (BDI) researchers have identified a new mechanism used by Henipaviruses in infection, and potential new targets for antivirals to treat them. Their findings may also apply to other dangerous viruses.
The exchange of a single amino acid building block in a metabolic enzyme can lead to cancer. In addition, it can impair the immune system. It thus blocks the body’s immune response in the battle against the mutant molecule and also impedes immunotherapy against brain cancer. This finding opens new insights into cancer development and progression and it also suggests that rethinking antitumor…
Canadian researchers have found a promising way to stop tumour cells from multiplying. In disrupting the composition of ribosomes, the team from Université de Montréal (UdeM) discovered a direct molecular mechanism to stop cancer cells from proliferating, which is called senescence. Their results have been published in Nature Cell Biology. “Ribosomes are complex machines composed of both…
While treatments for HIV mean that the disease is no longer largely fatal, the world still lacks a true therapy that can eradicate the virus across a globally—and genetically different—population.
Dr. Thomas Hainmüller and Prof. Dr. Marlene Bartos of the Institute of Physiology of the University of Freiburg have established a new model to explain how the brain stores memories of tangible events. The model is based on an experiment that involved mice seeking a place where they received rewards in a virtual environment.
A new SLAS Discovery original research article available now for free ahead-of-print, researchers from the Genomics Institute of the Novartis Research Foundation (GNF) highlights a diversity of approaches that their automated high-throughput flow cytometry has enabled for phenotypic drug discovery. Flow cytometry is a very powerful tool that has been used for decades and allows for…
Menarini Silicon Biosystems announced that a new study has found that using circulating tumor cells (CTCs), a form of liquid biopsy, holds promise as a key tool for developing a staging system that can have a significant impact in the treatment of metastatic breast cancer (MBC). In this study, the largest CTCs pooled analysis study to date, researchers determined that the CTC count could be used…
Making tumour cells glow: Medical physicists at Martin Luther University Halle-Wittenberg (MLU) have developed a new method that can generate detailed three-dimensional images of the body's interior. This can be used to more closely investigate the development of cancer cells in the body. The research group presents its findings in "Communication Physics", a journal published by the…
Cell division is an intricately choreographed ballet of proteins and molecules that divide the cell. During mitosis, microtubule-organizing centers (MTOCs) assemble the spindle fibers that separate the copying chromosomes of DNA. While scientists are familiar with MTOCs’ existence and the role they play in cell division, their actual physical structure remains poorly understood. Shruthi…
Mutations in the p63 protein lead to a number of disorders, but none is as severe as the AEC syndrome. Scientists at Goethe University Frankfurt in collaboration with a research group from the University of Naples Federico II have now discovered that this syndrome resembles diseases such as Alzheimer’s, Parkinson’s or ALS more closely than it does other p63-based syndromes. Their results,…
