Scientists from the German Cancer Research Center (DKFZ) and the Hebrew University in Jerusalem demonstrated in mice that intestinal bacteria reprogram DNA activity in cells of the gut mucosa and thus have a considerable impact on the development of the healthy gut.
Non-alcoholic fatty liver disease (NAFLD) is mostly diagnosed in overweight and obese people. However, severe forms of NAFLD can also be detected in rare genetic diseases such as lipodystrophy or in patients with HIV, putting them at a high risk for developing liver failure, diabetes and cardiovascular diseases. Norbert Stefan and colleagues have now detected a yet unknown cause of NAFLD in lean…
Artificial intelligence (AI) has the potential to improve efficiencies and precision in sleep medicine, resulting in more patient-centered care and better outcomes, according to a new position statement from the American Academy of Sleep Medicine. Published in the Journal of Clinical Sleep Medicine, the position statement was developed by the AASM’s Artificial Intelligence in Sleep Medicine…
Biomedical researchers in Munich have isolated immune cells from human tonsils obtained following routine surgery, and used them to analyze aspects of the immune response and test the effects of anti-inflammatory agents at the cellular level. Human tissues that have been surgically removed from patients are normally treated as waste, especially when they are derived from a ‘dispensable’ organ…
Cancer cachexia often occurs in cancer patients in an advanced state. This metabolic wasting syndrome leads to severely reduced muscle mass and fat tissue, which cannot be reversed by nutritional support. Furthermore, muscle regeneration is affected during cancer cachexia due to impaired muscle stem cell function. A problem that also occurs often in the aging process. Cancer cachexia is…
Researchers identified a group of small molecules that may open the door to developing new therapies for Duchenne muscular dystrophy (DMD), an as-yet-uncured disease that results in devastating muscle weakening and loss. The molecules tested by the team from the Perelman School of Medicine at the University of Pennsylvania eased repression of a specific gene, utrophin, in mouse muscle cells,…
There has been an increase in deaths and disability due to chronic respiratory (lung) diseases over the past three decades, finds an analysis of data from 195 countries published by The BMJ. The poorest regions of the world had the greatest disease burden. Ageing and risk factors including smoking, environmental pollution, and body weight also play a key role, say the researchers. Chronic…
A protein that helps colorectal cancer cells spread to other parts of the body could be an effective treatment target, researchers from Hokkaido University discovered. Colorectal cancer patients with an immune system-regulating protein called interleukin 6 (IL-6) are more likely to have recurring tumors that can also spread to the liver, according to research published in the journal Cancer…
An organic compound produced by the gut flora – the metabolite 4-Cresol – is considered to have protective effects against both type 1 and 2 diabetes, notably by stimulating the growth of the insulin-producing pancreatic beta cells. This is according to a new study led by Inserm researcher Dominique Gauguier at the Environmental Toxicology, Therapeutic Targets, Cell Signaling and Biomarkers…
Scientists have created one of the most detailed maps of breast cancer ever achieved, revealing how genetic changes shape the physical tumour landscape. An international team of scientists, brought together by a £20 million Grand Challenge award from Cancer Research UK, has developed intricate maps of breast tumour samples, with a resolution smaller than a single cell. These maps show how the…
Researchers from Karolinska Institutet, Örebro University and Aarhus University, Denmark, have published the largest study to date on the risk of colorectal cancer in Crohn's disease. The article is published in the journal The Lancet Gastroenterology Hepatology. Crohn's disease is a chronic inflammatory bowel disease (IBD). Several previous studies have reported an increased risk of colorectal…
A surprising discovery about a rare form of childhood brain cancer suggests a new treatment approach for that cancer – and potentially many others. Researchers at the University of Virginia School of Medicine have determined that the supposedly simple cancer, called medulloblastoma, forms an unexpectedly intricate network to drive its growth. Some tumor cells actually turn into another type of…
Research into the novel Wuhan seafood market pneumonia virus, the deadly "coronavirus" that has forced the Chinese government to quarantine more than 50 million people in the country's dense industrial heartland, will be facilitated by the UC Santa Cruz Genomics Institute. The Genomics Institute's Genome Browser team has posted the complete biomolecular code of the virus for researchers…
Scientists at the University of Bologna have conducted the largest analysis of coronavirus 2019-nCoV genomes sequenced so far. This analysis confirms that the virus originates in bats and shows a low variability: the virus heterogeneity is low. At the same time, researchers identified a hyper-variable genomic hotspot in the proteins of the virus responsible for the existence of two virus…
Scientists suggest a new strategy that uses induced pluripotent stem cells (iPSCs) to regulate immune reaction to transplanted tissues. The team, led by Professor Ken-ichiro Seino of Hokkaido University’s Institute for Genetic Medicine, found that thymic epithelium cells derived from mouse induced pluripotent stem cells (iPSCs) can regulate immune response to skin grafts, extending their…
Eric Prossnitz, PhD, from the University of New Mexico Health Services and his team hope to help 93 million obese Americans fight their fat. In a paper published in Science Translational Medicine, they reported that G-1, a cancer-fighting compound they discovered some years ago, reduces fat in obese mice. Although G-1 is currently in phase 1 clinical trials for cancer, Prossnitz and his team are…
The situation is extraordinary: there have only ever been four declarations of public health emergencies of international concern in the past and now there are two at the same time. Whilst the risks associated with the novel coronavirus are still unclear, people in the Democratic Republic of the Congo are still battling with an outbreak of the deadly Ebola virus which has been ongoing since 2018…
The novel coronavirus that recently originated in Wuhan, China has grabbed headlines and caused concern among public health officials around the world. Two infectious disease experts share their insights on the novel coronavirus epidemic.
Researchers discover a novel checkpoint in immune cells with the potential to treat the cancer cell microenvironment. The recognition of bacterial infections or foreign substances is mediated and controlled by the human immune system. This innate and adaptive immune system comprises the most important metabolic and cellulare processes to fight against infections and other diseases. Paradoxically,…
A team of researchers from Osaka University, Kyoto Prefectural University of Medicine, and Toppan Printing Co., Ltd. succeeded in reconstructing adipose tissue balls (“mini-breasts”) with a functional vascular network using patient-derived cells, achieving a high graft survival rate in small animal models.

In their quest to find new and better methods to make cancer cells more susceptible to treatment, Karin Lindkvist and her research group at Lund University in Sweden are looking into the world of molecules, using the X-rays at the MAX IV laboratory. The researchers believe that limiting the cells' access to sugar will make cancer cells more sensitive to treatment. Many of the cancer treatments…
T cells play a huge role in our immune system's fight against modified cells in the body that can develop into cancer. Phagocytes and B cells identify changes in these cells and activate the T cells, which then start a full-blown program of destruction. This functions well in many cases – unless the cancer cells mutate and develop a kind of camouflage that let them escape the immune system…
