In Mice, Eliminating Damaged Mitochondria Alleviates Chronic Inflammatory Disease

Inflammation is a balanced physiological response – the body needs it to eliminate invasive organisms and foreign irritants, but excessive inflammation can harm healthy cells, contributing to aging and chronic diseases. To help keep tabs on inflammation, immune cells employ a molecular machine called the NLRP3 inflammasome. NLRP3 is inactive […]

'Fingerprint database' could help scientists to identify new cancer culprits

Scientists from King's and Cambridge have developed a catalogue of DNA mutation ‘fingerprints’ that could help doctors pinpoint the environmental culprit responsible for a patient’s tumour – including showing some of the fingerprints left in lung tumours by specific chemicals found in tobacco smoke. Our DNA, the human genome, comprises […]

Cataracts and Amyloid Beta: Early Marker and New Drug Target?

I’ve just had cataract surgeries, so I wasn’t thrilled to find a new report in the Proceedings of the National Academy of Sciences comparing the protein glitch behind them to the one behind Alzheimer’s. Fortunately the similarity is only in how the proteins fold. The amyloid beta buildup of cataracts could be an early […]

Anti-inflammatory drugs ineffective for prevention of Alzheimer’s disease

Researchers have known for decades that inflammation accompanies Alzheimer’s disease (AD) brain lesions. Several early studies suggested that “super-aspirins” or Nonsteroidal anti-inflammatory drugs (NSAID) could help avoid the disease. However, after clinical trials showed that NSAIDs don’t help patients who already have AD symptoms, doctors wondered whether these drugs could […]

New resource expands use of lab technique to visualise DNA in cells

Researchers at Karolinska Institutet present a publicly available resource that can accelerate the use of so-called FISH techniques for studying how the genome is spatially organised in the cell nucleus. The new platform, which enables more cost-effective analyses for both research and diagnostic labs, is described in the scientific journal Nature […]

Turning patients’ own cells into cancer fighters

The next cancer therapy could be a patient’s own cells. Tactiva Therapeutics, a Buffalo-based immuno-oncology startup, is developing a personalized cancer treatment based on engineered immune cells derived from patients’ own cells. The company’s approach involves attaching proteins called receptors to these cells. The receptors target antigens present in cancer […]

Personalized medicine for children with cancer

This may help identify the cause of the cancer, so that the children can receive more precise treatment in the long term and avoid unnecessary side effects. Personalized medicine is now a reality for Danish children with cancer. If children can be prevented from dying from the disease, receive a […]

Blood-based screen for colon cancer shows promise

If caught early, nearly all cases of colon cancer are curable. Though this should make screening tests straightforward, colon cancer screening suffers from a paradoxical combination of low compliance rates and overdiagnosis. In a study published in the Proceedings of the National Academy of Sciences, University of Wisconsin–Madison scientists identified four blood-based fingerprints – […]

A New Role for Genetics in Cancer Therapy-Induced Cardiomyopathy

Recent advances in the development of cancer therapies have increased long-term survival and prognosis. However, the increased burden and prevalence of harmful side effects, including cardiomyopathy, have emerged alongside those therapeutic benefits. In particular, there have been increases in cancer therapy-induced cardiomyopathy (CCM) — a heart condition which may compromise […]

New tool helps find genetic culprits in cancer’s spread

The ability of cancer to establish itself in distant parts of the body — called metastasis — causes 90% of deaths from solid tumors. Metastasis is the result of complex genetic interactions that have proven difficult for scientists to study. Now Yale researchers have devised a way to identify some […]

A New Biological Aging Clock: Ribosomal DNA

Chronological aging is easy to track – birthdays. Biological aging can be obvious too – graying hair, sagging skin, and other inexorable signs of impending decrepitude. But measuring biological aging isn’t as easy as noting the passage of time. The best-studied measure of biological age is the shrinking of chromosome tips, or telomeres, […]
