Discovery of oral cancer biomarkers could save thousands of lives

Oral cancer is known for its high mortality rate in developing countries, but an international team of scientists hope its latest discovery will change that. Researchers from the University of Otago, New Zealand, and the Indian Statistical Institute (ISI), Kolkata, have discovered epigenetic markers that are distinctly different in oral cancer tissues compared to the adjacent healthy tissues in patients. […]

Cancers ‘change spots’ to avoid immunotherapy

Cancers can make themselves harder for new immunotherapies to see by ‘changing their spots’ — and switching off a key molecule on the surface of cells that is otherwise recognised by treatment. Researchers found that they could test samples from patients with bowel cancer to identify which were most likely to respond to immunotherapy by assessing molecular changes within miniature […]

Blocking epigenetic Swiss army knife may be a new strategy for treating colorectal cancer

A new study out today in Cancer Cell shows that blocking specific regions of a protein called UHRF1 switches on hundreds of cancer-fighting genes, impairing colorectal cancer cells’ ability to grow and spread throughout the body. “Colorectal cancers are a growing public health problem, particularly in young people who haven’t yet reached the recommended age for regular screening,” said Scott […]

Imaging technique finds differences between radiation-sensitive and resistant tumors: Pilot clinical trials begun

Researchers have started pilot clinical studies in head and neck cancer patients to determine if Raman spectroscopy, a noninvasive imaging technique, can effectively spare some patients of the toxic side effects of ineffective radiation therapy. Researchers at the University of Arkansas, Johns Hopkins University and the University of Arkansas for Medical Sciences (UAMS) used the imaging technique and discovered differences […]

Malignant bone marrow disease: New hope for MPN patients: Myeloproliferative neoplasms (MPNs) — a group of rare but malignant bone marrow disorders

MPNs are a group of rare, malignant diseases of the bone marrow involving the production of an excess of red blood cells, white blood cells and/or platelets. MPNs are chronic diseases with only 1 to 2 new cases diagnosed per 100,000 people every year. MPNs can affect people at any age, but they are most common among adults around 60 […]

Method to ‘turn off’ mutated melanoma: New study provides novel insights into the pathogenesis and treatment of NRAS mutant melanoma

Melanoma is the deadliest form of skin cancer and notorious for its resistance to conventional chemotherapy. Approximately 25 percent of melanoma is driven by oncogenic mutations in the NRAS gene, making it a very attractive therapeutic target. However, despite decades of research, no effective therapies targeting NRAS have been forthcoming. For the first time, an international group of researchers has […]

New hope for stem cell approach to treating diabetes: Insulin-producing cells more responsive to fluctuating glucose levels

Scientists working to develop more effective treatments for diabetes are turning to stem cells. Such cells can be transformed into cells that produce insulin, the hormone that controls blood sugar. But there’s a major challenge: the amount of insulin produced by theses cells is difficult to control. Now, by tweaking the recipe for coaxing human stem cells into insulin-secreting beta […]

Scientists create a renewable source of cancer-fighting T cells

A study by UCLA researchers is the first to demonstrate a technique for coaxing pluripotent stem cells — which can give rise to every cell type in the body and which can be grown indefinitely in the lab — into becoming mature T cells capable of killing tumor cells. The technique uses structures called artificial thymic organoids, which work by […]

An errant editing enzyme promotes tumor suppressor loss and leukemia propagation

Writing in the January 3 issue of Cancer Cell, researchers at University of California San Diego School of Medicine report that detection of “copy editing” by a stem cell enzyme called ADAR1, which is active in more than 20 tumor types, may provide a kind of molecular radar for early detection of malignancies and represent a new therapeutic target for […]

How sperm stem cells maintain their number

The steady production of sperm relies on the number of sperm stem cells in the testis remaining constant. Researchers including Asst. Prof. Yu Kitadate and Prof. Shosei Yoshida (developmental biologists at the National Institute for Basic Biology within the National Institutes of Natural Sciences in Japan) and Prof. Benjamin Simons (a theoretical physicist at the University of Cambridge in the […]
