Cancer researchers have made great strides in developing targeted therapies that treat the specific genetic mutations underlying a patient's cancer. However, many of the most common cancer-causing genes are so central to cellular function throughout the body that they are essentially 'undruggable'. Now, researchers at UC San Francisco have found […]

Researchers at Oregon State University have taken an important step toward a more convenient, less expensive means of preserving mammalian cells for in vitro fertilization, species conservation, cell therapy and other purposes. The method is desiccation – removing water from cells – and shows promise as an alternative to cryopreservation […]

Hard to detect in its early stages, and hard to treat as it advances, lung cancer is the leading cause of cancer mortality around the world, with an estimated 1.6 million deaths each year. New treatments, however, are bettering the odds for people with non-small cell lung cancer (NSCLC), which […]

More than 400,000 Canadians aged 65 and over live with diagnosed dementia, including Alzheimer’s disease, which accounts for approximately 70 percent of cases. The cause of this degenerative brain disease is largely unknown and no effective treatment exists. The disease has a devastating effect on individuals and their families. To […]

The planarian flatworm Schmidtea mediterranea is an extraordinary animal. Even when cut into tiny pieces, each piece can regenerate back into a complete and perfectly proportioned miniature planarian. Key to this ability are fascinating adult stem cells, a single one of which can restore a complete worm. But how Schmidtea mediterranea achieves these feats […]

A team of researchers led by scientists in Vienna, Dresden and Heidelberg has decoded the entire genetic information of the Mexican salamander axolotl. The axolotl genome, which is the largest genome ever to be sequenced, will be a powerful tool to study the molecular basis for regrowing limbs and other […]

The oncogene RAS is the most frequently mutated gene of its type in human cancer. Active mutants are found in 60 to 90 percent of cases of pancreatic cancer, and a significant portion of colorectal and lung cancers. Among all RAS-driven cancers, the most frequently mutated gene is KRAS. Two […]

Working with mouse tissue, the research team discovered that fluid pressure felt by embryonic lungs helps control the rate of development of the organ. This pressure coordinates the contraction of the smooth muscles girding the airways, which in turn spurs the sprouting of new branches throughout the fledgling lung. The […]

As Isoplexis, the company co-founded by Yale’s Rong Fan and Sean Mackay ’14, prepares to take its production to the next level in 2018, two science news publications have honored the company for technology that tailors optimum treatments for cancer patients. The Scientist magazine named the company’s IsoCode chip and IsoLight platform, an all-in-one system that reads the individual […]

The most common form of breast cancer is oestrogen-receptor-positive, so called hormone-sensitive breast cancer. This means that the tumour needs the female hormone oestrogen to grow. Women who develop this kind of breast cancer have a remaining long-term risk of dying of the disease. It is also known that the […]

Turning off enzymes that are important for the survival of growing cells is a promising strategy to fight cancer. But to be able to shut down only one specific enzyme out of thousands in the body, drugs have to be tailored to exactly fit their target. This is particularly difficult […]

Researchers at Vanderbilt University Medical Center (VUMC) have demonstrated for the first time that it is possible to starve a tumor and stop its growth with a newly discovered small compound that blocks uptake of the vital nutrient glutamine. Their findings, reported in Nature Medicine, lay the groundwork for development of […]

Hematopoietic stem cells (HSCs) have long been regarded as the granddaddy of all blood cells. After we are born, these multipotent cells give rise to all our cell lineages: lymphoid, myeloid and erythroid cells. Hematologists have long focused on capturing HSCs’ emergence in the embryo, hoping to recreate the process […]
