Discovery suggests better way to treat certain prostate cancers, lymphomas

Certain prostate cancers and lymphomas have a major genetic weakness that doctors can exploit to help save patients’ lives, researchers at the University of Virginia School of Medicine have discovered. The weakness makes the subset of cancers particularly vulnerable to chemotherapy and radiation therapy, suggesting that those approaches should be […]

How cells detect, mend DNA damage may improve chemotherapy

The busy world inside a cell is directed by its DNA blueprint. When the blueprints are altered, cells can sicken, die or become cancerous. To keep DNA in working order, cells have ways to detect and mend damaged DNA. Now, researchers at Washington University School of Medicine in St. Louis […]

Fighting cancer with cancer: 3-D cultured cells could drive precision therapy

Honeycomb-like arrays of tiny, lab-grown cancers could one day help doctors zero in on individualized treatments for ovarian cancer, an unpredictable disease that kills more than 14,000 women each year in the United States alone. A team of researchers has devised a process that can grow hundreds of cultured cell […]

Deadly Lung Cancers are Driven by Multiple Genetic Changes

A new UC San Francisco-led study challenges the dogma in oncology that most cancers are caused by one dominant “driver” mutation that can be treated in isolation with a single targeted drug. Instead, the new research finds one of the world’s most deadly forms of lung cancer is driven by […]

Gene shown to induce undifferentiated cells during tadpole tail regeneration

A group of researchers at the University of Tokyo found that a particular gene, interleukin-11, functions as a key factor in inducing and maintaining undifferentiated cells when tadpoles regenerate their tail. Some animal species have the remarkable ability to reconstruct lost appendages. The African clawed frog (Xenopus laevis) is one such […]

Recipe to make human blood-brain barrier

The blood-brain barrier is the brain’s gatekeeper. A nearly impenetrable shield of cells, it keeps toxins and other agents that may be in circulating blood from gaining access to and harming the brain. A critical anatomical structure, the barrier is the brain’s first and most comprehensive line of defense. But […]

How Chronic Inflammation Tips the Balance of Immune Cells to Promote Liver Cancer

Study explains success of some types of cancer immunotherapy, provides new targets for the development of additional immunotherapies. Chronic inflammation is known to drive many cancers, especially liver cancer. Researchers have long thought that’s because inflammation directly affects cancer cells, stimulating their division and protecting them from cell death. But […]

Can environmental toxins disrupt the biological 'clock'?

Can environmental toxins disrupt circadian rhythms – the biological “clock” whose disturbance is linked to chronic inflammation and a host of human disorders? Research showing a link between circadian disruption and plankton that have adapted to road salt pollution puts the question squarely on the table. “This research shows that […]

Rochester chemists find new means to “block” cancer cell growth

When we are still embryos, proteins of the so-called “hedgehog” signaling pathway stimulate our cells to develop into different organs. When we are adults, this pathway falls largely silent, except in certain tissues that constantly regenerate themselves, for example our skin, and the linings of our blood vessels and digestive […]
