But sometimes, it takes more than scissors to do the job. Now, a collaborative international team has unveiled a new CRISPR-based tool that acts more like a shredder, able to wipe out long stretches of DNA in human…
Inside the body, disease and injury can leave behind quite the mess — a scattering of cellular debris, like bits of broken glass, rubber and steel left behind in a car accident. Inside the central nervous system (CNS), a region that includes the brain and spinal cord, it is the job of certain cells, called microglia, to clean up that cellular debris. Microglia have counterparts called…
For some cancers, initial treatment with chemotherapy brings positive, but only temporary, results: tumors shrink, but then rebound as the cancer becomes drug-resistant. This pattern of remission-resistance-relapse is particularly true for pancreatic cancer, an aggressive disease in which early success is often countered by eventual disease progression. To wit: The one-year relative survival rate…
Shahid Umar, PhD, researcher with The University of Kansas Cancer Center, has dedicated two decades of his scientific exploration to better grasp the connection between colon cancer and the human microbiome.

The fates of immune cells can be decided at the initial division of a cell. Researchers at St. Jude Children’s Research Hospital have discovered that the production of daughter cells with different roles in the immune system is driven by the lopsided distribution of the signaling protein c-Myc. Nudging c-Myc in one direction or the other could make vaccines more effective or advance…
How do neurons become neurons? They all begin as stem cells, undifferentiated and with the potential to become any cell in the body. Until now, however, exactly how that happens has been somewhat of a scientific mystery. New research conducted by UC Santa Barbara neuroscientists has deciphered some of the earliest changes that occur before stems cells transform into neurons and other cell types.
Bioengineers and physicians at the University of California, San Diego have developed a potential new therapy for critical limb ischemia, a condition that causes extremely poor circulation in the limbs and leads to an estimated 230,000 amputations every year in North America and Europe alone to prevent the spread of infection and tissue death. The new therapy could prevent or limit amputations…
Scientists at the German Cancer Research Center (DKFZ) and the Stem Cell Institute HI-STEM in Heidelberg have discovered the reason why some pancreatic tumors are so resistant to treatment.
