Drug resistance in pancreatic cancer: Scientists pinpoint major and minor signaling pathways that drive it

 


Cancer drug resistance is the devastating reason that treatments fail and cancers metastasize, spreading to distant sites seeding new resistant tumors elsewhere in the body.

Combating the problem has become the singular enterprise of some cancer research laboratories, which have been seeking the myriad causes of drug resistance and searching for methods to thwart them.

At the University of Virginia in Charlottesville, scientists who had been searching for elusive signaling pathways that underpin drug resistance in pancreatic ductal adenocarcinoma not only found them, but traced them to another molecular mechanism that insidiously sustains drug resistance.

As scientific sleuths, the team relied on information theory, a branch of applied mathematics, to aid their hunt for errant molecules that help drive drug resistance in cancer.

Pancreatic ductal adenocarcinoma is the most common form of the disease, affecting up to 90% of people diagnosed with the cancer, according to the U.S. National Institutes of Health.

The cancer is also extraordinarily difficult to treat because of its usually late-stage diagnosis and treatment obstacles stemming from drug resistance, which impact patients no matter where they are undergoing therapy around the globe.

Pausing” Cell Death Could Be the Key to Longevity

  Necrosis drives aging and disease by triggering damaging inflammation. Interrupting it may offer new treatments for chronic conditions and improve health in space travel. Necrosis, a form of uncontrolled cell death, may hold one of the most promising keys to altering the course of human aging, disease, and even space travel, according to a new study by researchers at UCL, the drug discovery company LinkGevity, and the  European Space Agency  (ESA). Challenging conventional thinking, the paper draws on evidence from cancer biology, regenerative medicine, kidney disease, and space health to argue that necrosis is not just a final stage of cell death, but a major driver of aging—and a potential target for intervention. Dr. Keith Siew, an author of the study from UCL Centre for Kidney & Bladder Health, said: “Nobody really likes talking about death, even cell death, which is perhaps why the physiology of death is so poorly understood. And in a way, necrosis is death. If...

Record-Shattering Molecule Stores Data at “Dark Side of the Moon” Temperatures

Image
  Researchers from The University of Manchester and The  Australian National University  (ANU) have developed a novel molecule capable of storing data at extremely low temperatures, comparable to the frigid conditions on the moon’s dark side at night. Their results, published in  Nature , point toward the potential for future data storage devices no larger than a postage stamp, yet capable of holding up to 100 times more information than today’s leading technologies. “The new single-molecule magnet developed by the research team can retain its magnetic memory up to 100 Kelvin, which is about minus 173 degrees  Celsius , or as cold as an evening on the moon,” co-lead author Professor Nicholas Chilton, from the ANU Research School of Chemistry, said. “This is a significant advancement from the previous record of 80 Kelvin, which is around minus 193 degrees Celsius. If perfected, these molecules could pack large amounts of information into tiny spaces. “Pink Floyd’...

Does cellular senescence hold secrets for healthier aging

Image
  Disease, injury, and other stress factors harm cells throughout our bodies. Ideally, the damaged cells are cleared by our immune systems through a process called apoptosis. But as we age, our bodies are no longer as effective at removing dysfunctional cells, and this can contribute to a weakened immune system and other less efficient biological processes. An increasing number of researchers are exploring whether learning to harness a cellular state known as senescence — during which damaged cells resist removal by apoptosis, linger, and harm neighboring normal cells — might hold the key to revitalizing aging tissues and increasing healthy, active years of life. Senescent cells are unique in that they eventually stop multiplying but don’t die off when they should. They instead remain and continue to release chemicals that can trigger inflammation. Like the one moldy piece of fruit that corrupts the entire bowl, a relatively small number of senescent cells can persist and spread in...
