Cancer vaccines self-sabotage, channel immune attack to injection site

  UT MD Anderson scientists find common vaccine ingredient diverts T cells from tumors HOUSTON – Cancer vaccines that attempt to stimulate an immune system assault fail because the killer T cells aimed at tumors instead find the vaccination site a more inviting target, scientists at The University of Texas MD Anderson Cancer Center report…

Emerging cancer drugs may drive bone tumors

February 12, 2013 By Julia Evangelou Strait Chang Yang, MD, PhD   Investigational cancer drugs, IAP antagonists, may increase the risk of tumors spreading to bone. Tumors often cause bone loss, but IAP antagonist treatment accelerates the problem. Cancer drugs should kill tumors, not encourage their spread. But new evidence suggests that an otherwise promising…

Pancreatic cancers use high fructose corn syrup (HFCS), common in the Western diet to fuel their growth

Contact: Kim Irwin kirwin@mednet.ucla.edu310-206-2805 University of California – Los Angeles Health Sciences Pancreatic cancers use the sugar fructose, very common in the Western diet, to activate a key cellular pathway that drives cell division, helping the cancer to grow more quickly, a study by researchers at UCLA’s Jonsson Comprehensive Cancer Center has found. Although it’s…
