Researchers have discovered four new possible treatment targets for hard-to-treat cancers like osteosarcoma (a bone cancer), glioblastoma (a fast-growing brain tumor), and rare pancreatic tumors. These cancers often survive by using a backup system to protect their DNA called the ALT pathway (short for Alternative Lengthening of Telomeres). This system helps cancer cells keep dividing and growing, even when most treatments stop working.
To find these weak spots, scientists developed a new tool called BLOCK-ID, which acts like a microscope for cancer’s stress points. When cancer cells try to copy their DNA and make new cells, things can go wrong—this is called replication stress. BLOCK-ID lets researchers see which proteins rush in to help the cancer survive during this stress. One of the newly discovered proteins, TRIM24, along with three others, may be helping these tough cancers grow. Blocking them could shut down the cancer’s defenses.
More research is underway to test whether these new targets can lead to real treatments. For patients with aggressive or rare cancers, this offers new hope for future therapies that go after cancer at its core. (Source: Winship Cancer Institute at Emory University)
