Philanthropy-backed accelerator advances cancer therapies
(<i>Dartmouth College</i>) An initiative launched by Norris Cotton Cancer Center and the Magnuson Center for Entrepreneurship to bring new cancer treatments to patients more quickly makes its inaugural award announcment.


An antibody-drug combo to combat cancer
(<i>Tokyo Medical and Dental University</i>) Researchers at Tokyo Medical and Dental University (TMDU) have developed an ingenious therapeutic strategy against chronic myelomonocytic leukemia that links a cytotoxic drug payload to an antibody vector that targets the CD64 marker highly expressed by monocytes and monocytic progenitors. This selective antibody-drug conjugate spares other blood cell lineages thus avoiding the side-effects of conventional anti-cancer drugs such as anemia, infection or bleeding diatheses. Consequently, this drug-delivery tactic shows great promise against other monocyte-related diseases.


CNIO researchers explain the toxicity of USP7 inhibitors, under development for cancer treatment
(<i>Centro Nacional de Investigaciones Oncológicas (CNIO)</i>) The researchers have discovered that USP7 inhibitors -under development by several pharmaceutical companies for the treatment of cancer- trigger a premature activation of cell cycle proteins, leading to uncontrolled cancer cell division and death.* The paper rejects the premise that the therapeutic efficacy of these inhibitors is due to their effects on activating the tumor suppressor protein P53, as currently accepted by the international scientific community. These results extend the potential use of USP7 inhibitors to a wider range of patients.
