  • Therefore, it would be relevant to establish the effects of PnV on tumor development in vivo , considering the complex neoplastic microenvironment. (nature.com)
  • The venom was effective at impairing tumor development in murine xenogeneic model, activating the innate immune response and increasing tumor infiltrating macrophages. (nature.com)
  • For instance, matched antibody pairs for tumor markers are often used in cancer research to qualify analytes such as CEA, PSA, EGF, and DKK1. (marijuanaparty.fun)
  • The rabbits were immunized with the purified recombinant protein. (hindawi.com)
  • The precursor protein (pre-IL-33) was cleaved by caspase-1 into a mature 18-kDa protein (IL-33) in in vitro experiments using a recombinant protein [ 2 ]. (hindawi.com)
