  • Publication number: 20220298511
    Abstract: The present disclosure discloses use of combined inhibition of LncRNA SAMMSON and BRAF kinase for delaying adaptive drug-resistance of melanoma. The present disclosure reveals that the RAF/MEK/ERK kinase can rapidly up-regulate the RNA level of LncRNA SAMMSON in BRAF-mutated melanoma cells. Knocking down the SAMMSON can significantly facilitate the BRAF kinase inhibitor vemurafenib-induced apoptosis and increase the sensitivity of the cells to vemurafenib.

  • Publication number: 20220275083
    Abstract: The present invention provides a bispecific epitope binding protein comprising an anti-4-1BB agonist antibody and a PD-1 protein or a fragment thereof that binds to PD-L1 with high affinity. The bispecific epitope binding protein simultaneously and independently binds to 4-1BB and PD-L1, which engage 4-1BB upregulated T cells, especially effector CD8+ T cells, with tumor cells expressing PD-L1. These interactions induce strong activation of the cytotoxic activity of anti-tumor effector CD8+ T cells by both blocking PD-1/PD-L1-mediated inhibitory signaling and activating 4-1BB-mediated costimulatory signaling in mouse models. This bispecific epitope binding protein has a much stronger oncolytic effect compared to each component alone.
