Core Tip

Core Tip: This study revealed that BRAFV600E mutant colorectal cancer (CRC) cells could lead to more angiogenesis and lymphoangiogenesis in the microenvironment by releasing exosomal long noncoding RNAs, inducing the formation of an immunosuppressive microenvironment. Our findings provide a hypothesis for finding new therapeutic strategies for BRAFV600E mutant CRC.
