1 Exosomal transfer of p-STAT3 promotes acquired 5-FU resistance in colorectal cancer cells. Fluorouracil signal transducer and activator of transcription 3 Homo sapiens
2 Xenograft models were established to determine whether exosomal p-STAT3 can induce 5-FU resistance in vivo. Fluorouracil signal transducer and activator of transcription 3 Homo sapiens
3 Inhibition of p-STAT3 re-sensitized RKO/P cells to 5-FU via caspase cascade. Fluorouracil signal transducer and activator of transcription 3 Homo sapiens
4 Furthermore, p-STAT3 packaged by exosomes from RKO/R cells increased resistance of tumor cells to 5-FU in vivo. Fluorouracil signal transducer and activator of transcription 3 Homo sapiens
5 CONCLUSIONS: Our results reveal a novel mechanism by which p-STAT3-containing exosomes contribute to acquired 5-FU resistance in CRC. Fluorouracil signal transducer and activator of transcription 3 Homo sapiens
