Abstract 5819: Src inhibitor suppresses rab11 mediated collective cell migration in colon cancer cells

Abstract

Abstract Collective cell migration has been demonstrated the importance in cancer metastasis. Instead of single cell migration, collective cell migration requires E-cadherin for the cohort cell migration. Rab11 the recycling vesicle protein plays the key role in E-cadherin dynamics and mediates collective cell migration. In this study, Src was hypothesized to regulate Rab11 mediated collective cell migration. Our results demonstrated Src inhibitor Dasatinib has less toxicity in HT-29 colon cancer cells, instead, the cell morphology was turned aggregated. The immunofluorescence image also showed E-cadherin polarity was lost after Dasatinib treatment and increased the potential of cell-cell contact inhibition. In transwell assay, Rab11 was found colocalized with E-cadherin in collective migrated cells. Dasatinib treatment can suppress collective cell migration and decrease the interaction of Rab11 and E-cadherin. This study demonstrated the important role of Src in Rab11 mediated collective cell migration through E-cadherin dynamics in colon cancer.
