Abstract Text Increased cell migration and invasion lead to cancer metastasis and are crucial to cancer prognosis. In this study, we explore whether FBXW7 plays any role in metastatic process. We show that depletion of FBXW7 induces epithelial-mesenchymal transition (EMT) in human colon cancer cells along with the increase in cell migration and invasion. Moreover, FBXW7 deficiency promotes the generation of colon cancer stem-like cells in tumor-sphere culture. mTOR inhibition by rapamycin suppresses FBXW7 loss-driven EMT, invasion and stemness. Our results define the FBXW7/mTOR axis as a novel EMT pathway that mediates cancer invasion.

Filtering

  • Case insensitive filtering will display rows if any text in any cell matches the filter term
  • Use simple literal full or partial string matches
  • Separate multiple filter terms with a space. Any order may be used (i. e. a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page. Filtering has no impact on query parameters.
  • Use quotes to match on a longer phrase with spaces (i.e. "mtor c1483f")

Sorting

  • Generally, the default sort order for tables is set to be first column ascending; however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column. Be sure to set ascending or descending order for a given column before moving on to the next column.
