Abstract Text Focal adhesion kinase (FAK) increasingly has been implicated in cancer growth and progression. 1,2,4,5-Benzenetetraamine tetrahydrochloride (Y15) is a small molecule FAK inhibitor that blocks the Y397 autophosphorylation site. FAK inhibitor, Y15 decreased Y397 FAK in different colon cancer cells lines in a dose-dependent manner. In addition, Y15 decreased phosphorylated Src in SW480 and SW620 cells. Y15 decreased cell viability, increased detachment, and increased apoptosis in SW480 and SW620 cells in vitro. Combination of FAK inhibitor Y15 and Src inhibitor PP2 decreased colon cancer cell viability more effectively than each agent alone. In addition, when combined with 5-FU, oxaliplatin or 5-FU and oxaliplatin, colon cancer viability was decreased further, demonstrating that dual and triple therapy synergistically inhibits cell viability. In vivo, Y15 decreased subcutaneous SW620 tumor growth by 28%. Combination of oral Y15 with 5-FU/or oxaliplatin decreased tumor growth by 48% more effectively than each inhibitor alone. Finally, tumors treated with Y15 expressed less Y397 phosphorylation, Src phosphorylation and had greater apoptosis than controls. Thus, the small molecule FAK inhibitor, Y15, inhibits cell growth in vitro and in vivo and enhances the efficacy of chemotherapy, demonstrating that it can be an effective therapeutic inhibitor for treating colon cancer.

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.
