Abstract Text Palliative treatment options for human cholangiocarcinoma (CCC) are quite limited and new therapeutic strategies are of utmost need. c-MET has been shown to be deregulated in many cancers, but the role of c-MET in the carcinogenesis of CCC remains unclear. The main purpose of this study is to evaluate the expression and also to investigate the role of c-MET and its effective inhibition for the treatment of CCC. In this study we investigated the effects of LY2801653, a small-molecule inhibitor with potent activity against MET kinase, in human CCC cell lines and in vivo using a xenograft mouse model. We have investigated the role of c-MET and its inhibitory effects on migration, invasion, colony formation, MET downstream targets, and CCC tumor growth. We also analyzed the role of apoptosis and senescence as well as the influence of hypoxia in this context. c-MET and p-MET were expressed in 72% and 12.5% of human CCC tissues and in TFK-1, SZ-1 cell lines. MET inhibition was achieved by blocking phosphorylation of MET with LY2801653 and subsequent down regulation of c-MET downstream targets. Treatment showed in a xenograft model potent anti-tumor activity. LY2801653 is an effective inhibitor and suppress the proliferation of CCC cells as well as the growth of xenograft tumors. Therefore, inhibition of c-MET could be a possible alternative approach for the treatment of human CCC. © 2016 Wiley Periodicals, Inc.

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.
