Abstract Text The AGC kinase family is important cell proliferation and survival. Dysregulation of this family contributes to gastric cancer progression. Here, we evaluated the potential activity of AT13148, a first-in-class multi-AGC kinase inhibitor, against gastric cancer cells. Our results showed that AT13148 exerted potent cytotoxic and anti-proliferative activities against a panel human gastric cancer cell lines (HGC-27, AGS, SNU-601, N87 and MKN-28), possibly via inducing cancer cell apoptotic death. Apoptosis inhibition by the Caspase blockers dramatically attenuated AT13148-caused cytotoxicity against gastric cancer cells. Intriguingly, same AT13148 treatment was not cytotoxic/pro-apoptotic to the non-cancerous human gastric epithelial GEC-1 cells. At the signaling level, AT13148 treatment in gastric cancer cells dramatically suppressed activation of multiple AGC kinases, including Akt (at p-Thr-308), p70S6 kinase (p70S6K), glycogen synthase kinase 3β (GSK-3β) and p90 ribosomal S6 kinase (RSK). Our in vivo studies demonstrated that daily oral gavage of AT13148 at well-tolerated doses significantly inhibited HGC27 xenograft tumor growth in nude mice. AGC activity was also dramatically decreased in AT13148-administrated HGC27 tumors. Therefore, targeting AGC kinases by AT13148 demonstrates superior anti-gastric cancer activity both in vitro and in vivo. The preclinical results of this study support the progression of this molecule into future evaluation as a valuable anti-gastric cancer candidate.

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.
