Abstract Text Sequencing studies have revealed recurrent mutations in the RAS pathway in rhabdomyosarcoma (RMS). However, RAS effector pathways in RMS are poorly defined. Here, we report that coinhibition of NRAS or MEK plus PI3Kα triggers widespread apoptosis in NRAS-mutated RMS cells. Subtoxic concentrations of the MEK inhibitor MEK162 and the PI3Kα-specific inhibitor BYL719 synergized to trigger apoptosis in NRAS-mutated RMS cells in vitro and in vivoNRAS- or HRAS-mutated cell lines were more vulnerable to MEK162/BYL719 cotreatment than RAS wild-type cell lines, and MEK162/BYL719 cotreatment was more effective to trigger apoptosis in NRAS-mutated than RAS wild-type RMS tumors in vivo We identified BCL-2-modifying factor (BMF) as an inhibitory target of oncogenic NRAS, with either NRAS silencing or MEK inhibition upregulating BMF mRNA and protein levels, which BYL719 further increased. BMF silencing ablated MEK162/BYL719-induced apoptosis. Mechanistic investigations implicated a proapoptotic rebalancing of BCL-2 family members and suppression of cap-dependent translation in apoptotic sensitivity upon MEK162/BYL719 cotreatment. Our results offer a rationale for combining MEK- and PI3Kα-specific inhibitors in clinical treatment of RAS-mutated RMS.Significance: These findings offer a mechanistic rationale for combining MEK- and PI3Kα-specific inhibitors in the clinical treatment of RAS-mutated forms of often untreatable rhabdomyosarcomas.

Filtering

  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (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 a longer phrase which contains spaces "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.
