  • 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"


  • 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.

BRAF V600E KRAS A146T KRAS A146V colorectal cancer resistant LGX818 + Cetuximab + BYL719 Preclinical - Cell culture Actionable In a preclinical study, colorectal cancer cells harboring BRAF V600E developed sustained activation of Mapk signaling and resistance to combination treatment consisting of Erbitux (cetuximab), Encorafenib (LGX818), and Alpelisib (BYL719) in culture, likely due to the acquisition of KRAS A146V and A146T secondary resistance mutations (PMID: 27312529). 27312529
