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.

Drug Name Trade Name Synonyms Drug Classes Drug Description
Lapatinib Tykerb FMM EGFR Inhibitor (Pan) 42 HER2 (ERBB2) Antibody 29 Tykerb (lapatinib) reversibly inhibits ERBB2 (HER2) and EGFR, resulting in decreased downstream signaling and potentially leading to reduced tumor growth (PMID: 22477724). Tykerb (lapatinib) is FDA approved for ERBB2 (HER2)-positive breast cancer (FDA.gov).
Trastuzumab Herceptin Anti HER2 HER2 (ERBB2) Antibody 29 Herceptin (trastuzumab) is a monoclonal antibody, which binds ERBB2 (HER2) to induce tumor cellular cytotoxicity (PMID: 17611206). Herceptin (trastuzumab) is FDA approved for HER2-overexpressing breast cancer, gastric adenocarcinoma, and gastroesophageal junction adenocarcinoma (FDA.gov).
