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.

TP53 inact mut breast cancer sensitive AMG 900 Preclinical Actionable In a preclinical study, breast cancer cell lines with TP53 loss of function mutations had more pronounced apoptosis after treatment with AMG 900 in culture (PMID: 24091768). 24091768
TP53 inact mut lung small cell carcinoma sensitive APR-246 Preclinical - Cell line xenograft Actionable In a preclinical study, APR-246 induced apoptosis in small-cell lung cancer (SCLC) cell lines and decreased tumor growth in SCLC cell line xenograft models harboring Tp53 inactivating mutations (PMID: 21415220). 21415220
TP53 inact mut ovarian carcinoma sensitive ReACp53 Preclinical Actionable In a preclinical study, ReACp53 induced cell death and decreased proliferation of ovarian carcinoma cells harboring TP53 mutations in culture, but did not effect viability of ovarian carcinoma cells with wild-type TP53 (PMID: 26748848). 26748848
TP53 inact mut ovarian cancer sensitive Cisplatin + LB-100 Preclinical Actionable In a preclinical study, LB100 treatment decreased PP2A activity and increased sensitivity to Platinol (cisplatin) in a cisplatin-resistant ovarian cancer cell line harboring a TP53 inactivating mutation in culture (PMID: 25376608). 25376608
TP53 inact mut chronic lymphocytic leukemia predicted - sensitive AZD6482 Preclinical Actionable In a preclinical study, AZD6482 induced cell death in TP53-deficient chronic lymphocytic leukemia cells in culture and inhibited tumor growth in xenograft models (PMID: 26563132). 26563132
