Abstract Text Pancreatic cancer is a deadliest type of malignancy and lacks effective intervention. We here report a potential strategy for treatment of this malignancy by the combination of arsenic trioxide (ATO) and BET bromodomain inhibitor JQ1. These two agents synergistically modulate multistages of autophagy and thus induce apoptosis effectively in pancreatic cancer cells. Our genomic and biochemical data have demonstrated that crosstalks between ER stress and autophagy play crucial roles during ATO-induced apoptosis, in which NRF2 may stand at the crossroad between cell death and survival. This has been further strengthened by our finding that NRF2 depletion renders insensitive cells into sensitive ones in regard to ATO treatment-caused cell death. The knockdown of NRF2 and the addition of JQ1 result in similar molecular/cellular effects in promoting effective ATO-induced apoptosis in cells that are insensitive to ATO treatment alone. Thus, the combination of ATO and JQ1 may represent a new treatment strategy for pancreatic cancer.

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.
