1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Pancreatic cancer (PC) is a worldwide leading cause of cancer-related death. Despite recent progress using immunotherapy with checkpoint inhibitors or targeted agents in various solid tumors, these approaches have not been successful in PC. Therefore, there is an urgent unmet need for the development of novel therapeutics for these difficult-to-treat patients. We hypothesized that high-dose L-ascorbic acid (AA) could disrupt redox homeostasis and selectively inhibit the viability of PC cells harboring KRAS mutations; thus, we investigated the molecular mechanism of AA cytotoxicity in PC cell lines (Hs 700T, BxPC-3, HPAC, HPAF-II, PANC-1, SU.86.86, and Hs 766T) and patient-derived cells (PDCs; PR11-043T and PR11-077T)), identifying a subset of patients who may benefit from AA therapy and opening an avenue for further clinical development. In this preclinical study, we found that AA efficiently inhibited the growth of KRAS G12D-mutant PC cells. Mechanistically, this was due to selective glycolysis inhibition via GAPDH inactivation and DNA damage, in PC cell lines harboring KRAS G12D. We also showed that AA synergizes with the DNA-damaging agent AZD6738 in PC cells and AA induces an enhanced DNA damage response in BRCA mutant PC cells, as confirmed in PC PDCs having with KRAS G12D or BRCA1/2 mutation. This study showed the antitumor activity of AA in PC cells and PDCs, indicating that KRAS G12D identifies an attractive subset of PC cells for treatment using AA and novel agents targeting key molecules involved the DNA damaging pathway. In addition, DNA damage response (DDR)-defective cell subsets, including germline BRCA1/2 mutants, may be potential candidates for this novel approach, which provides new insights for future clinical development.
