HNF1A regulates oxaliplatin resistance in pancreatic cancer by targeting 53BP1.
Article in International journal of oncology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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.
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
DNA double‑strand break repair is critically involved in oxaliplatin resistance in pancreatic ductal adenocarcinoma (PDAC). Hepatocyte nuclear factor 1 homeobox A (HNF1A) has received increased attention regarding its role in cancer progression. The present study explored the role of HNF1A in oxaliplatin resistance in PDAC. The results revealed that HNF1A expression was negatively associated with oxaliplatin chemoresistance in PDAC tissues and cell lines. HNF1A inhibition promoted the proliferation, colony formation and stemness of PDAC cells, and suppressed their apoptosis. Furthermore, HNF1A inhibition switched nonhomologous end joining to homologous recombination, thereby enhancing genomic stability and oxaliplatin resistance. Mechanistically, HNF1A transcriptionally activates p53‑binding protein 1 (53BP1) expression by directly interacting with the 53BP1 promoter region. Upregulation of HNF1A and 53BP1 induced significant inhibition of PDAC growth and oxaliplatin resistance in patient‑derived PDAC xenograft models and orthotopic models. In conclusion, the findings of the present study suggested that HNF1A/53BP1 may be a promising PDAC therapeutic target for overcoming oxaliplatin resistance.
