N-Acetyl Aspartic Acid (NAA) Attenuates Stemness and Epithelial-Mesenchymal Transition and Enhances Radio- and Chemo-Sensitivity in Pancreatic Ductal Adenocarcinoma.
Article in Cells, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Pancreatic ductal adenocarcinoma (PDAC) is characterized by poor clinical outcomes and limited responsiveness to conventional treatments. Beyond delayed diagnosis, its high mortality is linked to limited treatment choices and resistance to chemotherapy. Neoplastic cells characterized by stem-like features and epithelial-mesenchymal transition (EMT) activation are crucial drivers of drug resistance and metastatic progression. Consequently, targeting these cellular programs could represent a promising therapeutic strategy for PDAC. N-acetyl-L-aspartic acid (NAA) is an endogenous metabolite, mainly localized in the central nervous system, where it facilitates acetate storage for lipid metabolism. Previous studies established its antineoplastic effect in neuroblastoma, promoting a more differentiated phenotype of cancer cells. Here we investigated the effects of NAA on BxPC-3 pancreatic cancer cells using both 2D and 3D models. NAA treatment induced a dose-dependent reduction in cell proliferation and led to a significant downregulation of stemness-associated surface markers, with concomitant upregulation of E-cadherin. Furthermore, NAA significantly enhanced cellular radiosensitization with a reduction in caveolin-1 and increased efficacy of gemcitabine in PDAC cells. Collectively, these results confirmed the anticancer activity of NAA and provide a rationale for further investigation of its synergistic effects with radiotherapy to yield better PDAC treatments.
