Jorunnamycin A induces apoptosis in pancreatic ductal adenocarcinoma cells, spheroids, and patient-derived organoids by modulating KRAS-mediated survival pathways.

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 an aggressive malignancy with a poor prognosis, frequently driven by oncogenic KRAS mutations. Among these, KRAS G12D is the most prevalent, contributing to chemoresistance and limiting the efficacy of current therapeutic strategies. This study investigates the therapeutic potential of jorunnamycin A (JA), a bioactive compound derived from the marine sponge Xestospongia, in PDAC. Molecular docking analyses were performed to assess JA's binding affinity for various KRAS protein variants. The synergistic effects of JA in combination with standard chemotherapeutic agents were evaluated using the Bliss independence model in pancreatic cancer cell lines and patient-derived PDAC organoids harboring distinct KRAS mutations. Furthermore, western blot analysis was performed to examine the impact the molecular mechanisms underlying JA's anticancer activity. JA demonstrated potent anticancer activity against PDAC cells, irrespective of their KRAS mutation status. In silico molecular docking and protein suppression studies indicated a strong binding affinity between JA and KRAS G12D. Synergistic interactions between JA and various PDAC chemotherapeutic agents, including oxaliplatin, SN-38, paclitaxel, 5-fluorouracil, and gemcitabine, were observed using the Bliss independence model. Notably, co-treatment with JA at a 10-fold lower concentration significantly enhanced the cytotoxicity of oxaliplatin, reducing its IC
