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 one of the most aggressive malignancies of the digestive system, characterized by late diagnosis, resistance to conventional therapies, and poor survival outcomes. Therefore, the development of novel, effective, and targeted therapeutic strategies is urgently needed. This study aimed to evaluate the anticancer potential of Acinetobacter baumannii-derived outer membrane vesicles (OMVs) conjugated with Vaccinium myrtillus extract, a low-toxicity natural compound, against pancreatic cancer cells. For this purpose, V. myrtillus was conjugated with A. baumannii-derived OMVs, and the antimicrobial activity of the conjugate was assessed using disk diffusion, minimum inhibitory concentration, time-kill kinetics, and biofilm inhibition assays. The anticancer effects were investigated by treating PANC-1 pancreatic cancer cells and healthy fibroblast cells with OMVs (50 µg/mL) and increasing concentrations of V. myrtillus (5-250 µg/mL). After 24 h, cell viability and cytotoxicity (MTT, LDH), oxidative stress parameters (TAS, TOS, SOD, GR), PI3K/AKT/PTEN signaling pathway components, apoptotic markers (Annexin V/PI, BAX, Bcl-2, Caspase-8), and inflammatory cytokines (IL-1β, IL-10) were analyzed. The OMV-V. myrtillus conjugate (50 µg/mL OMV +250 µg/mL V. myrtillus) significantly reduced cell viability by approximately 60% through disruption of intracellular redox balance. Elevated oxidative stress triggered apoptotic signaling, approximately increased 50% LDH release, and enhanced inflammatory responses. Especially 50 µg/mL OMV +250 µg/mL V. myrtillus treatment group compared to the control group, which approximately increased to 1-fold IL-1β rate. Furthermore, the 50 µg/mL OMV +250 µg/mL V. myrtillus treatment group showed approximately a 0.75-fold increase in PTEN and BAX gene expression, accompanied by a correlated decrease in AKT and BCL-2 gene expression, compared to the control group. These results suggest that OMV-mediated delivery of V. myrtillus represents a promising synergistic therapeutic approach for treatment-resistant pancreatic cancer.
