Vinegar-processed frankincense extracts alleviate colorectal cancer by butyric acid mediating M1 tumor-associated macrophage pyroptosis.

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
backgroundOlibanum (RF), a traditional Chinese medicinal resin, shows efficacy in colorectal cancer (CRC) treatment. Its vinegar-processed form (PF) is clinically recognized for enhanced therapeutic effects, with prior mechanistic studies focusing on lipophilic components like boswellic acids. Yet, the regulatory mechanisms of PF's aqueous extracts remain unclear.
methodsThe aqueous extracts of RF and PF were characterized and compared through transmission electron microscopy (TEM), nanoparticle analysis, and protein profiling. The accumulation of these fractions in feces was confirmed using DiR dye labeling. A mouse CRC model was employed to evaluate and compare the therapeutic effects of RF and PF. The composition of butyric acid-producing microbiota was analyzed using 16S rRNA gene sequencing and metagenomics. Butyric acid levels were quantified using ultra-high-performance liquid chromatography coupled with triple quadrupole mass spectrometry (UHPLC-TQ-MS). Macrophage phenotypes were assessed via flow cytometry, while mRNA and protein expression levels were determined through RT-qPCR and western blot analysis.
resultsPF aqueous extracts exhibited distinct morphology, particle size, and protein content and had a superior therapeutic effect in alleviating CRC compared to RF. Further analysis confirmed that both RF and PF accumulated in feces and modulated the butyric acid metabolism of gut microbiota. The increased levels of butyric acid contributed to CRC alleviation by promoting the polarization of M1 tumor-associated macrophages (TAMs) and suppressing the pyroptosis of M1 TAMs.
conclusionThe study confirmed that vinegar-processed frankincense enhances its therapeutic effect on CRC by modulating M1 tumor-associated macrophages, which may provide efficient treatment of CRC from the perspective of host-gut metabolic interactions.
