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

backgroundPancreatic cancer (PC) and colorectal cancer (CRC) are among the most lethal malignancies, with growing evidence pointing to the gut microbiota's role in their progression. This study aimed to explore the anticancer potential of two microbiota-derived postbiotics, N-acetylcysteine (NAC) and tetrahydro β-carboline carboxylic acid (THC), in targeting some hallmark traits of PC and CRC, both as standalone agents and in combination with standard chemotherapeutics (gemcitabine for PC and 5-fluorouracil (5-FU) for CRC).

methodsCell viability assays and IC

resultsHere, we found that NAC selectively reduced the viability of PC cells BxPC-3 without triggering apoptosis, while effectively inducing apoptosis in PC cells Panc-1 and in CRC cell lines. THC exhibited stronger anticancer activity, inhibiting proliferation and promoting apoptosis in all tested PC and CRC cells, even at lower concentrations. Combination treatments yielded promising enhancement effects. NAC enhanced the cytotoxicity of gemcitabine in Panc-1 cells through increased apoptosis. NAC, when combined with 5-FU, also increased apoptosis of CRC cells. THC further potentiated gemcitabine's impact on Panc-1 cells by increasing apoptosis and by inducing cell cycle changes in BxPC-3. In the CRC model, THC co-treatment with 5-FU reduced cell viability and increased apoptosis in all cells.

conclusionsThese findings provide preliminary in vitro evidence supporting the potential of integrating microbiota-derived postbiotics with conventional chemotherapy both in PC and CRC.
