Synergistic effect of PAF inhibition and X-ray irradiation in non-small cell lung cancer cells.

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
purposeProliferating cell nuclear antigen-associated factor (PAF) is involved in cancer cell growth and associated with cell death induced by ultraviolet (UV) radiation. However, the contribution of PAF to radiotherapy sensitivity in non-small cell lung cancer (NSCLC) is unknown. The aim of this study was to investigate the relationship between PAF expression and radiotherapy response in NSCLC.
methodsAssociations between PAF expression and patient survival outcomes were evaluated using publicly available online gene expression datasets. RNA interference was performed to knockdown PAF expression in the NSCLC cells. The effects of PAF knockdown on cell proliferation, migration, apoptosis, DNA damage, and activation of MEK/ERK and Wnt/β-catenin signaling pathways following X‑ray irradiation were evaluated in vitro.
resultsPAF was found to be overexpressed in lung cancer tissues compared with normal samples, and elevated PAF expression was significantly correlated with inferior patient survival. In vitro, knockdown of PAF inhibited cell proliferation, cell apoptosis, and migration induced by X‑ray irradiation. Moreover, X‑ray-induced intracellular DNA strand damage was more obvious following PAF knockdown. Additionally, PAF knockdown inhibited activation of the MEK/ERK and Wnt/β-catenin signaling pathways in X‑ray-irradiated A549 cells.
conclusionThese data demonstrate that reduced expression of PAF enhances radiosensitivity in NSCLC cells. Mechanistically, inhibition of the MEK/ERK and Wnt/β-catenin signaling pathways caused by PAF interference may lead to impaired cell function and enhance sensitivity to X‑rays. Targeting PAF may therefore serve as a potential therapeutic strategy to increase the efficiency of radiotherapy in NSCLC patients, ultimately improving patient survival.
