Photodynamic Therapy for X-ray-Induced Radiation-Resistant Cancer Cells.
Article in Pharmaceutics, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Radiotherapy, in which X-rays are commonly used, is one of the most effective procedures for treating cancer. However, some cancer cells become resistant to radiation therapy, leading to poor prognosis. Therefore, a new therapeutic method is required to prevent cancer cells from acquiring radiation resistance. Photodynamic therapy (PDT) is a cancer treatment that uses photosensitizers, such as porphyrin compounds, and low-powered laser irradiation. We previously reported that reactive oxygen species (ROS) derived from mitochondria induce the expression of a porphyrin transporter (HCP1) and that laser irradiation enhances the cytotoxic effect. In addition, X-ray irradiation induces the production of mitochondrial ROS. Therefore, radioresistant cancer cells established with continuous X-ray irradiation would also overexpress ROS, and photodynamic therapy could be an effective therapeutic method. In this study, we established radioresistant cancer cells and examined the therapeutic effects and mechanisms with photodynamic therapy. We confirmed that X-ray-resistant cells showed overgeneration of mitochondrial ROS and elevated expression of HCP1, which led to the active accumulation of porphyrin and an increase in cytotoxicity with laser irradiation. Thus, photodynamic therapy is a promising treatment for X-ray-resistant cancers.
