Targeting MutT Homolog 1 (MTH1) for Breast Cancer Suppression by Using a Novel MTH1 Inhibitor MA-24 with Tumor-Selective Toxicity.

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
backgroundBreast cancer is a commonly diagnosed cancer worldwide. Human MutT homolog 1 (MTH1) is found to be elevated in breast tumors and cancer cells need MTH1 for survival. Pharmacological inhibition of MTH1 may be potentially beneficial in the treatment of breast cancer.
methodsMA-24 was screened by malachite green colorimetric assay for MTH1 inhibitors and the kinetic characteristics of MA-24 were assessed. The features of MA-24's binding with MTH1 were ascertained through molecular docking, and the cytotoxic activity of MA-24 was validated in vitro and in vivo. Target engagement assays, comet assay, and Western blot confirmed the intracellular target and mechanism of MA-24.
resultsMA-24 shows potent antitumor bioactivity both in vitro and in vivo. MA-24 competitively inhibited the MTH1 and further induced DNA strand breaks, leading to increased apoptosis of cancer cells depending on the upregulation of the cleaved-caspase 3-cleaved-PARP axis. In particular, MA-24 exhibited a powerful efficacy and safety in vivo (tumor growth inhibition rate: 61.8%).
conclusionsMA-24 possesses a broad spectrum of breast cancer cytotoxicity and offered valuable insights for overcoming the challenges of chemotherapy-related toxicity, which holds great potential for the further development MA-24 as an anti-cancer drug.
