Polyamine Metabolism Promotes the Progression of Thyroid Carcinoma by Regulating the Immune Phenotype of Tumor Associated Macrophages.

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
Polyamine metabolism is a key regulator of cellular proliferation and immune modulation, and its dysregulation is implicated in multiple carcinoma pathogenesis. Macrophages also greatly influence tumor progression by regulating the immune microenvironment. However, the role of polyamine metabolism in thyroid cancer macrophages remains understudied. This study explores the connection between polyamine metabolism and macrophages in thyroid cancer. Using the THCA dataset gene expression analysis and single-cell data, we identified macrophage subpopulations. We assessed immune scores, matrix scores, immune checkpoint scores, and immune cell types using Bulk-RNA data and the TIDE platform to predict immune checkpoint inhibitor responses. Clinical specimens validated our findings. Our results show a significant association between polyamine metabolism and the clinical and biological characteristics of thyroid cancer, including macrophage trajectory. Notably, macrophage subpopulations affected by polyamine metabolism have strong prognostic value, especially in immunotherapy patients. We found that changes in these subpopulations correlate with thyroid cancer development, and tumor tissue can regulate macrophage polyamine metabolism. This study provides new insights into how polyamine metabolism affects macrophages and the tumor microenvironment, influencing tumor growth and anti-tumor immune responses in thyroid cancer.
