Glutathione Redox Activity-An Adaptative Mechanism in Clear Cell Renal Cell Carcinoma.
Article in International journal of molecular sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Environmental, genetic, immunological and metabolic factors are involved in renal cell carcinoma development. Clear cell renal carcinoma (ccRCC) is the most frequent renal cancer, with a complex metabolic physiopathology. The present study focuses on the characterization of chemical changes in glutathione redox homeostasis induced by oxidative damage and their relevance to ccRCC. We developed a prospective, case-control study that included 92 subjects diagnosed with ccRCC by histopathological exam and 40 healthy subjects. In each subject, we evaluated the chemical changes in glutathione redox homeostasis, antioxidative capacity, nitrosative stress, carbonyl stress, inflammation (IL-12 family members, albumin), angiogenesis factors and apoptosis. Compared to the control, in ccRCC subjects, we detected high levels of oxidative/electrophile stress, of hypoxia, and of inflammatory- and angiogenesis-related factors and low levels of anti-inflammatory-, anti-oxidative- and apoptosis-related factors. In ccRCC, positive correlations between glutathione redox homeostasis members expression and electrophile metabolites levels, respectively, angiogenesis markers and inflammatory parameters detected. Negative relations with anti-inflammatory and antioxidant markers were assessed. Glutathione redox homeostasis was altered in ccRCC, functioning as an active redox mechanism, with an essential role in the development and progression of ccRCC.
