Nutrient intake and renal cancer: molecular pathways and mechanistic insights into the protective role of dietary components.
Review in Frontiers in nutrition, 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
Renal cell carcinoma involves specialized metabolic transformations centered on proximal tubule biology, yet its interface with nutrient intake is frequently interpreted within a generalized oncological framework. This review contextualizes dietary influences within the kidney-specific physiological environment, emphasizing the role of renal filtration dynamics and oxygen-sensing mechanisms in shaping nutrient-tumor interactions. We discuss mechanistic and experimental evidence suggesting that dietary components-particularly fermentable fibers and plant-derived phytochemicals-may function as context-dependent biochemical modulators within the renal microenvironment. Special attention is given to short-chain fatty acids generated by gut microbial fermentation, which may act as distal modulators along the gut-kidney axis and influence metabolic and inflammatory signaling relevant to renal carcinogenesis. By relating circulating nutritional metabolites to proximal tubule metabolic sensitivity and VHL-HIF-dependent regulation, this review aims to bridge systemic nutritional metabolism with metabolic reprogramming characteristic of kidney cancer. Overall, this kidney-centric perspective reframes nutrition from a broad health factor to a context-dependent molecular modulator within renal metabolic pathways, specifically identifying nutritional signals as biochemical modulators-such as short-chain fatty acids-that directly interface with the oncogenic microenvironment through the VHL-HIF and mTOR circuits.
