Renal gluconeogenesis: a key metabolic hub in health and kidney disease.
Review in Nephrology, dialysis, transplantation : official publication of the European Dialysis and Transplant Association - European Renal Association, 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
Gluconeogenesis, responsible for maintaining systemic glucose availability during fasting, has long been thought to be a process mainly performed by the liver. Over the past decades, physiological and molecular studies have established the kidney as a major site of endogenous glucose production. Renal gluconeogenesis occurs mainly in proximal tubular epithelial cells, where it integrates substrate utilization, hormonal signaling, and acid-base regulation to support systemic homeostasis. The kidney relies on distinct regulatory inputs and dynamically adapts gluconeogenic flux to nutritional state, metabolic acidosis, and interorgan metabolite exchange. As a highly metabolically active organ, it sustains the important energetic demands and differentiated state of proximal tubular cells through a high mitochondrial density. Renal gluconeogenesis is tightly coupled to ammoniagenesis and tricarboxylic acid cycle dynamics in addition to its contribution to glucose homeostasis, thus being a key determinant of mitochondrial integrity. Increasing evidence indicates that disruption of this metabolic program is a consistent feature of acute and chronic kidney disease, where suppression of gluconeogenesis accompanies epithelial dedifferentiation, mitochondrial dysfunction, and fibrotic remodeling. In this review, we synthesize current knowledge on the regulation and function of renal gluconeogenesis and discuss its emerging role as a central determinant of mitochondrial integrity, tubular resilience, and kidney disease progression.
