The key enzyme PYCR1 in proline metabolism: a dual driver of cancer progression and fibrotic remodeling.
Review in Journal of enzyme inhibition and medicinal chemistry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
Pyrroline-5-Carboxylate Reductase 1 (PYCR1), a member of the PYCR family, is a key enzyme in the proline biosynthesis pathway. Notably, PYCR1 was originally identified via genetic disease research, linking its mutations to the occurrence of cutis laxa. PYCR1 contributes to the pathogenesis of malignancies and fibrotic diseases via mechanisms involving metabolic reprogramming, Extracellular Matrix (ECM) remodelling, and redox homeostasis maintenance. PYCR1 upregulation has been reported in multiple malignancies including Hepatocellular Carcinoma (HCC), Lung Cancer (LC), Breast Cancer (BC), Bladder Cancer (BlC), and Gastric Cancer (GC), where it has been shown to promote cancer proliferation, migration, and therapy resistance, correlating significantly with advanced cancer stages and poor prognosis. On the other hand, in fibrotic disorders, PYCR1-mediated proline metabolism has been linked to the progression of pulmonary, myocardial, and cutaneous fibroses. Notably, although PYCR1-targeted small-molecule inhibitors have demonstrated therapeutic potential in preclinical studies, their clinical translation is yet to be validated.
