The RNA binding protein hnRNPK protects against adriamycin-induced podocyte injury.
Article in Annals of translational medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundPodocytes maintain the integrity of the glomerular filtration barrier and serve as the final barrier to protein loss. Podocyte injury may induce severe apoptosis, which can result in serious kidney damage and disease. Therefore, it is necessary to explore how podocyte injury can be prevented and to thereby discover a feasible therapy for kidney disease. However, the mechanism of podocyte injury is still unclear.
methodsThe mRNA and protein expression levels of synaptopodin and nephrin in MPC5 podocytes with adriamycin (ADR)-induced injury were detected by quantitative real-time PCR and western blot. The expression levels of heterogeneous nucleotide protein K (hnRNPK), caspase-3, Bax, and Bcl-2 protein in cells and tissues were measured using western blot. Proliferation were measured in treated MPC5 podocytes by Cell Counting Kit-8 (CCK-8) assay, EdU assay, and apoptosis was measured by Hoechst 32258 staining. Mitochondrial membrane potential disruption, lactate dehydrogenase (LDH) leakage, and reactive oxygen species (ROS) generation were measured using JC-1 staining, an LDH reagent kit, and a ROS detection kit. Hematoxylin and eosin (HE) staining was used to observe histological changes in mouse tissues.
resultsSynaptopodin and nephrin were downregulated in ADR-treated podocytes. Overexpression of hnRNPK ameliorated the inhibitive effect of ADR treatment on podocyte proliferation and reduced its promotion of podocyte apoptosis. LDH leakage and ROS generation were increased in ADR-treated podocytes, but were reduced by hnRNPK treatment.
conclusionsADR-induced podocyte injury is ameliorated by hnRNPK both
