Comparative Transcriptome Analysis Reveals the Effects of a High-Protein Diet on Silkworm Midgut.
Article in Insects, 2025. 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
The silkworm is a species within the order Lepidoptera and an economic insect. The nutrients are obtained from the leaf and utilized by the silkworm larvae for body growth, development, and cocoon formation. Protein plays a significant functional role in the diet of silkworms. To investigate the impact of the high-protein diet (HPD 6%) on silkworm growth and development, transcriptomic analysis was conducted on the silkworm midgut, and 1724 differentially expressed genes (DEGs) were identified, comprising 803 up-regulated genes and 921 down-regulated genes. The up-regulated genes exhibited the majority pathway of mitochondrial oxidative phosphorylation, ribosome, and ribosome biogenesis in eukaryotes. The down-regulated genes of DEGs were mostly annotated in ABC transporters, lysosome, endocytosis, and sphingolipid metabolism pathways. The comprehensive analysis of DEGs indicated that substantial modifications were observed in various pathways associated with crucial biological processes. HPD 6% decreased oxidative stress and increased mitochondrial activity, ribosomal activity, and DNA repair capacity. Additionally, the ATP levels were increased in the midgut, malpighian tubule, middle silk gland, and posterior silk gland of the HPD 6% group. Moreover, the activities of SOD and NADH were enhanced in the midgut of the HPD 6% group. Our findings provide valuable insights into the wide-ranging effects of an HPD treatment in insects such as silkworms.
