Multi-omics analysis reveals diapause-associated lipid remodeling in the fat body of Colorado potato beetle.
Article in BMC biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundThe Colorado potato beetle, Leptinotarsa decemlineata (Coleoptera: Chrysomelidae), is a major pest of potato that undergoes diapause (hibernation) to survive harsh winter conditions. Lipid metabolism plays a crucial role in diapause preparation and maintenance. However, the specific changes in lipid composition and their molecular regulation remain unclear. This study integrates lipidomics, transcriptomics, and proteomics to investigate diapause-associated metabolic shifts in the fat body of L. decemlineata.
resultsWe identified significant increases in monounsaturated (e.g., oleic acid) and polyunsaturated (e.g., linoleic acid) fatty acids, as well as phosphatidylethanolamines (membrane lipids) enriched in unsaturated fatty acids during diapause. Transcriptomic analysis revealed the differential expression of genes related to energy metabolism and lipid processing, while qualitative proteomics identified some calcium-associated protein isoforms (regucalcin-like and annexin B9-like) that are uniquely present in diapause. Correlation analysis suggested that specific transcripts, such as carboxyl ester lipase, are associated with the regulation of key lipid molecules, including oleic acid and linoleic acid, during diapause. These findings advance our understanding of lipid regulation during diapause and highlight potential molecular targets for disrupting overwintering strategies, which could inform novel pest control approaches.
conclusionsDiapause in the Colorado potato beetle is associated with changes in lipid composition in the fat body, which is mediated through changes at the transcriptome and proteome levels.
