Diseases disrupt the functioning of the nervous and reproductive systems and the gastrointestinal tract. The study aims to investigate the role of the Drosophila melanogaster swiss cheese gene, an ortholog of the human PNPLA6 gene, in gut function. We showed that the swiss cheese gene knockout leads to changes in the morphology of the midgut, disruption of the septate junction structure and the intestinal barrier permeability, and a decrease in the lipid droplet number in enterocytes. As a result of such disturbances, intestinal stem cells (ISCs) proliferation is activated, and the gut microbiome is altered. Ectopic expression of human PNPLA6 leads to the recovery of the intestinal barrier in the fly gut. The example of Drosophila demonstrates the important role of evolutionarily conserved (lyso)phospholipase in intestinal homeostasis.<\/jats:p>","DOI":"10.3390\/ijms262211085","type":"journal-article","created":{"date-parts":[[2025,11,17]],"date-time":"2025-11-17T10:24:58Z","timestamp":1763375098000},"page":"11085","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Swiss Cheese Gene Is Important for Intestinal Barrier, Microbiome, and Lipid Metabolism Regulation in Drosophila Gut"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9576-9482","authenticated-orcid":false,"given":"Ekaterina A.","family":"Ivanova","sequence":"first","affiliation":[{"name":"Petersburg Nuclear Physics Institute Named by B.P.
