We aimed to evaluate the mediators of the PI3K\/Akt and MAPK\/ERK signaling pathways in the kidney of db\/db mice, a model of type 2 diabetes, treated by the SGLT2 inhibitor empagliflozin, the DPP4 inhibitor linagliptin, and metformin. Eight-week-old male db\/db mice were randomly assigned to treatment by these agents or vehicle for 8 weeks. Age-matched db\/+ mice acted as controls. AMPK\u03b11 and PI3Kp110\u03b2 were evaluated in the renal cortex and medulla by Western Blot. Phosphorylated forms of principal molecules involved in the PI3K\/Akt and MAPK\/ERK pathways were assessed by multiplex analysis. Db\/db mice had decreased PI3Kp110\u03b2, increased phospho-PTEN, HSP27 and MEK1 in the renal cortex and medulla, BAD in the renal cortex and decreased phospho-rpS6 in the renal medulla. Empagliflozin prevented the changes in the levels of cortical PI3Kp110\u03b2, phospho-MEK1, and medullar phospho-PTEN. Linagliptin restored PI3Kp110\u03b2 levels. Both agents further decreased medullar phospho-rpS6. Metformin upregulated cortical AMPK\u03b11, medullar PI3Kp110\u03b2, phospho-GSK-3\u03b1\/\u03b2 and MEK1, and increased phospho-HSP27 in the renal cortex and medulla. The data may provide further explanation of the mechanism underlying the development of diabetic kidney disease, as well as the renal protective effect of anti-diabetic agents.<\/jats:p>","DOI":"10.3390\/ijms27146483","type":"journal-article","created":{"date-parts":[[2026,7,21]],"date-time":"2026-07-21T15:17:52Z","timestamp":1784647072000},"page":"6483","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Empagliflozin, Linagliptin, and Metformin Differentially Affect Renal PI3K\/Akt and MAPK\/ERK Signaling Pathways in db\/db Diabetic Mice"],"prefix":"10.3390","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3502-5892","authenticated-orcid":false,"given":"Anton I.","family":"Korbut","sequence":"first","affiliation":[{"name":"Research Institute of Clinical and Experimental Lymphology\u2014Branch of the Institute of Cytology and Genetics, Siberian Branch of Russian Academy of Sciences (RICEL\u2014Branch of IC&G SB RAS), Novosibirsk 630117, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elizaveta A.","family":"Ananishnikova","sequence":"additional","affiliation":[{"name":"Research Institute of Clinical and Experimental Lymphology\u2014Branch of the Institute of Cytology and Genetics, Siberian Branch of Russian Academy of Sciences (RICEL\u2014Branch of IC&G SB RAS), Novosibirsk 630117, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nikolai B.","family":"Orlov","sequence":"additional","affiliation":[{"name":"Research Institute of Clinical and Experimental Lymphology\u2014Branch of the Institute of Cytology and Genetics, Siberian Branch of Russian Academy of Sciences (RICEL\u2014Branch of IC&G SB RAS), Novosibirsk 630117, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4507-093X","authenticated-orcid":false,"given":"Nataliya P.","family":"Bgatova","sequence":"additional","affiliation":[{"name":"Research Institute of Clinical and Experimental Lymphology\u2014Branch of the Institute of Cytology and Genetics, Siberian Branch of Russian Academy of Sciences (RICEL\u2014Branch of IC&G SB RAS), Novosibirsk 630117, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0665-1723","authenticated-orcid":false,"given":"Natalia A.","family":"Muraleva","sequence":"additional","affiliation":[{"name":"Institute of Cytology and Genetics, Siberian Branch of Russian Academy of Sciences (IC&G SB RAS); Novosibirsk 630090, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Evgenii L.","family":"Zavyalov","sequence":"additional","affiliation":[{"name":"Institute of Cytology and Genetics, Siberian Branch of Russian Academy of Sciences (IC&G SB RAS); Novosibirsk 630090, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vladimir I.","family":"Konenkov","sequence":"additional","affiliation":[{"name":"Research Institute of Clinical and Experimental Lymphology\u2014Branch of the Institute of Cytology and Genetics, Siberian Branch of Russian Academy of Sciences (RICEL\u2014Branch of IC&G SB RAS), Novosibirsk 630117, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vadim V.","family":"Klimontov","sequence":"additional","affiliation":[{"name":"Research Institute of Clinical and Experimental Lymphology\u2014Branch of the Institute of Cytology and Genetics, Siberian Branch of Russian Academy of Sciences (RICEL\u2014Branch of IC&G SB RAS), Novosibirsk 630117, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"113","DOI":"10.1159\/000534071","article-title":"Disease Burden and Epidemiological Trends of Chronic Kidney Disease at the Global, Regional, National Levels from 1990 to 2019","volume":"148","author":"Ying","year":"2024","journal-title":"Nephron"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"281","DOI":"10.1038\/s41581-023-00694-0","article-title":"Regulated Cell Death Pathways in Kidney Disease","volume":"19","author":"Sanz","year":"2023","journal-title":"Nat.
