At the end of these procedures, the mice were sacrificed, and the serum levels of adrenocorticotropic hormone (ACTH), corticosterone (CORT), ghrelin, and leptin were determined by ELISA, and the weight of the adrenal glands was measured.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Findings<\/jats:title>\n                    <jats:p>The results showed that there were significant differences in body weight, body temperature, anxiety\u2010related behaviors, pain latency, and hormonal parameters between the OTC group and the IVC group. Compared to OTC, IVC had lower levels of leptin, especially under stress conditions, where a significant interaction between housing and stress was observed, and higher levels of ghrelin, ACTH, and CORT. IVC group also had increased body weight, adrenal gland weight, and body temperature. In the hot\u2010plate test, the IVC group showed increased latency of hind limb responses compared to the OTC group, but not in the tail\u2010flick test. IVC group exhibited more anxiety\u2010related behaviors in the OFT, while no differences were observed in the EPM.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>According to the results of this study, housing mice in IVCs appears to compromise welfare, altering behavioral, hormonal, and pain responses. This suggests that the IVC system can induce physiological and behavioral stress, potentially acting as a systemic confounding factor in mouse research.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/brb3.70601","type":"journal-article","created":{"date-parts":[[2025,5,30]],"date-time":"2025-05-30T06:45:11Z","timestamp":1748587511000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["How Do Individually Ventilated Cages Affect the Welfare of Male BALB\/c Mice?
