Serpina3m, a gene with its function not comprehensively defined yet, seems to be involved in multiple biological processes. Its potential association with inflammation, apoptosis, and immune-related pathways is indicated by various studies [1,2]. Genetic models, especially mouse models, can be valuable in further exploring its functions.

In a study on kidney ischemia/reperfusion injury in mice, combined treatment of an erythropoietin-derived peptide and caspase-3 siRNA led to up-regulation of Serpina3m, which was associated with modulated apoptosis and inflammation, as well as immunity, injury, and microvascular homeostasis [2]. In an aging-and alcohol-associated acute pancreatitis mouse model, Serpina3m was among the top five differentially expressed genes (DEGs) upregulated in aging mice compared to young mice, suggesting its role in the heterogeneous inflammatory processes of aging-related AAP [1]. Additionally, in a study on Shen Lin Bai Zhu San n-butanol extract's effect on DSS-induced colitis in mice, Serpina3m was closely related to colitis and was restored by the extract, indicating its potential role in colitis-related biological functions [3].

In conclusion, Serpina3m appears to play important roles in inflammation, apoptosis, and immune-related processes as revealed through mouse-based research. Its involvement in diseases such as acute pancreatitis, kidney ischemia/reperfusion injury, and colitis provides insights into potential molecular mechanisms underlying these diseases, which may offer new directions for diagnosis and treatment.
