遺伝子研究の概要
Sat1, also known as spermidine/spermine N1-acetyltransferase 1, is a rate-limiting enzyme in polyamine catabolism. It is critically involved in converting spermidine and spermine back to putrescine. The gene participates in polyamine metabolism and is associated with pathways like ferroptosis, which is a form of regulated cell death. Understanding Sat1 is crucial as it impacts various biological processes and disease conditions [1,2,3,4,7,9].
In several disease models, the role of Sat1 has been revealed. In triple-negative breast cancer, high SAT1 expression is associated with poor prognoses, and SAT1 knockdown inhibits cell proliferation and migration, suggesting it drives tumor progression through the SAT1/YBX1/mTOR axis [5]. In an osteoporosis murine model, osteoclasts express a high level of SAT1 during osteoclastogenesis, and targeting SAT1 with Berenil promotes osteoclast apoptosis, reversing bone loss [6]. In X-linked childhood-onset systemic lupus erythematosus, loss-of-function variants in SAT1 were identified in affected families, and Sat1 p.Glu92Leufs*6 KI mice spontaneously developed lupus-like symptoms, highlighting the pathogenic role of dysregulated polyamine catabolism [8].
In conclusion, Sat1 plays essential roles in polyamine metabolism and is implicated in multiple disease conditions such as cancer, osteoporosis, and lupus. Gene-knockout and knock-in mouse models have been instrumental in uncovering its functions in these diseases, providing potential therapeutic targets for treatment.
