유전자 연구 개요
St8sia1, also known as GD3 synthase, is a ganglioside synthesis enzyme. It is involved in the synthesis of GD2, a key molecule in the context of anti-GD2 antibody-based immunotherapies. Its functions are related to multiple signaling pathways, including Wnt/β-catenin, FAK/Akt/mTOR, and JAK/STAT, which are crucial for cell growth, survival, and metastasis [1,2,4].
In neuroblastoma, a forced adrenergic-to-mesenchymal transition leads to down-regulation of St8sia1, reducing GD2 expression and conferring resistance to anti-GD2 antibody. Pharmacologic inhibition of EZH2 can re-express St8sia1, restoring GD2 expression and sensitivity to the antibody [1].
In triple-negative breast cancer, increased St8sia1 levels are associated with chemoresistance, and its inhibition sensitizes the cancer cells to chemotherapy by suppressing Wnt/β-catenin and FAK/Akt/mTOR pathways [2].
In rectal adenocarcinoma, overexpression of St8sia1 inhibits tumor progression via TGF-β1 signaling and promotes the tumoricidal effects of CD8+ T cells [3].
In bladder cancer, St8sia1 overexpression attenuates cell proliferation, migration, and invasion by blocking the JAK/STAT signaling pathway [4].
In TNBC, St8sia1 is highly expressed, positively correlated with BCSC-associated genes, and its knockout blocks in vivo tumor growth and metastasis by activating the FAK-AKT-mTOR signaling pathway [5].
In mice, St8sia1-deficiency in gliomas leads to reduced disease severity, altering the tumor environment [6].
In conclusion, St8sia1 plays diverse roles in multiple cancer types, influencing tumor growth, metastasis, and response to therapies. Studies using gene-knockout models, especially in mice, have been instrumental in revealing these functions, highlighting St8sia1 as a potential therapeutic target in cancer treatment.
