表型提示
MGI:106011Homozygotes for a targeted allele are behaviorally normal with no signs of aberrant brain histology or demyelination. Homozygotes for a knock-out allele are behaviorally intact with normal nervous tissue morphology and sensitivity to Fas-mediated apoptosis but show impaired repair of damaged nerves.
ST8SIA1,也称为α-2,8-Sialyltransferase 1,是一种重要的唾液酸转移酶。唾液酸转移酶参与唾液酸的合成,唾液酸是细胞表面糖蛋白和糖脂的重要组成部分,参与细胞的信号传导、细胞粘附、细胞识别和免疫调节等生物学过程。ST8SIA1在多种癌症中发挥重要作用,包括肾细胞癌、乳腺癌、神经母细胞瘤和结直肠癌。

ST8SIA1在肾细胞癌中高表达,与肿瘤的进展和预后不良相关。ST8SIA1的表达水平与肿瘤的分期和TNM分期相关,高表达的ST8SIA1与更差的总体生存率相关。此外,ST8SIA1的表达水平与肿瘤纯度呈负相关,与浸润免疫细胞和免疫检查点基因的表达呈正相关[1]。在乳腺癌中,ST8SIA1的表达也与预后不良相关。ST8SIA1的高表达与较差的总体生存率和无病生存率相关,特别是在三阴性乳腺癌患者中[2]。此外,ST8SIA1的表达与乳腺癌干细胞样细胞的特征相关,通过激活FAK-AKT-mTOR信号通路促进肿瘤生长和转移[6]。在神经母细胞瘤中,ST8SIA1的表达与对GD2免疫疗法的抗性相关。YAP基因的表达下调ST8SIA1,从而抑制GD2的表达,导致对GD2免疫疗法的抗性[3]。在结直肠癌中,ST8SIA1的表达与肿瘤的进展和预后不良相关。ST8SIA1的高表达与较差的总体生存率相关,并且与CD8+ T细胞的杀伤作用增强相关[4]。

此外,ST8SIA1的表达还受到表观遗传调控的影响。在乳腺癌中,雌激素可以通过抑制NFκB的结合来抑制ST8SIA1的表达[5]。在胶质瘤中,DNA甲基化可以调节ST8SIA1的表达,影响肿瘤的表型[7]。在膀胱癌中,ST8SIA1的表达下调,通过阻断JAK/STAT信号通路抑制肿瘤细胞的增殖、迁移和侵袭[8]。

综上所述,ST8SIA1是一种重要的唾液酸转移酶,参与细胞的信号传导、细胞粘附、细胞识别和免疫调节等生物学过程。ST8SIA1在多种癌症中发挥重要作用,包括肾细胞癌、乳腺癌、神经母细胞瘤和结直肠癌。ST8SIA1的表达受到表观遗传调控的影响,并且与肿瘤的进展和预后不良相关。ST8SIA1的研究有助于深入理解唾液酸转移酶在肿瘤发生发展中的作用机制,为肿瘤的诊断和治疗提供新的思路和策略。
