表型提示
MGI:107252Homozygous inactivation of this gene leads to decreased body size, male sterility, and hair cycle anomalies. Additional phenotypes may include reduced body fat, skeletal, craniofacial and eye defects, abnormal erythropoiesis, and altered energy expenditure and gas, glucose, and lipid homeostasis.
Nsun2,也称为NOP2/Sun RNA甲基转移酶家族成员2,是一种重要的RNA 5-甲基胞嘧啶(m5C)甲基转移酶。m5C是一种普遍存在于真核细胞RNA上的表观遗传修饰,参与调控RNA的稳定性和功能,影响基因表达和生物学过程。Nsun2通过在mRNA、非编码RNA和转移RNA上添加m5C,影响RNA的剪接、稳定性和翻译,从而调控基因表达和细胞功能。

Nsun2在多种疾病中发挥重要作用,包括非小细胞肺癌、胃癌、神经母细胞瘤、子宫内膜异位症、肝细胞癌、视网膜母细胞瘤和食管鳞状细胞癌。在非小细胞肺癌中,Nsun2通过NSUN2/YBX1/QSOX1轴介导对吉非替尼的内在耐药性[1]。在胃癌中,Nsun2通过SUMO-2/3修饰促进肿瘤的进展并调节mRNA m5C甲基化[2]。在神经母细胞瘤中,Nsun2基因rs13181449 C>T多态性与神经母细胞瘤风险的降低相关[3]。在子宫内膜异位症中,Nsun2通过m5C修饰影响子宫内膜容受性,导致反复植入失败[4]。在肝细胞癌中,Nsun2通过m5C修饰调节肿瘤的进展,并影响细胞对索拉非尼的敏感性[5]。在视网膜母细胞瘤中,Nsun2通过m5C修饰促进PFAS mRNA的稳定性和表达,从而促进肿瘤的进展[6]。在食管鳞状细胞癌中,Nsun2通过m5C修饰促进GRB2 mRNA的稳定性和表达,从而促进肿瘤的进展[7]。

Nsun2的研究有助于深入理解RNA表观遗传修饰的生物学功能和疾病发生机制,为疾病的治疗和预防提供新的思路和策略。未来,Nsun2有望成为肿瘤治疗的新靶点,为肿瘤患者带来新的希望。
