亚斯巴酸酶 (ASPA) 通过降低LYN信号的调节来抑制前列腺癌 (PCa) 的进展. 降低ASPA表达与预后不佳相关,这表明ASPA是PCa的潜在治疗标.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 癌症研究 癌症研究
背景情况:
- 前列腺癌 (PCa) 是男性的主要恶性瘤,其致病机制尚不清楚.
- 确定关键的分子调节剂对于开发新型PCa疗法至关重要.
研究的目的:
- 调查阿斯巴尔托酶 (ASPA) 在前列腺癌 (PCa) 进展中的作用.
- 阐明ASPA在PCa中的功能背后的分子机制.
主要方法:
- 转录组分析以确定PCa中差异表达的基因.
- 定量实时PCR和西部抹杀来评估ASPA表达.
- 在体外和体内测试 (正位体和瘤携带的小鼠模型) 来评估ASPA的功能作用.
- 使用共免疫沉,质谱和光酶试验进行分子机制调查.
- 统计分析包括学生的t测试和单向ANOVA.
主要成果:
- 在PCa组织中,ASPA表达显著下调,并与患者预后不佳有关.
- 调节ASPA水平会影响PCa细胞的增殖,迁移和入侵在体外和体内.
- ASPA直接与LYN激酶相互作用,以酶独立的方式抑制其酸化和下游信号 (JNK1/2,C-Jun).
- 巴菲蒂尼布对LYN的抑制抵消了ASPA对PCa进展的抑制作用.
结论:
- 在前列腺癌 (PCa) 中,ASPA表现出瘤抑制功能.
- ASPA通过抑制LYN信号通路而起作用.
- ASPA是PCa管理的潜在预后生物标志物和治疗目标.

Allosteric Proteins-ATCase
Aspartate transcarbamoylase (ATCase) is a cytosolic enzyme that catalyzes the condensation of L-aspartate and carbamoyl phosphate to N-carbamoyl-L-aspartate. This reaction is the first step in pyrimidine biosynthesis. UTP and CTP, the end products of the pyrimidine synthesis...
