Methods, pharmaceutical compositions and applications.
背景技术Background technique
真核生物基因的转录因子存在广泛，可调控多种靶基因，与肿瘤细胞的生长、增殖、凋亡、浸润转移及血管生成等各个环节密切相关。Snail为锌指转录因子，其通过蛋白结构中的锌指结构与以E-box(CAGGTG)为核心的下游靶基因启动子结合，参与下游基因转录、抑制染色质结构形成等过程，使机体维持正常生物学功能。在正常生理条件下，细胞内Snail蛋白含量非常有限，维持在无活性的低水平状态。当细胞受到氧化应激等刺激后，Snail mRNA的翻译速度加快、入核能力增强；Snail mRNA聚集于细胞核，使蛋白稳定性增加，从而增强了调控下游目的基因的转录活性，并对细胞周期阻滞、凋亡抵抗、侵袭与转移、免疫调节等多个过程产生影响。因此，保证Snail适时、适度的调控是确保其正常行使转录功能的必要条件。There are a wide range of transcription factors for eukaryotic genes, which can regulate a variety of target genes, and are closely related to the growth, proliferation, apoptosis, infiltration, metastasis, and angiogenesis of tumor cells. Snail is a zinc finger transcription factor, which combines the zinc finger structure in the protein structure with the downstream target gene promoter with E-box (CAGGTG) as the core, participates in downstream gene transcription, inhibits the formation of chromatin structure and other processes to maintain the body Normal biological function. Under normal physiological conditions, the content of Snail protein in cells is very limited and maintained at an inactive low level. When cells are stimulated by oxidative stress, the translation speed of Snail mRNA increases and the ability to enter the nucleus is enhanced; Snail mRNA accumulates in the nucleus to increase protein stability, thereby enhancing the transcriptional activity of downstream target genes and inhibiting the cell cycle. Multiple processes such as stagnation, apoptosis resistance, invasion and metastasis, and immune regulation have an impact. Therefore, ensuring that Snail's timely and appropriate regulation is necessary to ensure its normal function of transcription.
Snail的转录异常在乳腺癌、结肠癌、肺癌等多种类型的肿瘤中均可检测到，并预示着肿瘤的不良预后。Snail可以抑制细胞周期D2(Cyclin D2)的转录，增加p21Cip1/WAF1表达，促进肿瘤细胞生长；也可以激活p53介导的凋亡抵抗通路，抑制肿瘤细胞凋亡。Snail作为EMT(间质上皮转化)的关键调控因子，可以使肿瘤进程加快；还可以促进免疫抑制因子表达，从而使肿瘤细胞产生免疫抵抗。因此，Snail在肿瘤恶化进程中起着核心节点性作用。Snail's transcription abnormality can be detected in many types of tumors, such as breast cancer, colon cancer, and lung cancer, and indicates a poor prognosis of the tumor. Snail can inhibit the transcription of cell cycle D2 (Cyclin D2), increase the expression of p21Cip1/WAF1, and promote the growth of tumor cells; it can also activate the p53-mediated apoptosis resistance pathway to inhibit tumor cell apoptosis. Snail, as a key regulator of EMT (Mesenchymal Transformation), can accelerate tumor progression; it can also promote the expression of immunosuppressive factors, so that tumor cells can produce immune resistance. Therefore, Snail plays a central role in tumor progression.
