The invention discloses the application of PPM1A in the treatment and diagnosis of asthma. The application of PPM1A as a detection target in the preparation of diagnostic reagents for bronchial asthma. Application of PPM1A reagent in the preparation of bronchial asthma diagnostic reagent. Application of PPM1A as a therapeutic target in the preparation or screening of drugs for bronchial asthma Application of substances that inhibit the expression of PPM1A in the preparation of drugs for bronchial asthma. The invention discloses the application of detecting PPM1A in patients with bronchial blood plasma. For the first time, the expression difference of PPM1A in asthma and normal people is found, and the index can be used as a molecular marker of bronchial asthma. The present invention also discovers for the first time PPM1A as a target gene of microRNA 1165 3p, which promotes Th2 differentiation through STAT1, STAT5 and Akt pathways, leading to the occurrence of asthma. Therefore, it can be used as a therapeutic target for asthma.

PPM1A在哮喘治疗及诊断中的应用
本专利技术属于生物医药领域,涉及PPM1A在哮喘治疗及诊断中的应用。
技术介绍
支气管哮喘是一种以慢性气道炎症、气道重塑,气道高反应性为特征的异质性疾病。全世界约有3亿哮喘患者,我国哮喘患者人数超过300万。近年来,随着工业化的进展,我国哮喘的患病率仍在逐年上升,带来了沉重的家庭和社会负担。由于哮喘的异质性,哮喘具有多种表型和内型。全球哮喘防治创议(GINA)2018将哮喘分为以下几种表型:过敏性哮喘、非过敏性哮喘、迟发型哮喘、哮喘伴固定气流受限、哮喘伴肥胖。不同表型的哮喘人群对于药物尤其是吸入性糖皮质激素(ICS)的治疗反应也不尽相同。哮喘的反复发作还会引起各种并发症,比如肺气肿,肺心病,心衰等。传统的哮喘诊断主要依靠临床表现,肺功能检查,峰流速检测,但上述技术不易检测到症状不明显的哮喘患者,随着生物技术的发展,生物标志物为哮喘的诊断提供了一种新的途径。PPM1A(镁离子依赖的蛋白磷酸酶1Aα异构体):PPM1A是丝素蛋白磷酸酶PP2C的家族成员,胞核与胞浆中均有分布,能够与多种蛋白结合使其去磷酸化。过往在肿瘤领域对PPM1A ...
