项目摘要

Asthma and rhinitis share a strong genetic component and are the most common chronic respiratory diseases worldwide affecting 339 million and 500 million people, respectively. Both allergic and non-allergic rhinitis are well-studied risk factors for the development of asthma, independent of atopy and IgE sensitization, and up to 80% of asthmatics have concomitant rhinitis. Conversely, asthma is also a risk factor for the development of rhinitis suggesting a common pathophysiological link between the upper and lower airways. Individuals with comorbid asthma and rhinitis are more likely to experience frequent and severe asthma exacerbations. Currently, an unmet need exists in the understanding of the comorbid development of asthma and rhinitis, including which patients are at risk and why patients with comorbid disease have increased disease severity. microRNAs (miRNAs) have emerged as important predictive biomarkers and regulators of the pathogenesis of asthma and rhinitis. However, the role of miRNA-messenger RNA (mRNA) regulatory networks in asthma with comorbid rhinitis is not known. The overall hypothesis of this K23 award proposal is that the comorbid development of asthma and rhinitis can be predicted by clinical factors and is regulated by miRNA-mRNA networks. Specific Aim 1 will evaluate the early childhood clinical prediction of the development of comorbid disease in the Vitamin D Antenatal Asthma Reduction Trial (VDAART) and Children, Allergy, Milieu, Stockholm, Epidemiology (BAMSE) cohorts and create a validated clinical prognostic tool to identify high-risk children who may benefit from early monitoring and interventions. Specific Aim 2 will identify the unique miRNA-mRNA pathways and regulatory networks in the peripheral blood that regulate asthma with comorbid rhinitis in children from the VDAART, BAMSE, and Childhood Asthma Management Program (CAMP) cohorts to identify candidate miRNAs and biological pathways that may serve as future targets of miRNA-based therapies and biomarkers. Specific Aim 3 will prospectively validate the miRNA-mRNA signature of asthma with comorbid rhinitis across the peripheral whole blood and local nasal epithelium in subjects recruited from Brigham and Women’s Hospital to identify the shared and tissue-specific pathogenic pathways in the peripheral blood and local primary airway tissue. Through this K23 award proposal, the candidate will complete an integrated plan of mentorship, coursework, conferences, patient-oriented research, statistical and computational analyses, manuscript submissions, and R01 grant preparation. She will develop new knowledge and skills in clinical, translational, and computational research and generate new hypotheses and data that will provide the basis for future independent lines of investigation. With the support of her division, mentors, and scientific advisory committee and the resources available at her institution, the candidate is ideally positioned to achieve her goal of becoming a successful independent investigator in the epidemiology and epigenetics of asthma and allergic diseases.

哮喘和鼻炎具有很强的遗传成分，是最常见的慢性呼吸道疾病全球影响3.39亿和5亿人。过敏和非过敏性鼻炎都是研究哮喘，独立于应对和IgE敏感性的经过充分研究的风险因素，直到 80％的哮喘患者伴有鼻炎。相反，哮喘也是发展的危险因素鼻炎表明上和下气道之间存在常见的病理生理联系。有个人合并症哮喘和鼻炎更有可能经常出现严重的哮喘病情。目前，在理解哮喘和鼻炎的合并发展中存在未满足的需求，包括哪些患者处于危险之中，以及为什么合并症患者疾病严重程度增加。 MicroRNA（miRNA）已成为重要的预测生物标志物和调节剂哮喘和鼻炎。然而，miRNA-Messenger RNA（mRNA）调节网络在哮喘中的作用合并症鼻炎尚不清楚。该K23奖励提案的总体假设是合并症哮喘和鼻炎的发展可以通过临床因素预测，并由miRNA-MRNA调节网络。具体目标1将评估合并症发展的幼儿临床预测维生素D产前哮喘降低试验（VDAART）和儿童，Milieu，Milieu的疾病斯德哥尔摩，流行病学（BAMSE）队列，并创建经过验证的临床探测工具，以识别高风险可能会从早期监测和干预措施中受益的孩子。特定目标2将确定独特 miRNA-mRNA途径和周围血液中调节哮喘的调节网络 VDAART，BAMSE和童年哮喘管理计划（CAMP）的儿童鼻炎确定可能用作基于miRNA的未来靶标的候选miRNA和生物学途径疗法和生物标志物。特定的目标3可能会验证哮喘的miRNA-mRNA特征在周围全血和局部鼻上皮的合并症中，从中招募的受试者 Brigham和妇女医院确定在外周血和局部原发气道组织。通过这项K23奖励建议，候选人将完成一项综合计划，课程，课程，会议，面向患者的研究，统计和计算分析，手稿提交和R01赠款准备。她将发展新知识以及临床，转化和计算研究的技能，并产生新的假设和数据为将来的独立投资线提供基础。在她的部门的支持下，导师和科学咨询委员会及其机构可用的资源，候选人是理想的位置为了实现她成为成功的独立研究者的目标，哮喘和过敏性疾病。
