项目摘要

Uterine leiomyomas (UL), also known as uterine fibroids, are benign smooth muscle tumors with excessive depostition of extracellular matrix proteins. UL is a major health problem worldwide, because it affects almost 70-80% of all women and disproportionally African Americans, but still remains poorly understood. The long term goal of our team is to systematically discover novel mechanisms regulating key molecular events that contribute to leiomyoma. The immediate goal of this R01 application is to test the hypothesis that altered epigenomic signatures define normal myometrial tissues and leiomyomas, and therapy treated human tissues. Using genome-wide studies integrated with bioinformatic and other analyses, we will determine the epigenomic signatures in uterine fibrosis for the first time. This unbiased study will identify epigenomic differentiating features of normal and diseased tissues and may allow for development of Epitherapy (targeting the epigenome) for leiomyomas The proposed work is scientifically, translationally, and clinically significant and highly innovative because it represents the first systematic exploration of the epigenome in leiomyomas. Results obtained from this analysis will be used to generate new hypotheses to better understand the molecular underpinning of leiomyomas.

子宫肌瘤（UL），也称为子宫肌瘤，是一种良性平滑肌肿瘤，细胞外基质蛋白的沉积。 UL 是世界范围内的一个主要健康问题，因为它几乎影响 70-80% 的女性和不成比例的非裔美国人，但仍然知之甚少。长的我们团队的长期目标是系统地发现调节关键分子事件的新机制有助于平滑肌瘤。此 R01 应用程序的直接目标是测试改变的假设表观基因组特征定义了正常子宫肌层组织和平滑肌瘤，以及治疗后的人体组织。利用与生物信息学和其他分析相结合的全基因组研究，我们将确定表观基因组首次发现子宫纤维化的特征。这项公正的研究将确定表观基因组差异正常组织和患病组织的特征，并可能允许开发 Epitherapy（针对表观基因组）用于平滑肌瘤拟议的工作具有科学性、转化性和临床意义，并且具有高度创新性因为它代表了对平滑肌瘤表观基因组的首次系统探索。结果来自该分析将用于产生新的假设，以更好地理解分子基础平滑肌瘤。
