常染色体显性遗传性多囊肾综合征(ADPKD)的特点是有大量的囊性病变。
在受累个体的肾脏内,在ADPKD中形成的两个囊肿可大大扩大肾脏。
肾脏在取代正常的肾脏组织结构的同时,导致肾脏功能和功能的下降。
进展到终末期肾脏疾病,只能通过终身肾透析或肾脏移植来治疗。
移植。作为一种在800~1000人中影响约1%的常见疾病,ADPKD是最常见的疾病之一。
常见的遗传性遗传性疾病。在美国北部,全世界大约有60万人。
1250万,其中包括PKD[1]。因此,ADPKD代表着一个重大的公共卫生和公共卫生问题。
在全球医疗保健和医疗成本中,约有数亿美元(甚至可能超过10亿美元)的成本。
特别是在透析和治疗方面,并降低了可以防止移植和排斥反应的药物的总成本。
此外,这些成本还包括生产率下降和个人生活质量下降的影响。

英文摘要
Project Summary
Autosomal Dominant Polycystic kidney disease (ADPKD) is characterized by numerous cysts
within the kidneys of afflicted individuals. The cysts formed in ADPKD can greatly enlarge the
kidneys while replacing the normal kidney structures, resulting in reduced kidney function and
progression to end-stage renal disease, that can only be treated by lifelong dialysis or kidney
transplants. As a disease that affects 1 in 800~1000 individuals, ADPKD is among the most
common genetic disorders. In the United States, there are 600,000 individuals, and worldwide
12.5 million, with PKD [1]. Thus, ADPKD represents a major public health issue, and
accounts for hundreds of millions (and perhaps over a billion) of dollars in health care costs,
particularly for dialysis treatments and the cost of drugs that prevent transplant rejections, as
well as the cost involved of decreased productivity and impaired quality of life of individuals
with ADPKD. For all these reasons, it is of great importance to discover treatments that
directly affect the molecular causes of ADPKD, and that will prevent the progression to end-
stage renal disease and dialysis or transplantation.
Over the past 5 years the Kreidberg laboratory has investigated the role of Wnt signaling in
the pathogenesis of ADPKD. Dr. Kreidberg’s laboratory has found that Wnt signaling and β-
catenin expression is highly elevated in cyst lining cells in ADPKD. In this grant they propose
to extend their studies to understand how a putative β-catenin target gene, fibronectin, affects
cyst formation. Fibronectin is a key extracellular matrix gene primarily found in a
mesenchymal matrix, but over-expressed in cystic kidneys. We will study the role of
integrin:fibronectin interactions in ADPKD.
