Its progressively expanding, fluid-filled renal cysts eventually lead to end-stage renal disease. Despite the relatively high prevalence, treatment options are currently limited to a single drug approved by the FDA and EMA. Here, we investigated human ADPKD patient-derived three-dimensional cyst cultures (3DCC) as an in vitro model for ADPKD and drug repurposing research. First, we analyzed the proteomes of 3DCC derived from healthy and diseased tissues. We then compared the protein expression profiles with those of reference tissues, mainly from the same patients. We quantified 290 proteins affecting drug disposition and proposed target proteins for drug treatment. Lastly, we investigated the functional response of the quantified target proteins after exposure to repurposing candidates in the 3DCC. Proteomic profiling of human 3DCC reflected previously reported pathophysiological alterations, including aberrant protein expression in inflammation and metabolic reprogramming. While the 3DCCs largely recapitulated the disease phenotype in vitro, drug transporter expression was reduced compared to in vivo conditions. Target proteins for proposed repurposing candidates showed similar expression in vitro and in tissues. Exposure to these repurposing candidates inhibited cyst swelling in vitro, supporting the suitability of the 3DCC for ADPKD drug screening. In summary, our results provide new insights into the ADPKD proteome and offer a starting point for further research to improve treatment options for affected individuals.</p>","PeriodicalId":50610,"journal":{"name":"Cts-Clinical and Translational Science","volume":"18 4","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cts.70214","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143836094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As digital health technologies (DHTs) measuring PA rapidly evolve, there is an opportunity to further define concepts. A systematic review of qualitative studies to identify concepts of PA that are meaningful to patients and care providers was conducted. Conditions covered included Parkinson's disease, multiple sclerosis, chronic obstructive pulmonary disease, cancer, Duchenne muscular dystrophy, chronic heart failure, sickle cell disease, osteoarthritis, and sarcopenia. We analyzed studies published in the last 20 years utilizing qualitative or mixed methods techniques to describe aspects of PA that patients want to prevent from worsening or improve.

Thematic synthesis revealed five meaningful aspects of health (MAH) related to PA: ambulation-dependent activities, balance-dependent activities, activities needing upper limb function, changing body positions, and participating in activities of different intensities. Patients also reported PA as important to QOL and influenced by internal and external facilitators and barriers.

While there is broad enthusiasm around the potential of artificial intelligence (AI) among HEOR researchers [&lt;span&gt;1&lt;/span&gt;], there are challenges related to its widespread adoption. First, there are a variety of approaches that fall under the AI umbrella, including generative AI based on natural language processing (NLP), large language models (LLMs), and machine learning (ML) methods that classify, cluster, and predict outcomes. Each has potential distinct roles in HEOR, but there are few published evaluations of how these technologies can be practically applied across a breadth of research areas. Second, stakeholder perspectives may impact the value of AI. For example, within the pharmaceutical industry, AI end-users may be interested in more efficient execution of rote tasks, while regulatory bodies and health technology assessment (HTA) agencies, with a wider-ranging public health purview, advise a cautious approach that upholds established scientific practices while ensuring compliance with legal, ethical, data protection requirements and quality standards [&lt;span&gt;2&lt;/span&gt;].&lt;/p&gt;&lt;p&gt;Herein, we examine the current practical and potential future applications of AI across activities critical to payor reimbursement in HEOR.
