Despite significant advances in targeted and immune therapies, treatment resistance and recurrence continue to pose major challenges, underscoring the urgent need for novel therapeutic strategies. Jing-Si Herbal Tea (JSHT), a traditional Chinese medicine (TCM) formulation, has demonstrated anti-tumor, anti-inflammatory, and antioxidant properties; however, its mechanisms of action in kidney disease and cancer remain poorly understood.</p><p><strong>Methods: </strong>Human proximal tubule epithelial (HK-2) cells were treated with various concentrations of JSHT (0%, 4%, and 8%) for 24 and 48 hours.

However, validation in RCC-specific models and in vivo systems is necessary. A notable limitation of this study is the use of a non-cancerous renal cell line; thus, the in vitro findings may not fully recapitulate tumor biology. Future studies employing RCC cell lines, patient-derived tumor models, and in vivo validation are warranted to elucidate the therapeutic potential of JSHT as a complementary approach for RCC management.</p>","PeriodicalId":14595,"journal":{"name":"Iranian Journal of Pharmaceutical Research","volume":"24 1","pages":"e166286"},"PeriodicalIF":1.8,"publicationDate":"2025-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12673877/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145677659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
