Therefore, this study aimed to investigate the impacts of subtoxic concentrations of zinc oxide (ZnO NPs) on breast cancer cells’ response to Doxorubicin. Zinc oxide nanoparticles caused a concentration-dependent reduction of cell viability in multiple breast cancer cell lines. A subtoxic concentration of 1.56 µg/mL (i.e., no observed adverse effect level) was used in subsequent mechanistic studies. Molecularly, miRNA profiling revealed significant downregulation of 13 oncogenic miRNAs (OncomiRs) in cells exposed to the sub-toxic dose of ZnO NPs followed by doxorubicin treatment. Our comprehensive bioinformatic analysis has identified 617 target genes enriched in ten pathways, mainly regulating gene expression and transcription, cell cycle, and apoptotic cell death. Several tumor suppressor genes emerged as validated direct targets of the 13 OncomiRs, including TFDP2, YWHAG, SMAD2, SMAD4, CDKN1A, CDKN1B, BCL2L11, and TGIF2. This study insinuates the importance of miRNAs in regulating the responsiveness of cancer cells to chemotherapy. Our findings further indicate that being exposed to environmental ENMs, even at levels below toxicity, might still modulate cancer cells’ response to chemotherapy, which highlights the need to reestablish endpoints of ENM exposure and toxicity in cancer patients receiving chemotherapeutics.</p></div>","PeriodicalId":49257,"journal":{"name":"Saudi Pharmaceutical Journal","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1319016424002196/pdfft?md5=89b0a527c15a586b078e5b5ff7827b41&pid=1-s2.0-S1319016424002196-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142239278","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}

This review article features the significant strides made by the JHAH ambulatory care pharmacy to symbolize Saudi Arabia’s ambitious vision of healthcare transformation. This evolving journey includes details of JHAH’s adoption of modern automation tools, several technological advancements, and establishing a pharmacist role far beyond dispensing medications. Moreover, it underscores the cultivation of patient-centered care initiatives like tele-pharmacy services through pharmacy call center, systematic patient satisfaction surveys, streamlined medication home delivery services, state-of-the-art medication drive-thru pick-up facility, the efficacious Q-Matic patient queue management architecture, and the establishment of discreet individual dispensing cubicles. Key focal points encompass technological enhancements, such as the incorporation of electronic health record Epic, cutting-edge pharmacy automation systems, and the patient-centric online portal MyChart®. The article also summarizes the multifaceted ambulatory care enhancements among clinical pharmacy services offered at JHAH. This includes a pharmacist-led medication management clinic, specialized anticoagulation clinic, psychiatric and hepatitis medication management, renal dose optimization, precision-driven thyroid and benign prostatic hyperplasia patients’ treatment optimization, and clinical decision support system-backed clinical interventions. All these substantial enhancements at JHAH’s ambulatory pharmacy have been made to improve the quality of pharmaceutical services. Besides automation and technological advancements, these also include the establishment of pharmacy competency and continuous education programs, the development of an internal pharmacy webpage on the JHAH website, the implementation of a mechanism for formulary management by the pharmacy and therapeutic committee, and very importantly the adoption of electronic incidence reporting system Datix.
