Despite significant advancements in therapeutic strategies and a deeper understanding of targeted therapies in recent years, tumor resistance remains an inevitable challenge, leading to poor prognostic outcomes. Several studies have indicated that sphingosine kinase 1 (SPHK1) plays a regulatory role in epidermal growth factor receptor (EGFR) signaling, and its elevated expression may be associated with resistance to EGFR tyrosine kinase inhibitors (EGFR-TKIs). Furthermore, the catalytic product of SPHK1, sphingosine 1-phosphate (S1P), along with its receptor, sphingosine 1-phosphate receptor 3 (S1PR3), plays a regulatory role in the function of the EGFR. However, the specific effects of the SPHK1/S1P/S1PR3 axis on EGFR in NSCLC, as well as the combined effects of SPHK1/S1P/S1PR3 inhibitors with the EGFR-TKI gefitinib, remain to be elucidated. In the present study, we investigated the correlation between SPHK1 expression levels and the survival rates of NSCLC patients, the relationship between SPHK1 or S1PR3 and EGFR, and the impact of SPHK1 expression on the half-maximal inhibitory concentration (IC₅₀) of gefitinib in NSCLC. In A549 cells, the phosphorylation of EGFR was significantly reduced following SPHK1 knockdown. Utilizing SPHK1/S1P/S1PR3 inhibitors, namely PF543, TY52156, and FTY720, we established that the SPHK1/S1P/S1PR3 axis modulates EGFR activation in NSCLC. Furthermore, these signaling inhibitors enhanced the anti-proliferative efficacy of the EGFR-TKI gefitinib. RNA sequencing analysis revealed substantial alterations in 85 differentially expressed genes in NSCLC cells treated with the combination of FTY720 and gefitinib. These genes were predominantly associated with pathways such as axon guidance, microRNAs in cancer, and the JAK-STAT signaling pathway, among others. Overall, targeting the SPHK1/S1P/S1PR3 signaling pathway represents a promising therapeutic strategy to enhance gefitinib sensitivity in NSCLC.</div></div>","PeriodicalId":10877,"journal":{"name":"Current Research in Pharmacology and Drug Discovery","volume":"8 ","pages":"Article 100212"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11787445/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143078650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite therapeutic advancements, chemoresistance remains a major challenge, limiting the efficacy of docetaxel and contributing to treatment failure and disease progression. Multidrug resistance (MDR), primarily mediated by ATP-binding cassette (ABC) transporters such as ABCC1 and ABCC10, has been implicated in reduced chemotherapy effectiveness. This study aimed to evaluate the association between ABCC1 and ABCC10 expression levels and docetaxel treatment response in PCa patients. A retrospective case-control study was conducted using pre-treated formalin-fixed paraffin-embedded (FFPE) tissue biopsies from PCa patients. Patients were classified into good responders (cases) and poor responders (cases) based on treatment outcomes. For each patient, tumour and adjacent normal sections were excised from FFPE samples, with normal sections serving as the control group. RNA was extracted and subjected to quantitative real-time PCR (qRT-PCR) to assess ABCC1 and ABCC10 expression levels. ABCC1 and ABCC10 were significantly upregulated in tumour sections of poor responders, whereas good responders exhibited downregulated expression in tumour sections. Importantly, normal tissue sections (controls) displayed significantly lower expression levels of both transporter genes compared to tumour sections. The overexpression of ABCC1 and ABCC10 in tumour tissues, particularly in poor responders, suggests their potential role in mediating docetaxel resistance. These findings highlight ABCC1 and ABCC10 as potential predictive biomarkers for docetaxel treatment response in PCa, warranting further investigation in prospective clinical studies.</div></div>","PeriodicalId":10877,"journal":{"name":"Current Research in Pharmacology and Drug Discovery","volume":"8 ","pages":"Article 100216"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143705523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
