摘要: Background Dysregulation of long noncoding RNAs (lncRNAs) is associated with drug resistance in multiple cancers. We explored the roles lncRNA p38 inhibited cutaneous squamous cell carcinoma-associated lincRNA (PICSAR) cisplatin (DDP) carcinoma (CSCC). Methods Quantitative real-time polymerase chain reaction (qRT-PCR) was employed to measure expression lnc-PICSAR, miR-485-5p and reversionless 3-like (REV3L) mRNA. The counting kit-8 (CCK-8) assay conducted evaluate DDP viability. transwell performed determine migration invasion. Western blot immunohistochemistry (IHC) staining were carried out protein levels. dual-luciferase reporter used investigate association between lnc-PICSAR or REV3L. Murine xenograft model constructed explore function vivo. morphology exosomes analyzed by transmission electron microscopy (TEM) nanoparticle tracking analysis (NTA). Results Lnc-PICSAR elevated DDP-resistant CSCC cells. silencing suppressed viability, resistance, invasion MiR-485-5p acted as a target inhibition reversed impacts on progression promoted REV3L via sponging miR-485-5p. Moreover, overexpression overturned effects resistance. knockdown In addition, increased derived from patients' serum Conclusion enhanced miR-485-5p/REV3L axis Besides, exosome-mediated might be involved regulation CSCC.
