It is imperative to employ a comprehensive approach to obtain a better account of cisplatin-mediated changes in the expression of lncRNAs. In this study, we used a transcriptomics approach to profile lncRNAs in cisplatin-treated HeLa cells, which resulted in identification of 10,214 differentially expressed lncRNAs, of which 2,500 were antisense lncRNAs. For functional analyses, we knocked down one of the cisplatin inducible lncRNAs, death receptor 5 antisense (DR5-AS) lncRNA, which resulted in a morphological change in HeLa cell shape without inducing any cell death. A second round of transcriptomics-based profiling revealed differential expression of genes associated with immune system, motility and cell cycle in DR5-AS knockdown HeLa cells. Cellular analyses showed that DR5-AS reduced cell proliferation and caused a cell cycle arrest at S and G2/M phases. Moreover, DR5-AS knockdown reduced the invasive capacity of HeLa cells in zebrafish xenograft model. These results suggest that cisplatin-mediated pleiotropic effects, such as reduction in cell proliferation, metastasis and cell cycle arrest, may be mediated by lncRNAs. © Copyright © 2021 Gurer, Erdogan, Ahmadov, Basol, Sweef, Cakan-Akdogan and Akgül.Conference Object Citation - WoS: 2Incorporation of Equisetum Arvense Extract Into Silk Fibroin-Hyaluronic Acid Sponge Matrices for Wound Dressing Applications(Elsevier, 2012) Uslu, Mehmet Emin; Erdoğan, İpek; Bayraktar, OğuzEquisetum arvense extract has frequently been investigated for its antioxidant capacity, antimicrobial and antitumor properties. However, one of the challenges in natural compound investi-gations is to maintain the stability of polyphenolic compounds during their storage and applications. For this purpose extracts can be incorporated into different forms of biomaterial. In this research silk fibroin (SF) and hyaluronic acid (HA) was used as sponge matri-ces for wound dressing application.
