Project description:To determine the signaling networks that are dysregulated in cisplatin-resistant non-small cell lung cancer, noncoding RNA expression data were obtained from, and compared between, the lung adenocarcinoma cell line, A549, and its cisplatin-resistant derivative, A549/CDDP. Noncoding RNA expression data from a cisplatin-sensitive lung adenocarcinoma cancer cell line (A549) were collected and compared to noncoding RNA expression data from a cisplatin-resistant cell line (A549/CDDP). 3 independent experiments were completed for both the sensitive and resistant cell lines.

Project description:The cellular transcriptome of untreated and cisplatin-treated A549 non-small cell lung cancer cells and their cisplatin-resistant sub-line A549rCDDP2000 was screened with a whole genome array for gene candidates relevant for cisplatin resistance.
Project description:Cisplatin resistance is a major therapeutic challenge in advanced head and neck squamous cell carcinoma (HNSCC). Here, we aimed to investigate the key signaling pathway for cisplatin resistance in HNSCC cells. HNSCC cell lines that were sensitive (HN4 and HN30) or resistant (HN4/DDP and HN30/DDP) to cisplatin were used for this study. Moreover, the cisplatin-resistant human melanoma cell lines (A375/DDP) and human lung cancer cell lines (A549/DDP) have also been established. To identify the role of proteins in the acquisition of cisplatin resistance, we analyzed the abnormally expressed protein via protein mass spectrometry methods (isobaric tags for relative and absolute quantitation, iTRAQ) in cisplatin-sensitive and cisplatin-resistant cancer cells, and found that VN1R5 was highly expressed in cisplatin-resistant cells. Long noncoding RNA lnc-POP1-1 upregulated by VN1R5. To deeply investigate the mechanism by which lnc-POP1-1 affects cisplatin resistance in HNSCC cells, we used RNA pull-down assays followed by mass spectrometry to explore the putative RNA-binding proteins (RBPs) interacting with lnc-POP1-1.
Project description:This study aims to identify pathway involvement in the development of cisplatin (cis-diamminedichloroplatinum (II); CDDP) resistance in A549 lung cancer (LC) cells by utilizing advanced bioinformatics software. We developed CDDP-resistant A549 (A549/DDP) cells through prolonged incubation with the drug and performed RNA-seq on RNA extracts to determined differential mRNA and miRNA expression between A549/DDP and A549 cells
