Project description:FaDu treated with citric buffer vs. rCTGF FaDu treated with citric buffer for 24 hours FaDu treated with rCTGF 100 ng/mL for 24 hours
Project description:By employing a global gene expression profiling, we performed the differential gene expression analysis and the analysis of the molecular pathways which are deregulated in Hyperthermia (HT) and Radiation therapy (RT) treated SAS and FaDu spheroids from the head-and-neck cancer cell lines. The RNA-Seq analysis was done on FaDu and SAS spheroids treated with clinically relevant HT dose of 42.5°C for 60 minutes alone or in combination of single dose irradiation of 7 and 10 Gy for FaDu and SAS, respectively. The main pathways and networks modulated by the treatments (0.5 h after treatment) were identified using Gene Ontology (GO) enrichment analysis.
Project description:Cisplatin is a common chemotherapeutic drug for hypopharyngeal cancer. But cisplatin-resistance of hypopharyngeal cancer is rarely explored. We cultured hypopharyngeal cancer cell (FaDu) and induced its cisplatin-resistant cell (FaDu/DDP4). The resistance index (RI) of FaDu/DDP4 was 2.828. Then we tested the differentially expressed genes (DEGs) between FaDu and FaDu/DDP4. DEGs contain 2388 lncRNAs, 1932 circRNAs, 745 mRNAs and 202 miRNAs. We used Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyzed the DEGs. The differentially expressed 745 mRNAs were classified into 3 domains and 47 secondary GO terms. In KEGG pathway enrichment, “TNF signaling pathway”, “IL-17 signaling pathway” and “JAK-STAT signaling pathway” have greater enrich factors. And we drew the ceRNA networks of DEGs. 52 lncRNAs, 148 circRNAs, 155 mRNAs and 18 miRNAs were selected to draw the network. We noticed several potential targets (as miR-197-5p, miR-6808-5p, APOE, MMP1, S100A9 and CYP24A1). At last, we chose 8 miRNAs and 6 mRNAs for qRT-PCR to verify our microarray. In them, miR-197-5p, miR-6808-5p, APOE, MMP1, S100A9 and CYP24A1 might be potential genes inducing resistance.
Project description:In order to examine how FOSL1 affects the global gene transcriptome in HNSCC, we performed RNA-sequencing in SCC1 and FaDu cells treated with FOSL1 siRNA. Depletion of FOSL1 led to inhibition of cancer stemness genes.
Project description:FaDu cells were infected with lentivirus containing sh-luciferase plasmid to compared with cells infected with sh-G9a containing lentivirus. We performed microarray analysis to identify the genes possibly regulated by G9a in FaDu cells
