Transcriptome drift of FADU after expression of HIF-1a, Twist1 or Bmi1

Project description:Expression of HIF-1a or Twist1 or Bmi1 in human hypopharyngeal cancer cell line FADU results in the drift of transcriptome profile from an epithelial cell-like signature to a mesenchymal stem cell-like signature. Stable transfection of pHA-HIF1a(dODD), pFLAG-Twist1 or pcDNA3-Bmi1 in FADU cell and analyzed the transcriptome by cDNA microarray. FADU transfected with pcDNA3.1 empty vector was used as a control of experiment.

Analysis of differentially expressed lncRNA, circRNA and mRNA between FaDu and cisplatin-resistant FaDu cell

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.

Regulation of downstream pathway of NSUN2 knockdown in hypopharyngeal carcinoma FaDu cell line

Project description:It has been confirmed that nsun2 promotes cell proliferation and migration in hypopharyngeal cancer cell lines, but the pathway of nsun2 in hypopharyngeal cancer cell lines is poorly understood. We constructed stable cell lines by knocking down nsun2 to find the key genes of downstream pathway, and compared them with normal FaDu cell lines.It has been confirmed that nsun2 promotes cell proliferation and migration in FaDu cell line, but the pathway of nsun2 in FaDu cell line is poorly understood.

Differentially expressed genes after miRNA or siRNA transfection in human cancer cell lines Panc-1, FaDu and PC3

Project description:To identify differentially expressed genes by anti cancer treatments (microRNAs or siRNAs) in human cancer, several cell lines (pancreatic cancer, hypopharyngeal squamous cell carcinoma and prostate cancer) were subjected to Agilent whole genome microarrays. Human cell lines (Panc-1, FaDu and PC3) were treated with miRNAs (miR99a-5p, miR-99a-3p, miR-100-3p, miR-150-5p and miR-150-3p), siRNAs (si-FOXQ1).

Transcriptional profiling of 2D colonies derived from WT, Bmi1-/-, and Bmi1-/-;Ink4a/Arf Labial cervical loops

Project description:This experiment is aimed at determining the genetic signature of dental stem cell colonies grown in vitro and how that signature changes when Bmi1 activity is removed. Another question to be answered by the experiment is whether Bmi1 has alternate targets besides Ink4a/Arf.
