Project description:Oncogenic human papillomaviruses (HPVs) are associated with nearly all carcinomas of the uterine cervix and have also become an increasingly important factor in the etiology of a subset of oropharyngeal tumors. HPV-associated head and neck cancers (HNSCCs) have a distinct risk profile and appreciate a prognostic advantage compared to HPV-negative HNSCC. We analyzed the genome-wide expression patterns in two HPV(+) and two HPV(-) squamous cell carcinoma (SCC) cell lines. The Affymetrix Human Genome U133 Plus 2.0 Array platform was used to assess genome-wide expression differences between the HPV(+) and HPV(-) cell lines utilizing the RMA normalization package available for R. Cell lines analyzed: UM-SCC-4, UM-SCC-47, UM-SCC-74A, and CaSki.
Project description:Primary objectives: The primary objective is to investigate circulating tumor DNA (ctDNA) via deep sequencing for mutation detection and by whole genome sequencing for copy number analyses before start (baseline) with regorafenib and at defined time points during administration of regorafenib for treatment efficacy in colorectal cancer patients in terms of overall survival (OS).

Project description:We analysed active enhancers in UPCI-SCC-090, UM-SCC-104, FaDu and NP69SV40T by performing ChIP-seq on H3K4me3, H3K4me1 and H3K27ac.
Project description:We treated primary keratinocytes and SCC cells with IM for 24h to identify differentially expressed genes after treatment compared to DMSO contorl 3x DMSO keratinocytes, 3x IM 100 nM IM keratinocytes, 3x 10 uM IM keratinocytes, 3x DMSO SCC cells, 3x 1 nM IM SCC cells, 3x 100 nM IM SCC cells, 3x 10 uM IM SCC cells
Project description:Whole-genome bisulfite sequencing (WGBS) is currently the gold standard for DNA methylation (5-methylcytosine, 5mC) profiling, however the destructive nature of sodium bisulfite results in DNA fragmentation and subsequent biases in sequencing data. Such issues have led to the development of bisulfite-free methods for 5mC detection. Nanopore sequencing is a long read non-destructive approach that directly analyzes DNA and RNA fragments in real time. Recently, computational tools have been developed that enable base-resolution detection of 5mC from Oxford Nanopore sequencing data. In this chapter we provide a detailed protocol for preparation, sequencing, read assembly and analysis of genome-wide 5mC using Nanopore sequencing technologies.
Project description:Two HPV(+) head and neck cancer cell lines (UPCI-SCC-090, UM-SCC-104), one HPV(–) head and neck cancer cell line (FaDu) and one nasopharyngeal epithelial cell line (NP69SV40T) were subjected to RNA-seq analysis.
