Project description:Genome wide DNA methylation profiling in cutaneous squamous cell carcinoma. The Infinium MethylationEPIC BeadChips 850K has been used to interrogate DNA methylation changes. The cohort included 23 patients in total, with precursors of squamous cell carcinoma (actinic keratosis group) and with cSCC at different stages.
Project description:The expression of lncRNAs in cutaneous squamous cell carcinoma (cSCC) were determined with a commercially available microarray (Arraystar Inc.,Rockville, Maryland USA). The Arraystar human lncRNA Microarray V3.0 containing 30,586 LncRNAs and 26,109 coding transcripts (mRNAs) A total of three patients with cSCC were biopsied. A total of three control (non-lesional skin) were biopsied.

Project description:Interactions between cells and the extracellular matrix, mediated by integrin adhesion complexes (IACs), play key roles in cancer progression and metastasis. We report here systems-level changes in the adhesome during progression of a patient-derived cutaneous squamous cell carcinoma (cSCC). We found that the actin regulatory protein Mena is enriched in IACs in metastatic cSCC cells and is connected within a subnetwork of actin-binding proteins to the LINC complex component nesprin-2.
Project description:Analysis of the combined dataset of normal skin, actinic keratosis and cutaneous squamous cell carcinoma (cSCC) previously submitted in (GSE45216) at genomic/transciptomic level. We identified potential cSCC driver genes significantly mutated and upregulated in cSCC relative to normal skin.
Project description:The incidence of keratinocyte-derived skin cancer, cutaneous squamous cell carcinoma (cSCC) is increasing worldwide making it the second most common metastatic skin cancer. In this project we used SOLiD next generation sequencing to characterize gene expression profiles in normal human epidermal keratinocytes (NHEKs) and cSCC cell lines. Total RNAs from normal human epidermal keratinocytes (NHEKs) (n=4) and cSCC cell lines (n=8) were extracted. The samples were sequenced using SOLiD next generation sequencing.
Project description:Keratinocyte-derived cutaneous squamous cell carcinoma (cSCC) is the most common metastatic skin cancer, and its incidence is increasing globally. Long non-coding RNAs (lncRNAs) are involved in various biological processes, and their role in cancer progression is emerging. Whole transcriptome analysis of cSCC cells (n=8) and normal human epidermal keratinocytes (NHEKs, n=4) revealed overexpression of long intergenic ncRNA (LINC00162) in cSCC cells (GSE66412). We wanted to futher study the RNA expression profile of LINC00162 knockdown cSCC cells. Based on our observations, LINC00162 was named PICSAR (P38 Inhibited Cutaneous Squamous cell carcinoma Associated lincRNA).
Project description:The incidence of keratinocyte-derived skin cancer, cutaneous squamous cell carcinoma (cSCC) is increasing worldwide making it the second most common metastatic skin cancer. We used microarrays to characterize gene expression profile in normal human epidermal keratinocytes (NHEK) and cSCC cell lines. Total RNAs from normal human epidermal keratinocytes (n=5) and cSCC cell lines (n=8) were extracted. The samples were processed for Affymetrix 3´ IVT Express Kit according to manufacture’s protocol.
Project description:Cutaneous squamous cell carcinoma (cSCC) is the second most commonly diagnosed cancer in the United States each year. Despite a generally good prognosis, metastatic cSCC results in over 3500 deaths annually. There are no specifically targeted therapies or biomarkers for metastatic cSCC. To determine whether aberrant microRNA expression occurs in metastatic cSCC which could provide novel targets for therapy or biomarkers for earlier diagnosis or prognosis, microRNA expression profiling was performed in 48 samples including normal skin, primary tumors and metastases. Multiple microRNAs showed differential expression; miR-4286, miR-200a-3p and miR-148-3p showed increased expression and miR-1915-3p, miR-205-5p, miR-4516 and miR-150-5p showed reduced expression in metastatic samples. Several microRNAs previously showing aberrant expressionshown to be aberrantly expressed in primary cSCCs were also observed in this study including miR-100, miR-135b, miR-145, miR-21, and miR-214. In summary, several microRNAs show differential expression between primary and metastatic cSCCs; these may be useful as biomarkers for metastasis or as targets for therapytherapeutic targets.
