Project description:Non-melanoma skin cancers (NMSC) including basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) are more common kinds of skin cancer. Although these tumors share common pathological and clinical features, their similarity and heterogeneity at molecular levels are not fully elaborated yet. Here, by performing comparative analysis of gene expression profiling of BCC, SCC, and normal skin tissues, we could classify the BCC into three subtypes of classical, SCC-like, and normal-like BCCs. Functional enrichment and pathway analyses revealed the molecular characteristics of each subtype. The analysis of gene expression profiling among non-melanoma skin cancer types

Project description:DeltaNp73alpha is a major oncogenic isoform of tumor suppressor p73. We report deltaNp73alpha protein binding partners in the organelle and cytoplasmic compartments of a cellular model consisting of human keratinocytes transformed by the E6 and E7 oncoproteins of the beta-HPV38 virus, which is associated with non-melanoma skin cancer.

Project description:Disruption of skin homeostasis by environmental insults activates pathologic circuitries leading to inflammation and carcinogenesis. Galectin-7 (Gal-7), a lectin preferentially expressed in keratinocytes, has been implicated in wound healing and defective skin repair. Here we report using genetically-engineered mouse models and human samples, essential roles for Gal-7 during skin carcinogenesis via coordinated intracellular and extracellular mechanisms. Heightened Gal-7 expression delineated malignant lesions in non-melanoma skin cancer (NMSC) patients and shaped the course of skin carcinogenesis in mice. Intracellularly, increased Gal-7 conferred genomic instability to skin lesions and favored transcription of inflammation-related genes reprogramming the immune landscape toward a myeloid immunoregulatory profile. Extracellularly, Gal-7 accelerated skin carcinogenesis through glycan-dependent induction of monocytic myeloid-derived suppressor cells with enhanced immune regulatory activity. Our findings identify a lectin-driven molecular circuitry that promotes skin carcinogenesis by coupling genomic instability, transcriptional regulation and myeloid immunosuppressive programs, suggesting a potential therapeutic target for the treatment of NMSC.

Project description:Cutaneous squamous cell carcinoma (cSCC) is the most prominent tumor of non-melanoma skin cancers and the most aggressive tumor among keratinocyte carcinoma of the skin, showing a high potential for local invasion and metastasis. The cSCC incidences increased dramatically in recent years and the disease occurs more commonly than any other malignancy. The secretome of cancer cells is currently the focus of many studies in order to identify new marker proteins for different types of cancer and to investigate its influence on the tumor microenvironment. In our study we evaluated whether the secretome of cSCC cells has an impact on keratinocytes, the surrounding tissue cells of cSCC. Therefore, we analyzed and compared the secretome of human A431 cancer cells and of HaCaT keratinocytes by mass spectrometry.

Project description:Human papillomavirus type 8 (HPV8) is associated with the development of non-melanoma skin cancer. In the past we already delved into the mechanisms involved in keratinocyte invasion, showing that the viral E7 oncoprotein is a key player that drives invasion of basal keratinocytes controlled by the extracellular protein fibronectin. To unravel further downstream effects in E7 expressing keratinocytes we now characterized alterations of the phospho-proteome in E7 expressing N/TERT keratinocytes.

Project description:Melanoma is a very aggressive type of skin cancer, which renders it difficult to treat because of extensive heterogeneity frequently observed in melanoma tumours. Here we hypothesized that gene expression and DNA methylation differences would correlate with invasiveness in melanoma cells. To address this question, we carried out genome-wide transcriptome and methylome investigations in non-invasive and invasive groups of melanoma cell lines.
