RNA-Seq whole transcriptome analysis of normal human epidermal keratinocytes and cutaneous squamous cell carcinoma cell lines.

ABSTRACT: 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.

Keratinocyte-derived skin cancer, cutaneous squamous cell carcinoma (cSCC), is the most common metastatic skin cancer. We have examined the role of Eph/ephrin signaling in the progression of cSCC. Analysis of the expression of EPH and EFN families in cSCC cells and normal epidermal keratinocytes revealed overexpression of EPHB2 mRNA in cSCC cells and cSCC tumors in vivo. Tumor cell-specific overexpression of EphB2 was detected in human cSCCs and in chemically induced mouse cSCCs with immunohisto ...[more]

Analysis of the gene expression profile in cutaneous squamous cell carcinoma cells after EphB2 knockdown

Project description:The role of Eph/ephrin signaling in numerous biological processes has been established. However, Eph/ephrin signaling has been shown to have complex role in tumor progression. The role of EphB2 receptor in the progression of cutaneous squamous cell carcinoma (cSCC) has not been studied before. EphB2 is significantly overexpressed in cSCC cells compared with normal human epidermal keratinocytes (NHEKs). We used microarray based global gene expression profiling to study the effect of EphB2 knockdown on the expression of different genes in cSCC cells. cSCC cell lines (n=3) were transfected with either control or EphB2 siRNA (75 nM) and incubated for 72 hours. Total RNA was extracted and processed expression profiling with GeneChip 3’ IVT Express Kit according to manufacturer’s protocol.

RNA-Seq analysis of cSCC cells followed by siRNA-induced gene knockdown of AIM2.

Project description:Keratinocyte-derived cutaneous squamous cell carcinoma (cSCC) is the most common metastatic skin cancer, and its incidence is increasing globally. Chronic inflammation has been recognized as a risk factor for cSCC and inflammation is a typical feature of the progression of actinic keratosis lesions to invasive and metastatic cSCC. Inflammasomes are important components of the innate immune response involved in onset of inflammation. Inflammasome component AIM2 serves as a sensor for cytoplasmic double-strand DNA, and this way plays a key role in response to bacterial and viral colonization. Activation of inflammasome by cytoplasmic DNA in epidermal keratinocytes can promote the initiation of inflammation in autoimmune and autoinflammatory skin diseases. Whole transcriptome analysis of cSCC cells (n=8) and normal human epidermal keratinocytes (NHEKs, n=4) and oligonucleotide array-based expression analysis of cSCC cells (n=8) and normal human epidermal keratinocytes (NHEKs, n=5) revealed overexpression of AIM2 in cSCC cells (GSE66412 and GSE66368, respectively). We wanted to futher study the RNA expression profile of AIM2 knockdown cSCC cells.

mRNA-Seq analysis of cSCC cells followed by siRNA-induced gene knockdown of CFI.

Project description:Keratinocyte carcinomas (BCC and cSCC) are the most common cancers worldwide. cSCC is considered as the most prevalent metastatic skin malignancy and its incidence is increasing globally. The complement system is a fundamental part of the host immune defense. It is composed of three distinct pathways (classical, alternative and lectin) that get activated sequentially. However, the process of complement activation is rigorously regulated by a series of soluble and membrane-bound inhibitor proteins that protect the host cells from lytic damage. One of these soluble negative regulators is complement factor I (CFI) which is an 88 kDa serine protease that hampers all three complement pathways through blockade of C3- and C5- convertases by cleaving C3b and C4b. Oligonucleotide array (Affymetrix)-based analysis of normal human epidermal keratinocytes (NHEKs; n=5), primary (Prim. cSCC; n=5) and metastatic (Met. cSCC; n=3) cSCC cell lines as well as next-generation-sequencing (SOLiD) based transcriptome profiling of NHEKs (n=4), primary (Prim. cSCC; n=5) and metastatic (Met. cSCC; n=3) cSCC cell lines revealed marked overexpression of CFI in cSCC cells compared to NHEKs (GSE66368 and GSE66412 respectively). Furthermore, we have previously shown that knockdown of CFI inhibits proliferation and migration of cSCC cells and potently impedes growth of cSCC xenograft tumors in vivo. In these respects, we intended to further investigate the functional role and molecular mechanism of CFI in cSCC progression via analyzing the mRNA expression profile of CFI in cSCC cells.

RNA-Seq analysis of cSCC cells followed by siRNA-induced gene knockdown of C1s.

Project description:Keratinocyte-derived cutaneous squamous cell carcinoma (cSCC) is the most common metastatic skin cancer, and its incidence is increasing globally. Chronic inflammation has been recognized as a risk factor for cSCC and inflammation is a typical feature in the progression of premalignant actinic keratosis lesions to invasive and metastatic cSCC. The complement system is an important part of innate immunity, and activation of complement is detected in the microenvironment of tumors and has been considered a host defense mechanism against cancer cells. The complement cascade can be activated via three distinct pathways, namely the classic, lectin, or alternative pathways, which all lead to activation of lytic pathway and formation of the membrane attack complex, a pore-like structure on the target cell membrane resulting in the lysis of the target cell. The classical pathway of complement is typically activated by binding of C1 complex to antibodies bound to their target antigens. The C1 complex consists of six subcomponents of C1q, each with a collagenous triple helix of subunits C1qA, C1qB, and C1qC chains and two copies of serine proteases C1r and C1s subunits each. Whole transcriptome analysis of cSCC cells (n=8) and normal human epidermal keratinocytes (NHEKs, n=4) and oligonucleotide array-based expression analysis of cSCC cells (n=8) and normal human epidermal keratinocytes (NHEKs, n=5) revealed overexpression of C1s in cSCC cells (GSE66412 and GSE66368, respectively). Inthis respect, we have wanted to futher study the RNA expression profile of C1s knockdown cSCC cells.

Differentiation-related epigenomic changes define clinically distinct keratinocyte cancer subclasses

Project description:Keratinocyte cancers (KC) are the most prevalent malignancies in fair-skinned populations, posing a significant medical and economic burden to health systems. KC originate in the epidermis and mainly comprise basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC). Here, we combined single-cell transcriptomics, methylomics and multi-omics to investigate the epigenomic dynamics during epidermal differentiation. We identified ~4,000 differentially accessible regions between undifferentiated and differentiated keratinocytes, corresponding to regulatory regions associated with key transcription factors. DNA methylation at these regions defined AK/cSCC subtypes with epidermal stem cell- or keratinocyte-like features. Using cell type deconvolution tools and integration of bulk and single-cell methylomes, we demonstrate that these subclasses are consistent with distinct cells-of-origin. Further characterization of the subclasses with an epigenetic mitotic-like clock, and the study of other unstratified KC entities uncovered distinct phenotypic and clinical features for the subclasses, linking invasive and metastatic KC cases with undifferentiated cells-of-origin. Our study provides a thorough characterization of the epigenomic dynamics underlying human keratinocyte differentiation and uncovers novel links between KC cells-of-origin and their prognosis
