The recessive form of dystrophic epidermolysis bullosa (RDEB) is a crippling disease caused by impairments in the junctions of the dermis and the basement membrane of the epidermis. Using ectopic expression of hTERT/hTERT + BMI-1 in primary cells, we developed expansible cultures of RDEB fibroblasts and keratinocytes. We showed that they display the properties of their founders, including morphology, contraction ability and expression of the respective specific markers including reduced secretion of type VII collagen (C7). The immortalized keratinocytes retained normal stratification in 3D skin equivalents. The comparison of secreted protein patterns from immortalized RDEB and healthy keratinocytes revealed the differences in the contents of the extracellular matrix that were earlier observed specifically for RDEB. We demonstrated the possibility to reverse the genotype of immortalized cells to the state closer to the progenitors by the Cre-dependent hTERT switch off. Increased β-galactosidase activity and reduced proliferation of fibroblasts were shown after splitting out of transgenes. We anticipate our cell lines to be tractable models for studying RDEB from the level of single-cell changes to the evaluation of 3D skin equivalents. Our approach permits the creation of standardized and expandable models of RDEB that can be compared with the models based on primary cell cultures.

The expression of the cell-cell adhesion molecules E- and P-cadherin has been analyzed in seven mouse epidermal keratinocyte cell lines representative of different stages of epidermal carcinogenesis. An inverse correlation between the amount of E-cadherin protein and tumorigenicity of the cell lines has been found, together with a complete absence of E-cadherin protein and mRNA expression in three carcinoma cell lines (the epithelioid HaCa4 and the fibroblastoid CarB and CarC cells). A similar result has been detected in tumors induced in nude mice by the cell lines, where induction of E-cadherin expression takes place in moderately differentiated squamous cell carcinomas induced by HaCa4 cells, although at much lower levels than in well-differentiated tumors induced by the epithelial PDV or PDVC57 cell lines. Complete absence of E-cadherin expression has been observed in spindle cell carcinomas induced by CarB or CarC cells. P-cadherin protein was detected in all cell lines that exhibit an epithelial (MCA3D, AT5, PDV, and PDVC57) or epithelioid (HaCa4) morphology, as well as in nude mouse tumors, independent of their tumorigenic capabilities. However, complete absence of P-cadherin was observed in the fibroblast-like cells (CarB and CarC) and in spindle cell carcinomas. The introduction of an exogenous E-cadherin cDNA into HaCa4 cells, or reactivation of the endogenous E-cadherin gene, leads to a partial suppression of the tumorigenicity of this highly malignant cell line. These results suggest a role for E-cadherin in the progression to malignancy of mouse epidermal carcinogenesis. They also suggest that the loss of both E- and P-cadherin could be associated to the final stage of carcinogenesis, the development of spindle cell carcinomas.

Inflammation is a central aspect of tumour biology and can contribute significantly to both the origination and progression of tumours. The NFκB pathway is one of the most important signal transduction pathways in inflammation and is, therefore, an excellent target for cancer therapy. In this work, we examined the influence of four NFκB inhibitors—Cortisol, MLN4924, QNZ and TPCA1—on proliferation, inflammation and sensitisation to apoptosis mediated by the death ligand FasL in the HNSCC cell lines PCI1, PCI9, PCI13, PCI52 and SCC25 and in the human dermal keratinocyte cell line HaCaT. We found that the selection of the inhibitor is critical to ensure that cells do not respond by inducing counteracting activities in the context of cancer therapy, e.g., the extreme IL-8 induction mediated by MLN4924 or FasL resistance mediated by Cortisol. However, TPCA1 was qualified by this in vitro study as an excellent therapeutic mediator in HNSCC by four positive qualities: (1) proliferation was inhibited at low μM-range concentrations; (2) TNFα-induced IL-8 secretion was blocked; (3) HNSCC cells were sensitized to TNFα-induced cell death; and (4) FasL-mediated apoptosis was not disrupted.
