(Submitter supplied) In epidermis, granular keratinocytes are responsible for the synthesis of a great number of proteins of high tissue-specificity, and required for the epidermal barrier establishment and the regulation of the desquamation process. This project aims at characterizing the physiopathological function of genes implicated in these processes, and in the short term, defining their expression level in the course of keratinocyte differentiation. more...

(Submitter supplied) Acute expression of E7 oncogene from HPV-16 or HPV-18 is sufficient to overcome tumor necrosis factor-alfa (TNF) cytostatic effect on primary human keratinocytes. In the present study we investigated the molecular basis of E7-induced TNF resistance through a comparative analysis of the effect of this cytokine on the proliferation and global gene expression of organotypic cultures of normal and E7(wild type or mutant)-expressing keratinocytes.

(Submitter supplied) DNA microarray technology is a powerfull tool for genome-wide gene expression analysis of biological samples. Here we review the methodology for expression profiling analysis of skin tissue or purified keratinocytes from mice. We explained the methodology and protocols for RNA preservation and purification, RNA quality and integrity tests, and DNA microarray technology types that can be used. Furthermore, using a dataset of mice samples, we explained how to perform chip raw data preprocessing and normalization, differential expression analysis, as well as gene-clustering and funcional analysis of gene deregulation. more...

(Submitter supplied) Primary HBE cells were stimulated with IL-22 and IL-17, and gene expression was studied using an Affymetrix platform microarray, in order to investigate which genes may be upregulated or downregulated in response to these cytokines. Of particular interest was the host defense genes such as antimicrobial peptides, which have been shown to be upregulated by IL-22 and IL-17 in skin keratinocytes. Keywords: cytokine effect

Analysis of bronchial epithelial cells treated with interleukin (IL)-22, IL-17, or both. IL-17 receptor mutant lungs are susceptible to Klebsiella pneumonia infections. IL-22 induces antimicrobial peptide expression. Results provide insight into the extent of IL-22 and IL-17's role in host defense.

(Submitter supplied) The analysis of differentially expressed genes is a powerful approach to elucidate the genetic mechanisms underlying the morphological and evolutionary diversity among serially homologous structures, both within the same organism (e.g., hand vs. foot) and between different species (e.g., hand vs. wing). In the developing embryo, limb-specific expression of Pitx1, Tbx4, and Tbx5 regulates the determination of limb identity. more...

(Submitter supplied) APOE4 allele is a major risk factor for late-onset Alzheimer disease (AD). The mechanism of action of APOE in AD remains unclear. To study the effects of APOE alleles on gene expression in AD, we have analyzed the gene transcription patterns of human hippocampus from APOE3/3, APOE3/4, APOE4/4 AD patients and normal control using Serial Analysis of Gene Expression (SAGE). Using SAGE, we found gene expression patterns in hippocampus of APOE3/4 and APOE4/4 AD patients differ substantially from those of APOE3/3 AD patients. more...

(Submitter supplied) Skin carcinogenesis is known to be a multi-step process with several stages along its malignant evolution. We hypothesized that transformation of normal epidermis to cutaneous squamous cell carcinoma (cSCC) is causally linked to alterations in miRNA expression. For this end we decided to evaluate their alterations in the pathologic states ending in cSCC. Total RNA was extracted from FFPE biopsies of five stages along the malignant evolution of keratinocytes towards cSCC: Normal epidermis, severe solar elastosis (SE), actinic keratosis (KIN1-2), advanced actinic keratosis, (KIN3) and well differentiated cSCC. more...

(Submitter supplied) We found that miR-497 expression decrease in cSCC biopsies and cell lines compare to normal skin biopsies or normal keratinocytes cell. To understand in role lost expression of miR-497 might have in tumorigenesis of keratinocytes, we aimed to fine possible biochemical pathways and possible targets of miR-497 in cSCC. In order do so, we over expressed miR-497 in cSCC and used microarrays to fine global gene expression effected by miR-497.

(Submitter supplied) In this study we examine the outcomes of p16INK4a activation in the adult epidermis. We found that prolonged expression of p16INK4a induces epidermal hyperplasia and dysplasia. We also found that continued p16INK4a expression increased the number of epidermal papillomas that developed after carcinogen treatment. Profling of p16INK4a- expressing cells showed elevated levels of Wnt-pathway ligands and targets, and pharmacologic or genetic Wnt inhibition suppressed p16-induced hyperplasia. more...

(Submitter supplied) To obtain a separation of the epidermal and dermal compartments in order to examine compartment specific biological mechanisms in the skin we incubated 4 mm human skin punch biopsies in ammonium thiocyanate (NH4SCN). We wanted to test 1) the histological quality of the dermo-epidermal separation obtained by different incubation times 2) the amount and quality of extractable epidermal RNA, and 3) its impact on sample RNA expression profiles assessed by large-scale gene expression microarray analysis in both normal and inflamed skin. more...
