Project description:Investigation of gene expression in human skin keratinocytes (HaCaT) following non-thermal plasma treatment for 20 s, 60 s, and 180 s compared to untreated and H2O2-treated controls. Microarrays were used to analyze and investigate the biological effects of non-thermal plasma on human keratinocyte cells. Using an argon plasma jet kinpen, regulated transcripts were analyzed and further described in Schmidt et al. (2014): “Transcript profiling identifies an important role for Nrf2/Keap1-pathway after non-thermal plasma treatment in human keratinocytes”.

Project description:Investigation of gene expression in cultured human skin epithelial keratinocytes (HaCaT) following non-thermal plasma treatment for 60 s, compared to untreated control. Non-thermal atmospheric pressure plasma has recently gained attention in the field of biomedical and clinical applications. In the area of plasma medicine research one promising approach is to promote wound healing by stimulation of cells involved. To understand basic molecular and cellular mechanisms triggered by plasma treatment we investigated biological effects of an argon plasma jet (kinpen) on human epithelial skin cells. Consequently, whole-genome microarrays were used to analyze this interaction in detail and identified a statistically significant modification of 3,274 genes including 1,828 up- and 1,446 down-regulated genes. Particularly, plasma-treated cells are characterized by differential expression of a considerable number of genes involved in the response to stress. In this regard, we found a plasma-dependent regulation of oxidative stress answer and increased expression of enzymes of the antioxidative defense system (e.g. 91 oxidoreductases). Our results demonstrate that plasma induces cell reactions of stress-sensing but also of proliferative nature. Consistent with gene expression changes as well as Ingenuity Pathway Analysis prediction, we propose that stimulating doses of plasma may protect epithelial skin cells in wound healing by promoting proliferation and differentiation. In conclusion, gene expression profiling may become an important tool in identifying plasma-related changes of gene expression. Our results underline the enormous clinical potential of plasma as a biomedical tool for stimulation of epithelial skin cells We investigated biological effects of an argon plasma jet on HaCaTs. Microarray were used to analyzed this interaction in detail. The transcripts analyzed in this study are further described in Schmidt et al.

Project description:We have sequenced miRNA libraries from human embryonic, neural and foetal mesenchymal stem cells. We report that the majority of miRNA genes encode mature isomers that vary in size by one or more bases at the 3’ and/or 5’ end of the miRNA. Northern blotting for individual miRNAs showed that the proportions of isomiRs expressed by a single miRNA gene often differ between cell and tissue types. IsomiRs were readily co-immunoprecipitated with Argonaute proteins in vivo and were active in luciferase assays, indicating that they are functional. Bioinformatics analysis predicts substantial differences in targeting between miRNAs with minor 5’ differences and in support of this we report that a 5’ isomiR-9-1 gained the ability to inhibit the expression of DNMT3B and NCAM2 but lost the ability to inhibit CDH1 in vitro. This result was confirmed by the use of isomiR-specific sponges. Our analysis of the miRGator database indicates that a small percentage of human miRNA genes express isomiRs as the dominant transcript in certain cell types and analysis of miRBase shows that 5’ isomiRs have replaced canonical miRNAs many times during evolution. This strongly indicates that isomiRs are of functional importance and have contributed to the evolution of miRNA genes
