Project description:This RNA sequencing dataset analyzes circRNA expression changes in HaCaT keratinocytes after UVA irradiation. Cells were exposed to 5 J/cm2 UVA and profiled using ribosomal RNA-depleted RNA sequencing on an Illumina platform. Differentially expressed circRNAs were identified by computational pipelines. The data provide insights into circRNA regulation during photo-oxidative stress.
Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to compare transcriptome profiling (RNA-seq) between HaCaT cell and OSM-treated HaCaT cells Methods: mRNA profiles of HaCaT cells and OSM-treated HaCaT cells were generated by deep sequencing, in triplicate, using Illumina GAIIx. The sequence reads that passed quality filters were analyzed at the transcript isoform level with two methods: Burrows–Wheeler Aligner (BWA) followed by ANOVA (ANOVA) and TopHat followed by Cufflinks.
Project description:Transcriptome profiling by using RNA-seq was performed on bleogen pB1-treated, EGF-treated, and untreated HaCaT keratinocytes to gain further insights into the wound healing effects of bleogen pB1 and EGF
Project description:Obacunone treatment upregulates gene expression of cholesterol and lipid metabolism-associated genes in HaCaT cells Total RNA obtained from HaCaT cells treated with 10, 50, or 100 uM obacunoe for 4 h was compared to that of vehicle control cells.
Project description:Obacunone treatment upregulates gene expression of cholesterol metabolism-associated genes in HaCaT cells Total RNA obtained from HaCaT cells treated with 100 uM obacunone for 0.5, 1, 3, 6, or 12 h was compared to that of vehicle control cells.
Project description:Tissue resident macrophages play important roles in tissue homeostasis and acute response to external stimuli. Human skin equivalents (HSEs) incorporating human monocytic cell line THP-1, were fabricated to generate immunocompetent human skin models. These HSEs were used to investigate the influence of the skin microenvironment and UVA exposure on the phenotypes of macrophages. THP-1 in HSEs exhibited mixed M1 and M2 macrophage phenotypes. Transcriptomic analysis demonstrated that THP-1 in HSEs enriched extracellular matrix interaction while downregulated a DNA replication hallmark. Upon UVA exposure, immunocompetent HSEs exhibited epidermal distortion and increased DNA double-strand breaks (DSB). THP-1 isolated from UVA-exposed HSEs revealed significant upregulation of genes associated with oxidative stress, antioxidant regulation, inflammatory and UV response. A photoprotective agent, mycosporine-2-glycine (M2G), derived from cyanobacteria was applied on to immunocompetent HSEs and the responses of THP-1 cell line was investigated after UVA exposure. The result showed that UVA-induced DSB was significantly lower in M2G-treated HSEs. In addition, the inflammatory and UV response hallmarks were downregulated while the oxidative phosphorylation hallmark was upregulated in THP-1 from M2G-treated UVA exposed HSEs. Taken together, this study provides an immunocompetent 3D skin model that can be used to interrogate responses of skin resident innate immune cells to microenvironment and external stimuli such as UVA irradiation.
