Project description:Detection of tRNA-derived fragments (tRFs) in HaCaT cells under normal growth conditions without treatment
2018-12-09 | GSE119765 | GEO
Project description:Aim of the study was to characterize at a molecular level (changes in transcriptomes) the effect of monosodium urate crystal (MSU) on HaCaT keratinocyte cell line. This was adressed by using a culture model. The HaCaT cell line (human keratinocytes) was stimulated by MSU (1mg/mL) vs control for 12 hrs. By using genome-wide expression profiling, we identified deregulation of functionally relevant gene networks. HaCaT were obtained from Cell Lines Service (Eppelheim, Germany) and grown in DMEM medium (PAN biotech, Aidenbach, Germany) supplemented with 10% FBS (Life Technology, Grand Island, NY, USA), L-glutamine and non-essential amino acid. Before the treatment HaCaT cells were cultured in serum-free medium for 12hrs. HaCaT were treated with MSU (1mg/ml) vs DMEM control for 12hrs then submitted to RNA extration and gene expression profiling. Triplicate experiments were performed: HaCaT control (n=3), MSU-treated (n=3).

Project description:The specific functional features of the epidermal keratinocytes are determined by the activity of many genes. The aim of the project was to characterize the role of HSPA2, a member of the HSPA chaperone family (HSP70), in human epidermal keratinocytes. The downregulation of HSPA2 gene in HaCaT cell line was performed by lentivirus-mediated shRNA method. Next, the effect of modifications on the transcriptomic profile of cells growing in a three-dimensional model of reconstructed human epidermis in vitro was investigated. The cells were grown at air-liquid interface culture on extracellular matrix to achieve maximal level of HaCaT differentiation in RHE system. This study was supported by a Polish National Science Center grant number NCN 2017/25/B/NZ4/01550.

Project description:We transfected keratinocytes cell line (HaCaT cells) with si-NC and si-eIF4E, and added M5 into the cell culture medium to reveal the function of eIF4E in the in vitro psoriasis cell model.

Project description:tRNA-derived fragments (tRFs) are new noncoding RNAs, and recent studies have shown that tRNAs and tRFs have important functions in cell metabolism via posttranscriptional regulation of gene expression. However, whether tRFs regulate cellular metabolism of the anterior cruciate ligament (ACL) remains elusive. The aim of this study was to investigate the role and action mechanism of tRFs in ACL cell metabolism. Arraystar_tRF&tiRNA was used to determine tRFs and tiRNA expression profiles in human OA ACL cells and NA ACL cells。

Project description:The p53 protein is encoded by TP53 gene and plays the key role in significant number of cellular processes including proliferation, apoptosis and regulation of many stress response pathways. P53 acts like a direct transcription activator of numerous genes regulating cell cycle arrest, DNA repair, growth inhibition and many others (Mollereau and Ma, 2014). The canonical biological function of p53 is maintaining genome integrity via elimination of damaged or exposed to genotoxic stress cells. Immortalized HaCaT cells are widely used for keratinocyte research, since they maintain stable keratinocyte phenotype, have nearly unlimited proliferative potential, do not require specific growth and differentiation factors (Colombo et al., 2017). Also, HaCaT cells produce typical differentiation markers such as cytokeratins K14 and K10, involucrin (Colombo et al., 2017) and respond to keratinocyte differentiation stimuli. Taking together, HaCaT cells have similar to normal human keratinocytes (NHK) properties, however, as many of spontaneously immortalized cell lines HaCaT cells bear two mutant p53 alleles - R282Q and H179Y (Lehman et al., 1993). Mutp53 in HaCaT has an increased affinity to other p53 family members (p63, p73), which significantly expands p53 properties. Moreover, mutp53 indirectly affects specific target genes via protein-protein interactions with other transcription factors (NF-Y, E2F1, NF-KB) or by tethering p63 to new promotor locations. For more detailed investigation of mutp53 impact on various processes in HaCaT cells we performed a shRNA mediated knockdown of mutp53. For generation of stable TP53 knockdown we employed plasmid vector pLKO-p53-shRNA-941 (Addgene # #25637) followed by puromycin selection of transduced cells. Here we present proteomic dataset obtained from wild type HaCaT cells and p53 knock down HaCaT keratinocytes.

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:The purpose of this study is to search for aberrant genes in HaCaT keratinocytes after chronic exposure to arsenic trioxide. The objective of the investigation was to discover the mechanism of arsenic carcinogenicity in human epidermal keratinocytes. We hypothesize that a combined strategy of DNA microarray, qRT-PCR and gene function annotation will identify aberrantly expressed genes in HaCaT keratinocyte cell line after chronic treatment with arsenic trioxide. HaCaT cells were chronically exposed to 0.5M-BM-5g/mL arsenic trioxide (As2O3) up to 22 passages and RNA was extracted. Microarray data analysis identified 14 up-regulated genes and 21 down-regulated genes in response to arsenic trioxide Two experimental groups: 1. The treatment group was sub-cultured up to passage 22 to establish a chronic exposure state. 2. The passage control group was also sub-cultured up to 22 passages but with no exposure to arsenic trioxide. 4 technical replicates with 3 replicates making a total of 8X3 =24 samples HaCat Cell untreated (passage control): 1. H1_H001, H1_H002, H1_H003 2. H2_ H004, H2_H005, H2_H006 3. H3_ H007, H3_H008, H3_H009 4. H4_ H010, H4_H011, H4_H012 HaCat Cell treated with 0.5M-BM-5g/ml of arsenic trioxide: 5.

A4_H022, A4_H023, A4_H024 Cell Type: Human Skin Keratinocyte: 1.5 M-CM-^W105 HaCaT cells were cultured in 7.5 ml of complete DMEM containing 10% Fetal Bovine Serum (FBS) and 1% penicillin, streptomycin in T-25 culture plate. Cells were incubated in a humidified atmosphere with 5% CO2 at 37 M-BM-:C. The treatment groups were exposed to 0.5M-BM-5g/mL As2O3 (equivalent to LC 0.5), and passaged at 90% confluent. Total RNA was extracted from 4 technical replicates of unexposed HaCaT cells and HaCaT cells chronically exposed to arsenic trioxide up to passage 22 using RNA STAT-60 (TEL-TEST, INC, Friendswood, TX, USA).
