Project description:In humans, vitamin D3 is a secosteroid, a prohormonal precursor of biologically active hydroxyforms. Vitamin D3 is related to periodontitis. The third American Health and Nutrition Survey found that plasma 25(OH)D3 levels are negatively correlated with attachment loss in people aged >50 years. The relationship between vitamin D3 and periodontitis remains to be investigated. We sent human gingival fibroblasts treated by vitamin D3 for transcriptome sequencing.

Project description:Transcriptional profiling of pass 2 primary human gingival fibroblasts (GF) comparing control untreated GF with GF treated with LPA 18:1 for 2h or 8h. The goal of this study was to determine the effects of LPA 18:1 on global GF gene expression.

Project description:We wanted to examine the effect of vitamin D3 and endogenous mutant p53 expressed in SKBR3 cells on gene expression paterns. Expression microarray analysis was performed on SKBR3 cells without or with endogenous mutp53 knockdown, with or without 1a25-vitamin D3 treatment.

Project description:Transcriptional profiling of pass 2 primary human gingival fibroblasts (GF) comparing control untreated GF with GF treated with LPA 18:1 for 2h or 8h. The goal of this study was to determine the effects of LPA 18:1 on global GF gene expression. Three-condition experiment, GF vs. LPA-treated (2h, 8h) GF cells. Biological replicates: 3 control replicates, 3 LPA-treated replicates.

Project description:Fibroblasts are widely used cells for regenerative medicine in clinics, such as gingival or facial skin treatment. In fact, fibroblasts are considered as a mixture of various types of cells with "spindle shape" and there is no available clear marker. Gingival and dermal fibroblasts are similar in their morphology and function; however it is considered that the cultured cells retain their original characteristics depending on the origin, which may contribute to the differential therapeutic effects. For example, gingival wounds are known to heal relatively quickly with less scar formation compared with skin, which may imply their higher capability for regeneration as a therapeutic effect. The reason for this phenomenon may be partly due to characteristic differences between gingival and dermal fibroblasts including the expression of migration stimulating factor and matrix formation but these differences remain largely unknown. Recently, the characteristics of dermal fibroblasts have been reported to be different depending on body sites, such as face, trunk and plamoplantar skin. Although the expression of fibronectin and their splicing variants were known to be different between trunk and oral mucosal fibroblasts, there is still no detailed report on the functional differences between gingival and dermal fibroblasts. In this study, we investigated differential gene expression in normal gingival and dermal fibroblasts using DNA microarray to investigate the difference between the vague fibroblast-type cells from different tissue origin to achieve higher therapeutic effect in cell therapy.

In this study, we investigated differential gene expression in normal gingival and dermal fibroblasts using DNA microarray to investigate the difference between the vague fibroblast-type cells from different tissue origin to achieve higher therapeutic effect in cell therapy. Gingival and dermal tissues were collected from healthy patients. After successive stages primary culture and RNA extraction and hybridization on Affymetrix microarrays (Genome Focus Array). Dermal and gingival tissues were obtained from healthy volunteers (8 cases for dermal tissue; 6 females, 2 males , average age 48 and 8 cases for buccal gingival tissue; 6 females, 2 males, average age 43) whose informed consent was obtained according to a protocol approved by the ethics committee of Nagoya University Hospital. After enzymatic digestion, tissues were cultured in Dulbecco's modified Eagle's medium (DMEM) containing 10% fetal bovine serum at 37°C in the presence of 5% CO2 for about 4 weeks as reported previously. Total mRNAs were extracted from cells between passages 4-5 by Trizol reagent (Invitrogen, Carlsbad, CA, USA) and were applied to Human Focus Arrays (Affymetrix, Santa Clara, CA, USA) for microarray analysis according to the manufacturer's protocol (http://www.affymetrix.com/support/technical/manuals.affx). The gene expression data were analyzed by Arrayassist (Stratagene, La Jolla, CA, USA). Briefly, 8,500 probes on the array, normalization and scaling (MAS5), flag-positive gene selection, unpaired t-test, and CV selection (<20) resulted in 5,284 genes to analyze. GO (Gene ontology) analysis was performed using the software default settings to find the gene group related to the same category of biological function by searching common key terms that were reported for each gene.

Project description:Description: SMARCD1, an auxiliary subunit of the SWI/SNF complex is essential for maintaining embryonic stem cell pluripotency and metabolic gene regulation. Here, we have tried to address the role of SMARCD1 in myeloid differentiation and leukemia. To address this, we transduced HL60 cells with lentiviral particles expressing shcontrol and shSMARCD1. Next we subjected these cells to 10 nM vitamin D3 induction for 48 h. RNA-sequencing was conducted for shcontrol and shSMARCD1 in uninduced and vitamin D3 induced HL-60 cells. High quality RNA with RIN values above 9, was used to generate library using TruSeq™ stranded mRNA kit (20020595, Illumina) following manufacturer’s instructions. Finally barcoded libraries were pooled, and a final concentration of 1.2 pM was loaded using NextSeq 500/550 High Output Kit v2 150 Cycles (15057931, Illumia) and paired-end sequenced in a Nextseq 550 (Illumina).
