Project description:Osteoblasts are responsive to shear stress. We investigated the effect of of laminar fluid flow (LFF) on osteoblast-like MC3T3-E1 cells at two timepoints. We used microarray analysis to detail the global gene expression of MC3T3-E1 cells in response to 1 hour of laminar fluid flow directly and 4 hours after treatment.
Project description:To identify the changes of mRNA expressions by PTH-treatment for 1 hr in mouse osteoblastic cell line MC3T3-E1, we performed RNA-sequencing (RNA-seq).
Project description:Microarray study revealed 1324 genes that were up-regulated and 1550 genes that were down-regulated more than 1.5 fold change (corrected p<0.05) in MC3T3-E1-derived-mature Osteoblasts compared to control MC3T3-E1.
Project description:Transcriptional profiling of MC3T3-E1 osteoblasts that were flow cytometry-separated from cocultures with control or Jagged1-overexpressing tumor cells and treated with either DMSO control or 1μM MRK-003 (gamma-secretase inhibitor). One cell line (MC3T3-E1) cells: four different experimental conditions: cultured with (1) control tumor cells + DMSO; (2) Jagged1-overexpressing tumor cells + DMSO; (3) control tumor cells + MRK-003; (4) Jagged1-overexpressing tumor cells + MRK-003. Each experiment has two biological replicates. Total, 8 samples.
Project description:To explore the mechanism by which osteoblastic 11β-HSD1 regulates bone formation and glucose handling, we transfected the mouse MC3T3-E1 osteoblastic cells with a plasmid carrying the exogenous Hsd11b1 or EGFP gene to construct the 11β-HSD1-overexpressed and control osteoblastic cells (hereafter MC3T3-HSD1 and MC3T3-GFP cells), respectively. After incubating with 11-DHC,we then employed RNA sequencing (RNA-seq) to examine the gene expression profile between MC3T3-HSD1 and MC3T3-GFP cells.

Project description:Purpose: This is a post-GWAS functional study that aims to determine the effect of Akap11 knockout in mouse preosteoblastic cell line MC3T3-E1 during osteogenesis. Methods: mRNA profile of WT (treated with CRISPR and remains unedited) and Akap11 knockout MC3T3-E1 cells were generated by RNAseq from pooled RNA (from 3 biological triplicate at equal quantity) of various timepoint during osteogenesis (Day 0, 7,16, 25).100ng total RNA was used for library construction by KAPA Stranded mRNA-Seq Kit (Roche). Pair-End 101bp sequencing was performed in the Illumin HiSq1500 sequencer using the HiSeq SBS Kit v4 (Illumina). Data was collected with SCS version 1.4.8. Base calling was performed using Illumina’s RTA (Version 1.12.4.2). 7 samples were sequenced per lane and achieved a sequencing depth of ~65 million read per sample. Results: Expression of osteogentic markers in Akap11 knockout MC3T3-E1 cells were suppressed. Genes invovled in IGF-I signaling pathway were signficantly altered.
