Identify the effects of miR-19a-3p miRNA mimic overexpression in mouse calvarial osteoblast primary cultures

ABSTRACT: We used a primary calvarial osteoblast cell line (CalOB) to transfect either a negative control or miR-19a-3p miRNA mimic to understand the effects on global gene expression using bulk RNA-seq.

Transcription profiling of juvenile and adult calvarial bone

Project description:Background: It has widely been observed that young children are capable of reossifying large calvarial defects, while adults lack this endogenous tissue-engineering capacity. The ability of juvenile animals to regenerate calvarial defects has been investigated in multiple animal models, including mice. In this study, the authors used cDNA microarrays to investigate the expression of osteogenesis-associated genes upstream and downstream of Runx2 in juvenile and adult mouse calvaria. Methods: Nonsuture-associated parietal bone discs were harvested from 6-day-old (n = 50) and 60-day-old (n = 35) male CD-1 mice. After separation of the underlying dura mater and overlying pericranium, the calvarial discs were snap-frozen and RNA was extracted from pooled samples of calvaria for microarray analysis. Genes analyzed included cytokines, receptors, and cell-surface and matrix proteins both upstream and downstream of Runx2. Results: Genes associated with the Runx2 pathway had notably higher levels in the juvenile versus adult calvaria. All genes except for osteocalcin were expressed at least twofold higher in the juvenile calvaria. This pattern was validated with quantitative real-time polymerase chain reaction. In addition, mRNA for potent osteoinductive growth factors was present at higher levels in the juvenile compared with the adult calvaria. Conclusions: These findings reflect a genomic environment of active osteoblast differentia-tion and ossification in the juvenile calvaria compared with the adult aquiescent calvarial tissue. These data suggest that a decreased osteogenic potential of adult calvarial osteoblasts may, in part, explain the inability of adult animals to heal calvarial defects.

The global gene expression profile of gain of function miR34c in osteoblast

Project description:To examine the unbiased global gene expression of gain of miR34c in committed osteoblast in mouse we have performed expression microarray. This approach will allow us to define the novel targets that are negatively regulated by over-expression of miR34c in osteoblast. Total RNA was isolated from primary calvaria from WT and GOF miR34c mouse (n=3) at the age of P3. WT primary calvarial samples were served as control.

Sp7/Osterix is restricted to bone-forming vertebrates where it acts as a Dlx co-factor in osteoblast specification [RNA-Seq]

Project description:Sp7/Osterix is a master regulator of osteoblast specification. To identify transcripts profile in Sp7 positive osteoblast, we performed RNA-seq on primary mouse calvarial cells obtained from Sp7-GFP reporter mice at P1. By hierarchical clustering using transcriptional profiles for chondrocytes and mouse embryonic fibroblasts (MEFs) together with the osteoblast data, we identified cell-type enriched gene expression signatures in osteoblasts, chondrocytes and MEFs. In conjunction with Sp7 ChIP-seq in osteoblast, we identified putative Sp7 targets which underlie the osteoblast regulatory program.

Osteoblast Gene Expression in Response to Bicc1 Knockdown

Project description:We recently identified Bicc1 as a regulator of osteoblast differentiation and bone mass. Bicc1 encodes an RNA-binding protein. Here, we have used siRNA to decrease Bicc1 expression in primary calvarial osteoblasts. Illlumina microarrays were then used to profile global gene expression changes. The experiment consisted of 16 total samples in 4 treatment groups (N=4 replicates per treatment). The treatment groups were osteoblasts treated with 1). control scrambled siRNA, 2) Bicc1_1 siRNA, 3) Bicc1_2 siRNA and 3) Bicc1_3 siRNA. Cells were isolated, transfected and 48 hours later RNA was isolated and hybridized to arrays.

Expression data from human osteoblast cultures

Project description:Studies in Aotearoa New Zealand found higher bone mineral density and lower rate of hip fracture in people of Polynesian ancestry compared to Europeans. We hypothesised that differences in osteoblast gene expression contribute to the differences in bone properties between the two groups, and aimed to identify mechanisms that underlie the bone phenotype.

mRNA expression changes in miR-19a treated cells

Project description:The goal of the subject is to explore the changed expression mRNA after miR-19a is knockdown. We transfected Hepatocelluar carcinoma cell line (Huh7) with control vector or miR-19a inhibitor and got a stable cell line. Then we screened the mRNA expression and found the changed genes.

Sp7/Osterix is restricted to bone-forming vertebrates where it acts as a Dlx co-factor in osteoblast specification [ChIP-Seq]

Project description:Sp7/Osterix is a master regulator of osteoblast specification. To identify the Sp7-mediated gene regulatory network in osteoblasts, we performed Sp7 ChIP-seq on primary mouse calvarial osteoblasts comparing the DNA binding profile with the transcriptional profile of Sp7-positive osteoblasts. Analysis of these identified a network of Sp7 regulated osteoblast targets and provides a new insight into the mode of Sp7 action in osteoblast. To further study for the Sp7 mode, we performed ChIP-seq for Sp1, Sp7, Dlx5, as a potential Sp7 partner identified in this study and mutated Sp7 which has mutations in the zinc finger domain, by using in vitro system with a pre-osteoblast mouse cell line, MC3T3E1.
