Iron excess limits HHIPL2 gene expression and decreases osteoblastic activity in human MG-63 cells

ABSTRACT: Our transcriptomic data shows that iron impact on human osteoblastic MG-63 cells by decreasing HHIPL-2 gene expression (2 fold ratio). This impact is corrected in presence of deferoxamine. Additional biological experiments in the manuscript suggest that the iron related modulation of HHIPL-2 gene expression could take place in the decrease of osteoblastic markers in the MG-63 cell line. Such mechanisms could participate to the development of osteoporosis in iron overloaded patients.

This impact is corrected in presence of deferoxamine. Additional biological experiments in the manuscript suggest that the iron related modulation of HHIPL-2 gene expression could take place in the decrease of osteoblastic markers in the MG-63 cell line. Such mechanisms could participate to the development of osteoporosis in iron overloaded patients. One-condition experiment, iron exposure using ferric ammonium citrate (FAC) at two concentrations (5 and 20M-BM-5M) was compared to basal condition. Additional conditions include: deferoxamine (DFO) (iron chelator) 20M-BM-5M alone or in addition to FAC 20M-BM-5M. For each condition five biological replicates were performed (independent experiments).

Effects of Hsd11b1 overexpressing in mc3T3-e1 pre-osteoblastic cell lines under glucocorticoid excess

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.

Effects of Hsd11b1 overexpressing in mc3T3-e1 pre-osteoblastic cell lines under glucocorticoid excess (ATAC-Seq)

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 assay for transposase-accessible chromatin with sequencing (ATAC-seq) to examine the gene expression profile between MC3T3-HSD1 and MC3T3-GFP cells.

Microgravity triggers ferroptosis and accelerates senescence in the MG-63 cell model of osteoblastic cells.

Project description:In space, cells sustain strong modifications of their mechanical environment. Mechanosensitive molecules at the cell membrane regulate mechanotransduction pathways that induce adaptive responses through the regulation of gene expression, post-translational modifications, protein interactions or intracellular trafficking, among others. In the current study, human osteoblastic cells were cultured on the ISS in microgravity and at 1 g in a centrifuge, as onboard controls. RNAseq analyses showed that microgravity inhibits cell proliferation and DNA repair, stimulates inflammatory pathways and induces ferroptosis and senescence, two pathways related to ageing. Morphological hallmarks of senescence, such as reduced nuclear size and changes in chromatin architecture, proliferation marker distribution, tubulin acetylation and lysosomal transport were identified by immunofluorescence microscopy, reinforcing the hypothesis of induction of cell senescence in microgravity during space flight. These processes could be attributed, at least in part, to the regulation of YAP1 and its downstream effectors NUPR1 and CKAP2L.
