Project description:In order to define the underlying mechanism of fluoride resistance in mammals and provide a theoretical basis for fluorosis treatment, high-throughput sequencing was applied to map the genetic changes of fluoride-resistant mouse osteoblasts. Fluoride-tolerant MC3T3-E1 cells were developed by gradient fluoride exposure. The differentially expressed genes of fluorine-resistant MC3T3-E1 cells were identified by high-throughput sequencing. High-throughput RNA sequencing identified 2702 differentially expressed genes (DEGs) showed more than 2-fold difference in 30ppm FR MC3T3-E1 cells, of which 17 DEGs were associated with ferroptosis.

Project description:Tissue response following implantation determines the success of the healing process. This response is not only dependent on the chemical properties of the implant surface but also by the surface topography or its roughness. Although in vitro and in vivo studies show improved results with rough- and fluoride-modified implants, the mechanisms behind these findings are still unknown. Here, we have used a two step procedure to identify novel genes related to the early cell response of primary human osteoblasts to roughness and fluoride-modified titanium implants. 217 genes were identified by microarray analysis as response genes to roughness and 198 genes as response genes to fluoride. 11 of these identified genes have been related to bone and mineralization and were further investigated by real-time RT-PCR. After one day of culture, TLR3, ANKH, DCN, OC and RUNX2 were classified as responsive genes to roughness; DLX2 and TUFT1 as responsive genes to fluoride treatment. COLL-I, PTHLH, HES1, FST, ENPP1 and THRA as responsive genes to both, roughness and fluoride treatment. In conclusion, our strategy was useful for identifying novel genes that might be involved in the early response of osteoblasts to roughness and fluoride treatment of titanium implants.

In conclusion, our strategy was useful for identifying novel genes that might be involved in the early response of osteoblasts to roughness and fluoride treatment of titanium implants. Human osteoblasts were cultured for 24 hours on titanium disks modified either with polished surfaces (P), grit-blasted surfaces (GB), or grit-blasted High Fluor treated surfaces (GB-HF). After 24 hours of culture RNA was isolated. 3 arrays were hybridized, one with the isolated RNA from cells cultured on titanium polished surfaces (P), one with the isolated RNA from cells cultured on titanium grit-blasted surfaces (GB) and one with the isolated RNA from cells cultured on titanium grit-blasted HF treated surfaces (GB-HF).

Project description:Though fluoride is considered an essential trace element, chronic exposure to fluoride is known to cause toxic effects. Chronic exposure of high concentration of fluoride may leads to fluorosis. To understand the molecular mechanism of fluoride induced toxicity gene expression profiling was performed on osteosarcoma cells (HOS). Cells were exposed to sub-lethal concentration of fluoride (8 ppm) for 30 days. Our result demonstrates that fluoride alters multiple biological pathways including bone development, osteoblast differentiation and apoptotic pathways.

Project description:Although an appropriate range of fluoride is thought to be safe and effective, excessive fluoride intake results in toxic effects in either hard tissues of teeth and skeleton or soft tissues of kidney, lung and brain. It is also well known that fluoride at a millimolar range elicits the complex cellular responses such as enzyme activity, signal transduction and apoptosis in many kinds of cells. However, its toxic effects are still unclear. In this study, to identify genes involved in cell death induced by sodium fluoride (NaF) in rat oral epithelial ROE2 cells, global-scale gene expression analysis was carried out using a GeneChip® system.

Project description:To investigate the molecular mechanism of F toxicity on glial cells we have performed a large transcriptomic and proteomic analysis over to two relevant fluoride doses. U87 glial-like cells were exposed to 0,095µg/mL and 0.22µg/ml for 10 days to mimic a chronic exposure to fluoride. A total of 62 genes and 209 genes were modulated after exposure to 0.095 and 0.22µg/ml respectively. The number of proteins modulates were 20 and 10 respectively. Gene Ontology annotation revealed changes on cellular metabolism and cell death regulation pathways such as MAPK and ERK1/ERK2. Proteomics analysis have confirmed changes on energy metabolism and revealed changes on cytoskeleton components.

HOS cells grown in MEM were treated with fluoride and total RNA was isolated from cells after 30 days exposure. Three replicates per group were used for the experiment.
