Identification of early response genes to low-intensity pulsed ultrasound in bone marrow stromal cells

Project description:Low-intensity pulsed ultrasound (LIPUS) has been applied as a therapeutic adjunct to promote fracture healing. However, the detailed molecular mechanisms by which LIPUS promotes bone fracture healing have not yet been fully elucidated. In the present study, the early response genes elicited by low-intensity pulsed ultrasound (LIPUS) in bone marrow stromal cells (BMSCs) were investigated using GeneChip® oligonucleotide microarrays.

Gene expression in response to low-intensity pulsed ultrasound treatment of bone marrow cells under osteogenic conditions in vitro

Project description:We performed a comprehensive analysis of gene expression changes following low-intensity pulsed ultrasound (LIPUS) treatment of cultured bone marrow cells under bone formation conditions, using cDNA microarray analysis Bone marrow cells were obtained from the femora of rats and were suspended in an osteogenic medium to make a cell culture. After cultures were established, test cultures were exposed to LIPUS via the base of the cell culture plates for 15 min/day on days 3–9 (LIPUS group). Control cultures (without LIPUS exposure) were otherwise treated identically to the LIPUS group. On day 10, total RNA was extracted from both sets of cultures and hybridized to microarray slides, the data sets were analysed. Markers for differentiated osteoblasts and osteocytes, as well as collagen-related genes, cell adhesion factors were up-regulated in LIPUS group on day 10. Gene expression in response to LIPUS treatment of bone marrow cells were measured on day 10 after cultures were established. Experiments were performed at each conditions (LIPUS or Control).

Osteocytes as main responders to Low Intensity Pulsed Ultrasound for the treatment of fracture healing

Project description:Skeletal tissue is known to respond to mechanical stress. Ultrasound stimulation is one of mechanical stress and low intensity pulsed ultrasound (LIPUS) devices have been clinically utilized to promote the fracture healing. However, it is still not clear which skeletal cells, especially osteocytes or osteoblasts, mainly respond to LIPUS stimulation and how they contribute to fracture healing. To examine that, we utilized medaka known to have bones without embedded osteocytes and zebrafish known to have bones with embedded osteocytes as an in vivo model. Interestingly, fracture healing was accelerated by ultrasound stimulation in zebrafish but not in medaka. To examine the molecular events induced by LIPUS stimulation in osteocyte, we performed RNA-sequencing with the murine long bone osteocyte Y4 (MLO-Y4) cell line exposed to LIPUS. 179 genes reacted to LIPUS stimulation and functional cluster analysis defined that several molecular signatures related in immunity, secretion and transcription. Especially, most of isolated transcription related genes were modulated by LIPUS also in vivo experiments using zebrafish. Target genes analysis showed that inflammatory response and bone formation in fracture healing could be transcriptionally regulated in osteocytes by LIPUS stimulation. Among these transcription genes, early growth response (Egr) 1,2, JunB, Forkhead box Q1 (FoxQ1) and nuclear factor of activated T cells (NFAT) c1 were not altered by LIPUS in medaka unlike zebrafish suggesting that these genes would be key transcriptional regulator of LIPUS-dependent fracture healing through osteocytes. In this study, we revealed bone-equipped osteocytes is necessary for LIPUS-induced promotion of fracture healing through the transcriptional control of target genes presumably to activate neighboring cells involved in fracture healing event.

Effects of low-intensity pulsed ultrasound on the microorganisms of expressed prostatic secretion in patients with IIIB prostatitis.

Project description:To detect and analyze the changes of microorganisms in expressed prostatic secretion (EPS) of patients with IIIB prostatitis before and after low-intensity pulsed ultrasound (LIPUS) treatment, and to explore the mechanism of LIPUS in the treatment of chronic prostatitis (CP). 25 patients (study power was estimated using a Dirichlet-multinomial approach and reached 96.5% at α = 0.05 using a sample size of 25) with IIIB prostatitis who were effective in LIPUS treatment were divided into two groups before and after LIPUS treatment. High throughput second-generation sequencing technique was used to detect and analyze the relative abundance of bacterial 16 s ribosomal variable regions in EPS before and after treatment. The data were analyzed by bioinformatics software and database, and differences with P < 0.05 were considered statistically significant. Beta diversity analysis showed that there was a significant difference between groups (P = 0.046). LEfSe detected four kinds of characteristic microorganisms in the EPS of patients with IIIB prostatitis before and after LIPUS treatment. After multiple comparisons among groups by DESeq2 method, six different microorganisms were found. LIPUS may improve patients' clinical symptoms by changing the flora structure of EPS, stabilizing and affecting resident bacteria or opportunistic pathogens.

Anti-inflammatory role of low intensity pulsed ultrasound in inhibiting LPS-induced M1 polarization of RAW264.7 via Wnt2b/AXIN/β-catenin

Project description:Low-intensity pulsed ultrasound (LIPUS) is a special type of low intensity ultrasound. In periodontal disease, LIPUS was applied as an adjuvant and non-invasive therapeutic treatment. While, the specific mechanism of LIPUS in the treatment of periodontal disease is not quite clear.RAW264.7 cells were induced to M1/M2 macrophage-like polarization by LPS/IL4. LIPUS was performed to stimulate RAW264.7 cells at an intensity of 45 mW/cm2, 25 min, interval 24 h, twice. The polyA mRNA sequencing of LPS induced RAW264.7 cells, LPS induced and LIPUS treated RAW264.7 cells were conducted.Our results suggested that LIPUS played an anti-inflammatory role by inhibiting LPS-induced M1 polarization of RAW264.7 cells in an Wnt2b/AXIN/β-catenin dependent way. LIPUS may inhibit inflammation in periodontal diseases by regulating macrophage differentiation, so as to play a therapeutic role in periodontal diseases.
