The Link between Osteoporosis and Frozen Shoulder: Exploring the Therapeutic Effect of TAK715 on Reversing Fibrosis and Protecting against Osteoporosis via the p38 MAPK Signaling Pathway

ABSTRACT: The global incidence of frozen shoulder (FS) and osteoporosis (OP) is high. Although FS patients may experience localized OP in the shoulder, there is still insufficient strong evidence to confirm the relationship between FS and OP. The main objective of this current research is to investigate the pathogenesis mechanism of FS and explore the connection between FS and OP.We obtained FS and OP datasets from GEO and identified crosstalk genes. We screened the p38 MAPK signaling pathway and its specific inhibitor, TAK715. We conducted flow cytometry, western blot, and PCR analyses to assess the treatment effect of TAK715 on FS synovium fibroblasts at concentrations of 1μM, 5μM, and 10μM. Additionally, we employed SD rats to validate the treatment effects of TAK715 in vivo. TAK715 was found to also intervene in the activation of osteoclasts. We successfully established a FS and OP rat model, with the FS with OP rat displaying more severe symptoms. Results demonstrated that TAK715 effectively corrected both fibrosis and osteoporosis simultaneously in vivo.The frozen shoulder with osteoporosis may exhibit more severe symptoms, and TAK715 is effective in protecting fibrosis and osteoporosis both in vitro and vivo. The therapy to correct FS and OP simultaneously by TAK715 provides novel approach in FS treatment and study.

Project description:This study was designed to identify changes in gene expression that occur when corn was grown on different landscape features. Specifically on the backslope or summit/shoulder of a hill. In rolling landscapes, plant available water varies drastically by location and soil type. Almost simultaneously, plants may be flooded out in footslope locations whereas plants in summit locations may be suffering from severe drought. The objective of this study was to determine the influence of landscape position on corn (Zea mays) productivity and gene regulation. Corn was sampled at V12 for plant growth characteristics and transcriptome analysis at summit/shoulder and lower backslope positions. Plants at the summit had 16% less leaf area and biomass compared with plants at the toeslope. Gene expression analysis using microarray chips, transcriptome analysis, and qPCR indicated that plants at the summit had 708 genes down-regulated and 399 genes up-regulated compared to control plants at the lower back slope. GSEA (Gene Set Enrichment Analysis) indicated tolerance to cold, salt, and drying were increased in summit/should plants compared to control toeslope plants. However, nutrient uptake, recovery from wounding, pest and fungal disease resistance, along with photosynthetic capacity were all down-regulated in moderate water stresses plants. These responses suggest that corn preferentially responses to water stress as the expense of its ability to respond to other stresses. Three biological replicates for the control (backslope) and six biological replicate of summit/shoulder-grown plants were collected. The resulting labeled cDNA was hybridized to the 46,000-element maize microarray chip developed by the University of Arizona using their protocol (International Microarray Workshop Handbook, 2009Gardiner et al. 2005). The hybridization scheme was a dual hybridization using a rolling circle balanced dye swap design. Thus we had three to six biological replicates for each growth condition and two technical replicates for each biological sample.
