Disturbed glycolipid metabolism activates CXCL13-CXCR5 axis in senescent TSCs to promote heterotopic ossification formation

ABSTRACT: Heterotopic ossification (HO) occurs as a common complication after injury, while its risk factor and mechanism remain unclear yet, which restricts the development of pharmacological treatment. Clinical research suggested that diabetes mellitus (DM) patients were prone to develop HO in tendon, but the solid evidence and mechanical research are still needed. Here, we combined the clinical samples and DM mice model to identify that disordered glycolipid metabolism aggravates the senescence of tendon derived stem cells (TSCs) and promotes their osteogenic differentiation. Then, combining the RNA-seq results of aging tendon, we detected the abnormally activated autocrine CXCL13-CXCR5 axis in TSCs cultured in high fat high glucose (HFHG) environment and also in aged tendon. Genetic inhibition of CXCL13 successfully alleviates the HO formation in DM mice, providing a potential therapeutical target for suppressing HO formation in DM patients after trauma or surgery.

Tenomodulin prevents trauma-induced heterotopic ossification in tendon

Project description:We have reported that loss of Tnmd leads to inferior early tendon repair characterized by fibrovascular scaring and therefore hypothesized that its lack will persistently cause deficient repair during later stages. Tnmd knockout (Tnmd-/-) and wild-type (WT) animals were subjected to complete Achilles tendon surgical transection followed by end-to-end suture. Lineage tracing revealed a reduction in tendon-lineage cells marked by ScleraxisGFP, but an increase in alpha smooth muscle actin myofibroblasts in Tnmd-/- tendon scars. At the proliferative stage, more pro-inflammatory M1 macrophages and larger collagen II cartilaginous template were detected in this group. At the remodeling stage, histological scoring revealed lower repair quality in the injured Tnmd-/- tendons, which was coupled with higher HO quantified by micro-CT. Tendon biomechanical properties were compromised in both groups upon injury, however we identified an abnormal stiffening of non-injured Tnmd-/- tendons, which possessed higher static and dynamic E-moduli. Pathologically thicker and abnormally shaped collagen fibrils were observed by TEM in Tnmd-/- tendons and this together with augmented HO resulted in diminished running capacity of Tnmd-/- mice. These novel findings demonstrate that Tnmd plays a protecting role against trauma-induced endochondral HO and can inspire the generation of novel therapeutics to accelerate repair.

PROTEIN KINASE C EPSILON COOPERATES WITH PTEN LOSS FOR PROSTATE TUMORIGENESIS THROUGH THE CXCL13-CXCR5 PATHWAY

Project description:PKCe, an oncogenic member of the PKC family, is aberrantly overexpressed in epithelial cancers. To date, little is known about functional interactions of PKCe with other genetic alterations and the effectors of this kinase that contribute to its tumorigenic and metastatic phenotype. Here we demonstrate that PKCe cooperates with the loss of the tumor suppressor Pten for the development of prostate cancer in a mouse model. Mechanistic analysis revealed that PKCe overexpression and Pten loss individually and synergically cause a remarkable up-regulation in the production of the chemokine CXCL13. Notably, targeted disruption of CXCL13 or its receptor CXCR5 in prostate cancer cells impaired their migratory and tumorigenic properties. In addition to providing evidence for an autonomous vicious cycle driven by PKCe, our studies identified a compelling rationale for targeting the CXCL13:CXCR5 axis for prostate cancer treatment.

The healing myocardium mobilizes a distinct B-cell subset through a CXCL13-CXCR5-dependent mechanism

Project description:Recent studies have revealed that B-cells can influence post-myocardial infarction (MI) inflammation and repair, but the mechanisms controlling their mobilization and in situ activity remain poorly understood. Herein, we sought to dissect the mechanisms underlying B-cell cardiotropism and assess the B-cell antigen specificity profile in an experimental model of MI. Our study reveals that B-cells that are not antigen-specifically expanded readily infiltrate the infarcted myocardium via the CXCL13-CXCR5 axis. The restricted distribution of CXCR5 among hB cells could offer a suitable opportunity to selectively target this leukocyte subset therapeutically while minimally interfering with other local or systemic immunological processes.

Wisp inhibits chondrogenic differentiation in heterotopic ossification

Project description:Heterotopic ossification (HO) is the formation of extra-skeletal bone in muscle and soft tissues. Better characterization of the signaling pathways predisposing to HO is critical to identifying therapies directed against this common and potentially debilitating condition. WISP-1 (WNT1-inducible-signaling pathway protein 1) is a CCN family member and is expressed in skeletal cells during bone development or repair. Here, we sought to comprehensively explore the significance of WISP-1 across mouse and human HO. Among CCN family members, local Wisp1 expression was most highly upregulated within experimental trauma-associated HO by RNA sequencing, and increased Wisp1 corresponded to gene markers of osteochondral differentiation. WISP1 immunolocalization demonstrated conserved expression in osteochondral cells across mouse and human HO, including an FOP-like model, post-traumatic model, and human examples of non-genetic HO. Transgenic Wisp1 global knockout demonstrated an increase in cartilage and bone in a trauma-induced HO model. Microarray and in vitro culture of Wisp1 null cells suggested that WISP1 functions as a negative regulator of chondrogenic differentiation, and that Wisp1 deletion results in unrestrained endochondral HO formation. siRNA mediated WISP1 knockdown in human progenitor cells confirmed this finding. Overall, these findings suggest that endogenous WISP1 has pathophysiologic relevance in trauma-induced HO and functions as a negative regulator of ectopic chondrogenesis.

Esrrb plays an important role in maintaining self-renewal of trophoblast stem cells (TSCs) and reprogramming somatic cells to induced TSCs [ChIP-Seq]

Project description:Trophoblast stem cells (TSCs) are derived from the trophoectoderm of a blastocyst and can maintain self-renewal in vitro. Meanwhile, essential insights into the molecular mechanisms controlling placental developmental could be gained by using TSCs that can differentiate into the various placental trophoblast cell types in vitro. Esrrb is a transcription factor with pivotal roles in maintaining TSCs’ self-renewal, but the exact transcriptional networks that Esrrb involved in TSCs are largely unknown. In the present study, we elucidated the function of Esrrb during TSC self-renewal and differentiation. We demonstrate that precise levels of Essrb are critical for TSCs stemness maintenance and normal trophoblast differentiation, as Esrrb depletion results in down-regulation of the key TSC-specific transcription factors, consequently causing TSCs differentiation and forced expression of Esrrb can partially block TSCs differentiation in the absence of FGF4. This function of Esrrb is exerted by directly binding and activating a core set of TSC-specific target genes including Cdx2, Eomes, Sox2, Fgfr4 and BMP4. Furthermore, we investigate the role of Esrrb in reprogramming of mouse embryonic fibroblasts (MEFs) to induced TSCs (iTSCs). We show that Esrrb can facilitate the conversion of iTSCs from MEFs. Moreover, Esrrb can substitute for Eomes during this conversion process. Our findings provide a better understanding of the molecular mechanism of Esrrb in maintaining TSCs self-renewal and iTSCs reprogramming.

Role of the CXCL13/CXCR5 Axis in Autoimmune Diseases.

Project description:CXCL13 is a B-cell chemokine produced mainly by mesenchymal lymphoid tissue organizer cells, follicular dendritic cells, and human T follicular helper cells. By binding to its receptor, CXCR5, CXCL13 plays an important role in lymphoid neogenesis, lymphoid organization, and immune responses. Recent studies have found that CXCL13 and its receptor CXCR5 are implicated in the pathogenesis of several autoimmune diseases, such as rheumatoid arthritis, multiple sclerosis, systemic lupus erythematosus, primary Sjögren's syndrome, myasthenia gravis, and inflammatory bowel disease. In this review, we discuss the biological features of CXCL13 and CXCR5 and the recent findings on the pathogenic roles of the CXCL13/CXCR5 axis in autoimmune diseases. Furthermore, we discuss the potential role of CXCL13 as a disease biomarker and therapeutic target in autoimmune diseases.
