Project description:Chondrocyte transcriptome of periostin knockout and wild-type mice showed that 4 genes (Tm4sf1, Evx2, Sscaml1, and GDf10) are statistically significant with FDR <= 0.05. 1247 genes have unadjusted p-values less than 0.05, but only 12 of those have log 2 fold-changes >= |2|. The GO biological process results do show statistically significant up-regulation of cell adhesion, cell signaling, angiogenesis, and differentiation in the KO samples.

Project description:Periostin participates in different processes involved in connective tissue homeostasis. It is also involved in repairment of damaged tissues. We used the osteoblast murine cell line MC3T3-E1 cell line to show how overexpresion of periostin is able to increase their adhesion properties while diminishing their migration capacity. By differential gene expression we evaluated putative targets involved in those cellular properties.

Project description:Idiopathic pulmonary fibrosis (IPF) is a devastating disease characterized as progressive and irreversible fibrosis in the interstitium of lung tissues. There is still an unmet need to develop a novel therapeutic drug for IPF. We have previously demonstrated that periostin, a matricellular protein, plays an important role in the pathogenesis of pulmonary fibrosis. However, the underlying mechanism of how periostin causes pulmonary fibrosis remains unclear. In this study, we sought to see whether the cross-talk between transforming growth factor-b (TGF-b), a central mediator in the pathogenesis of pulmonary fibrosis, and periostin in lung fibroblasts leads to generation of pulmonary fibrosis and whether taking advantage of the cross-talk between TGF-b and periostin, inhibitors for integrin aVb3, a periostin receptor, can block pulmonary fibrosis in the model mice. We found that there exists a cross-talk between TGF-b and periostin signals via aVb3/b5 converging into Smad3. This cross-talk is important for expression of several downstream molecules of TGF-b including serpin family E member 1, CCN family member 2/connective tissue growth factor, insulin-like growth factor binding protein-3, and IL-11, all of which have been already shown to be important for pulmonary fibrosis. We, moreover, found several potent integrin inhibitors to block the cross-talking with TGF-b signals and CP4715, one of the compounds, improved bleomycin-induced pulmonary fibrosis in mice. These results suggest that the cross-talk between TGF-b and periostin can be targeted for pulmonary fibrosis and that CP4715 can be a potential therapeutic agent to block the cross-talk between TGF-b and periostin.

Project description:Periostin, a matricellular protein, has been reported to be important in supporting tumor cell dissemination. However, the molecular mechanisms underlying periostin function within the tumor microenvironment are poorly understood. In this study, we observe that loss of periostin decreases esophageal squamous cell carcinoma (ESCC) tumor growth in vivo and demonstrate that periostin cooperates with a conformational missense p53 mutation to enhance invasion. Pathway analyses reveal that invasive esophageal cells expressing periostin and p53R175H mutation display activation of signal transducer and activator of transcription 1 (STAT1) target genes, suggesting that the induction of STAT1 and STAT1-related genes could foster a permissive microenvironment that facilitates invasion of esophageal epithelial cells into the extracellular matrix (ECM). Genetic knockdown of STAT1 in transformed esophageal epithelial cells underscores the importance of STAT1 in promoting invasion and potentiate tumor resistance to genotoxic stress. Furthermore, we find that STAT1 is activated in ESCC xenograft tumors but this activation is attenuated with inducible knockdown of periostin in ESCC tumors. Overall, these results highlight the molecular mechanisms supporting the capacity of periostin in mediating tumor invasion during ESCC development.

Project description:Cancer cell dissemination to sentinel lymph nodes associates with poor patient outcomes, particularly in breast cancer. The process by which cancer cells egress from the primary tumor upon interfacing with the lymphatic vasculature is complex and driven by dynamic interactions between cancer cells and stromal cells, including cancer associated fibroblasts (CAFs). The matricellular protein periostin can distinguish CAF subtypes in breast cancer and is associated with increased desmoplasia and disease recurrence in patients. However, since periostin is secreted, periostin-expressing CAFs are difficult to characterize in situ, limiting our understanding of their specific contribution to cancer progression. Here, we used in vivo genetic labeling and ablation to lineage trace periostin+ cells and characterize their functions during tumor growth and metastasis. Periostin-expressing CAFs were spatially found at periductal and perivascular margins, were enriched at lymphatic vessel peripheries, and were differentially activated by highly-metastatic cancer cells versus poorly-metastatic counterparts. Surprisingly, genetically depleting periostin+ CAFs slightly accelerated primary tumor growth but impaired intratumoral collagen organization and inhibited lymphatic, but not lung, metastases. Periostin ablation in CAFs impaired their ability to deposit aligned collagen matrices and inhibited cancer cell invasion through collagen and across lymphatic endothelial cell monolayers. Thus, highly-metastatic cancer cells mobilize periostin-expressing CAFs in the primary tumor site that promote collagen remodeling and collective cell invasion within lymphatic vessels and ultimately to sentinel lymph nodes.

Project description:Idiopathic pulmonary fibrosis (IPF) is a devastating disease with only three to five years of the median survival. Fibroblast proliferation is a hallmark of IPF as well as secretion of extracellular matrix proteins from fibroblasts. However, it is still uncertain how IPF fibroblasts acquire the ability to progressively proliferate. Periostin is a matricellular protein that is highly expressed in the lung tissues of IPF patients and plays a critical role in the pathogenesis of pulmonary fibrosis. However, it remains undetermined whether periostin affects proliferation of lung fibroblasts. In this study, we first comprehensively tried to identify periostin-dependently expressed genes in lung fibroblasts finding that many cell-cycle–related genes are involved in the gene profile. We confirmed that periostin silencing downregulates expression of several cell-cycle–related molecules including the cyclin family, the CDK family, the E2F family, and the transcriptional factors such as B-MYB and FOXM1 in lung fibroblasts. Accordingly, periostin silencing slowed proliferation of lung fibroblasts and affects the distribution of cell cycle particularly at the G1/S checkpoint and drives the cells into G1 arrest. Lung fibroblasts derived from IPF patients also required periostin for maximum proliferation. Moreover, CP4715, a potent inhibitor against integrin V3, a periostin receptor, downregulated proliferation along with expression of cell-cycle–related genes in IPF lung fibroblasts as well as normal lung fibroblasts. These results demonstrate that periostin plays a critical role in proliferation of lung fibroblasts and provide us a beneficial basis to apply the inhibitors against the periostin/integrin V3 interaction to IPF patients.

Project description:To explore the effects of periostin on tumor-associated macrophagess, we first sorted CD14+ monocytes from peripheral blood mononuclear cells of healthy donors using magnetic-activated cell sorting and then induced their differentiation into macrophages by culture with M-CSF for 5 days. In the absence of IL-4 stimulation, these macrophages expressed CD163 and Arg1 (a marker of M2 macrophage activation) but not CD206, suggesting that they were similar to macrophages in the early stage of mycosis fungoides (low frequency of CD206+ cells and low IL-4 expression). We then stimulated these macrophages with or without 100 ng/ml of periostin for 6 hours and examined gene expression using a cDNA microarray. Periostin stimulated gene expression on monocyte-derived macrophages was measured at 6 hours after exposure to doses of 100 ng/ml periostin.
