Project description:Cancer-associated fibroblasts (CAFs) in the tumor microenvironment are involved in the progression of esophageal squamous cell carcinoma (ESCC). We generated CAF-like cells by direct co-culture of human bone marrow-derived mesenchymal stem cells (MSCs), one of the origins of CAFs, with ESCC cell lines and found that periostin is highly expressed in CAF-like cells. Periostin activated Akt and Erk signaling pathways in ESCC cells, enhancing survival and migration via integrin β4, one of the receptors for periostin. Periostin also enhanced migration of MSCs and macrophages and caused macrophages to acquire tumor-associated macrophage (TAM)-like properties. High periostin expression in cancer stroma was associated with several clinicopathological factors and expressions of CAF markers and numbers of infiltrating TAMs. Moreover, ESCC patients with high periostin expression exhibited significantly poor postoperative outcomes. Thus, periostin secreted from CAFs enhanced the migration of ESCC cells, MSCs, and macrophages and contributed to developing the tumor microenvironment. These results indicate that periostin may be a novel therapeutic target for ESCC.

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:Basal-like breast cancer (BLBC) cells share phenotypic similarities with cancer stem cells (CSCs) but the underlying molecular basis for this connection remains elusive. We hypothesized that BLBC cells are able to establish a niche permissive to the maintenance of CSCs and found that tumor cell-derived periostin (POSTN), a component of the extracellular matrix, as well as a corresponding cognate receptor, integrin αvβ3, are highly expressed in a subset of BLBC cell lines as well as in cancer stem cell-enriched populations. Furthermore, we demonstrated that an intact periostin-integrin β3 signaling axis is required for the maintenance of breast CSCs. POSTN activates the ERK signaling pathway and regulates NF-κB-mediated transcription of key cytokines, namely IL6 and IL8, which in turn mediate downstream activation of STAT3. In summary, these findings suggest that BLBC cells have an innate ability to establish a microenvironmental niche supportive of CSCs.

Project description:Human squamous cell cancers are the most common epithelially derived malignancies. One example is esophageal squamous cell carcinoma (ESCC), which is associated with a high mortality rate that is related to a propensity for invasion and metastasis. We report that periostin, a highly expressed cell adhesion molecule, is a key component of a novel tumor invasive signature obtained from an organotypic culture model of engineered ESCC. This tumor invasive signature classifies with human ESCC microarrays, underscoring its utility in human cancer. Genetic modulation of periostin promotes tumor cell migration and invasion as revealed in gain of and loss of function experiments. Inhibition of EGFR signaling and restoration of wild-type p53 function were each found to attenuate periostin, suggesting interdependence of two common genetic alterations with periostin function. Our studies reveal periostin as an important mediator of ESCC tumor invasion and they indicate that organotypic (3D) culture can offer an important tool to discover novel biologic effectors in cancer. Invading and non-invading genetically engineered human esophageal cells with hTERT and EGFR overexpression and p53 mutations were grown in organotypic culture. These invading and non-invading cells were excised using laser-capture microdissection. RNA was isolated and amplified for Affymetrix U133 microarrays. Subsequent microarray analysis & comparison with 2 independent cohorts of primary ESCC tumors revealed upregulation of periostin as gene with highest upregulation found in novel tumor invasive signature in esophageal cancer.

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.
