Project description:Interleukin (IL)-11 belongs to a member of the IL-6 family of cytokines and is involved in a variety of cellular responses. However, the origin and functions of IL-11-producing (IL-11+) cells are not fully understood. To characterize IL-11+ cells in vivo, we generated Il11 reporter mice. IL-11+ cells rapidly appeared in the colon of mice after dextran sulfate sodium treatment. IL-11+ cells expressed fibroblast markers and genes associated with cell proliferation and tissue repair. IL-11+ cells also appeared in the colon of three murine tumor models and human colorectal cancers. Deletion of Il11ra1 or Il11 attenuated the development of colitis-associated colorectal cancers in mice. IL-11 induced STAT3 phosphorylation in colonic fibroblasts, and injection of IL-11 receptor agonist upregulated many genes that were enriched in IL-11+ cells. Together, tumor cells induced IL-11+ fibroblasts, and a feed-forward loop between IL-11 and IL-11+ fibroblasts might constitute a niche for promoting tumor development.

Project description:Interleukin (IL)-11 is a member of the IL-6 family of cytokines and involved in multiple cellular responses, including tumor development. However, the origin and functions of IL-11-producing (IL-11+) cells are not fully understood. To characterize IL-11+ cells in vivo, we generated Il11 reporter mice. IL-11+ cells appeared in the colon of murine tumor and acute colitis models. Il11ra1 or Il11 deletion attenuated the development of colitis-associated colorectal cancer. IL-11+ cells expressed fibroblast markers, and genes associated with cell proliferation and tissue repair. IL-11 induced the activation of colonic fibroblasts and epithelial cells through phosphorylation of STAT3. Human cancer database analysis revealed that a set of genes enriched in IL-11+ fibroblasts was elevated in human colorectal cancer, and correlated with reduced recurrence-free survival. Together, IL-11+ fibroblasts activate both tumor cells and fibroblasts via secretion of IL-11, thereby constituting a feed forward loop between tumor cells and fibroblasts in the tumor microenvironment.

Project description:In adult mammals, tissue damage after myocardial infarction induces myofibroblast differentiation and the formation of a permanent, functionally inert scar. However, the molecular mechanisms that govern myofibroblast differentiation and scarring remain poorly understood. Some vertebrates like zebrafish display a remarkable regenerative potential with only limited and transient fibrosis after tissue damage, including in the heart. Here, employing comparative expression profiling coupled with loss-of-function approaches, we identified the canonical Interleukin-11/Stat3 signaling axis as a core component of regeneration in zebrafish. Notably, animals with loss of Interleukin-11 receptor (Il11ra) function reach adulthood without overt developmental defects, but exhibit strongly impaired cardiac regeneration with increased myofibroblast differentiation and the formation of a permanent collagenous scar, similar to what is observed in adult mammals. Using zebrafish fate-mapping approaches, reporter lines and human primary cell culture methods, we provide evidence that Interleukin-11 signaling limits endothelial-to-myofibroblast transdifferentiation and maintains a pro-regenerative niche to promote cardiac regeneration. Altogether, our data reveal a vital role for endothelial Interleukin-11/Stat3 signaling in containing injury-induced cardiac fibrosis.

Project description:Homeostasis of self-renewing small intestinal crypts results from neutral competition between Lgr5 stem cells, small cycling cells located at crypt bottoms1, 2. Lgr5 stem cells are interspersed between terminally differentiated Paneth cells, that are known to produce bactericidal products such as lysozyme and cryptdins/defensins3. Single Lgr5-expressing stem cells can be cultured to form long-lived, self-organizing crypt-villus organoids in the absence of non-epithelial niche cells4. Here, we note a close physical association of Lgr5 stem cells with Paneth cells in vivo and in vitro. CD24+ Paneth cells express EGF, TGF?, Wnt3 and the Notch-ligand Dll4, all essential signals for stem cell maintenance in culture. Co-culturing of sorted stem cells with Paneth cells dramatically improves organoid formation. This Paneth cell requirement can be substituted by a pulse of exogenous Wnt. Genetic removal of Paneth cells in vivo results in the concomitant loss of Lgr5 stem cells. In colon crypts, CD24+ cells residing between Lgr5 stem cells may represent the Paneth cell equivalents. We conclude that Lgr5 stem cells compete for essential niche signals provided by a specialized daughter cell, the Paneth cell. We used intestinal cell fractions from Lgr5-EGFP-ires-CreERT2 mice, expressing GFP under the control of the Lgr5 promoter. RNA was isolated from two FACS sorted cell populations: stem cells were sorted based on high level of GFP expression (GFPhi) and Paneth cells were sorted based on high level of CD24 expression (CD24hi) and high side-scatter (SSChi). Differentially labelled cRNA from GFPhi and CD24hi/SSChi cells from two different sorts (each combining ten individual mice) were hybridized on 4X44K Agilent Whole Mouse Genome dual colour Microarrays (G4122F) in two dye swap experiments, resulting in four individual arrays.

Project description:Our results introduce interleukin (IL)-11 as a new cytokine that may play a role in the development of the autoimmune response in patients with relapsing remitting multiple sclerosis (RR MS). IL-11 was found to be the highest up-regulated cytokine in the serum and cerebrospinal fluid (CSF) from patients with clinically isolated syndrome (CIS) suggestive of MS. It was also increased in the serum and CSF of patients with clinically definitive RRMS and during the clinical relapses of the disease. CD4+ cells represent a predominant cell source of IL-11 in the peripheral circulation, and the percentage of IL-11+CD4+ cells is significantly increased in CIS patients in comparison to healthy controls (HCs). Furthermore, we have identified IL-11 as a new Th17-promoting cytokine. IL-11 induces a differentiation of naïve CD4+ T cells into Th17 cells, as well as Th17 memory cell expansion, characterized by secretion of IL-17A, IL-17F, IL-21 and IL-22. Since the Th17 cytokines IL-17F, IL-21 and TNF- induced differentiation of naïve cells in the IL-11-secreting CD4+ cells, we propose that cross-talk between IL-11+CD4+ and Th17-cells may play a role in the initiation and propagation of the autoimmune response in RRMS. PBMCs were separated from 15 CIS patients and 7 HCs, and the total RNA was extracted and used for gene array hybridization as described previously. To detect differential gene expression profiles between the CIS patients and HCs, a two class paired test of significance analysis was used.

Project description:Recent studies have implicated genes that control actin cytoskeleton dynamics as important regulators in cellular invasion, a critical step in metastasis. Many of their downstream pathways still remain to be discovered. MicroRNAs have emerged as important epigenetics regulators of important cellular processes and aid in the identification of pathways involved in breast cancer progression and metastasis. In this study, we characterized the miR-206 downstream pathway specifically its direct target, Twinfilin (TWF1), a g-actin regulator and their downstream target, interleukin-11 (IL-11). We determined that miR-206 and TWF1 regulate IL-11 expression through the mycocardian-related transcription factor (MRTF-A or MKL1) and serum response factor (SRF) complex. Identification of this novel pathway that regulates breast cancer invasion will aid in the understanding of metastasis and development of new treatment strategies.
