Project description:Normal thymic T cell development is enabled by a stromal microenvironment most importantly composed of distinct epithelial cell populations in cortex and medulla. Their differentiation, growth and function require the expression of the transcription factor Foxn1. Direct targets of Foxn1 have, however, remained largely undefined. Utilizing newly created static and inducible genetic model systems, we now provide a genome wide map of Foxn1 target genes and the sequences bound by this master regulator. Foxn1 controls not only essential steps early in intrathymic lymphoid development including T cell lineage commitment but is also indispensable for later stages in T cell maturation such as the selection of CD4 and CD8 T cells. Thus, Foxn1 function critically choreographs both early and late events in thymic lympho-stromal cross-talk.

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:Cancer associated fibroblasts (CAFs), mainly responsible for the desmoplastic reaction hallmark of intrahepatic Cholangiocarcinoma (iCCA), likely take a role in tumour aggressiveness and resistance to therapy, although the molecular mechanisms involved are unknown. Aim of the study is to investigate how targeting hCAF/iCCA cross-talk with a Notch1 inhibitor namely Crenigacestat would affect cancer progressionWe used different in vitro models in 2D and we established new 3D hetero-spheroids with iCCA cells and human (h)CAFs. Results were confirmed in a xenograft model, explanted tumoral tissues underwent transcriptomic and bioinformatic analysis. hCAFs/iCCA cross-talk sustains increased migration of both KKU-M213 and KKU-M156 cells, while Crenigacestat significantly inhibits only the cross-talk stimulated migration. Hetero-spheroids grow larger than homo-spheroids,formed by only iCCA cells. Crenigacestat significantly reduced invasion and growth of hetero- but not of homo-spheroids. In xenograft models, hCAFs/KKU-M213 tumours grew significantly larger than KKU-M213 tumours, but were significantly reduced in volume by Crenigacestat treatment, which also significantly reduced the fibrotic reaction. Interpretative phenomenological analysis of the transcriptome unveiled that genes of hCAFs/KKU-M213 but not of KKU-M213 tumours increased tumour lesions, and that Crenigacestat treatment inhibited the modulated canonical pathway. Cell cycle checkpoints were the most modulated pathway. In hetero-spheroids, the number of cells increased into G2/M cell cycle phase, while Crenigacestat significantly decreased the number into G2/M phase in hetero but not in homo-spheroids. The cross-talk hCAFs/iCCA is a new target for reducing cancer progression with drugs such as Crenigacestat.

Project description:Tumors comprise a complex microenvironment of interacting malignant and stromal cell types. Much of our understanding of the tumor microenvironment comes from in vitro studies isolating the interactions between malignant cells and a single stromal cell type, often along a single pathway. To develop a deeper understanding of the interactions between cells within human lung tumors we performed RNA-seq profiling of flow-sorted malignant cells, endothelial cells, immune cells, fibroblasts, and bulk cells from freshly resected human primary non-small-cell lung tumors. We mapped the cell-specific differential expression of prognostically-associated secreted factors and cell surface genes, and computationally reconstructed cross-talk between these cell types to generate a novel resource we call the Lung Tumor Microenvironment Interactome (LTMI). Using this resource, we identified and validated a prognostically unfavourable influence of Gremlin-1 production by fibroblasts on proliferation of malignant lung adenocarcinoma cells. We also found a favorable association between infiltration of mast cells and less aggressive tumor cell behavior. These results illustrate the utility of the LTMI as a resource for generating hypotheses concerning tumor-microenvironment interactions that may have prognostic and therapeutic relevance.

Project description:Orthologous proteins often harbor numerous substitutions, but whether these differences result from neutral or adaptive processes is usually unclear. To tackle this challenge, we examined the divergent evolution of a model bacterial signaling pathway comprising the kinase PhoR and its cognate substrate PhoB. We show that the specificity-determining residues of these proteins are typically under purifying selection, but have, in α-proteobacteria, undergone a burst of diversification followed by extended stasis. By reversing mutations that accumulated in an α-proteobacterial PhoR, we demonstrate that these substitutions were adaptive, enabling PhoR to avoid cross-talk with a paralogous pathway that arose specifically in α-proteobacteria. Our findings demonstrate that duplication and the subsequent need to avoid cross-talk strongly influence signaling protein evolution. These results provide a concrete example of how system-wide insulation can be achieved post-duplication through a surprisingly limited number of mutations. Our work may help explain the apparent ease with which paralogous protein families expanded in all organisms. Two-condition experiment, mutant vs. WT in given growth media
