PIP-seq identifies novel heterogeneous lung innate lymphocyte population activation after combustion product exposure

Project description:Innate lymphoid cells (ILCs) are a heterogeneous population that play diverse roles in airway inflammation after exposure to allergens and infections. However, how ILCs respond after exposure to environmental toxins is not well understood. Here we show a novel method for studying the heterogeneity of rare lung ILC populations by magnetic enrichment for lung ILCs followed by particle-templated instant partition sequencing (PIP-seq). Using this method, we were able to identify novel group 1 and group 2 ILC subsets that exist after exposure to both fungal allergen and burn pit-related constituents (BPC) that include dioxin, aromatic hydrocarbon, and particulate matter. Toxin exposure in combination with fungal allergen induced activation of specific ILC1/NK and ILC2 populations as well as promoted neutrophilic lung inflammation. Oxidative stress pathways and downregulation of specific ribosomal protein genes (Rpl41 and Rps19) implicated in anti-inflammatory responses were present after BPC exposure. Increased IFNγ expression and other pro-neutrophilic mediator transcripts were increased in BPC-stimulated lung innate lymphoid cells. Further, the addition of BPC induced Hspa8 (encodes HSC70) and aryl hydrocarbon transcription factor activity across multiple lung ILC subsets. Overall, using an airway disease model that develops after occupational and environmental exposures, we demonstrate an effective method to better understand heterogenous ILC subset activation.

Compound PIP-RBPJ-1 treated human neural stem cells

Project description:The study of the compond PIP-RBPJ-1‘ function on neural stem cell. Synthetic DNA-binding inhibitors capable of gaining precise control over neurogenesis factors could obviate the current clinical barriers associated with small molecule use in regenerative medicine. Here, we show the design and bio-efficacy of a synthetic ligand PIP-RBPJ-1 to cause promoter-specific suppression of neurogenesis-associated HES1, and its downstream genes. Furthermore, PIP-RBPJ-1 alone could alter the neural system-associated notch signaling factors and remarkably induce neurogenesis with an efficiency that is comparable to a conventional approach. Here is one day treatment of the PIP-RBPJ-1 on neural stem cells.

A functional and regulatory network associated with PIP expression in human breast cancer

Project description:Background The PIP (prolactin-inducible protein) gene has been shown to be expressed in breast cancers, with contradictory results concerning its implication. As both the physiological role and the molecular pathways in which PIP is involved are poorly understood, we conducted a combined gene expression profiling and network analysis studies on selected breast cancer cell lines presenting distinct PIP expression levels and hormonal receptor status, to explore the functional and regulatory network of PIP co-modulated genes. Results Microarray analysis allowed identification of genes co-modulated with PIP independently of modulations resulting from hormonal treatment or cell line heterogeneity. Relevant clusters of genes that can discriminate between [PIP+] and [PIP-] cells were identified. Functional and regulatory network analyses based on knowledge database revealed a master network of PIP co-modulated genes, including many interconnecting oncogenes and tumor suppressor genes, half of which were detected as differentially expressed through high-precision measurements. The networks identified appear associated with an inhibition of proliferation coupled with an increase of apoptosis and an enhancement of cell adhesion in breast cancer cell lines. Finally, the STAT5 motif was identified in promoters of an important part of genes belonging to the PIP networks. Conclusion Our global exploratory approach was found to be an effective strategy to identify the biological pathways modulated along with the PIP expression, thus supporting good prognostic value of disease-free survival time in breast cancer based on previous reports focusing on PIP’s favorable signature. Moreover, our data allowed us to provide the first insight in its regulatory subnetwork in which STAT5 appears as a potential key regulator.

Repeated exposure and switching study of cigarette smoke and next generation tobacco product using 3D human bronchial epithelial cells

Project description:Next generation product such as heat-not-burn type product and e-cigarette emit lower yields of chemical constituents than cigarette because combustion of tobacco leaves is not associated with their vapor generation. Therefore it is expected that the usage of these product bring beneficial impact on public health. However, risk-reduced potential as well as risk concerns in long-term use of these products has not yet been fully understood. In this study, we intended to estimate the risk reduced potential of our proprietary novel tobacco vapor product (NTV) by repeated exposure of in vitro 3D bronchial epithelial cells to NTV vapor in comparison with repeated exposure to cigarette smoke. In addition, to reflect the realistic situation of smokers, exposure switching from cigarette smoke to NTV vapor and cigarette smoke exposure cessation were conducted.
