The Synthetic Coolant (WS-23) in Disposable Electronic Cigarettes Impairs Cytoskeletal Function in EpiAirwayTM Tissues Exposed at the Air Liquid Interface

ABSTRACT: WS-23 is a synthetic coolant added to disposable 4th generation electronic cigarettes at high doses (up to 40 mg/mL). Here, we show the effects of pure WS-23 on the human bronchial epithelium treated at the air-liquid-interface in a cloud chamber exposure system. Both IPA and DAVID analysis show of the affects of WS-23 are related to impairment of actin cytoskeleton signaling, cell adhesion, cell spreading, and cell movement. Follow up assays on bronchial epithetlial cell line BEAS-2B further support the impairment of actin cytoskeleton signaling and actin depolymerization, as well as inhibition of cell movement, spreading, and gap closure. These results suggest that at the concentrations of WS-23 found in popular disposable electronic cigarettes, there is likely to be an adverse effect on actin cytoskeleton signaling in bronchial epithelial cells of users.

Expression profiling of NM1 KO and WT mice

Project description:Plasma membrane tension is an important feature that determines the cell shape and influences processes such as cell motility, spreading, endocytosis and exocytosis. Unconventional class 1 myosins are potent regulators of plasma membrane tension because they physically link the plasma membrane with the adjacent cytoskeleton. We identified nuclear myosin 1 (NM1) - a putative nuclear isoform of myosin 1c (Myo1c) - as a new player in the field. Although having specific nuclear function, we show that NM1 localizes preferentially to the plasma membrane. Deletion of NM1 causes more than 50% increase in the elasticity of the plasma membrane around the actin cytoskeleton as measured by atomic force microscopy. This higher elasticity of NM1 knock-out cells leads to 25% higher resistance to short-term hypotonic environment and rapid cell swelling. In contrary, overexpression of NM1 in WT cells leads to additional 30% reduction of their survival. We have brought evidence that NM1 has a direct functional role in the cytoplasm as a dynamic linker between the cell membrane and the underlying cytoskeleton, regulating the degree of effective plasma membrane tension. We used tissues from NM1 WT and KO mice with highest expression of NM1, lungs and heart (3 replicates each) and skin fibroblast derived from each mice (2 replicates each)

RSV-induced Cytoskeletal Inflammation

Project description:We studied RSV infection in an appropriate in vitro model of respiratory epithelium, a pseudostratified and fully differentiated mucociliary epithelium of normal human bronchial epithelial (NHBE) cells. RSV infection increased actin cytoskeleton without compromising adherent-, tight-, and tricellular-junctions as well as ciliary functions and epithelial tissue barrier integrity. This increased cytoskeleton depends on actin polymerization and the induction of proinflammatory cytokines and chemokines. Thus, we observed a novel signature “increased cytoskeleton” termed “cytoskeletal inflammation” in RSV-infected respiratory epithelium that presumably lacks classical antigen presenting cells, such as resident dendritic cells and macrophages. Our results suggest that RSV-induced cytoskeletal inflammation is a noncanonical earliest host response to the pathogen and contributes to airway inflammation.

TFAM loss induces nuclear actin assembly upon mDia2 malonylation to promote liver cancer metastasis

Project description:The mechanisms underlying cancer metastasis remain poorly understood. Here, we report that TFAM deficiency rapidly and stably induced spontaneous lung metastasis in mice with liver cancer. Interestingly, unexpected polymerization of nuclear actin was observed in TFAM-knockdown HCC cells when cytoskeleton was examined. Polymerization of nuclear actin is causally linked to the high-metastatic ability of HCC cells by modulating chromatin accessibility and coordinating the expression of genes associated with extracellular matrix remodeling, angiogenesis, and cell migration. Mechanistically, TFAM deficiency blocked the TCA cycle and increased the intracellular malonyl-CoA levels. Malonylation of mDia2, which drives actin assembly, promotes its nuclear translocation. Importantly, inhibition of malonyl-CoA production or nuclear actin polymerization significantly impeded the spread of HCC cells in mice. Moreover, TFAM was significantly downregulated in metastatic HCC tissues and was associated with overall survival and time to tumor recurrence of HCC patients. Taken together, our study connects mitochondria to the metastasis of human cancer via uncovered mitochondria-to-nucleus retrograde signaling, indicating that TFAM may serve as an effective target to block HCC metastasis.

RNAseq of ATDC5 cells with mechanotransductive perturbations

Project description:Chondrocyte phenotype is preserved when cells are round and the actin cytoskeleton is cortical. Conversely, these cells rapidly dedifferentiate in vitro with increased mechanoactive Rho signaling, which increases cell size and causes large actin stress fiber to form. While the effects of Rho on chondrocyte phenotype are well established, the molecular mechanism is not yet fully elucidated. Yap, a transcriptional co-regulator, is regulated by Rho in a mechanotransductive manner and can suppress chondrogenesis in vivo. Here, we sought to elucidate the relationship between mechanoactive Rho and Yap on chondrogenic gene expression. We first show that decreasing mechanoactive state through Rho inhibition results in a broad increase in chondrogenic gene expression. Next, we show that Yap and its co-regulator Taz, are negative regulators of chondrogenic gene expression, and removal of these factors promotes chondrogenesis even in environments that promote cell spreading. Finally, we establish that Yap/Taz is essential for translating Rho-mediated signals to negatively regulate chondrogenic gene expression, and that its removal negates the effects of increased Rho signaling. Together, these data indicate that Rho is a mechanoregulator of chondrogenic differentiation, and that its impact on chondrogenic expression is exerted principally through mechanically-induced translocation and activity of Yap and Taz.

The epithelial cell transcriptome after alpha-toxin treatment

Project description:Responsiveness of cells to alpha-toxin (Hla) from Staphylococcus aureus appears to occur in a cell-type dependent manner. Here, we compare two human bronchial epithelial cell lines, i.e. Hla-susceptible 16HBE14o- and Hla-resistant S9 cells, by a quantitative multi-omics strategy for a better understanding of Hla-induced cellular programs. Phosphoproteomics revealed a substantial impact on phosphorylation-dependent signaling in both cell models and highlights alterations in signaling pathways associated with cell-cell and cell-matrix contacts as well as the actin cytoskeleton as key features of early rHla-induced effects. Along comparable changes in down-stream activity of major protein kinases significant differences between both models were found upon rHla-treatment including activation of EGFR and MAPK1/3 signaling in S9 and repression in 16HBE14o- cells. System-wide transcript and protein expression profiling indicate induction of an immediate early response in either model. In addition, EGFR and MAPK1/3-mediated changes in gene expression suggest cellular recovery and survival in S9 cells but cell death in 16HBE14o- cells. Strikingly, inhibition of the EGFR sensitized S9 cells to Hla indicating that the cellular capacity of activation of the EGFR is a major protective determinant against Hla-mediated cytotoxic effects. Design includes two different human bronchial epithelial cell lines, one control treatment (mock treatment for 2 hours) and one condition (2 alpha toxin treatment for 2 hours). Experiments for both cell line were replicated twice (biological replication).

Transcription profiling by array of human dendritic cells exposed to mesenchymal stem cells

Project description:All experiments are performed on human dendritic cells (DCs) differentiated in GM-CSF and IL-4 from CD14+ cells and bone marrow mesenchimal stem cells (MSCs). We found that MSCs impair active immune synapse formation and we evidenced at electron microscopy two types of contact between MSCs and DCs: gap and adherent junctions. In the same experiments we show that MSC contacts induce a reorganization of DC cytoskeleton by the formation of actin podosomes, structures typical of an immature, tolerogenic state of DCs. These results suggest that MSCs exert a tolerogenic effect on DCs by mechanism mediated by cell-cell contact. This induces DC cytoskeleton reorganization with formation of actin podosomes.
