The inhibition of PKC by Go6976 prior to TLR3 stimulation leads to an ablation of expression of IRF-3-dependent genes. Total RNA extracted from HT1080 cells with or without 1 h pretreatment with 5 uM Go6976, after 6 h of treatment with dsRNA (polyIC), compared to untreated controls

Project description:A variety of airborne pathogens can induce inflammatory responses in airway epithelial cells, which is a crucial component of host defence. However, excessive inflammatory responses and chronic inflammation also contribute to different diseases in the respiratory system. We hypothesized that the activation of protein kinase C (PKC) is one of the essential mechanisms of inflammatory responses in airway epithelial cells. In the present study, we stimulated human bronchial lung epithelial (BEAS-2B) cells with phorbol ester Phorbol 12, 13-dibutyrate (PDBu), and examined gene expression profile with microarray analysis. Bioinformatics suggested that PKC activation induced dramatic changes in gene expression related to multiple cellular functions. The top two functional networks of genes were centered on NFM-NM-:B and TNF-M-NM-1, which are two commonly known pathways for cell death and inflammation. Subsequent tests confirmed the decrease in cell viability and increase in the production of various cytokines. Interestingly, each of the increased cytokines was differentially regulated at mRNA and/or protein levels by different sub-class of PKC isozymes. We conclude that many pathogen-induced cell death and cytokine production in airway epithelial cells may be mediated through PKC related signaling pathways. These findings suggest that PKCs can be new targets for treatments of lung diseases. Three groups of BEAS-2B cells were prepared: control, 0.5 hour of PDBu stimulation, and 4 hours of PDBu stimulation. Each group consisted of three biological replicates.

Project description:The objective of this study is to study the Toll-like receptor 3 (TLR3)-dependent gene expression in human fibroblast cells and peripheral blood mononuclear cells (PBMCs) Fibroblast cells and PBMCs from donors with autosomal recessive (AR) complete TLR3 deficiency and autosomal dominant (AD) partial TLR3 deficiency were collected for microarray analysis to measure the transcriptional responsiveness of TLR3 in fibroblast and PBMCs. A total of 3 healthy controls, 1 AD TLR3-deficient patient, 1 AR TLR3-deficient patient, 1 AR UNC-93B-deficient patient, 1 MyD88 deficient patien were used in this study. The fibroblast cells were cultured in DMEM medium supplemented with 10% fetal calf serum (FCS). The PBMCs were cultured in RPMI medium complemented with 10% FCS. Different kinetics (2 hours and 8 hours) of poly(I:C) (25ug/ml, purchased from Amersham) stimulations were performed, aiming to define TLR3-inducible genes in these human cells. A stimulation of IL-1β (20ng/ml, purchased from R&D system Inc.) was used as a positive activation control with same kinetics of stimulations. A total of one million cells per stimulation were used for fibroblasts, and around 1.5 million cells per stimulation for PBMCs.

Project description:we assessed the impact of TLR3 L412F at endogenous cellular levels upon double stranded RNA (dsRNA) stimulation, by performing RNA-sequencing in primary fibroblasts from individuals homozygous for the ancestral allele (n =2) or homozygous for TLR3 L412F (n = 4) upon extracellular Poly(I:C) stimulation that activates the TLR3 pathway. The average response of TLR3 L412F homozygotes was significantly decreased (mean Δ log2 fold-change = 0.93; Wilcoxon p <10-16) compared to that of cells with the ancestral allele, approaching that of TLR3-deficient cells, used as negative control.

Project description:The breast tumour microenvironment (TME) includes fibroblasts, adipocytes, inflammatory and immune cells. While treatment of tumours with chemotherapeutic agents such as Docetaxel, leads to apoptosis of tumour cells, it can also have consequences for the cellular makeup and transcriptional profile of the TME and these, like increased epithelial mesenchymal transition can promote undesirable consequences, such as Cancer Stem Cell development. PKC-theta may have a role in these undesired effects. To be able to examine the effects of co-treatment of Docetaxel with an inhibitor of PKC-theta, we performed RNA-seq on tumours from mice injected with the human breast cancer cell line MDA-MB-231. We then separated reads mapped to the human and mouse genomes in silico, creating tumour and TME transcriptomes for control, Docetaxel, PKC-theta inhibitor and combination treated mice. Separation of the tumour and TME profiles illustrated a role for PKC-theta in the induction of a more basal-type transcriptome in the tumour, and of EMT in the TME.

Project description:Human neuroblastoma cells (SH-SY5Y) were engineered to have stable expression of either TrkA (NTRK1) or TrkB (NTRK2) receptors. The cells were pretreated with 0.5 μM Trametinib, 2.5 μM Gefitinib, and combination of 0.25 μM Trametinib and 1.25 μM Gefitinib. Stimulation of TrkA and TrkB-expressing SH-SY5Y cells was carried out 30 minutes following inhibitor addition, using 100 ng/mL of recombinant NGF (#450-01) and BDNF (#450-02), respectively (both from Peprotech). The stimulated and unstimulated controls are included.
