Molecular targeted compounds are emerging as important component to improve the efficacy of classical chemotherapeutics. In this study, we tested whether using low dose sorafenib to reduce off target inhibitions of kinases impacts the antitumor effect of alkylating agents in breast cancer models. Overall design: MDA-MB231 cells were treated with 1 µM sorafenib, 40 µg/mL MMS, or pre-incubated with 1 µM sorafenib for 12 h followed by 40 µg/mL MMS, each in two independent experiments. RNA was harvested 8 and 24 h, or post MMS treatment for combination treatment.
Sorafenib improves alkylating therapy by blocking induced inflammation, invasion and angiogenesis in breast cancer cells.

View SamplesWe analyzed gene expression in CD4+ cells sorted from naïve or D30 Mycobacterium tuberculosis-infected mice and incubated in vitro in the presence or absence of Schistosoma egg antigen. We found genes associated with Th1 function, T cell signaling, T cell costimulation and T cell activation were downregulated in SEA-treated cells, while expression of Th2 cytokines was below the threshold for detection. Overall design: RNAseq results for 3 replicates for naïve or CD4+ T cells from M.tuberculosis-infected mice treated with or without Schistosoma egg antigen in vitro.

View SamplesWe hypothesized that gene expression in lungs of Fra-1+/+ and Fra-1-/- mice are divergent thus contributing fibrosis. More specifically, Fra-1-/- mice are increased susceptible to fibrosis. In order to test these hypotheses at the gene expression level, we utilized microarray analysis to examine transcriptional differences between Fra-1+/+ and Fra-1-/- mice at early time point.

View SamplesHuman prostate CWR22 OT-tumor cells were prospectively purified for expression of various stem cell markers (TRA-1-60/CD151/CD166/EpCAM/CD44/2-Integrin). Unsorted total tumor cells or the additional marker positive cells that do not manifest stem-like characteristics were used as control. All these cells were subjected to molecular profiling of total RNA expression and the fold change data are tabulated according to S/TFE of the purified cells in relation to their control.

View SamplesObjective: Conflicting evidence exists regarding the suppressive capacity of Tregs from the peripheral blood (PB) of patients with rheumatoid arthritis (RA). Our aim was to determine whether Tregs are intrinsically defective in RA using a wide range of read-out assays. Methods: CD3+CD4+CD25+CD127low Tregs from CD45RO+ and CD45RA+ compartments of PB from patients with RA and healthy controls (HC) were analysed for phenotype, cytokine expression profile (ex vivo and after in vitro stimulation), suppression of effector T-cell proliferation and cytokine production, suppression of monocyte-derived cytokine/chemokine production, and gene expression profiling. Results: No differences were observed between patients with RA and HC regarding Treg frequency, ex vivo phenotype (CD4, CD25, CD127, CD39, CD161) or pro-inflammatory cytokine profile (IL-17, IFN-gamma, TNF-alpha). FOXP3 expression was increased in Tregs from RA blood. The ability of Tregs to suppress T-cell proliferation or cytokine (IFN-gamma, TNF-alpha) production upon co-culture with autologous CD45RO+ effector T-cells and monocytes was not significantly different between patients with RA and HC. CD45RO+ Tregs from RA blood showed a slightly impaired ability to suppress production of some cytokines/chemokines by autologous LPS-activated monocytes (IL-1-beta, IL-1Ra, IL-7, CCL3, CCL4), but this was not true for all patients and other cytokines/chemokines (TNF-alpha, IL-6, IL-8, IL-12, IL-15, CCL5) were suppressed in the majority of patients similarly to HC. Finally, gene expression profiling of CD45RA+ or CD45RO+ Tregs from PB revealed no statistically significant differences between patients with RA and HC. Conclusions: Our findings suggest that Tregs isolated from PB of patients with RA are not intrinsically defective.
