- Illumina mouseRef-8 v1.1 expression beadchip
Description
Analysis of gene expression of prostate tumors arisen in TRAMP mice in which mast cells are pharmacologically stabilized or genetically ablated.The hypothesis tested in the present study was that mast cells inhibition or absence impacted prostate tumor development and histotype. Results demonstrate that prostate tumors arisen in TRAMP mice in which mast cells are pharmacologically stabilized or genetically ablated have a neuroendocrine signature.

Illumina mouseRef-8 v1.1 expression beadchip
Description
Analysis of gene expression of 2 novel prostate tumor cell lines isolated from TRAMP mice and compared to normal prostate. T1525 cell line is a well differentiated adenocarcinoma with epithelial features, whereas T23 cell line displays the molecular signature of epithelial-to-mesenchymal transition.

Description
Regulatory T (Treg) maintain the tumor microenvironment in an immunosuppressive state preventing effective anti-tumor immune response. A possible strategy to overcome Treg cell suppression focuses on OX40, a costimulatory molecule expressed constitutively by Treg cells while induced in activated effector T (Teff) cells. OX40 stimulation by the agonist mAb OX86 inhibits Treg cell suppression and boosts Teff cell activation. Here we uncover the mechanisms underlying the therapeutic activity of OX86 treatment dissecting its distinct effects on Treg and on effector memory T (Tem) cells, which are the most abundant CD4+ populations strongly expressing OX40 at the tumor site. In response to OX86, tumor-infiltrating Treg cells produced significantly less interleukin 10 (IL-10), possibly in relation to a decrease in the transcription factor IRF1. Tem cells responded to OX86 by upregulating surface CD40L expression, providing a licensing signal to dendritic cells (DCs). The CD40L/CD40 axis was required for Tem cell-mediated in vitro DC maturation and in vivo DC migration. Accordingly, OX86 treatment was no longer therapeutic in CD40 KO mice. In conclusion, following OX40 stimulation, blockade of Treg cell suppression and enhancement of the Tem cell adjuvant effect both concurred to free DCs from immunosuppression and to activate the immune response against the tumor.
