Description
SPC2996 is a novel locked nucleic acid (LNA) phosphorothioate antisense molecule targeting the mRNA of the Bcl-2 oncoprotein. We investigated the mechanism of action of SPC2996 and the basis for its clinically observed immunostimulatory effects in chronic lymphocytic leukemia (CLL). Patients with relapsed CLL were treated with a maximum of six doses of SPC2996 (0.2-6mg/ kg) in a multicenter phase I trial. Microarray-based transcriptional profiling of circulating CLL cells was carried out before and after the first infusion of SPC2996 in eighteen patients.
Publication Title

- Affymetrix Human Genome U133A Array (hgu133a)
Description
Doxorubicin is considered one of the most potent established chemotherapeutics in the treatment of liposarcoma; however, the response rates usually below 30%, are still disappointing. This study was performed to identify gene expression changes in liposarcoma after doxorubicin treatment. Cells of 19 primary human liposarcoma were harvested intraoperatively and brought into cell culture. Cells were incubated with doxorubicin for 24 h, RNA was isolated and differential gene expression was analysed by the microarray technique.
Publication Title
Heterogeneous in vitro effects of doxorubicin on gene expression in primary human liposarcoma cultures.

Description
The cellular microenvironment in classical Hodgkin lymphoma (cHL) is dominated by a mixed infiltrate of inflammatory cells with typically only about 1% Hodgkin and Reed/Sternberg (HRS) tumor cells. T cells are usually the largest population of cells in the cHL microenvironment, encompassing T helper (Th) cells, regulatory T (Treg) cells and cytotoxic T cells. Th and Treg cells presumably provide essential survival signals for HRS cells. Treg cells are also involved in rescuing HRS cells from anti-tumor immune responses. An understanding of the immune evasion strategies of HRS cells is not only highly relevant for a characterization of the pathophysiology of cHL, but also clinically, given the current treatment approaches targeting checkpoint inhibitors. Here, we characterized the cHL-specific CD4+ T cell infiltrate regarding its role in immune evasion. Global gene expression analysis of CD4+ Th and Treg cells isolated from cHL lymph nodes and reactive tonsils revealed that Treg cell signatures were enriched in CD4+ Th cells of cHL. Hence, HRS cells may induce a Treg differentiation in Th cells, which was supported by in vitro studies with Th cells and cHL cell lines. Furthermore, we found indication for immune-suppressive purinergic signaling and a role of the inhibitory receptor-ligand pairs BTLA-HVEM and CD200R-CD200 in promoting immune evasion. Taken together, this study reveals that the immune evasion strategies in cHL are even more complex and multifaceted than previously recognized.

Description
We used microarrays to investigate differential gene expression in different thyroid hormone receptor beta mouse models. Hypothyroid wild type, TRbeta KO and TRbeta GS mutant mice were treated with T3 or vehicle alone. Microarray analysis revealed that the gene expression pattern in TRbeta GS mutant mice was similar to that in TRbeta KO mice.

- Affymetrix Mouse Expression 430A Array (moe430a)
Description
For generation of pre-B cell lines, bone marrow from tibias and femurs of 4 to 8 week old C56Bl/6 mice (wt and vav-Gfi1b transgene) was infected with retroviral stocks of different BCR-Abl constructs (MSCV-GFP-IRESp210 or pSRa-p210-tkneo) and plated at a density of 5E+06 per 6 cm dish. All pre-B cells were fed twice a week and analyzed after they became stroma independent. Cells received 1E-08 M dexamethasone or vehicle for 12 hours prior to RNA extraction using TRIzol. mRNAs were converted into doublestranded cDNA using a T7-promoter tagged oligodT primer and transcribed by T7 RNA polymerase in the presence of biotinylated NTPs. Targets were hybridized to Affymetrix MOE430A arrays, washed, stained and scanned (GeneChip scanner 2500) as recommended by the manufacturer. Images were processed either by MAS5.0 (global scaling, TGT=1000) or RMAExpress (quantile normalization and background substraction) software tools.
