Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
In the past decade, the relevance of tumor-induced lymphangiogenesis for the metastatic spread of tumor cells has been demonstrated, thus indicating the potential of targeting tumor lymphangiogenesis to treat cancer. Whereas numerous preclinical studies demonstrated that blocking angiogenesis or lymphangiogenesis could inhibit tumor metastasis, the scarcity of highly selective targeting candidates hampers their translation to the clinic.

- Affymetrix Drosophila Genome 2.0 Array (drosophila2)
Description
Regeneration of fragmented Drosophila imaginal discs occurs in an epimorphic manner, involving local cell proliferation at the wound site. Following disc fragmentation, cells at the wound site activate a restoration program through wound healing, regenerative cell proliferation and repatterning of the tissue. However, the interplay of signaling cascades, driving these early reprogramming steps, is not well understood. Here we profiled the transcriptome of regenerating cells in the early phase within twenty-four hours after wounding. We found that JAK/STAT signaling becomes activated at the wound site and promotes regenerative cell proliferation in cooperation with Wingless (Wg) signaling. In addition, we demonstrated that the expression of Drosophila insulin-like peptide 8 (dilp8), which encodes a paracrine peptide to delay the onset of pupariation, is controlled by JAK/STAT signaling in early regenerating discs. Our findings suggest that JAK/STAT signaling plays a pivotal role in coordinating regenerative disc growth with organismal developmental timing.
Publication Title

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Bone morphogenic proteins (BMPs) function in virtually all tissues with cell-type specific outcomes. Since there are a relatively small number of BMP receptors this exquisite signaling specificity requires additional molecules to regulate the output of this pathway. We demonstrated that the receptor tyrosine kinase MuSK that is selectively expressed in muscle and plays a critical role in synapse formation and maintenance binds to BMP4 and related BMPs. Since BMPs regulate the transcription of a set of genes, we performed microarrays for wild-type and MuSK null muscle cells to test if MuSK regulates BMP responses in muscle cells.
Publication Title
MuSK is a BMP co-receptor that shapes BMP responses and calcium signaling in muscle cells.

Description
Medulloblastoma (MB) is the most common malignant brain tumor in children, among whom overexpression or amplification of MYC oncogenes has been associated with poor clinical outcome. Although the MYC functions during normal development and oncogenesis in various systems have been extensively investigated, the transcriptional targets mediating MYC effects in MB are still elusive. Their identification and roles during MB onset and progression are important and will ultimately suggest novel potential therapeutic targets. cDNA microarray analysis was used to compare the effects of overexpressing and silencing MYC on the transcriptome of a MB-derived cell line. We identified 209 genes with potential relevance to MYC-dependent cellular responses in MB. Among the MYC-responsive genes, we found members of the bone morphogenetic protein (BMP) signaling pathway, which plays a crucial role during the development of the cerebellum. In particular, the cytokine gene BMP7 was identified as a direct target of MYC in MB cells. Similar to the effect induced by BMP7 silencing by siRNA, the use of a small-molecule inhibitor of the BMP/SMAD signaling pathway reduced cell viability in a panel of MB cells. Altogether, our findings indicate that high MYC levels drive BMP7 expression in MB to induce pro-survival and pro-proliferative cellular pathways. This observation suggests that targeting the BMP/SMAD pathway may be a new therapeutic concept for the treatment of childhood MB.
