(Submitter supplied) To identify signaling pathways that are differentially regulated in human gliomas, a microarray analysis on 30 brain tumor samples (12 primary glioblastomas (GBM), 3 secondary glioblastomas (GBM-2), 8 astrocytomas (Astro) and 7 oligodendrogliomas (Oligo)) and on 5 glioblastoma cell lines (LN018, LN215, LN229, LN319 and BS149) was performed. Normal brain tissue (NB) and normal human astrocytes (NHA) were used as a control. more...

(Submitter supplied) There is growing evidence that uncontrolled activation of the PI3K/Akt/mTOR pathway contributes to the development and progression of breast cancer. Inhibition of this pathway has antitumour effects in preclinical studies and efficacy in combination with other agents in breast cancer patients. The aim of this study is to characterise the effects of pre-operative everolimus treatment in primary breast cancer patients and to identify potential molecular predictors of response. more...

(Submitter supplied) Glioblastoma multiforme is one of the most devastating cancers and presents unique challenges to therapy due to its aggressive behaviour. Cancer stem cells have been described to be the only cell population with tumorogenic capacity in glioblastoma. Therefore, effective therapeutic strategies targeting these cells may be beneficial. We have established different cultures of glioblastoma stem cells (GSCs) derived from surgical specimens and found that, after induction of differentiation, NFκB was activated, which allows intermediate tumor precursor cells to remain cycling. more...

(Submitter supplied) Arsenic trioxide (ATO) treatment leads to activation of mRNA translation through the MAPK-interacting kinase (MNK) signaling pathway. Polysomal fractionation and microarray analysis allows for identification of transcripts undergoing active translation. We identified the genes differentially enriched in untreated and ATO treated fractions. In this dataset, we include expression data in untreated and ATO treated LN229 cells using either the total or polysomal RNA.

(Submitter supplied) TGF-beta is one of the key cytokines implicated in various disease processes including cancer. TGF-beta inhibits growth and promotes apoptosis in normal epithelial cells and in contrast, acts as a pro-tumour cytokine by promoting tumour angiogenesis, immune-escape and metastasis. It is not clear if various actions of TGF-beta on normal and tumour cells are due to differential gene regulations. Hence we studied the regulation of gene expression by TGF-beta in normal and cancer cells. more...

(Submitter supplied) ABSTRACT: Background: Oral Submucous Fibrosis (OSF) is a chronic inflammatory disease resulting in progressive fibrosis of the oral soft tissues. Habit of chewing betel quid has been proposed as an important etiological factor in the development of this disease. But the exact mechanism of pathogenesis is still not clear. Methods: We took microarray approach to identify differentially regulated genes in 10 OSF tissues against 8 pooled normal tissues using oligonucleotide arrays. more...

(Submitter supplied) Purpose: Gene expression analyses comparing tumors of different behaviors have been used for the identification of genes that have a role in the growth and maintenance of tumors, with the aim of both understanding the molecular basis of tumorigenesis and identifying novel potential therapeutic targets. We have here used this approach to identify the underlying gene expression differences between highly invasive glioblastoma multiforme and typically benign pilocytic astrocytomas. more...

(Submitter supplied) We want to investigate the transcriptional differences between pBABE D4m.3a melanoma cells (cancer cell control) and caMNK D4m.3a melanoma cells (cancer cells with constitutive activation of MNK) to find the transcriptional changes in melanoma cells upon MNK overexpression. This study allows us to examine the role MNK has in regulating key oncogenic factors involved in melanoma metastasis, proliferation and tumor development.

(Submitter supplied) Pain sensing neurons, nociceptors, are key drivers of neuropathic pain. We used translating ribosome affinity purification (trap) to comprehensively characterize up- and down-regulated mRNA translation in Scn10a-positive nociceptors in chemotherapy-induced neuropathic pain. We provide evidence that an underlying mechanism driving these changes in gene expression is a sustained mTORC1 activation driven by MNK1-eIF4E signaling. more...
