Project description:In this data, we examined Transcriptome detection and expression in 8 samples of Retinoblastoma. We found a central core shared by all samples . We used exon arrays to find a detected and undetected transcripts and genes in Retinoblastoma and we compared unilateral and bilateral samples.

Project description:Transcriptome analysis of partially degraded and fragmented RNA samples from retinoblastoma primary tumors. Global gene expression profiling has shown great promise in high-throughput biomarker discovery for early disease detection in Retinoblastoma tumors. In this analysis we have used 3 retinoblastoma primary tumors in triplicates which was normalised against human healthy Retina. Here, we have used nanogram scale of retinoblastoma RNA, processed in HUMAN GENE 1.0 ST ARRAYS.

Project description:In order to identify the gene targets of frequently altered chromosomal regions in retinoblastoma, a meta-analysis of genome-wide copy number alterations studies on primary retinoblastoma tissue and retinoblastoma cell lines was performed. Published studies were complemented by copy number and gene expression analysis on primary and cell line samples of retinoblastoma. This dataset includes the gene expression data of the retinoblastoma cell lines

Project description:Genomic losses on chromosome 16q are among the most frequent alterations found in retinoblastoma. In this study, Affymetrix GeneChip analyses along with LOH analysis of microsatellie markers was used to identify candidate tumor suppressor loci in a set of retinoblastoma. We used microarrays to identify genes differentially expressed in retinoblastoma with LOH on 16q (M19484, M22590, M22641, M22860) compared to retinoblastoma without alterations in this region (M20517, M22067, M22233, M23209, M23449, M23818, M23896, M23978) Keywords: Disease progression

Project description:Lysyl oxidase (LOX) is an copper dependent amine oxidase enzyme involved in cross linking of collagens and elastins. Lysyl oxidase propeptide (LOX-PP) is 18 kDa region cleaved during maturation of LOX and its anti-tumorigenic role were studied in various cancers. The effect of LOX-PP overexpression in retinoblastoma cancer cells (Y79) using transient transfection of LOX-PP gene accessed for global gene deregulations. The analysis resulted in RB cancer cell death through deregulation of retinoblastoma in cancer, cell cycle, apoptosis, focal adhesion-PI3K-AKT signaling and DNA repair mechanism pathway. Further validations were done using RT-PCR and western blot analysis. Our results provide evidence that inducing apoptosis through AKT-NFκB signaling.

Project description:Retinoblastoma is a malignant tumor of the retina which most often occurs in children below 5 years of age with an incident rate of about 1 in 15,000 to 18,000 live births. Retinoblastoma is the first ever cancer that was reported to have a genetic basis. It occurs widely due to inactivating mutations in RB1 gene. Gene expression studies, copy number variation analysis, epigenetic profiling including miRNA and methylation of retinoblastoma has been carried to understand the disease mechanism and key players in the disease. Our group has earlier performed differential proteomics of retinoblastoma to identify proteins of therapeutic importance. However, there are no studies to understand the signalling mechanisms associated with retinoblastoma. Hence, global phosphoproteomics of retinoblastoma was carried out to identify signalling events associated with this cancer. Our study identified stress response proteins to be hyper phosphorylated which included H2AFX and sirtuin 1. In particular, Ser140 of H2AFX also known as gamma-H2AX was found to be hyperphosphorylated in retinoblastoma that indicated activation of DNA damage response pathways. We also observed activation of anti-apoptotic proteins in retinoblastoma compared to control. These observations showed activation of survival pathways and signalling networks activated in tumors.
