Research lines. B-cell lymphomas functional analysis. Almost 200 B-cell lymphomas 8 clinical subtypes Clustering analysis 12
Research lines. B-cell lymphomas functional analysis. Gene Set Enrichment Analysis of NFKB pathway genes in Follicular and Burkitt Lymphomas using Biocarta annotations. Figure 1. Applying Kolmogorov-Smirnof test to find assymmetries in expression levels of functional related blocks of genes, NFKB pathway genes was found enriched in Follicular lymphomas in comparison to Burkitt lymphomas. Figure 2. Heatmap for expression values of those genes involved in NFKB pathway. Figure 3. Map of interactions for NFKB pathway related genes. Figure 3 Figure 1 Figure 2 13
Research lines. B-cell lymphomas transcriptome. Clustering the behaviour of whole pathways in B-cell lymphomas. 14
Research lines. Genetic Instability in Ewing Sarcomas. -Gene Set Enrichment Analysis of Cytobands and Pathways in Ewing Sarcomas.. Confirmed gains in chromosomes 5, 8,13,14,18 by enrichment analysis. Based on CNA and expression profiling we found G2 pathway, TNFR2, ATBRCA and other pathways enriched in stable vs unstable (3 or more aberrations) phenotypes. - Statistical multivariate analysis support the statistically significant relationship between genetic stability and survival of patients.
