Molecular and cytogenetic characterization of expanded B-cell clones from multi...
Henriques, A; Rodriguez-Caballero, A; Criado, I; Langerak, AW; Nieto, WG; Lecrevisse, Q; Gonzáles, M; Cortesão, E; Paiva, A; Almeida, J; Orfão, AChronic antigen-stimulation has been recurrently involved in the earlier stages of monoclonal B-cell lymphocytosis, chronic lymphocytic leukemia and other B-cell chronic lymphoproliferative disorders. Among these individuals, expansion of ≥2 B-cell clones has been frequently reported; potentially, such coexisting clones have a greater probability of interaction with common immunological determinants. Here, we c...
Amplified and Homozygously Deleted Genes in Glioblastoma: Impact on Gene Expres...
Crespo, I; Tão, H; Nieto, AB; Rebelo, O; Domingos, P; Vital, AL; Patino, MC; Barbosa, MD; Lopes, MC; Resende de Oliveira, C; Orfão, A; Tabernero, MDBACKGROUND: Glioblastoma multiforme (GBM) displays multiple amplicons and homozygous deletions that involve relevant pathogenic genes and other genes whose role remains unknown. METHODOLOGY: Single-nucleotide polymorphism (SNP)-arrays were used to determine the frequency of recurrent amplicons and homozygous deletions in GBM (n = 46), and to evaluate the impact of copy number alterations (CNA) on mRNA levels of...
Intratumoral patterns of clonal evolution in gliomas
Vital, AL; Tabernero, MD; Crespo, I; Rebelo, O; Tão, H; Gomes, F; Lopes, MC; Orfão, AFew studies have explored the patterns of clonal evolution in gliomas. Here, we investigate the cytogenetic patterns of intratumoral clonal evolution of gliomas and their impact on tumor histopathology and patient survival. Cytogenetic analysis of 90 gliomas was performed in individual tumor cells (>200 cells/tumor) using multicolor (N = 16 probes) interphase-FISH. Overall, chromosome gains were more frequent t...
