Oligodendrogliomas are the second most common malignant brain tumor in adults and exhibit characteristic losses of chromosomes 1p and 19q. To identify the molecular genetic basis for this alteration, we performed exomic sequencing of seven tumors. Among other changes, we found that the CIC gene (homolog of the Drosophila gene capicua) on chromosome 19q was somatically mutated in six cases and that the FUBP1 gene [encoding far-upstream element (FUSE) binding protein] on chromosome 1p was somatically mutated in two tumors. Examination of 27 additional oligodendrogliomas revealed 12 and 3 more tumors with mutations of CIC and FUBP1, respectively, 58% of which were predicted to result in truncations of the encoded proteins. These results suggest a critical role for these genes in the biology and pathology of oligodendrocytes.

El objetivo del texto es recuperar la intuición de Johan Georg Baiter (1801-‐‑1877) que propuso Tusculum (Lacio, Italia) como patria de origen de Marco Celio Rufo enmendando una corruptela en la edición orelliana del Pro Caelio ciceroniano. Esta conjetura, desestimada en todas las ediciones posteriores del texto, ha sido recientemente confirmada gracias al hallazgo de un epígrafe que documenta por vez primera en la ciudad lacial un magistrado M. Caelius de época tardorepublicana.

Circulating immune complexes (CIC) from 15 paracoccidioidomycosis (PCM) patient sera and from 20 healthy control sera were analysed. After CIC precipitation, solubilization and acid treatment, only a little reactivity to P. brasiliensis antigens was found in the free antibodies from PCM-CIC. This result has suggested that there were antibodies with a high affinity bound to fungus components. Dissociated CIC were fractionated in a column of Sephacryl S300 and the fractions that probably contained antigens were pooled and applied to an affinity column, prepared with mouse anti-gp43 monoclonal antibody. Using ECL-Western blotting assay two polypeptide with apparent mass of 43 and 62 kDa were found.

Nota sobre la Octava Reunion Anual de la Junta de Gobernadores de la Corporacion de Inversiones del Caribe (Caribbean Investment Corporation, CIC) realizada en Sta. Lucia, el 14 de mayo de 1982. Durante la reunion las discusiones se centraron fundamentalmente sobre el futuro de la CIC.

Mutations in the critical chromatin modifier ATRX and mutations in CIC and FUBP1, which are potent regulators of cell growth, have been discovered in specific subtypes of gliomas, the most common type of primary malignant brain tumors. However, the frequency of these mutations in many subtypes of gliomas, and their association with clinical features of the patients, is poorly understood. Here we analyzed these loci in 363 brain tumors. ATRX is frequently mutated in grade II-III astrocytomas (71%), oligoastrocytomas (68%), and secondary glioblastomas (57%), and ATRX mutations are associated with IDH1 mutations and with an alternative lengthening of telomeres phenotype. CIC and FUBP1 mutations occurred frequently in oligodendrogliomas (46% and 24%, respectively) but rarely in astrocytomas or oligoastrocytomas (<10%). This analysis allowed us to define two highly recurrent genetic signatures in gliomas: IDH1/ATRX (I-A) and IDH1/CIC/FUBP1 (I-CF). Patients with I-CF gliomas had a significantly longer median overall survival (96 months) than patients with I-A gliomas (51 months) and patients with gliomas that did not harbor either signature (13 months). The genetic signatures distinguished clinically distinct groups of oligoastrocytoma patients, which usually present a diagnostic challenge, and were associated with differences in clinical outcome even among individual tumor types. In addition to providing new clues about the genetic alterations underlying gliomas, the results have immediate clinical implications, providing a tripartite genetic signature that can serve as a useful adjunct to conventional glioma classification that may aid in prognosis, treatment selection, and therapeutic trial design.
