Somatic copy number alterations are associated with EGFR amplification and shortened survival in patients with primary glioblastoma.

2019

Glioblastoma (GBM) is the most common malignant primary tumor of the central nervous system. With no effective therapy, the prognosis for patients is terrible poor. It is highly heterogeneous and EGFR amplification is its most frequent molecular alteration. In this light, we aimed to examine the genetic heterogeneity of GBM and to correlate it with the clinical characteristics of the patients. For that purpose, we analyzed the status of EGFR and the somatic copy number alterations (CNAs) of a set of tumor suppressor genes and oncogenes. Thus, we found GBMs with high level of EGFR amplification, low level and with no EGFR amplification. Highly amplified tumors showed histological features of…

Híbridos ibéricos de Helianthemum viscarium (Cistaceae)

2012

Helianthemum viscarium se distribuye por el norte de África y sudeste de la Península Ibérica, territorios en los que convive y se cruza con otros táxones de la sección Helianthemum. En la presente contribución se revisa la nomenclatura y taxonomía de los híbridos ibéricos de dicha especie. Por un lado, se propone aplicar el nombre H. x guiraoi Willk. a los ejemplares resultantes del cruzamiento entre H. almeriense subsp. scopulorum y H. viscarium, en un sentido diferente al que fue descrito; este híbrido se lectotipifica y se da a conocer como novedad para Alicante. Además, se discute un curioso enredo nomenclatural que afecta a los híbridos almerienses denominados en ocasiones H. x alican…
