ÿþOver-expression of EGFR puma rs x toys and EGFRvIII is a major hallmark of GBM. Although, both receptors have been linked to GBM resistance to chemotherapy, the mechanisms underlying this association are still unclear. Our findings in this study provide evidence that both EGFR and EGFRvIII negatively regulate intrinsic mitochondria-mediated apoptosis by binding to PUMA, a proapoptotic protein that is highly expressed in the majority of GBM. Following the interactions of EGFR/EGFRvIII with PUMA, PUMA is sequestered in the cytoplasm, leading to impaired apoptotic response in GBM. Our results also demonstrate that EGFR/EGFRvIII-mediated antagonism of PUMA is independent of EGFR/EGFRvIII kinase activity and thus, may define a novel mechanism of tumor resistance to apoptosis-inducing EGFR inhibitors.
Future investigation is thus needed to identify these mechanisms in order to augment the apoptotic effects of anti-GBM therapy.The functional interaction between EGFR/EGFRvIII and PUMA potentially represents a new class of protein-protein interaction that involves a receptor tyrosine kinase and a proapoptotic protein. It is well known that EGFR can engage in protein-protein interactions puma cali with a variety of proteins, including, transcription factors, STAT3 [ 43 ], STAT5 [ 44 ] and E2F1 [ 45 ], DNA-dependent protein kinase [ 46 ], and the DNA replication and damage repair protein PCNA [ 47 ]. EGFR-STAT3 interactions lead to transcriptional activation of several cancer-related genes, including, inducible nitric oxide synthase [ puma rs x toy 34 ], TWIST [ 48 ] and COX-2 [ 49 ].

Timed location data from a network of 119 trap stations in the Cockscomb Basin of Belize provide the 1st evidence of interspecific avoidance calibrated against intraspecific interactions among jaguars.
Camera trapping has advantages over radiotelemetry in its potential to provide data on the complete array of individuals within the study area. The 23 individually identified male jaguars showed high levels of overlap in ranges, with up to 5 different males captured at the same location in the same month. Low levels of avoidance between individuals and a high flux of individuals contributed to low consistency in home-range ownership over the long term (3 months to 2 years). Jaguars and pumas had similar nocturnal activity schedules. Both species used similar habitats within the Cockscomb Basin, indicated by a high correlation in capture rates per location between species. Apart from their overall spatial similarities, jaguars and pumas avoided using the same location at the same time. This interspecific segregation was detectable over and above the spatial and temporal segregation of individual jaguars.
Registramos baja consistencia en las áreas de actividad ("home ranges") en períodos de 3 meses a dos años, con bajos niveles de separación espacial entre individuos pero con un alto flujo de individuos. Los patrones de actividad nocturna de jaguares y pumas fueron similares. Ambas especies usaron hábitats similares en la cuenca del Cockscomb, indicado por una alta correlación puma suede en las tasas de captura por sitio entre las especies. A pesar de estos patrones, los jaguares y pumas evitaron usar el mismo sitio al mismo tiempo. Esta segregación interespecífica fue detectada sobre la segregación espacial y temporal de los individuos de jaguar.In the present study we employ this longer ND5 segment to investigate the evolutionary history of P. concolor , with emphasis on South American populations, which were previously found to harbor high levels of diversity and inferred to have played a key role in the historical demography of [img]http://www.bargansa.com/images/red/puma suede-416fwm.jpg[/img] this species ( Culver et al. , 2000 ). |
