Identifican genes de algunos peces que se adaptan al cambio climático. El descubrimiento ayudará a identificar las especies más vulnerables y las más tolerantes ante los cambios en el medio ambiente EFEverde.- Un grupo de científicos ha identificado por primera vez los genes que permiten a ciertas especies de peces adaptarse al calentamiento de los océanos causado por el cambio climático, informó hoy la australiana Universidad James Cook.

En un comunicado, el centro afirmó que, en un proyecto conjunto con la saudí Universidad King Abdullah, los investigadores analizaron varias generaciones de peces en un experimento con coral en un laboratorio en el estado de Queensland (noreste australiano).

The faux-wrap style flatters every shape from curvy to slight, while the A-line skirt with darts along the waist comfortably provides plenty of flair. The rayon dress also features elbow-length sleeves and pleated shoulders. Approx. 49" long. Hand wash, line dry. Imported. Issues finalized policy on genomic data sharing. Policy’s implementation is key to accelerating biomedical discoveries The National Institutes of Health has issued a final NIH Genomic Data Sharing (GDS) policy to promote data sharing as a way to speed the translation of data into knowledge, products and procedures that improve health while protecting the privacy of research participants.

issues finalized policy on genomic data sharing

The final policy was posted in the Federal Register Aug. 26, 2014 and published in the NIH Guide for Grants and Contracts Aug. 27, 2014. Genomic Data Sharing Policy Starting with funding applications submitted for a Jan. 25, 2015, receipt date, the policy will apply to all NIH-funded, large-scale human and non-human projects that generate genomic data. This includes research conducted with the support of NIH grants and contracts and within the NIH Intramural Research Program.

The GDS policy can be traced to the Human Genome Project, completed in 2003, which required rapid and broad data release during its mapping and sequencing of the human genome.

Our genes determine the traces that stress leaves behind on our brains. Our individual genetic make-up determines the effect that stress has on our emotional centres.

Our genes determine the traces that stress leaves behind on our brains

These are the findings of a group of researchers from the MedUni Vienna. Not every individual reacts in the same way to life events that produce the same degree of stress. Some grow as a result of the crisis, whereas others break down and fall ill, for example with depression. The outcome is determined by a complex interaction between depression gene versions and environmental factors. The Vienna research group, together with international cooperation partners, have demonstrated that there are interactions between stressful life events and certain risk gene variants that subsequently change the volume of the hippocampus forever. The hippocampus is a switching station in the processing of emotions and acts like a central interface when dealing with stress.

Identificado un paso crucial en la reparación del ADN

(EUROPA PRESS) - Científicos de la Universidad Estatal de Washington, en Estados Unidos, han identificado un paso crucial en la reparación del ADN que podría conducir a una terapia génica dirigida para tratar enfermedades hereditarias como la que sufren los llamados "hijos de la luna" y una forma común de cáncer de colon, trastornos que son causados por sistemas de reparación del ADN defectuosos que aumentan el riesgo de cáncer y otras condiciones. Esta investigación, cuyos resultados se publican en 'Proceedings of the National Academy of Sciences' (PNAS) de esta semana, fue financiada por el Instituto Nacional de Ciencias de Salud Ambiental de Estados Unidos.

En concreto, sus autores hallaron que cuando se daña el ADN, se "desabrocha" una proteína específica de éste para permitir un fácil acceso del "equipo de reparación" del ADN. Cada célula humana soporta una serie de ataques que pueden generar hasta 100.000 lesiones de ADN todos los días, señala Smerdon. Genetic key to lupus shows potential of personalised medicine. (Medical Xpress)—Medical researchers have used DNA sequencing to identify a gene variant responsible for causing lupus in a young patient.

Genetic key to lupus shows potential of personalised medicine

The development shows that for the first time, it is feasible for researchers to identify the individual causes of lupus in patients by using DNA sequencing, allowing doctors to target specific treatments to individual patients. Lupus is a chronic autoimmune disease that affects one in 700 Australians, predominantly young and middle aged women. Medical researchers at the Centre for Personalised Immunology, based at the John Curtin School of Medical Research (JCSMR), sequenced the genes of a young girl who suffered a stroke when she was four as a result of her lupus.

"We can now target her specific disease, and make treatments that will benefit her throughout her life," said lead researcher Dr Julia Ellyard, from the JCSMR. Researchers identified a variant in the TREX1 gene. "This is the new age of personalised medicine," she said.
