Inspection: The results of the identification of possible handling strategies – (Information)

Scientists at the National Eye Institute managed collaborative research and did not. including gene related to age-related macular erosion (AMD), the main cause of blind and blind vision among people aged 65 and over. These results provide a broader and deeper picture of the genetic contributions to AMD, and they are. introduces new routes for medical improvement. The inspection was published on February 11th Natural GeneticsSouth Westerly

"If we were to carry out criminal investigation, in advance of a number of local crimes, 52 streets in 34 zip code would have been investigated in advance. These latest results suggest suspicion real direct targets that we can do more closely, "said Chief Inspector Anand Swaroop, Ph.D., NEI's head of Neurobiology-Neurodegeneration and Laboratory Repair at NEI, National Health Institutions.

Previously, Swaroop and colleagues compared the numbers of people with and without AMD and identified 34 small genomic categories – known as loci – and 52 different genealogies within those loci that were highly co- related to AMD. "But, like other common and complicated infections, most of the changes did not appear in the genome protein courier sections, which left us to be Amazing how they had a biological impact on AMD, "said Swaroop.

The researchers investigated whether the adaptations of AMD's appropriate gaming modes could be managed, and possibly promoters, which constitute a sequence within DNA that can be used; turn on a gene, or increase, which maximizes promotional activity. If the changes were indeed the regulation of gene genealogy, The main question remained: what generations did the changes change?

The Swaroop team examined 453 retina, its impact; AMD has made eye glaze from human donors who died with and without AMD. The analysis included being & # 39; Keeping out all ribonucleic (RNA) reins, the molecule of a messenger that conducts DNA guidance to do it; printer making. There were 13,662 protein coding and a total of 1,462 RNA ruffles were identified as a whole without a presidential code.

To investigate the genetic changes that rule the sentence of a gene in the retina, they use a detailed species loci analysis (eQTL). Computing procedures allowed researchers to find patterns between the genealogies expressed in the retina and a collection of more than 9 million genres previously mentioned. In particular, they were looking for changes with great likelihood that they were responsible for changes in talking generation among people with and without AMD. The study stressed the trigger of a disease of six of the 34 AMD loci identified in the previous research.

In addition, the integration of this data with AMD audits identified earlier three additional AMD target genera, which had not previously been shown to participate in AMD. This analysis also praised as well as 20 seconds of additional candidates who; gives an overview of the genes and pathways involved in AMD psychology.

"To date, most studies in AMD have focused on genetic DNA checks. This study is for the first time to provide data transcript (RNA) for the expansion of the AMD genetic architecture, "said Rinki Ratnapriya, Ph.D., who was working as a researcher at NEI and is currently at Baylor College of Medicine Houston.

Among the genes the most incredible target was B3GLCT and BLOC1S1, which could impact on cell functions linked to AMD such as signals; breakdown and find out of unwanted prototypes; and the sustainability of an out-of-school matrix, the infrastructure of the cells to be distributed.

"Importantly, the ability to explain how a genetic difference affects the gene display and the opening of completely new instructions to look at the biology of the eye, "said Swaroop.

The analysis of the Swaroop development was essential in a database of retinal genealogy meaning. EyeGEx is the database that provides a resource for visual researchers, not just for AMD checks, but to investigate the genetic causes of other diseases such as diabetic retinopathy and glaucoma.

Integrated disease in AMD is still a combination of genetic understanding and behavioral understanding. Smoking, for example, is to improve the risk of the disease, while & # 39; It is eating green plants and reducing fish. Further research is needed to understand how these environmental factors interact with gene to enhance the development of their disease and its problem.

Future surveys will aim to analyze the action of the AMD target genera to find out how they are going to do; apply to the AMD pathology and to look for targets for new handling strategies.
