Sentences with phrase «by previous genetic studies»

The study involved participants of European descent exclusively, but co-author Roy Perlis, a researcher at Massachusetts General Hospital, notes it's standard method to focus on one group as a starting point, since previous research shows genetic markers can vary by ethnicity.

Although previous studies have found that a large percentage of hair colour variation is explained by heritable factors, previous genetic studies only identified a dozen or so hair colour genes.

Previous studies in the lab showed that once HCMV is inside the cell, it quickly becomes latent by entering the cell's nucleus and co-opting a cellular protein called Daxx — part of the intrinsic immune system — to shut down its own replication, the process of reproducing its genetic material to make more copies of itself.

The research team, following up on a previous genome - wide association study by researchers at Baylor College of Medicine, investigated genetic variations in a protein called FBN - 1, which is essential for a strong arterial wall.

Through previous studies, many led by our team at the ICR, this brings the total number of genetic variants known to be associated with testicular cancer to 25.

For example, previous reports have stated that genetic diversity in gerbil populations is relatively low, but these reports are biased by divergence in the «outbred» population being studied.

Dr Ricardo Rodríguez Varela, researcher at Stockholm University and lead author of the study, explains: «By generating the first autosomal genetic data from these populations we can conclusively demonstrate that the Guanches were most closely related to modern North Africans of Berber ancestry than to any other population we included for comparisons, supporting previous studies but adding more detail and nuance.»
