Genetics of autoimmune diseases: insights from population genetics

Journal of Human Genetics, 2015
Human genetic diversity is the result of population genetic forces. This genetic variation influences disease risk and contributes to health disparities.

Genetic Sex and Origin Identification Suggests Differential Migration of Male and Female Atlantic Bluefin Tuna (Thunnus thynnus) in the Northeast Atlantic

Evolutionary Applications
Knowledge about sex‐specific difference in life‐history traits—like growth, mortality, or behavior—is of key importance for management and conservation as these parameters are essential for predictive modeling of population sustainability.

diveRsity: An R package for the estimation and exploration of population genetics parameters and their associated errors

, 2013
We present a new R package, diveRsity, for the calculation of various diversity statistics, including common diversity partitioning statistics (θ, GST) and population differentiation statistics (DJost, GST ' , χ2 test for population heterogeneity), among

Evolution of the genetic code. Emergence of stop codons [PDF]

arXiv, 2007
What could cause the emergence of non-encoding codons in the course of evolution of the genetic code? Hypothesis of evolution of the genetic code from GC to the AGUC-alphabet account for existence of stop codons.

MEGA3: Integrated software for Molecular Evolutionary Genetics Analysis and sequence alignment

Briefings Bioinform., 2004
With its theoretical basis firmly established in molecular evolutionary and population genetics, the comparative DNA and protein sequence analysis plays a central role in reconstructing the evolutionary histories of species and multigene families ...

Recent progress and challenges in population genetics of polyploid organisms: an overview of current state‐of‐the‐art molecular and statistical tools

Molecular Ecology, 2014
Despite the importance of polyploidy and the increasing availability of new genomic data, there remain important gaps in our knowledge of polyploid population genetics. These gaps arise from the complex nature of polyploid data (e.g. multiple alleles and

Genetic evidence of population structuring in the neotropical freshwater fish Brycon hilarii (Valenciennes, 1850)

Brazilian Journal of Biology
Brycon hilarii is a migratory fish widely distributed throughout the Paraguay River Basin. It is appreciated in sport fishing and for its superior meat quality. It is also the main species for tourist attraction in the Bonito region (State of Mato Grosso

A Comparative Meta‐Analysis on the Association of lncRNAs MALAT1, HOTAIR, and AFAP1‐AS1 With the Risk of Developing Lymph Node Metastasis in Lung Cancer

Cancer Reports
Background Numerous studies have demonstrated the significance of long noncoding RNA (lncRNA) in the development of cancer metastasis. The expression levels of many lncRNAs are elevated in metastatic lung cancer patients compared to non‐metastatic lung ...

Evolution of the genetic code from the GC- to the AGUC-alphabet [PDF]

arXiv, 2007
A hypothesis of the evolution of the genetic code is proposed, the leading mechanism of which is the nucleotide spontaneous damage leading to AT-enrichment of the genome. The hypothesis accounts for stability of the genetic code towards point mutations, the presence of code dialects, and the symmetry of the genetic code table.
