Researchers still do not have a comprehensive picture of the factors that influence gene expression in human cancers. Understanding gene expression in cancer is important because it can reveal how the ...

The course of human history has been marked by complex patterns of migration, isolation, and admixture, the latter a term that refers to gene flow between individuals from different populations.

There are a number of C. trachomatis gene products that exhibit variability and may modulate disease severity (Figure 3). The major categories of variable chlamydial gene products and their roles in ...

The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...

Humans were isolated in southern Africa for about 100,000 years, which caused them to "fall outside the range of genetic variation" seen in modern-day people, a new genetic study reveals. The finding ...

Knowing how human DNA changes over generations is essential to estimating genetic disease risks and understanding how we evolved. But some of the most changeable regions of our DNA have been ...
