Monozygotic twins: genes are not the destiny?
Monozygotic twins are considered to be genetically identical, yet can show high discordance in their phenotypes and disease susceptibility. Several studies have emphasized the influence of external factors and the role of epigenetic polymorphism in conferring this variability. However, some recent high-resolution studies on DNA methylation show contradicting evidence, which poses questions on t...
متن کاملWhy genes aren't destiny.
The remote, snow-swept expanses of northern Sweden are an unlikely place to begin a story about cutting-edge genetic science. The kingdom's northernmost county, Norrbotten, is nearly free of human life; an average of just six people live in each square mile. And yet this tiny population can reveal a lot about how genes work in our everyday lives. Norrbotten is so isolated that in the 19th centu...
متن کاملP30: Are There Anxious Genes?
Anxiety comprises many clinical descriptions and phenotypes. A genetic predisposition to anxiety is undoubted; however, the nature and extent of that contribution is still unclear. Extensive genetic studies of the serotonin (5-hydroxytryptamine, 5-HT) transporter (5-HTT) gene have revealed how variation in gene expression can be correlated with anxiety phenotypes. Complete genome-wide linkage s...
متن کاملHox genes are not always Colinear
The deuterostomes are the clade of animals for which we have the most detailed understanding of Hox cluster organisation. With the Hox cluster of amphioxus (Branchiostoma floridae) we have the best prototypical, least derived Hox cluster for the group, whilst the urochordates present us with some of the most highly derived and disintegrated clusters. Combined with the detailed mechanistic under...
متن کاملConservation biology: Genes are not enough
A study of correlated genotypic and phenotypic changes over a 2400-year period in a cave population of pocket gophers bolsters the idea that small, isolated populations can not only persist in a fluctuating environment, but may be able to adapt without genetic input from elsewhere.
