Gene silencing describes the epigenetic regulation of a gene, at the level of transcription or translation, to prevent gene expression. Mechanisms include DNA methylation, histone modification and ...

Gene therapy involves the introduction of new genes into cells, to restore or add gene expression, for the purpose of treating disease. Most commonly a mutated gene is replaced with DNA encoding a ...

Here’s how it works. Scientists have discovered a gene variant that could make some parents more likely to have girls than boys. In the new study, researchers analyzed the genomes of around ...

By Gina Kolata Photographs by Kenny Holston Gina Kolata visited Kendric Cromer and his parents for the third time as she has followed his gene therapy at Children’s National Hospital in ...

The great scientist strays into speculation in The Genetic Book of the Dead, his latest defence of his “selfish gene” theory of evolution. By Tim Flannery Richard Dawkins is without doubt the most ...

We demonstrate that allelic expression arising from genetic or epigenetic differences is highly tissue-specific. We find that tissue-specific strain-biased gene expression may be regulated by ...
