gene expression

A study finds that expression levels of certain genes that track with brain activity—particularly those involved in brain development—vary between people with autism and their non-autistic peers.

The molecular biologist studies how chemical modifications to RNA building blocks change the way RNA regulates complex cellular processes.

In two related studies, researchers describe huge chromosomal rearrangements and about 500 novel gene clusters in the octopus, squid, and cuttlefish genomes, which they say could help explain how they evolved their extraordinary brains.

Human data and experiments in mice challenge the common use of anti-inflammatory drugs to treat pain.

A study in mice finds that for certain genes, one parent’s allele can dominate expression and shape behavior—and which parent’s allele does so varies throughout the body.

Rounds of trial-and-error exploring the layer of cells covering the ovary leave open questions about stem cells that are associated with ovarian cancer.

A handful of new studies moves the needle toward a consensus on the long-disputed question of whether insect wings evolved from legs or from the body wall, but the devil is in the details.

A study finds that a baculovirus that infects cotton bollworm larvae changes the expression of genes involved in light perception, driving them to seek heights that could favor viral transmission.

A new study has identified a molecular tradeoff between growth and immunity in moths in response to the administration of subtherapeutic doses of antibiotics, a common practice in animal husbandry.

A new method helps researchers uncover the rules of ribosome recruitment in yeast.

Genes lacking a particular structure known as CpG islands tend to go haywire in older cells, a study finds, potentially contributing to key facets of aging. But it’s not yet clear if the relationship is causal.

A study that transfused plasma from active to inactive mice suggests the protein clusterin enhances cognition.

Certain stretches of DNA that regulate gene expression have evolved differently from protein-coding genes.
