SAD genes identified in the body

摘要

New treatments for SAD - seasonal affective disorder - may be on the cards thanks to research from the Universities of Manchester and Edinburgh which discovered two genes that regulate the body clock. The genes - TAC1 and EYA3 - are activated early when natural hormone levels rise due to longer days. The study suggests TACl will only work with EYA3. EYA3 regulates TACl by switching it on in response to an increasing day length.
