The social amoeba Dictyostelium discoideum employs a terpene synthase-cytochrome P450 metabolic gene cluster to produce a novel trisnorsesquiterpene discodiene.
The small molecule, 147, is a pro-drug that preferentially activates ATF6 signaling through a mechanism involving localized metabolic activation and selective covalent modification of ER resident proteins involved in regulating ATF6 activity.
The hypoxia-inducible factor HIF drives transcription of the gene cyp-36A1, which encodes a cytochrome P450 enzyme that acts via a putative intercellular signal to regulate the nuclear receptor NHR-46 and consequently stress resistance and behavior.
Human chemically induced liver progenitors (hCLiPs), which are generated from primary human hepatocytes, exhibit the potential to repopulate injured livers of host mice with efficiency > 90%.
Age-dependent changes in DNA methylation are tightly coupled to the metabolic state, and is partly under genetic regulation, and longer lifespan is associated with lower epigenetic entropy at CpGs that increase in methylation with age.
The first genomic view of beetle luciferase evolution indicates evolutionary independence of luciferase between fireflies and click-beetles, and provide valuable datasets which will accelerate the discovery of new biotechnological tools.
Airborne PM2.5 exposure triggers oxidative stress and mitochondrial apoptosis in placental trophoblast cells via the KLF9/CYP1A1 transcriptional axis, ultimately leading to adverse pregnancy outcomes.

Genome wide association analyses in a wild-derived Drosophila melanogaster population uncover extensive variation in cuticular hydrocarbon composition, which may present a target for natural selection and adaptive evolution.
