This study examines gene regulation changes during development in cichlid fishes, finding species-specific expression patterns linked to trophic niche adaptation.

The paper shows that alternative splicing evolves faster than gene expression in African cichlids, contributing to rapid ecological diversification during adaptive radiation.

The paper investigates density-dependent gene expression in Atlantic salmon hypothalamus, finding significant changes in stress, appetite, and epitranscriptomic genes, with unexpected paralogue patterns and genotype-environment interactions.

The paper uses MeRIP-seq to detect temperature-related variation in methylated environmental RNA from fish, identifying eRNAs associated with thermal stress response.

This study analyzes transcriptomes of Atlantic salmon gonad and pituitary tissues to identify novel genes and lncRNAs involved in sexual maturation and their regulatory roles.

The paper investigates how hybridization contributes to adaptive radiation in Lake Victoria cichlids by analyzing genotype-phenotype associations across multiple traits.

This study investigates how vgll3 alleles influence testicular gene expression patterns and heterochrony in Atlantic salmon, showing accelerated spermatogenesis in vgll3*EE individuals.

The paper investigates how vgll3 genotype and sex influence adipose dynamics and maturation age in Atlantic salmon through gene expression analysis in brain, adipose tissue, and gonads.

This study examines how genetic variation in vgll3 affects maturation age in Atlantic salmon, showing sex- and context-dependent expression patterns and interactions with other genes.

This study identifies genetic and molecular mechanisms in Atlantic salmon brains associated with early maturation, linking the Hippo pathway to reproductive timing.

The paper identifies a gene regulatory network in Atlantic salmon linking vgll3 to regulators of sexual maturation, suggesting alternative mechanisms to GnRH1 in controlling c-jun and sf1 expression.

The paper investigates m6A RNA methylation gene expression in Atlantic salmon hypothalamus, finding differential expression of m6A reader and eraser genes associated with sexual maturation timing.
