Evaluating the roles of testosterone and sex-linked genes in territorial aggression of sex-reversed XY females in the African pygmy mouse

This study investigates the molecular basis of territorial aggression in sex-reversed XY females of the African pygmy mouse, finding no correlation between aggression and testosterone or gene expression, but suggesting dopaminergic and oxytocin pathways may be involved.

Influence of gonadal and chromosomal sex on the brain transcriptome in a mouse species with natural sex reversal

The paper compares brain transcriptomes of four sexual genotypes in African pygmy mice to show that both gonadal and chromosomal sex influence gene expression, with X*Y females showing unique patterns linked to sex-linked genes.

Meiosis reveals the early steps in the evolution of a neo-XY sex chromosome pair in the African pygmy mouse Mus minutoides

This paper studies meiosis in the African pygmy mouse to reveal early steps in neo-XY sex chromosome differentiation, showing delayed synapsis, suppressed recombination, and unique metaphase-I associations in the neo-PAR.

Contrasting patterns of ERK activation in the tail of the striatum in response to aversive and rewarding signals

The paper investigates ERK activation in the tail of the striatum (TS) in response to various stimuli, finding that D1R-SPNs in specific subterritories are activated by psychostimulants but not hallucinogens.

Repeat associated mechanisms of genome evolution and function revealed by the Mus caroli and Mus pahari genomes

The paper compares genome assemblies of Mus caroli and Mus pahari with Mus musculus and Rattus norvegicus to reveal lineage-specific evolutionary mechanisms, particularly repeat-associated processes.
