European Journal of Entomology, 2018 The sex determination cascades in insects are diversified at the top of the cascade, where different primary molecular signals are employed, while at the bottom of the cascades, particularly the doublesex genes, are highly conserved.

The neural basis for a persistent internal state in Drosophila females
eLife, 2020 Sustained changes in mood or action require persistent changes in neural activity, but it has been difficult to identify the neural circuit mechanisms that underlie persistent activity and contribute to long-lasting changes in behavior.

Genome-wide identification and comparative analysis of Dmrt genes in echinoderms
Scientific Reports, 2023 The Dmrt (Doublesex-mab3-related transcription factor) gene family is a class of crucial transcription factors characterized by one or several conserved DM (Doublesex/Mab-3) domains.

Courtship Anomalies Caused by doublesex Mutations in Drosophila melanogaster [PDF]
Genetics, 1996 Abstract The role played by the sex-deterrnining gene doublesex (dsx) and its influence on Drosophila courtship were examined. Against a background of subnormal male-like behavior that is reported to be an attribute of haplo-X flies homozygous for the original dsx mutation, and given that a sex-specific muscle is unaffected by genetic ...

The Doublesex-related Dmrta2 safeguards neural progenitor maintenance involving transcriptional regulation of Hes1 [PDF]
, 2017 The mechanisms that determine whether a neural progenitor cell (NPC) re-enters the cell cycle or exits and differentiates are pivotal for generating cells in correct numbers and diverse types, and hence dictate proper brain development. Combining gain-of-

Nature Communications, 2020 Polymorphic mimicry in Papilio swallowtail butterflies is thought to have had multiple independent origins. Here, the authors show that the gene doublesex controls mimicry across multiple species, but with distinct alleles that may have originated from ...

Loss of Cx43 in Murine Sertoli Cells Leads to Altered Prepubertal Sertoli Cell Maturation and Impairment of the Mitosis-Meiosis Switch. [PDF]
, 2020 Male factor infertility is a problem in today's society but many underlying causes are still unknown. The generation of a conditional Sertoli cell (SC)-specific connexin 43 (Cx43) knockout mouse line (SCCx43KO) has provided a translational model ...

The evolutionary genetics of highly divergent alleles of the mimicry locus in Papilio dardanus [PDF]
, 2014 Background: The phylogenetic history of genes underlying phenotypic diversity can offer insight into the evolutionary origin of adaptive traits. This is especially true where single genes have large phenotypic effects, for example in determining ...

Multiple Functions of the Dmrt Genes in the Development of the Central Nervous System
Frontiers in Neuroscience, 2021 The Dmrt genes encode the transcription factor containing the DM (doublesex and mab-3) domain, an intertwined zinc finger-like DNA binding module. While Dmrt genes are mainly involved in the sexual development of various species, recent studies have ...
