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) reenters the cell cycle or exits and differentiates are pivotal for generating cells in the correct numbers and diverse types, and thus dictate proper brain development.

Sex- and tissue-specific functions of Drosophila doublesex transcription factor target genes.

, 2014
Primary sex-determination "switches" evolve rapidly, but Doublesex (DSX)-related transcription factors (DMRTs) act downstream of these switches to control sexual development in most animal species.

Asymmetric interactions between doublesex and tissue- and sex-specific target genes mediate sexual dimorphism in beetles

, 2017
Sexual dimorphisms fuel significant intraspecific variation and evolutionary diversification. Yet the developmental-genetic mechanisms underlying sex-specific development remain poorly understood.

Fruitless and Doublesex Coordinate to Generate Male-Specific Neurons that Can Initiate Courtship

, 2008
SummaryBiologists postulate that sexual dimorphism in the brain underlies gender differences in behavior, yet direct evidence for this has been sparse. We identified a male-specific, fruitless (fru)/doublesex (dsx)-coexpressing neuronal cluster, P1, in ...

Silencing the buzz: a new approach to population suppression of mosquitoes by feeding larvae double-stranded RNAs

Parasites & Vectors, 2015
Background Mosquito-borne diseases threaten over half the world’s human population, making the need for environmentally-safe mosquito population control tools critical.

Evolution of the sex-determination gene Doublesex within the termite lineage

Comparative Biochemistry and Physiology Part D: Genomics and Proteomics
ABSTRACT The molecular mechanism of sex determination has long been considered conserved in insects. However, recent studies of hemimetabolous insects have challenged this notion. One notable example is termites. In Reticulitermes speratus , a homolog of sex determination gene,

The Sex Determination Gene doublesex Regulates the A/P Organizer to Direct Sex-Specific Patterns of Growth in the Drosophila Genital Imaginal Disc

, 2001
Each Drosophila genital imaginal disc contains primordia for both male and female genitalia and analia. The sexually dimorphic development of this disc is governed by the sex-specific expression of doublesex (dsx).

Candidate target genes of the male-specific expressed Doublesex in the termite Reticulitermes speratus.

PLoS ONE
Eusocial insects such as termites, ants, bees, and wasps exhibit a reproductive division of labor. The developmental regulation of reproductive organ (ovaries and testes) is crucial for distinguishing between reproductive and sterile castes.
