Sexual dimorphism of sleep regulated by juvenile hormone signaling in Drosophila. [PDF]

PLoS Genetics, 2018
Sexually dimorphic phenotypes are a universal phenomenon in animals. In the model animal fruit fly Drosophila, males and females exhibit long- and short-sleep phenotypes, respectively. However, the mechanism is still a mystery.

Chromodomain Helicase DNA–Binding Proteins and Spermatogenesis: Current Advances

Andrology, EarlyView.
ABSTRACT Background Male infertility is a prevalent clinical condition, with approximately one‐third of cases classified as idiopathic, frequently stemming from impaired spermatogenesis because of dysregulated gene expression. Chromodomain helicase DNA‐binding (CHD) proteins are central chromatin remodelers that orchestrate this epigenetic regulation ...

Fertility incentives in Canada: Period and cohort perspectives

Canadian Journal of Economics/Revue canadienne d'économique, EarlyView.
Abstract We study the fertility effects of the 1997 Quebec Family Policy using two complementary approaches: (i) a period‐based repeated cross‐sectional analysis that examines the impact on period fertility (i.e., fertility rates in a given calendar year, such as births per 1,000 women age 15 to 49), and (ii) a cohort‐based panel analysis that examines

Identification of sex-specific transcripts of theAnopheles gambiae doublesexgene [PDF]

Journal of Experimental Biology, 2005
SUMMARYThe understanding of the molecular mechanisms of sex differentiation in the mosquito Anopheles gambiae could identify important candidate genes for inducing selective male sterility in transgenic lines or for sex-controlled expression of lethal genes.

Developmental link between sex and nutrition; doublesex regulates sex-specific mandible growth via juvenile hormone signaling in stag beetles. [PDF]

PLoS Genetics, 2014
Sexual dimorphisms in trait expression are widespread among animals and are especially pronounced in ornaments and weapons of sexual selection, which can attain exaggerated sizes.

How did the Canada Child Benefit affect household bargaining?

Canadian Journal of Economics/Revue canadienne d'économique, EarlyView.
Abstract Child benefits in Canada are sizable, targeted to children and paid to custodial mothers, and so might be expected to affect household resource allocations and spousal bargaining. The introduction of the Canada Child Benefit in July 2016 more than doubled the amount of child benefits received by households with children. We estimate the effect

Prospects of multipurpose biomonitoring for fisheries assessment based on environmental nucleic acids

Journal of Fish Biology, EarlyView.
Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

Sexually dimorphic traits in the silkworm, Bombyx mori, are regulated by doublesex [PDF]

Insect Biochemistry and Molecular Biology, 2017
The DM domain genes, doublesex (dsx) in insects, or their structural homologs, male abnormal 3 (mab-3) in nematodes and Dmrt1 (doublesex and mab-3-related transcription factor 1) in mammals, are downstream regulators of the sex determination pathway that control sexually dimorphic development.

Forebrain Lineage Factor DMRTA2 Is Not Required for Maintenance of H3G34‐Mutant Paediatric High‐Grade Gliomas

Journal of Cellular and Molecular Medicine, Volume 30, Issue 14, July 2026.
ABSTRACT Developmental transcriptional programs are increasingly recognized as key drivers of paediatric gliomagenesis. Here, we unexpectedly find that the forebrain‐specific doublesex‐ and mab‐3‐related transcription factor a2 (DMRTA2), despite being highly expressed in H3G34‐mutant diffuse hemispheric glioma (DHG‐H3G34) and implicated in tumour ...

Sex Determination in Sponges

Molecular Reproduction and Development, Volume 93, Issue 6, June 2026.
ABSTRACT Sex determination in Porifera remains one of the least understood aspects of early metazoan biology despite the group's key phylogenetic position. Sponges display exceptional diversity in sexual systems—ranging from stable gonochorism to sequential hermaphroditism and sex reversal—yet lack morphological dimorphism and any discrete gonadal ...
