Nature Communications, 2017 Genes and circuits involved in sleep and sexual arousal have been extensively studied in Drosophila. Here the authors identify the sex determination genes fruitless and doublesex, and a sex-specific P1-DN1 neuronal feedback that governs the interaction ...

The gene
BMC Evolutionary Biology, 2010 Background In the tephritids Ceratitis, Bactrocera and Anastrepha, the gene transformer provides the memory device for sex determination via its auto-regulation; only in females is functional Tra protein produced.

Animal Conservation, EarlyView.We used pattern recognition software to correct misidentifications in a 15‐year photographic database of the last, vulnerable West African giraffe population in Niger. After revealing substantial methodological errors that had inflated population estimates by nearly 19%, we corrected individual encounter histories and applied capture‐mark‐recapture ...

DMRTA2 Regulates Radial Glial Maintenance and Tumorigenicity of Paediatric High‐Grade Glioma
Journal of Cellular and Molecular Medicine, Volume 30, Issue 6, March 2026.ABSTRACT DMRTA2 is a member of the evolutionarily conserved transcription factor family involved in various developmental processes including neurogenesis. However, the roles of DMRTA2 in human development and disease are not fully characterised. Single cell RNA‐seq data analysis showed that DMRTA2 is robustly expressed in neural progenitors, in ...

Molecular evolution of Drosophila Sex-lethal and related sex determining genes
BMC Evolutionary Biology, 2012 Background Sex determining mechanisms are evolutionarily labile and related species often use different primary signals and gene regulatory networks. This is well illustrated by the sex determining cascade of Drosophila fruitflies, which have recruited ...

American Journal of Medical Genetics Part A, Volume 200, Issue 2, Page 496-501, February 2026.ABSTRACT Spondylocostal dysostosis (SCDO) is a rare genetic disorder characterized by abnormal development of the axial skeleton, resulting in malformations of the vertebrae and ribs that often impair lung development and lead to significant respiratory morbidity.

PLoS Genetics, 2012 The formation or suppression of particular structures is a major change occurring in development and evolution. One example of such change is the absence of the seventh abdominal segment (A7) in Drosophila males.

Phylogenetic analysis and embryonic expression of panarthropod Dmrt genes
Frontiers in Zoology, 2019 Background One set of the developmentally important Doublesex and Male-abnormal-3 Related Transcription factors (Dmrt) is subject of intense research, because of their role in sex-determination and sexual differentiation.

Functional Ecology, Volume 40, Issue 1, Page 51-69, January 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Phenotypic plasticity allows many animals to quickly respond to seasonal changes in their environment. Seasonal changes to physiological systems, such as sensory systems, may explain other more obvious changes in behaviour, often working synergistically with changes in ...

Sex determination in Drosophila melanogaster and Musca domestica converges at the level of the terminal regulator doublesex [PDF]
, 2018 Sex-determining cascades are supposed to have evolved in a retrograde manner from bottom to top. Wilkins' 1995 hypothesis finds support from our comparative studies in Drosophila melanogaster and Musca domestica, two dipteran species that separated some ...
