Molecular mechanisms of sex determination in Lepidoptera: current status and perspectives

open access: yesInsect Science, EarlyView.
The genetic basis of sex determination in Lepidoptera was discovered in 2014 in the silkworm Bombyx mori. In this model species, the W chromosome‐derived small piRNA called Fem piRNA downregulates the expression of a Z‐linked gene, Masculinizer (Masc), which leads to the default female‐specific splicing of the doublesex gene (dsxF) and thus to female ...

Maltase 1 regulates DENV2 infection and life history in Aedes aegypti

open access: yesInsect Science, EarlyView.
Our study employed CRISPR/Cas9 to generate a MAL1 knockout strain of Aedes aegypti, demonstrating that the absence of MAL1 significantly suppresses DENV2 replication in the midgut and impairs viral transmission. The mutation also altered life‐history (hatching/pupation/emerging rates and sex‐specific survival), identifying MAL1 as a novel target for ...

The shibirets4 mutation causes temperature sensitive paralytic and lethal phenotypes in the Queensland fruit fly, Bactrocera tryoni

open access: yesInsect Science, EarlyView.
Abstract Bactrocera tryoni, the Queensland fruit fly, is among the most damaging insect pests to the Australian horticultural industry as larvae infest ripening fruits or vegetables prior to harvest. Genetic biocontrol using Sterile Insect Technique (SIT) programs have been used to successfully suppress populations, via mass release of factory‐reared ...

Neoclassical development of genetic sexing strains for insect pest and disease vector control

open access: yesInsect Science, EarlyView.
The sterile insect technique has been effectively used for decades, and an important component is the availability of sex separation systems, in particular genetic sexing strains. Classical approaches, such as irradiation‐induced chromosomal translocations, have yielded stable strains for species like the Mediterranean fruit fly.

Microhaplotype Methods Enable Relationship Inference in a Bottlenecked Mammalian Species

open access: yesAnimal Conservation, EarlyView.
Northern elephant seals (Mirounga angustirostris) are among the most genetically depauperate mammals in the world. A near‐total population bottleneck in the 19th century, coupled with the breeding system of extreme polygyny, has challenged efforts to estimate individual reproductive success with genetic methods.

Genotyping Contemporary Captive and Historical Wild Western Lowland Gorillas Indicates Captive Breeding Is Maintaining Genetic Diversity in a Critically Endangered Primate

open access: yesAnimal Conservation, EarlyView.
Captive populations of threatened species risk losing genetic diversity over time. We evaluated the genetic status of contemporary captive western lowland gorillas (Gorilla gorilla gorilla) at Howletts and Port Lympne and compared this with specimens from a historical wild population.

Early Epidemiologic and Immune Predictors of Atopic Dermatitis: Reduced Cord Blood Regulatory B10 Cells in the Munich Atopy Prediction Study (MAPS)

open access: yesAllergy, EarlyView.
In this prospective birth cohort from Munich, comprehensive clinical assessments and longitudinal lifestyle questionnaires were combined with cord blood immune profiling. Infants who later developed AD showed altered cord blood immune signatures, including reduced CD4+ T cells, increased B cells and markedly decreased Breg cells. Epidemiologic factors,

Somatic and germline genetic testing pathways in haematological malignancies: Best practice consensus guidelines from the 2025 national meeting organised by UK Cancer Genetics Group (UKCGG), CanGene‐CanVar and the NHS England Haematological Oncology Working Group

open access: yesBritish Journal of Haematology, EarlyView.
Summary Genomic technologies including next‐generation sequencing (NGS) and arrays for cytogenetic anomalies are now standard of care in England for the diagnostic evaluation of patients with suspected haematological malignancies. Challenges remain in the management of potential germline findings as a result of NGS panels and copy number variant ...
