Ancient Plumage Colour Genetics Reveal Goose Domestication and Hybridization

Animal Genetics, Volume 57, Issue 4, August 2026.
ABSTRACT In archaeological assemblages, differentiating the European domestic goose and its wild progenitor, the greylag goose (Anser anser), has been challenging due to their similar skeletal morphologies. A short region of mitochondrial DNA (mtDNA) analysed from ancient DNA (aDNA) has been shown to distinguish wild greylags from domestic geese, but ...

Preliminary Analysis of CpG, CHG and CHH Methylation in the Mitochondrial Control Region of Dogs With Malignant Mammary Gland Tumours

Animal Genetics, Volume 57, Issue 4, August 2026.
ABSTRACT Canine mammary tumours (CMTs) are one of the most frequently observed malignancies in female dogs. Many studies have investigated epigenetic changes in CMT at the nuclear level, yet the role of mtDNA methylation, particularly in the D‐loop region, remains largely unexplored.

miR155, triplicated in Down syndrome, regulates the development of neural stem cells and GABAergic interneurons in Alzheimer's disease mouse and human iPSC models

Alzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract INTRODUCTION Dysfunctional microRNAs and GABAergic interneurons are features of Alzheimer's disease (AD). The role of neuronal microRNA155 (miR155), elevated in both AD and Down syndrome (DS), remains unknown. METHODS We utilized in silico analyses of published databases, MIR155‐deleted and ‐overexpressing human induced pluripotent stem cell ...

Patient‐Derived Organoid‐Based CRISPR Screens in Cancer Research: Applications, Advances, and Challenges

Cancer Medicine, Volume 15, Issue 8, August 2026.
ABSTRACT Patient‐derived organoids (PDOs) have emerged as physiologically relevant cancer models that preserve key genetic, histological, and functional features of the tumors from which they are derived. In parallel, CRISPR‐based perturbation technologies have transformed functional genomics by enabling scalable interrogation of gene function.
