Mitochondria and Neuromast Tagging With Fluorescent Gallium‐Triapine Analogues: In Cellulo MP FLIM and Zebrafish Live Imaging

open access: yesAdvanced Science, EarlyView.
Fluorescent BODIPY‐conjugated thiosemicarbazone ligands and their Ga(III), In(III), and Fe(III) complexes, inspired by Triapine, are developed as theranostic agents. Multiphoton FLIM and confocal microscopy in cancer cells and zebrafish reveal real‐time uptake, mitochondrial localisation, and whilst spectroscopic assays indicated preserved complex ...

The molecular evolution of sex and reproduction related genes, hybrid male sterility and spectiation in the drosophila melanogaster complex [PDF]

open access: yes, 2003
Haldane's rule, which states that the heterogametic sex is preferentially afflicted if one of hybrid sexes is sterile or inviable, is a general pattern in all animals that possess sex chromosomes.

Disruption of Treg Homeostasis in Rheumatoid Arthritis via Ferroptosis‐Mediated ETC Collapse and TXK‐STAT3/PLCγ1 Activation

open access: yesAdvanced Science, EarlyView.
In rheumatoid arthritis, synovial Tregs accumulate but are functionally impaired due to iron overload‐induced ferroptosis. This triggers mitochondrial dysfunction and TXK tyrosine kinase‐mediated signaling, leading to Treg destabilization and inflammation.

Redox‐Dependent Chaperoning of GBF1 Condensates Regulates Seed Germination in Arabidopsis

open access: yesAdvanced Science, EarlyView.
In dormant seeds (low ROS), GBF1 forms liquid condensates to repress the germination gene CathB3, and the chaperone GIP1 maintains condensate liquidity and repressive activity. Upon imbibition (high ROS), ROS oxidize GIP1 during germination, impairing its chaperone function.

Identification of Hybrid Sterility Genes in Drosophila

open access: yes, 2014
Reproductive isolation is central to the maintenance of species boundaries. The evolution of post-zygotic genome incompatibilities is a widespread mechanism caused by the disruption of allelic interactions in hybrids; it ensures that matings between ...

Comparative Oligo‐FISH Mapping Illuminates Chromosomal Evolution Among Rutaceae Species Diverged Over 50 Million Years

open access: yesAdvanced Science, EarlyView.
Oligonucleotide‐based fluorescence in situ hybridization probes were developed in the model citrus species Citrus maxima. These probes were applied to comparative karyotyping across 14 species in the Rutaceae family. This analysis revealed chromosomal evolution in lineages that diverged from Citrus nearly 52 million years ago.

Genetic basis of hybrid male sterility among three closely related species of Drosophila

open access: yes, 2005
455-461The genetic basis of hybrid male sterility among three closely related species, Drosophila bipectillala, D. parabipectinata and D. malerkotliana has been investigated by using backcross analysis methods.
