The study shows that cAMP responsiveness, not LHR abundance, determines ovulatory fate in cloudy catshark follicles, challenging the LHR-threshold model.

The paper studies estrogen receptor activation in elephant shark, finding three active ER genes and one unresponsive gene, with similar estrogen responses to humans.

This study investigates the microbial environment inside the egg capsules of cloudy catsharks during oviposition, finding low bacterial density and unique microbial composition that may protect embryos from infection.

This study establishes in vitro and in vivo gene introduction methods in cloudy catshark embryos and adult testis using electroporation and baculovirus, enabling genetic manipulation in cartilaginous fishes.
