Comparative genomics reveals evolutionary loss of epiplakin in cetaceans

Scientific Reports, 2022
The adaptation of vertebrates to different environments was associated with changes in the molecular composition and regulation of epithelia. Whales and dolphins, together forming the clade cetaceans, have lost multiple epithelial keratins during or ...

Distribution of Cetaceans in the Canary Islands (Northeast Atlantic Ocean): Implications for the Natura 2000 Network and Future Conservation Measures

Frontiers in Marine Science, 2021
The waters of the Canary Islands are considered a hotspot for marine biodiversity, especially regarding cetacean species. Based on this fact, this study pays attention to the spatial distribution pattern of cetacean species and the conservation role of ...

Accelerated evolution and diversifying selection drove the adaptation of cetacean bone microstructure

BMC Evolutionary Biology, 2019
Background The transition from land to sea by the ancestor of cetaceans approximately 50 million years ago was an incredible evolutionary event that led to a series of morphological, physiological, and behavioral adaptations. During this transition, bone

Decompressive Pathology in Cetaceans Based on an Experimental Pathological Model

Frontiers in Veterinary Science, 2021
Decompression sickness (DCS) is a widely known clinical syndrome in human medicine, mainly in divers, related to the formation of intravascular and extravascular gas bubbles.

The molecular evolution of genes previously associated with large sizes reveals possible pathways to cetacean gigantism

Scientific Reports, 2023
Cetaceans are a group of aquatic mammals with the largest body sizes among living animals, including giant representatives such as blue and fin whales.

Modelling the spatial distribution of cetaceans in New Zealand waters

Diversity and Distributions: A journal of biological invasions and biodiversity, 2020
Cetaceans are inherently difficult to study due to their elusive, pelagic and often highly migratory nature. New Zealand waters are home to 50% of the world's cetacean species, but their spatial distributions are poorly known.

Patterns of enrichment and acceleration in evolutionary rates of promoters suggest a role of regulatory regions in cetacean gigantism

BMC Ecology and Evolution, 2023
Background Cetaceans (whales, porpoises, and dolphins) are a lineage of aquatic mammals from which some species became giants. Only recently, gigantism has been investigated from the molecular point of view.

Cetacean Intracytoplasmic Eosinophilic Globules: A Cytomorphological, Histological, Histochemical, Immunohistochemical, and Proteomic Characterization

Animals, 2023
The nature, etiopathogenesis, and clinicopathologic relevance of the prevalent intracytoplasmic eosinophilic globules (IEGs) within hepatocytes of cetaceans are unknown.

Genomic and anatomical comparisons of skin support independent adaptation to life in water by cetaceans and hippos

bioRxiv, 2020
The macroevolutionary transition from terra firma to obligatory inhabitance of the marine hydrosphere has occurred twice in the history of Mammalia: Cetacea and Sirenia.

Positive selection and gene duplications in tumour suppressor genes reveal clues about how cetaceans resist cancer

bioRxiv, 2020
Cetaceans are the longest-living species of mammals and the largest in the history of the planet. They have developed mechanisms against diseases such cancer, although the underlying molecular bases of these remain unknown.
