Differences in the Structural Components Influence the Pumping Capacity of Marine Sponges

Autor: Azraj S. Dahihande, Narsinh L. Thakur

Publikováno v: Frontiers in Marine Science, Vol 8 (2021)

Marine sponges are important sessile, benthic filter feeders with a body plan designed to pump water efficiently. The sponge body plan generally consists of mineral spicules, gelatinous mesohyl, and the pores and canals of the aquiferous system. Thes

Tissue homeostasis in sponges: quantitative analysis of cell proliferation and apoptosis

Autor: Ksenia V. Skorentseva, Nikolai P. Melnikov, Alina A. Saidova, Andrey Lavrov, Fyodor V. Bolshakov, Veronika S. Frolova, Alexander V. Ereskovsky

BackgroundTissues of multicellular animals are maintained due to a tight balance between cell proliferation and programmed cell death. Phylum Porifera is an early branching group of metazoans essential to understanding the key mechanisms of tissue ho

Cancer recurrence and severe side effects of currently being used chemotherapeutic agents reduce their clinical efficacy. Thus, there is a constant need to develop alternative anticancer drugs. Sustainable supply is an important challenge facing mari

Localized production of defence chemicals by intracellular symbionts of Haliclona sponges

Autor: Ma. Diarey B. Tianero, Mohamed S. Donia, Jared N. Balaich

Publikováno v: Nature microbiology

Marine sponges often house small-molecule-producing symbionts extracellularly in their mesohyl, providing the host with a means of chemical defence against predation and microbial infection. Here, we report an intriguing case of chemically mediated s

Publikováno v: In vitro cellulardevelopmental biology. Animal. 57(5)

Sponges are among the most primitive multicellular organisms and well-known as a major source of marine natural products. Cultivation of sponge cells has long been an attractive topic due to the prominent evolutionary and cytological significance of

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, 2020, 334 (1), pp.37-58. ⟨10.1002/jez.b.22919⟩

Origin and early evolution of regeneration mechanisms remain among the most pressing questions in animal regeneration biology. Porifera have exceptional regenerative capacities and, as early Metazoan lineage, are a promising model for studying evolut

Wnt signaling and polarity in freshwater sponges

Autor: Pamela J. Windsor Reid, Alexandra McClymont, Dora Posfai, Sally P. Leys, Eugueni Matveev, April Hill

Publikováno v: BMC Evolutionary Biology, Vol 18, Iss 1, Pp 1-14 (2018)
BMC Evolutionary Biology

Background The Wnt signaling pathway is uniquely metazoan and used in many processes during development, including the formation of polarity and body axes. In sponges, one of the earliest diverging animal groups, Wnt pathway genes have diverse expres

Phagocytosis of microbial symbionts balances the carbon and nitrogen budget for the deep-water boreal sponge Geodia barretti

Autor: Tina Kutti, Amanda S. Kahn, Raymond Bannister, James K. H. Fang, Sally P. Leys

Publikováno v: Limnology and Oceanography. 63:187-202

Geodia barretti is a massive nearly spherical sponge that forms dense assemblages on the continental shelf of the North Atlantic and the Norwegian Sea. We studied the metabolism of individual sponges collected using a remotely operated vehicle and ma

Spicule and flagellated chamber formation in a growth zone ofAphrocallistes vastus(Porifera, Hexactinellida)

Autor: Sally P. Leys, Amanda S. Kahn

Publikováno v: Invertebrate Biology. 136:22-30

Three species of glass sponges (Class Hexactinellida) form massive deep-water reefs by growing on the skeletons of past generations, with new growth largely vertical and away from sediment that buries the lower portions. Growth is therefore essential
