Establishment of Transgenesis in the Demosponge Suberites domuncula [PDF]

open access: yesGenetics, 2018
Abstract Sponges (Porifera) represent one of the most basally branching animal clades with key relevance for evolutionary studies, stem cell biology, and development. Despite a long history of sponges as experimental model systems, however, functional molecular studies are still very difficult to perform in these animals. Here, we report

The Skeletal Amino Acid Composition of the Marine Demosponge Aplysina cavernicola

open access: yesMarine Drugs, 2014
It has been discovered during the past few years that demosponges of the order Verongida such as Aplysina cavernicola exhibit chitin-based skeletons. Verongida sponges are well known to produce bioactive brominated tyrosine derivatives. We could recently

Determination of the Halogenated Skeleton Constituents of the Marine Demosponge Ianthella basta

open access: yesMarine Drugs, 2017
Demosponges of the order Verongida such as Ianthella basta exhibit skeletons containing spongin, a collagenous protein, and chitin. Moreover, Verongida sponges are well known to produce bioactive brominated tyrosine derivatives.

Reconstruction of family-level phylogenetic relationships within Demospongiae (Porifera) using nuclear encoded housekeeping genes. [PDF]

open access: yesPLoS ONE, 2013
Demosponges are challenging for phylogenetic systematics because of their plastic and relatively simple morphologies and many deep divergences between major clades.

Compositional and Quantitative Insights Into Bacterial and Archaeal Communities of South Pacific Deep-Sea Sponges (Demospongiae and Hexactinellida)

open access: yesFrontiers in Microbiology, 2020
In the present study, we profiled bacterial and archaeal communities from 13 phylogenetically diverse deep-sea sponge species (Demospongiae and Hexactinellida) from the South Pacific by 16S rRNA-gene amplicon sequencing.

Fate of Microplastic Captured in the Marine Demosponge Halichondria Panicea [PDF]

open access: yesMarine Pollution Bulletin, 2023
Microplastic particles are widespread pollutants in the sea and filter-feeding sponges have recently been suggested as useful monitoring organisms. However, the fate of microplastic particles in sponges is poorly understood, yet crucial for interpreting monitoring data.

Taxonomical and biogeographical notes on the sponges of the Strait of Magellan

open access: yesScientia Marina, 1999
The sponge material from the Straits of Magellan collected by the research vessels Cariboo in 1991 and Victor Hensen in 1994, and by a shallow water diving team, were studied.

Inhibitory Effect of Aqueous Extracts from Marine Sponges on the Activity and Expression of Gelatinases A (MMP-2) and B (MMP-9) in Rat Astrocyte Cultures. [PDF]

open access: yesPLoS ONE, 2015
The aim of this study was to evaluate whether water soluble compounds present in aqueous extracts from seven Mediterranean demosponges exert biological activity towards matrix metalloproteinases (MMPs), which represent important pathogenic factors of ...

miRNA Repertoires of Demosponges Stylissa carteri and Xestospongia testudinaria. [PDF]

open access: yesPLoS ONE, 2016
MicroRNAs (miRNAs) are small regulatory RNAs that are involved in many biological process in eukaryotes. They play a crucial role in modulating genetic expression of their targets, which makes them integral components of transcriptional regulatory ...
