Reproductive patterns of deep-sea invertebrates related to phylogeny and energy availability

open access: yes, 2000
Reproductive strategies and their interaction with the environment play a major role in the shaping of ecosystems. However, while our understanding of the diversity, biogeography and ecology of deep-sea invertebrates has increased considerably in the ...

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Reproduction and larval biology of North Atlantic asteroids related to the invasion of the deep sea

open access: yes, 2005
A very important objective of ecological research is to explain the evolution of life histories, more specifically how natural selection modifies reproduction and development in order to generate the patterns that are observed in nature.

Design and Control Strategy for a Solar -Powered Autonomous Underwater Vehicle with an Unconventional Shape

open access: yesPolish Maritime Research
Solar-powered autonomous underwater vehicles (SAUVs) can harness sustainable natural energy, meaning that they are capable of providing long-term mission support. This paper describes ongoing development work on the overall design of a SAUV.

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

open access: yesMolecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

open access: yesMolecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Biological activities of ethanolic extracts from deep-sea antarctic marine sponges

open access: yes, 2013
We report on the screening of ethanolic extracts from 33 deep-sea Antarctic marine sponges for different biological activities. We monitored hemolysis, inhibition of acetylcholinesterase, cytotoxicity towards normal and transformed cells and growth ...

Abiotic Siliceous Botryoids on Iron Oxyhydroxide Filaments From Hydrothermal Vents in the Southwest Indian Ocean

open access: yesGeochemistry, Geophysics, Geosystems
Fe‐oxidizing microorganisms in deep‐sea hydrothermal vent environments are often used as analogs for primordial life on Earth. In fact, Earth's oldest purported microfossils are preserved as hematite filaments in a jasper rock dated between 4,160 and 4 ...

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Community structure and spatial distribution of vent fauna in the hydrothermal fields of North Fiji Basin based on ROV visual survey

open access: yes, 2018
This study was conducted to investigate the community structure and distributional pattern of hydrothermal and adjacent deep-sea fauna at two hydrothermal vent fields (KF2 and KF3) on the central spreading axis in North Fiji Basin, from November to ...
