Lectins with Potential for Anti-Cancer Therapy

Molecules, 2015
This article reviews lectins of animal and plant origin that induce apoptosis and autophagy of cancer cells and hence possess the potential of being developed into anticancer drugs. Apoptosis-inducing lectins encompass galectins, C-type lectins, annexins,

Non-directional photoreceptors in the pluteus of Strongylocentrotus purpuratus

Frontiers in Ecology and Evolution, 2016
In comparison to complex visual systems, non-directional photoreception – the most primitive form of biological photodetection – has been poorly investigated, although it is essential to many biological processes such as circadian and seasonal rhythms ...

Sea urchin microbiomes vary with habitat and resource availability

Limnology and Oceanography Letters, 2021
Sea urchins are key grazers in coastal seas, where they can survive a variety of conditions and diets, enhancing their ecological impact on kelp forests and other ecosystems.

Associations between DNA methylation and gene regulation depend on chromatin accessibility during transgenerational plasticity

BMC Biology, 2023
Background Epigenetic processes are proposed to be a mechanism regulating gene expression during phenotypic plasticity. However, environmentally induced changes in DNA methylation exhibit little-to-no association with differential gene expression in ...

Network model predicts that CatSper is the main Ca2+ channel in the regulation of sea urchin sperm motility

Scientific Reports, 2017
Spermatozoa sea urchin swimming behaviour is regulated by small peptides from the egg outer envelope. Speract, such a peptide, after binding to its receptor in Strongylocentrotus purpuratus sperm flagella, triggers a signaling pathway that culminates ...

Characterization of the highly variable immune response gene family, He185/333, in the sea urchin, Heliocidaris erythrogramma. [PDF]

PLoS ONE, 2014
This study characterizes the highly variable He185/333 genes, transcripts and proteins in coelomocytes of the sea urchin, Heliocidaris erythrogramma. Originally discovered in the purple sea urchin, Strongylocentrotus purpuratus, the products of this gene

Oxygen availability and body mass modulate ectotherm responses to ocean warming

Nature Communications, 2023
In an ocean that is rapidly warming and losing oxygen, accurate forecasting of species’ responses must consider how this environmental change affects fundamental aspects of their physiology.

A method for identifying alternative or cryptic donor splice sites within gene and mRNA sequences. Comparisons among sequences from vertebrates, echinoderms and other groups

BMC Genomics, 2009
Background As the amount of genome sequencing data grows, so does the problem of computational gene identification, and in particular, the splicing signals that flank exon borders.

Trophic Transfer of Macroalgal Fatty Acids in Two Urchin Species: Digestion, Egestion, and Tissue Building

Frontiers in Ecology and Evolution, 2018
Sea urchins are ecosystem engineers of nearshore benthic communities because of their influence on the abundance and distribution of macroalgal species.
