Abstract
In addition to its central role in cellular metabolism, adenosine 5'-triphosphate (ATP) is an important extracellular signalling molecule involved in various physiological processes. In reproduction, extracellular ATP participates in both autocrine and paracrine paths regulating gametogenesis, gamete maturation and fertilisation. This review focusses on how extracellular ATP modulates sperm physiology with emphasis on the mammalian acrosome reaction. The presence of extracellular ATP in the reproductive tract is primarily determined by the ion channels and transporters that influence its movement within the cells comprising the tract. The main targets of extracellular ATP in spermatozoa are its own transporters, particularly species-specific sperm purinergic receptors. We also discuss notable phenotypes from knock-out mouse models and human Mendelian inheritance related to ATP release mechanisms, along with immunological, proteomic, and functional observations regarding sperm purinergic receptors and their involvement in sperm signalling.

Abstract
Studies of colonization of new habitats that appear from rapidly changing environments are interesting and highly relevant to our understanding of divergence and speciation. Here, we analyse phenotypic and genetic variation involved in the successful establishment of a marine fish (sand goby, Pomatoschistus minutus) over a steep salinity drop from 35 PSU in the North Sea (NE Atlantic) to two PSU in the inner parts of the post-glacial Baltic Sea. We first show that populations are adapted to local salinity in a key reproductive trait, the proportion of motile sperm. Thereafter, we show that genome variation at 22,190 single nucleotide polymorphisms (SNPs) shows strong differentiation among populations along the gradient. Sequences containing outlier SNPs and transcriptome sequences, mapped to a draft genome, reveal associations with genes with relevant functions for adaptation in this environment but without overall evidence of functional enrichment. The many contigs involved suggest polygenic differentiation. We trace the origin of this differentiation using demographic modelling and find the most likely scenario is that at least part of the genetic differentiation is older than the Baltic Sea and is a result of isolation of two lineages prior to the current contact over the North Sea-Baltic Sea transition zone.

Abstract
To gain fertilizing capacity, mammalian sperm should reside in the female tract for a period of time. The physiological changes that render the sperm able to fertilize are known as capacitation. Capacitation is associated with an increase in intracellular pH, an increase in intracellular calcium, and phosphorylation of different proteins. This process is also accompanied by the hyperpolarization of the sperm plasma membrane potential (Em). In the present work, we used flow cytometry to analyze changes in sperm Em during capacitation in individual cells. Our results indicate that a subpopulation of hyperpolarized mouse sperm can be clearly distinguished by sperm flow cytometry analysis. Using sperm bearing green fluorescent protein in their acrosomes, we found that this hyperpolarized subpopulation is composed of sperm with intact acrosomes. In addition, we show that the capacitation-associated hyperpolarization is blocked by high extracellular K(+), by PKA inhibitors, and by SLO3 inhibitors in CD1 mouse sperm, and undetectable in Slo3 knockout mouse sperm. On the other hand, in sperm incubated in conditions that do not support capacitation, sperm membrane hyperpolarization can be induced by amiloride, high extracellular NaHCO3, and cAMP agonists. Altogether, our observations are consistent with a model in which sperm Em hyperpolarization is downstream of a cAMP-dependent pathway and is mediated by the activation of SLO3 K(+) channels.

Abstract
Both genes and the environment are determinants in the susceptibility to allergies and may alter the severity of the disease. We explored whether an increase in the levels of the lipid mediator S1P in vivo, a condition found during allergic asthma, could affect the sensitivity or the response of MCs to IgE/Ag and the onset of allergic disease. We found that increasing S1P levels by genetic deletion of S1P lyase, the enzyme catabolizing S1P, led to elevated activity of circulating tryptase. Accordingly, MCs of S1P lyase-deficient mice were mostly degranulated in the tissues and showed enhanced calcium levels, degranulation, and cytokine production in response to IgE/Ag in vitro. Th 1-skewed mice (C57BL/6) had lower levels of S1P in circulation and histamine responses than did Th 2-skewed (129/Sv) mice. However, when S1P levels were increased by pharmacologic inhibition of S1P lyase, the C57BL/6 mice showed increased histamine release into the circulation and anaphylactic responses similar to those in the 129/Sv mice. Culturing of MCs in the presence of S1P enhanced their degranulation responses, and when the S1P-treated MCs were used to reconstitute MC-deficient (Kit(W-sh)) mice, they caused enhanced anaphylaxis. Gene expression arrays in S1P lyase-deficient MCs and MCs treated with S1P continuously revealed increased expression of numerous genes, including the adhesion molecule CNTN4,which contributed to the enhanced responses. Our findings argue that dysregulation in the metabolism of S1P is a contributing factor in modulating MC responsiveness and the allergic response.

Abstract
The activation of sea urchin eggs at fertilization provides an ideal system for studying the molecular events involved in cellular activation. Rho GTPases, which are key signaling enzymes in eukaryotes, are involved in sustaining the activation of sea urchin eggs; however, their downstream effectors have not yet been characterized. In somatic cells, RhoA regulates a serine/threonine kinase known as Rho-kinase (ROCK). The activity of ROCK in early sea urchin development has been inferred, but not tested directly. A ROCK gene was identified in the sea urchin (Strongylocentrotus purpuratus) genome and the sequence of its cDNA determined. The sea urchin ROCK (SpROCK) sequence predicts a protein of 158 kDa with >72% and 45% identities with different protein orthologues of the kinase catalytic domain and the complete protein sequence, respectively. SpROCK mRNA levels are high in unfertilized eggs and decrease to 35% after 15 min postfertilization and remain low up to the 4 cell stage. Antibodies to the human ROCK-I kinase domain revealed SpROCK to be concentrated in the cortex of eggs and early embryos. Co-immunoprecipitation assays indicate that RhoA and SpROCK are physically associated. This association is destroyed by treatment with the C3 exoenzyme and with the ROCK antagonist H-1152. H-1152 also inhibited DNA synthesis in embryos. We conclude that the Rho-dependent signaling pathway, via SpROCK, is essential for early embryonic development.

Abstract
Sulfated fucans and galactans are strongly anionic polysaccharides found in marine organisms. Their structures vary among species, but their major features are conserved among phyla. Sulfated fucans are found in marine brown algae and echinoderms, whereas sulfated galactans occur in red and green algae, marine angiosperms, tunicates (ascidians), and sea urchins. Polysaccharides with 3-linked, beta-galactose units are highly conserved in some taxonomic groups of marine organisms and show a strong tendency toward 4-sulfation in algae and marine angiosperms, and 2-sulfation in invertebrates. Marine algae mainly express sulfated polysaccharides with complex, heterogeneous structures, whereas marine invertebrates synthesize sulfated fucans and sulfated galactans with regular repetitive structures. These polysaccharides are structural components of the extracellular matrix. Sulfated fucans and galactans are involved in sea urchin fertilization acting as species-specific inducers of the sperm acrosome reaction. Because of this function the structural evolution of sulfated fucans could be a component in the speciation process. The algal and invertebrate polysaccharides are also potent anticoagulant agents of mammalian blood and represent a potential source of compounds for antithrombotic therapies.
