Incorporation of uridine in cleavage stage eggs of the sea urchin Paracentrotus lividus.
Incorporation of uridine in cleavage stage eggs of the sea urchin Paracentrotus lividus was investigated. It was shown by ion exchange and thin layer chromatography that most of the uridine taken up during the 16-cell stage was converted into UTP with some incorporation into UDP and UMP. Conversion of uridine to these phosphorylated nucleosides occurred throughout early cleavage stages. A very ...
متن کاملFurther improvements in the sea urchin embryo cryopreservation protocol (Paracentrotus lividus)
Previous studies indicated the existence of some amount of variability in the embryonic development success of cryopreserved sea-urchin (Paracentrotus lividus) embryos. The present work studied the covariation of cryopreservation results fluctuations and reproductive parameters (condition index, CI and oocytes quality) during the reproductive season, in order to verify the hypothesis of the eff...
متن کاملGender differences in the immune system activities of sea urchin Paracentrotus lividus.
In the immune system of vertebrates, gender-specific differences in individual immune competence are well known. In general, females possess more powerful immune response than males. In invertebrates, the situation is much less clear. For this purpose we have chosen to study the immune response of the two sexes of the echinoderm Paracentrotus lividus in pre- and post-spawning phases. The coelom...
متن کاملNitric Oxide Mediates the Stress Response Induced by Diatom Aldehydes in the Sea Urchin Paracentrotus lividus
Diatoms are ubiquitous and abundant primary producers that have been traditionally considered as a beneficial food source for grazers and for the transfer of carbon through marine food webs. However, many diatom species produce polyunsaturated aldehydes that disrupt development in the offspring of grazers that feed on these unicellular algae. Here we provide evidence that production of the phys...
متن کاملNew inter-correlated genes targeted by diatom-derived polyunsaturated aldehydes in the sea urchin Paracentrotus lividus.
The marine environment is continually subjected to the action of stressors (including natural toxins), which represent a constant danger for benthic communities. In the present work using network analysis we identified ten genes on the basis of associated functions (FOXA, FoxG, GFI-1, nodal, JNK, OneCut/Hnf6, TAK1, tcf4, TCF7, VEGF) in the sea urchin Paracentrotus lividus, having key roles in d...
