De novo transcriptome analysis of the Indian squid Uroteuthis duvaucelii (Orbigny, 1848) from the Indian Ocean.
Sci Data

ICAR-Central Marine Fisheries Research Institute, Ernakulam North P.O., Kochi, 682018, Kerala, India.
Article Synopsis
- - Cephalopods, like squids, have thrived in oceans for millions of years and are seen as advanced due to their large brains and complex sensory systems, exemplifying convergent evolution.
- - This study focuses on creating a reference transcriptome for the Indian squid Uroteuthis duvaucelii to enhance understanding of cephalopod evolution and expand existing knowledge databases.
- - Researchers generated 72 million short reads from various tissues (brain, eye, gill, heart, and gonads), identifying over 26,000 protein-coding sequences, and found that this squid shares numerous genes and pathways with higher vertebrates.
Effect of trematode infection on cardiac activity of marine gastropod Littorina littorea in situ and under laboratory conditions.

Department of Multidisciplinary Scientific Research, Karelian Research Centre of the RAS, 186005 Petrozavodsk, Russia.
Physiological mechanisms underlying relationships between the trematode parthenitae and their molluscan hosts are poorly understood. In this study, we estimated the cardiac function of gastropods Littorina littorea L. infected with Himasthla elongata and Cryptocotyle lingua under laboratory conditions and in situ.

Article Synopsis
- * Exposed embryos showed significant delays in hatching, malformations, reduced locomotion, and decreased feeding activity, indicating that TBT affects physiological functions even at low concentrations.
- * This research also reveals for the first time the presence of tin in various tissues of TBT-treated hatchlings, emphasizing the need for further investigations into the cellular and molecular mechanisms of TBT's harmful effects.
Functional characterization and related evolutionary implications of invertebrate gonadotropin-releasing hormone/corazonin in a well-established model species.

In vertebrates, gonadotropin-releasing hormone (GnRH) peptide is the central mediator of reproduction. Homologous peptides have previously also been identified in molluscan species. However, emerging evidence suggests that these molecules might serve diverse regulatory functions and proposes to consider them as corazonin (CRZ).

The presence of oral contraceptives (basically applying estrogens and/or progestogens) poses a challenge to animals living in aquatic ecosystems and reflects a rapidly growing concern worldwide. However, there is still a lack in knowledge about the behavioural effects induced by progestogens on the non-target species including molluscs. In the present study, environmental progestogen concentrations were summarised.
