Reproductive Physiology and Molecular Mechanisms Underlying Testicular Development and Spermatogenesis in Echinoderms: A Marine Invertebrate Deuterostomes

Molecular Reproduction and Development, Journal Year: 2025, Volume and Issue: 92(1)

Published: Jan. 1, 2025

ABSTRACT Echinoderms exhibit a wide range of reproductive strategies as adaptations to variable environments. The processes gonadal development, germ cell differentiation, and spermatogenesis in echinoderms are crucial physiological that warrant further in‐depth exploration. This review systematically summarizes research from early basic sciences recent studies on male development spermatogenesis, encompassing morphology, histology, physiology, biology, developmental evolutionary biology. We introduce the structural cellular similarities differences among model or non‐model organisms five classes provide insights for future comparative between higher vertebrates lower organisms. regulatory systems involved echinoderm described various aspects including nutritional supply, environmental factors, neurological influences, endocrinological hormonal influences. article aims elucidate echinoderms—organisms at unique nodes—providing valuable materials studying adaptive evolution Additionally, comprehensive summary characterized genes gene markers associated with testes is provided useful information systematic subpopulations. Future can focus molecular changes chromatin remodeling during intercellular communication mediated by receptor‐ligand interactions, our understanding biological networks spermatogenesis.

Yolk proteins of the schistosomiasis vector snail Biomphalaria glabrata revealed by multi-omics analysis

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Jan. 20, 2024

Abstract Vitellogenesis is the most important process in animal reproduction, which yolk proteins play a vital role. Among multiple protein precursors, vitellogenin (Vtg) well-known major (MYP) oviparous animals. However, nature of MYP freshwater gastropod snail Biomphalaria glabrata remains elusive. In current study, we applied bioinformatics, tissue-specific transcriptomics, ovotestis-targeted proteomics, and phylogenetics to investigate large lipid transfer (LLTP) superfamily ferritin-like family B. . Four members LLTP (BgVtg1, BgVtg2, BgApo1, BgApo2), one ferritin (Bg ferritin), four soma ferritins 1, 2, 3, 4) were identified genome. The proteomic analysis demonstrated that, among putative proteins, BgVtg1 was appearing highest amount ovotestis, followed by Bg ferritin. RNAseq profile showed that leading synthesis sites are ovotestis (presumably follicle cells) digestive gland, respectively. Phylogenetic indicated well clustered with Vtgs other vertebrates invertebrates. We conclude (BgVtg1), not precursor schistosomiasis vector

Seasonal tissue-specific gene expression in wild crown-of-thorns starfish reveals reproductive and stress-related transcriptional systems

PLoS Biology, Journal Year: 2024, Volume and Issue: 22(5), P. e3002620 - e3002620

Published: May 14, 2024

Animals are influenced by the season, yet we know little about changes that occur in most species throughout year. This is particularly true tropical marine animals experience relatively small annual temperature and daylight changes. Like many coral reef inhabitants, crown-of-thorns starfish (COTS), well known as a notorious consumer of corals destroyer reefs, reproduces exclusively summer. By comparing gene expression 7 somatic tissues procured from wild COTS sampled on Great Barrier Reef, identified more than 2,000 protein-coding genes change significantly between summer winter. appear to mediate conspecific communication, including both signalling factors released into surrounding sea water cell surface receptors, up-regulated external secretory sensory summer, often sex-specific manner. Sexually dimorphic appears be underpinned sex- season-specific transcription (TFs) regulatory programs. There over 100 TFs seasonally expressed, 87% which Six nuclear receptors all suggesting systemic seasonal hormonally controlled, vertebrates. Unexpectedly, there suite stress-related chaperone proteins TFs, HIFa, ATF3, C/EBP, CREB, NF-κB, uniquely widely co-expressed gravid females.
