LncRNA pol-lnc78 as a ceRNA regulates antibacterial responses via suppression of pol-miR-n199-3p-mediated SARM down-regulation in .

Long non-coding RNAs (lncRNAs) function as key modulators in mammalian immunity, particularly due to their involvement in lncRNA-mediated competitive endogenous RNA (ceRNA) crosstalk. Despite their recognized significance in mammals, research on lncRNAs in lower vertebrates remains limited. In the present study, we characterized the first immune-related lncRNA (pol-lnc78) in the teleost Japanese flounder ( ).

HcToll3 was involved in anti-Vibrio defense in freshwater pearl mussel, Hyriopsis cumingii.

Toll-like receptors (TLRs) play an important role in the activation of innate immune response but their functions in bivalves remain largely unknown. In this study, we identified a TLR from the freshwater pearl mussel Hyriopsis cumingii (HcToll3) and investigated its functions in immunity. The full-length cDNA of HcToll3 is 3852 bp and includes an open reading frame (ORF) of 3228 bp that encodes a polypeptide of 1075 amino acids.

Characterization of two novel ADP ribosylation factors from giant freshwater prawn Macrobrachium rosenbergii and their responses to WSSV challenge.

ADP-ribosylation factors (Arfs) are small GTP-binding proteins that have an essential function in intracellular trafficking and organelle structure. To date, little information is available on the Arfs in the economically important giant freshwater prawn Macrobrachium rosenbergii and their relationship to viral infection. Here we identified two Arf genes from M.

Cloning and characterization of two different L-type lectin genes from the Chinese mitten crab Eriocheir sinensis.

L-type lectins contain a leguminous lectin domain and bind to high-mannose type oligosaccharides. In the secretory pathway, L-type lectins play crucial functions in the trafficking, sorting, and targeting of maturing glycoproteins. This study identified two novel L-type lectins, designated as EsERGIC-53 and EsVIP36, from the Chinese mitten crab Eriocheir sinensis.

The first Toll receptor from the triangle-shell pearl mussel Hyriopsis cumingii.

Toll receptor was first discovered in Drosophila and has an important function in the innate immunity of invertebrates. In this study, the Toll receptor HcToll1 from Hyriopsis cumingii with a full length of 3810 bp consisting of a 3687 bp ORF that encodes a total of 1228 amino acids protein was selected for further study. The HcToll1 protein consisted of a signal peptide, 17 LRR domains, 2 LRRCT domains, 1 LRRNT domain, 1 TM domain, and 1 TIR domain.

Molecular characterization of marbled eel (Anguilla marmorata) gonadotropin subunits and their mRNA expression profiles during artificially induced gonadal development.

Three cDNA sequences encoding the gonadotropin subunits, common glycoprotein alpha subunit (GTHalpha), FSHbeta and LHbeta subunits were isolated from marbled eel. The cDNA of GTHalpha encodes 116 amino acids with a signal peptide of 24 amino acids and a mature peptide of 92 amino acids. The FSHbeta subunit consists of 127 amino acids with a 22 amino acid signal peptide and a 105 amino acid mature peptide, while the LHbeta subunit consists of 140 amino acids with a 24 amino acid signal peptide and a 116 amino acid mature peptide.
