Cloning and Identification of Common Carp (<i>Cyprinus carpio</i>) <i>PI3KC3</i> and Its Expression in Response to CyHV-3 Infection
Phosphoinositide 3-kinases (PI3Ks) are a class of key regulatory factors in eukaryotes that can inhibit viral replication by influencing autophagy. Currently, cyprinid herpesvirus 3 (CyHV-3) poses a serious threat to common carp culture. However, PI3K has not yet been identified in common carp. In t...

| description | Phosphoinositide 3-kinases (PI3Ks) are a class of key regulatory factors in eukaryotes that can inhibit viral replication by influencing autophagy. Currently, cyprinid herpesvirus 3 (CyHV-3) poses a serious threat to common carp culture. However, PI3K has not yet been identified in common carp. In this study, full-length <i>PI3KC3</i> from common carp (<i>CcPI3KC3</i>), consisting of an open reading frame (ORF) of 2664 bp encoding a polypeptide of 887 amino acids, with a predicted molecular mass of 101.19 kDa and a theoretical isoelectric point (pI) of 5.97, was cloned. The amino acid and nucleotide sequences of CcPI3KC3 displayed high similarity to yellow catfish’s (<i>Tachysurus fulvidraco</i>) PI3KC3. The tissue expression profile revealed that the mRNA levels of <i>CcPI3KC3</i> in the liver, spleen, and head kidney were significantly greater than those in the brain, heart, intestines, gills, eyes, testes, and ovaries of common carp. We compared the expression patterns of <i>CcPI3KC3</i> between “Longke-11” mirror carp (CyHV-3-resistant carp) and German mirror carp (non-resistant to CyHV-3) at different times (0, 48, 96, 144 h, 192, 240, 288 h post-infection (hpi)) after CyHV-3 infection. The results revealed that <i>CcPI3KC3</i> mRNA expression significantly increased in the early infection stage. In the CyHV-3-resistant mirror carp variety, the relative expression of <i>CcPI3KC3</i> was significantly greater at 48, 96, and 144 hpi compared with the nonbreeding strain groups after infection (<i>p</i> < 0.001). These results indicate that the full-length <i>CcPI3KC3</i> sequence was successfully cloned from common carp for the first time, and it might play an important role in the immune system of common carp against CyHV-3 infection. This study provides a theoretical basis for the molecular mechanism of CyHV-3 resistance. |
