In this study, we collected 39 megalocytiviruses isolated from diseased fish in Korea from 2012 to 2018. Major capsid protein (MCP) gene, a part of vascular endothelial growth factor (VEGF) gene and histidine triad motif-like protein (HIT) genes of Megalocytivirus were targeted for PCR amplification...

참돔이리도바이러스병의 원인은? | 참돔이리도바이러스병 (red sea bream iridoviral diseases, RSIVD)의 원인 바이러스는 이리도바이러스과 (family Iridoviridae), 메갈로사이티바이러스속 (genus Megalocytivirus)에 속하며, 지름이 약 140-250 nm인 20면체 double strand DNA 바이러스이다 (Kurita and Nakajima, 2012; Chinchar et al., 2017). | |
메갈로사이티바이러스속의 유전형 분류는? | , 2017). Megalocytivirus의 유전형 분류는 major cap-sid protein (MCP) 및 adenosine triphosphatase(ATPase) 유전자 염기서열의 상관관계를 기반으로 하고 있다. Megalocytivirus의 유전형은 red sea bream iridovirus (RSIV)형, infectious spleen and kid-ney necrosis virus (ISKNV)형, 그리고 turbot reddish body iridovirus (TRBIV)형으로 총 3가지 유전형(genotype)으로 분류되며, RSIV형과 ISKNV형은 각 유전아형(subgroup 1형과 2형)으로 세분화하여 분류할 수 있다(Kurita and Nakajima, 2012). | |
VEGF란 무엇인가? | Vascular endothelial growth factor (VEGF)는 이리도바이러스과 (Iridoviridae)내에서 유일하게 Mega-locytivirus속 바이러스에만 존재하는 유전자로, Wang et al (2008)에 의하면 VEGF는 숙주 내에서 혈관 확산 유도와 침투성을 촉진하여 바이러스 감염 및 복제에 중요한 역할을 할 것이라 시사한 바 있다. Histidine triad motif로 되어 있는 HIT-like protein(HIT)은 거의 모든 생물체에서 발견되며 보존적인 단백질로, 기능적으로는 Hint (Histidine triad nu-cleotide-binding protein)와 Fhit (Fragile HIT protein)는 종양 형성을 억제하는 것으로 알려져 있으나 Megalocytivirus에서 HIT-like protein의 기능적인 역할은 아직 밝혀진 바 없다 (Brenner, 2002; Martin et al. |
