Comparative Molecular Characterization of Tumor Necrosis Factor alpha (TNFα) and Lipopolysaccharide Induced TNFα Factor (LITAF) genes from mullet Liza haematocheila
- Abstract
- Mullets are commercially important fishes throughout the world. Even though, production from mullet farming is increasing in recent years, mass mortality associated with pathogenic infections causes heavy economic loss. For the success of Korean mullet aquaculture, comprehensive understanding of mullet immune system is essential for better health management. TNF alpha and LITAF genes are important immune genes studied from wide range of aquatic organism for better understanding. This study showed that TNF alpha and LITAF genes are expressed ubiquitously in various tissues of mullet and upregulated with pathogenic challenge. LITAF genes were showed to be participating in apoptosis. All three mullet LITAF genes induce capase-3 activity. These LITAFs also induce TNF alpha expression. These study showed that TNF alpha and LITAF are critical immune genes could be targeted for better disease control in mullet.
