MYC drives autophagy to adapt to stress in Penaeus vannamei
Fish & Shellfish Immunology, 2022MYC proto-oncogene (MYC), a first oncogenic nuclear transcription factor isolated from the human genome, belongs to the helix loop helix/leucine zipper protein family (bHLHzip). MYC plays an important part in the process of various physiological and biochemical of vertebrate, such as cell growth, proliferation, cycle, and autophagy.

Penaeus vannamei isotrypsins: purification and characterization
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2004Three isotrypsins from digestive gland of Penaeus vannamei were purified and characterized by molecular, biochemical and kinetic parameters. Purified isotrypsins A, B, and C are glycoproteins with molecular masses between 30.2 and 32.9 kDa, and, therefore similar to other trypsins.

Biochemical characterization of recombinant Penaeus vannamei trypsinogen
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2019Trypsinogens are the inactive precursors of trypsins (EC 3.4.21.4), which are digestive serine proteases. Despite knowing the properties of trypsins from Pacific white shrimp, Penaeus vannamei, the biochemical properties of shrimp trypsinogens including activation mechanisms and kinetics are unknown, due to difficulties isolating them from natural ...

Vitamin E requirement of Penaeus vannamei
Aquaculture, 1993Abstract An 8-week feeding trial was conducted to determine the dietary vitamin E requirement of the white-legged shrimp, Penaeus vannamei , using semi-purified diets. Shrimp exhibited significantly increased weight gain when fed increasing levels of vitamin E from 0 to 100 mg/kg diet, whereas no significant difference in growth was observed for ...

Transmission of Necrotizing Hepatopancreatitis in Penaeus vannamei
Journal of Invertebrate Pathology, 1993Abstract Necrotizing hepatopancreatitis (NHP) has been an important disease of shrimp mariculture in Texas since it was first recognized in 1985. This disease has resulted in mass mortalities of Penaeus vannamei in commercial growout ponds. Though the cause has remained an enigma, results of a recent morphologic study suggested that the etiology was ...

In this paper, the decay law of lactic acid bacteria in Penaeus vannamei culture habitat was studied, and its effects on ammonia nitrogen, nitrite and algae in the culture water of Penaeus vannamei were investigated. The high-efficiency application of acid bacteria in Penaeus vannamei culture was provided.

Experiments on the growth of Penaeus vannamei Boone
Journal of Experimental Marine Biology and Ecology, 1980Growth rates of Penaeus vannamei Boone were estimated from field and laboratory experiments using both marked and unmarked shrimp. Field results with unmarked shrimp indicated growth rates of between 0.05 mm increase in carapace length per day (mm c.l./day) and 0.17 mm c.l./day, although rates of up to 0.31 mm c.l./day were also recorded.

cDNA cloning of the lysozyme of the white shrimp Penaeus vannamei
Fish & Shellfish Immunology, 2003Lysozyme, an antibacterial protein, has been implicated in innate immunity in invertebrates, but its activity in shrimp remained to be determined. We cloned the white shrimp lysozyme cDNA using a PCR strategy and detected its activity in haemocytes using a lytic-zone assay against Micrococcus luteus.
