Recombinant truncated tilapia growth hormone enhances growth and innate immunity in tilapia fry (Oreochromis sp.)

Novel function of recombinant pituitary adenylate cyclase-activating polypeptide as stimulator of innate immunity in African catfish (Clarias gariepinus) fry

“…In fish, lectins with various carbohydrate specificities have been isolated from the serum, eggs and larvae of several fish species [53][54][55][56]. Recently, it was demonstrated that an intact and a truncated variant of tilapia GH increased lectin titers in tilapia fry after 45 days of hormone administration by bath immersion [57]. In the present study PRP stimulated lectin synthesis in C. gariepinus fry at 21 days of treatment.…”

Thermal treatment enhances the stability and biological activity of a truncated tilapia somatotropin contained in Pichia pastoris culture supernatant

“…We demonstrated that this truncated tiGH enhanced growth and some innate immune functions (lysozyme and lectins) in fish larvae (Acosta et al, 2008) and in culture leukocytes (superoxide anion production and proliferation) (Acosta et al, 2010). These results suggested to us the development of a new biotechnology product for larval growth and innate immune system improvement.…”

“…In a previous study, we unexpectedly found that tilapia somatotropin secreted by transformed cells of the yeast Pichia pastoris was truncated (Acosta et al, 2008). We demonstrated that this truncated tiGH enhanced growth and some innate immune functions (lysozyme and lectins) in fish larvae (Acosta et al, 2008) and in culture leukocytes (superoxide anion production and proliferation) (Acosta et al, 2010).…”

Respons Pertumbuhan Dan Keragaan Darah Dari Tiga Strain Ikan Nila Terhadap Pemberian Hormon Pertumbuhan Rekombinan Ikan Kerapu Kertang

“…Streptococcosis dapat menyebabkan kerugian besar bagi pembudidaya ikan intensif, dengan tingkat kematian ikan > 50% dalam waktu lebih dari satu minggu (Inglis et al, 1993;Yanong & Francis-Floyd, 2006). Studi tentang hubungan antara pemberian rGH dengan peningkatan kapasitas sistem imun telah dilakukan oleh Acosta et al (2008) yang menunjukkan adanya peningkatan respons imunitas bawaan pada larva ikan nila yang direndam dengan recombinant truncated tGH. Pengujian hormon pertumbuhan rekombinan ikan kerapu kertang (rElGH) dalam pakan untuk memacu pertumbuhan ikan dan peningkatan sistem kekebalan tubuh atau imunitas ikan sudah dilakukan pada udang vaname Litopenaeus vannamei (Subaidah, 2012) dan kerapu bebek Cromileptes altivelis (Antoro, 2014).…”
