Recombinant tilapia Neuropeptide Y promotes growth and antioxidant defenses in African catfish (Clarias gariepinus) fry

A novel GH secretagogue, A233, exhibits enhanced growth activity and innate immune system stimulation in teleosts fish

“…; McKenzie et al 2000). In addition, administration by immersion baths of neuropeptide Y recombinant African catfish larvae (C. gariepinus) increased the concentration of reduced glutathione and SOD activity, without producing any effect on the activity of catalase (Carpio et al 2007). Also, in larvae of tilapia treated with recombinant tilapia, GH was increased in the activity of SOD and catalase (Acosta et al 2011).…”

“…Administration of tilapia recombinant neuropeptide Y (Oreochromis sp.) to larvae of African catfish (C. gariepinus) also produced an increase in animal weight (Carpio et al 2007). In addition, treatment with PACAP and PACAP-related peptide from C. gariepinus larvae of African catfish (C. gariepinus), tilapia (O. niloticus), and common carp (Cyprinus carpio) increased body weight and length in three fish species .…”

Recombinant novel pituitary adenylate cyclase-activating polypeptide from African catfish (Clarias gariepinus) authenticates its biological function as a growth-promoting factor in low vertebrates

“…For example, in goldfish, gonadotropin-releasing hormone appeared quickly in the plasma following its application to gills (Sherwood & Harvey 1986). In our laboratory, we have employed the immersion bath technique to study the effects of nutritional supplements and growth factors on growth control and the immune system in fish (Martinez et al 2006, Carpio et al 2007.…”

Expression of Neuropeptide Y of GIFT Tilapia (Oreochromis sp.) in Yeast Pichia Pastoris and Its Stimulatory Effects on Food Intake and Growth

“…The similar fasted growth results were found in other studies. NPY injection significantly induced energy consumption and body weight of goldfish (Narnaware and Peter, 2001a;Narnaware and Peter, 2001b) and tilapia (Carpio et al, 2006;Kiris GA, 2007); 18 and 30 days after immersion baths with recombinant NPY expressed by Escherichia coli three times a week, body weight and body length of catfish were significantly higher than the control (Carpio Y, 2007); Both injection and oral administration with human NPY significantly promoted the growth and body weight of tilapia (Kiris GA, 2007). The effect of NPY on food intake and growth seems dosage and species specific and too high or too low dosage could not elevate food intake in fish and shrimp (Kiris GA, 2007;Narnaware and Peter, 2001b), The growth and food intake of tilapia Oreochromis niloticus were both significantly higher at dosage of 0.25μg/g feed compared to the control, but lower dosage of 0.125 μg/g feed only stimulated food intake (Kiris GA, 2007); Although the group of red tilapia injected with 0.1mg/gbw of recombinant NPY showed a weight increase of 26% when compared to the control group, it is still not statistically significant (Carpio et al, 2006).…”

“…of tilapia NPY significantly promoted the growth and food intake of tilapia by injection (Carpio et al, 2006). Immersion bath with the same prokaryotic expression of NPY three times a week significantly increased the body weight and body length of catfish (Carpio Y, 2007). NPY either administered by i.p.…”
