“…The type II mRNA with the 20-nt element was detected in intestine, pyloric caecum, kidney, spleen, and gill of healthy flounder (data not shown). This pattern of tissue distribution is similar to that of tilapia progranulin mRNA [27]. In contrast, the type I mRNA (lacking the 20-nt element) was not detected in any tissue of healthy flounder; however, it was found in gill, kidney, spleen and intestine of LPS-stimulated flounder.…”

“…Recently, the progranulin cDNAs were identified and characterized from gold fish [26] and tilapia [27]. The gold fish progranulin is a 159 amino acids polypeptide containing one-half of granulin domains, and tilapia has a 206-amino acid long with two domains.…”

“…Serumfree primary culture of salmon hepatocytes (Pierce et al, 2004) and tilapia (Schmid et al, 2000) continuously stimulated with GH showed a 6 h IGF-I transcription maximum as well. In Orechromis mossambiccus, administration of a single dose (500 ng/g body weight) of recombinant seabream GH by intraperitoneal injection resulted in a 2.5-fold increase of IGF-I mRNA in the liver at 3 h post-GH treatment (Chen et al, 2007).…”

The liver production of the insulin-like growth factor-I (IGF-I) is a key factor in the endocrine control of body growth by a growth hormone. As pejerrey Odontesthes bonariensis has been reported as a fish with low growth rates in captivity, basic research on this respect is needed in order to understand it. In this context, the pejerrey IGF-I cDNA was cloned and its hepatic expression was examined in fish after recombinant pejerrey growth hormone (pjGHr) administration. The full length of IGF-I transcript showed a high sequence similarity to other teleost sequences. The tissue distribution analysis by reverse transcriptase polymerase chain reaction in adult fish revealed that IGF-I expressed ubiquitously with the highest mRNA levels in the liver, posterior intestine and brain. No alternative IGF-I mRNA was found in the liver, as it was reported for other teleosts. IGF-I transcript was measured in the liver after pjGHr in vivo stimulation by means of quantitative real-time polymerase chain reaction assays. A dose-dependent response of IGF-I mRNA was observed after pjGHr administration, and reached a six-fold IGF-I maximum increase over control group when 2.5 microg pjGH/g-body weight (bw) was injected. Temporal analysis of hepatic IGF-I mRNA level showed that administration of a single dose of pjGHr into juvenile pejerrey resulted in a significant increase (P <0.02) 9 hours post-injection (hpi). These results add novel information on the nucleotide sequence of IGF-I in Atheriniformes and demonstrate that pjGHr could promote a dramatic response in liver, increasing the IGF-I mRNA level.

“…Hepatic igf1 mRNAs were up-regulated by administration of either homologous or heterologous GH in many teleost fish (Duguay et al, 1996;Tse et al, 2002;Vong et al, 2003;Peterson et al, 2005;Chen et al, 2007;Ponce et al, 2008). Although the GH-dependent induction of igf2 was less documented, a significant up-regulation in mRNA levels was also found in liver and pyloric ceca (Shamblott et al, 1995) of Oncorhynchus mykiss, in liver of Ictalurus punctatus (Peterson et al, 2005) and Anguilla japonica (Moriyama et al, 2008), and in liver, gills, intestine, muscle, and kidneys of Cyprinus carpio (Tse et al, 2002;Vong et al, 2003).…”
