“…Moreover, our detection of the significantly increased LPL activity and mRNA expression in the liver of tilapia was consistent with the research of Liang et al (2002) on Pagrosomus major. Liang et al (2002) Fish Physiol Biochem (2011 declared that the effect of starvation on liver LPL mRNA expression was correlated with the lipid content of feed fed before starvation, that was when fed a standard commercial diet, liver LPL mRNA expression level in the 48-h-starved Pagrosomus major was strikingly higher (by 40 times) than those overeating ones, whereas when fed a high-fat diet, the 48-h starvation imposed no significant influence upon liver LPL gene expression level. In our research, the diet (before starvation began) was a standard commercial diet, the changing of LPL mRNA expression in liver is consistent with these results.…”

“…Nowadays, most researches concerning the nutritional regulation of LPL and HSL are carried out in higher terrestrial animals (Sztalryd and Kraemer 1994;Sugden et al 1993;Spurlock et al 2001;Sato and Akiba 2002). Few investigations have been conducted to probe the activities and gene expression of LPL and HSL during starvation in fish (Liang et al 2002;Albalat et al 2006).…”

A 4-week study was conducted to determine the effect of starvation on activities and mRNA expression of lipoprotein lipase (LPL) and hormone-sensitive lipase (HSL) in hybrid tilapia (Oreochromis niloticus x O. areus). The tissue samples were sampled once a week. Results showed that body weight (BW) and hepatosomatic index (HSI) were decreased significantly (P < 0.05) during starvation. The percentages of crude fat and crude protein in the whole body and the fat content in muscle decreased significantly (P < 0.05), while the rate of moisture and crude ash increased significantly (P < 0.05). The response of LPL, HSL activities and mRNA expression in tissues was tissue dependent. The activities of LPL and HSL in muscle at day 7 were elevated by 2.5 times (P < 0.05) and 11.8 times (P < 0.05) of the value at day 0, respectively, and both then decreased to pre-starvation levels at day 14 and finally stabilized at a certain level afterward. LPL and HSL mRNA abundance in muscle remained relatively stable between 0 and 14 day; then, a significant increase was seen after 14 days. In the liver, LPL activity maintained a significantly increasing trend during starvation, while HSL activity rose dramatically at day 7 of starvation by 2.35 times (P < 0.05) and finally stabilized at a certain level. The mRNA abundance of liver LPL increased significantly during the whole process of starvation (P < 0.05), whereas the mRNA abundance of liver HSL decreased significantly at day 7 of starvation, elevating significantly afterward (P < 0.05).

A study was carried out to determine the effects of fish meal (FM) replacement by plant protein (PP) on growth, body composition and lipid metabolism of blackspot seabream fed different protein/lipid levels. Four experimental diets were formulated to contain two protein (P) and lipid (L) levels (60P/6L or 50P/10L), varying in their protein source (100% FM or 50% FM: 50% PP). Dietary inclusion of PP did not affect growth of fish fed 60P/6L, although fish fed 50P/10L exhibited lower final body weight and daily growth index. Fish fed 60P/6L presented the highest protein and the lowest lipid content. FM replacement by PP has decreased muscle n‐3 whereas the n‐6 fatty acids increased. Glucose‐6‐phosphate dehydrogenase and fatty acid synthetase (FAS) were depressed in fish fed 50P/10L. FAS was significantly increased with 60P/6L PP which was positively correlated with lipid retention data. Those results suggest the conversion of other nutrient than lipid (protein and/or carbohydrates) into corporal fat. Hepatic lipoprotein lipase activity was lowest in fish fed PP diets. Plasma glucose peaked 1–2 h postfeeding, in all groups and was generally higher with 60P/6L FM. This work shown that besides dietary P/L level, protein source has a strong effect on species lipogenesis and lipid retention. Hence, the 50P/10L FM diet was the most cost‐effective for blackspot seabream juveniles.

“…Dietary lipid levels promote hepatic LPL mRNA expression in dark barbel catfish [18] and in red sea bream [19], but decrease hepatic FAS mRNA expression in GIFT tilapia. Our study further demonstrated that high dietary lipid did not only induce and regulate the expression of hepatopancreas LPL, but also suppressed and regulate the expression of hepatopancreas FAS.…”
