In honeybees, queens synthesize the "queen pheromone," whereas workers synthesize fatty acid components of "royal jelly" in their mandibular glands (MGs). To identify candidate proteins involved in the caste-selective MG function, we performed a proteomic analysis and identified three proteins that were expressed selectively in queen MGs (aldehyde dehydrogenase 1 [ALDH1], medium-chain acyl-CoA dehydrogenase [MCAD], and electron transfer flavoprotein alpha [ETFalpha)]), and a protein that was expressed selectively in worker MGs (fatty acid synthase [FAS)]). The quantitative reversed transcription-polymerase chain reaction demonstrated that the level of aldh1 transcription in MGs was significantly higher, whereas that of fas transcription was lower in queens than in workers. Among the eight genes encoding proteins similar to ALDH1 that are registered in the honeybee genome database, aldh6, aldh7, and aldh1 were expressed at significantly higher levels in queen MGs than in worker MGs. In situ hybridization showed that in the queen head, aldh1 was expressed in MG cells, whereas aldh6 and aldh7 were expressed in fat cells attached to the MGs. These results suggest caste- and cell type-selective aldehyde/fatty acid metabolism in honeybee MGs.

Body-weight differences in animals may be ascribed to genetic and environmental factors. Here we utilized two divergent porcine genotypes, the highly muscled, leaner PietrianxYorkshire pigs and less muscled, fatter DurocxYorkshire growing pigs (75-110 kg), to examine the role of genetic background on expression of genes associated with anabolic (Fatty acid synthase, FAS; glucose transporter 4, GLUT-4; stearoyl CoA desaturase, SCD; Sterol regulatory binding protein-1, SREBP-1; leptin) and catabolic lipid metabolism (Carnitine palmitoyltransferase-1B, CPT-1B; acyl-CoA dehydrogenase, ACDH) in adipose tissue (AT), liver (L) and skeletal muscle (SKM). Pietrain pigs had lower mRNA abundance for FAS, SREBP-1, SCD and leptin in AT and L, but higher mRNA abundance for L ACDH and SKM ACDH and CPT-1B than Durocs. Duroc pigs exhibited higher expression of FAS, SREBP-1, SCD, leptin in AT and FAS in L and lower expression of ACDH and CPT-1B in L SKM. GLUT-4 expression did not differ in SKM between the two genotypes. Feeding of a beta adrenergic agonist (Paylean) for 52 days lowered expression of lipid anabolic and enhanced lipid catabolic genes expressions similarly in both genotypes. Overall, the lipid metabolism genes differential expression patterns documented here showed that in Pietrain pigs mRNA abundances of synthesis genes were lower and of catabolic genes were higher than in Duroc pigs.
