Marbling of cattle meat is dependent on the coordinated expression of multiple genes. Cattle dramatically increase their intramuscular fat content in the longissimus dorsi muscle between 12 and 27 months of age. We used the annealing control primer (ACP)-differential display RT-PCR method to identify differentially expressed genes (DEGs) that may participate in the development of intramuscular fat between early (12 months old) and late fattening stages (27 months old). Using 20 arbitrary ACP primers, we identified and sequenced 14 DEGs. BLAST searches revealed that expression of the MDH, PI4-K, ferritin, ICER, NID-2, WDNMI, telethonin, filamin, and desmin (DES) genes increased while that of GAPD, COP VII, ACTA1, CamK II, and nebulin decreased during the late fattening stage. The results of functional categorization using the Gene Ontology database for 14 known genes indicated that MDH, GAPD, and COP VII are involved in metabolic pathways such as glycolysis and the TCA cycle, whereas telethonin, filamin, nebulin, desmin, and ACTA1 contribute to the muscle contractile apparatus, and PI4-K, CamK II, and ICER have roles in signal transduction pathways regulated by growth factor or hormones. The final three genes, NID-2, WDNMI, and ferritin, are involved in iron transport and extracellular protein inhibition. The expression patterns were confirmed for seven genes (MDH, PI4-K, ferritin, ICER, nebulin, WDNMI, and telethonin) using real-time PCR. We found that the novel transcription repressor ICER gene was highly expressed in the late fattening stage and during bovine preadipocyte differentiation. This information may be helpful in selecting candidate genes that participate in intramuscular fat development in cattle.

The lipid extract of Perna canaliculus (Lyprinol) has known anti-inflammatory effects. However, the only information on mechanisms is regulation of cytokine secretion. Therefore, we conducted a proteomic study exploring the effects of Lyprinol on protein expression in splenocytes collected from AIA rats. Splenocytes from AIA rats fed with Lyprinol had increased protein expression of malate dehydrogenase (MDH). Lyprinol also decreased the expressions of 5 other proteins: protein-o-mannosyl- transferase 2 (PMT-2), Tdrd 7, telethonin, dynactin 2 and protein disulfide isomerase (PDI or glucose-regulated protein (GRP)). Besides MDH, PMT- 2, titin-cap protein and protein disulfide isomerase (PDI) are known to be related to metabolism. However, it is currently unknown if Lyprinol administration decreases metabolic glucose in the body and alleviates symptoms of inflammation and arthritis. Further experiments are required to correlate levels of citric acid intermediates and glucose to the severity of inflammation and pain in AIA rats fed Lyprinol.
