Insulin-like growth factor (IGF) expression plays a critical role in the endocrine regulation of proliferation, differentiation, and growth in shellfish as well as in fish. The Pacific oyster, Crassostrea gigas, is a significant aquaculture species that comprises a large percentage of the Korean shellfish industry; moreover, its growth is economically important in aquaculture. However, when measuring the growth rate in shellfish, the soft tissue weight is difficult to determine because of the shell weight. In the present study, we describe an indirect method of measuring the growth rate using multiplex polymerase chain reaction (PCR) and analyzing levels of molluscan insulin-related peptide (MIP), the acid labile subunit of the IGF-binding protein complex (IGFBP ALS), and insulin-related peptide receptor (CIR) in Pacific oysters...

Naked DNA has been shown to bind naturally to the sperm, a method called sperm-mediated gene transfer (SMGT). Based on these observations, we examined the efficiency of exogenous DNA binding to sperm using liposomes. In this experiment, we analyzed methods to select frozen-thawed bovine sperm, and evaluated the binding of exogenous DNA to those sperm. To determine the optimal selection method, we used Computer-Assisted Sperm Analysis (CASA). Percoll or Swim-Up were used to select sperm, followed by incubation up to 3 h with the liposome-DNA complexes...

Mitochondria play a central role in the energy homeostasis in eukaryotic cells by generating ATP via oxidative metabolism of nutrients. Excess lipid accumulation and impairments in mitochondrial function have been considered as putative mechanisms for the pathogenesis of skeletal muscle insulin resistance. Accumulation of lipids in tissues occurs due to either excessive fatty acid uptake, decreased fatty acid utilization or both. Consequently, elevated levels cytosolic lipid metabolites, triglycerides, diacylglycerol and ceramides have been demonstrated to adversely affect glucose homeostasis...

A synthetic cDNA-AmyA gene was cloned and successfully expressed in Pichia pastoris as a His-tagged enzyme under the methanol inducible AOX1 promoter. High level of extracellular amylase production of 72 U/mL was obtained after a 72 h induction by methanol. As expected, the recombinant strain produced only the AmyA isoform since the host is a protease deficient strain. Besides, the purified r-AmyA showed a molecular mass of 54 kDa, the same pH optimum equal to 5.6 but a higher thermoactivity of 60 °C against 50 °C for the native enzyme...

Ascites syndrome (AS) is a metabolic disorder that mainly occurs at later ages of meat-type chickens. Despite many research, there is no consensus about the origin of this syndrome. Our main purpose were to investigate the syndrome using both phenotypic and RNA-Seq data to elucidate the most causative factors predisposing the birds to AS. Phenotypic data analysis showed that AS indicator traits (AITs) were moderate to high heritable. Inexistence of consistent direct genetic correlation between AITs and growth related traits, indicated that neither faster growth rate nor heavier body weight is the most causative factor affecting the susceptibility of broilers to AS...

The hormone insulin plays a central role in the metabolism of carbohydrates, lipids, and proteins. In relation to protein metabolism, insulin stimulates amino acid uptake and activates protein synthesis in responsive cells by modulation of signal transduction pathways, such as associated to Akt/PkB, mTOR, S6Ks, 4E-BP1, and several translation initiation/elongation factors. In this context, there is no information on direct cellular treatment with insulin and effects on eukaryotic translation initiation factor 5A (eIF5A) regulation...

Genome-wide association studies normally focus on low penetrance and moderate to high-frequency single nucleotide polymorphisms (SNPs), which lead to genetic susceptibility to breast cancer. In this regard, the T allele of rs3803662 has been associated with breast cancer risk and with lower expression level of TOX3. We aimed to assess the risk of breast cancer associated with this polymorphism in an Iranian population. Using Tetra Primer ARMS PCR, rs3803662 was analyzed in a total of 943 individuals (430 cases and 513 healthy controls form North East of Iran)...
