Glycogenin-1; Glycolytic potential; Muscle-fiber type; Myosin heavy chains; Pig

This study analyzed the effect of muscle-fiber type composition on glycogenin-1 (GYG) gene expression and its impact on pH. The longissimus dorsi (LD) muscle contains more type IIB fibers (75.10%) than does the psoas major (PM) muscle (41.58%), while the PM has more type I (3.65 vs 0.94%), type IIA (34.15 vs 10.63%), and type IIX (20.62 vs 13.33%) fibers. ... more

Drip loss; Longissimus dorsi; Meat color; Muscle fiber type; Real-time quantitative polymerase chain reaction

In this study, we examined changes in meat quality and content of muscle types during porcine growth. The influence of the longissimus dorsi muscle fiber composition on meat quality and the correlation between 2 fiber-typing methods (histochemistry and real-time quantitative polymerase chain reaction) were examined. Type IIx and type IIb fibers accounted for most of the total number of fibers ... more

Melatonin; Mitochondria; Myocardial ischemia/reperfusion injury

We aimed to evaluate the effect of melatonin on myo­cardial cell oncosis in the myocardial ischemia/reperfusion injury rat, and the role of the mitochondrial permeability transition pore (MPTP) therein. Sprague Dawley rats (N = 60) were randomly divided into five groups of 12 rats each: control, ischemia/reperfusion (I/R), melatonin treatment (MT), melatonin treatment + atractyloside (MT ... more

Hypertension; Mitochondria; Mitochondrial tRNA mutations; Pathogenic mutations

Mutations in mitochondrial DNA have been found to be associated with hypertension. Of these, mitochondrial transfer RNA (mt-tRNA) is a hot spot for these pathogenic mutations. It is generally believed that these mutations may result in the failure of mt-tRNA metabolism, thereby worsening mitochondrial dysfunction and resulting in hypertension. mt-tRNA is known for its high frequency of ... more

Molecular methods are powerful tools in characterizing and determining relationships between plants. The aim of this study was to study genetic divergence between 103 accessions of Mexican Opuntia. To accomplish this, polymerase chain reaction (PCR)-restriction fragment length polymorphism analysis of three chloroplast intergenic spacers (atpB-rbcL, trnL ... more

Animals; Electron Transport Complex IV; Energy metabolism; Mitochondria; Ursidae

The giant panda, Ailuropoda melanoleuca (Ursidae), has a unique bamboo-based diet; however, this low-energy intake has been sufficient to maintain the metabolic processes of this species since the fourth ice age. As mitochondria are the main sites for energy metabolism in animals, the protein-coding genes involved in mitochondrial respiratory chains, particularly cytochrome c oxidase subunit ... more

The mitochondrial calcium uptake 1 (MICU1) is a regulatory subunit of the mitochondrial calcium uniporter that plays an important role in calcium sensing. It contains two EF-hand domains that are well conserved across diverse species from protozoa to plants and metazoans. The loss of MICU1 function in mammals is attributed to several neurological disorders that involve movement dysfunction. ... more

Growth arrest and DNA-damage-inducible protein 45 alpha gene; meat quality; Pig; Single nucleotide polymorphism

This study was conducted to evaluate the porcine gene GADD45A (growth arrest and DNA-damage-inducible protein 45 alpha) as a positional candidate controlling quantitative trait loci (QTL) for meat quality traits on chromosome 6 (SSC6). Four exons of the porcine GADD45A gene were defined from cDNA and BAC clone sequences. A total of 4 single nucleotide ... more

ADSL; Intramuscular fat; Meat color; meat quality; Pig

In this study, meat quality traits were compared between Chinese lard- and European lean-type pigs. The association between expression of four genes (ADSL, GARS-AIRS-GART, DGAT1, and DECR1) and meat quality traits was also investigated. Meat quality traits were found to differ significantly between pig breeds. Meat color parameter values (a* and b*) and ... more

Coat color; meat quality; Native pig breeds; PCR-RFLP; Vertebra number

Mutations in melanocortin 1 receptor (MC1R) gene and v-kit Hardy-Zuckerman 4 feline sarcoma viral oncogene homolog (KIT) gene have been shown to affect coat color patterns in pigs. Additional functional marker genes, such as insulin like growth factor-2 (IGF2) and orphan nuclear receptor, germ cell nuclear factor (NR6A1), have been described for ... more
