The purpose of this study was to assess the topic use Sebastiania hispida extract and low-level gallium-arsenide laser irradiation (GaAs, 904 nm) reduce local myonecrosis edema Bothrops moojeni snake venom-injected gastrocnemius. Wistar rats receiving intramuscular venom injection (VBm) were compared with saline control (S) envenomed exposure plant (VExt) or (VL). phytochemistry thin-layer chro...

The objective of the present work was to identify and validate single nucleotide variations located in candidate genes to growth traits in tilapia (Oreochromis niloticus). Two transitions were identified in the promoter region of the growth hormone gene (GH); eight nucleotide changes were identified in introns and promoter region of the IGF-I gene; and a transition (T/C) was identified in the M...

BACKGROUND The expression of myogenic regulatory factors (MRFs) consisting of MyoD, Myf5, myogenin (MyoG) and MRF4 characterizes various phases of skeletal muscle development including myoblast proliferation, cell-cycle exit, cell fusion and the maturation of myotubes to form myofibers. Although it is well known that the function of MyoG cannot be compensated for other MRFs, the molecular mecha...

The study involved 110 hybrid grower-finisher pigs from Polish Large White × Polish Landrace sows sired by Pietrain breed boars and their crossbreds with the 990 line and Duroc. The aim of the study was to determine an association of the polymorphism of RYR1, myogenin (MYOG) genes and carcass meatiness level with carcass slaughter value and meat quality traits in hybrid pigs. Better meat qualit...

Skeletal and smooth muscle can mutually transdifferentiate, but little molecular insight exists as to how each muscle program may be subverted to the other. The myogenic basic helix-loop-helix transcription factors MyoD and myogenin (Myog) direct the development of skeletal muscle and are thought to be dominant over the program of smooth muscle cell (SMC) differentiation. Myocardin (Myocd) is a...

Source and Description of Probe. A 1,486-bp rat cDNA clone for myogenin (MYOG) was excised from the EcoRI site of the plasmid, pBluescrybe M13(Wright et al., 1989). Method of Detection. DNA was isolated from whole blood and digested with MspI. Fragments were then separated by agarose gel electrophoresis and transferred to charged nylon membranes. Hybridizations were at 65°C for 16 to 20 h (.5 M...

In animal breeding, selection based on growth is very often used, as this trait affects the profitability of production. Identification polymorphisms within genes affecting process seems to be important. Therefore, we decided analyse rabbit myogenin (<em>MyoG</em> gene) for potential polymorphic sites and their association with carcass traits in Termond White (TER), Belgian Giant Gr...

It is well known that myogenic regulatory factors encoded by the Myod1 family of genes have pivotal roles in myogenesis, with partially overlapping functions, as demonstrated for the mouse embryo. Myogenin-mutant mice, however, exhibit severe myogenic defects without compensation by other myogenic factors. MYOGENIN might be expected to have an analogous function in human myogenic cells. To veri...

To increase our current knowledge on the nutritional regulation of growth and gene expression pattern in fish skeletal muscle, effect dietary macronutrient composition was assessed digestibility, nutrient retention, performance, mRNA levels key genes involved functionality, development muscle gilthead sea bream (Sparus aurata). Long-term starvation decreased myogenic regulatory factors such as ...
