The molecular mechanism underlying muscle development in rabbits is not well-understood. In the current study, differentially-expressed genes were scanned using an expression profile chip in New Zealand white rabbits (introduced breed) and Fujian yellow rabbits (local breed), and some of the genes were tested using reverse transcription-polymerase chain r..

Orange-spotted grouper (Epinephelus coioides) is one of the most important marine fish and has a high market value. The insulin-like growth factor type 1 receptor (IGF1R) is a component of the insulin-like growth factor signaling system, and demonstrates important roles during growth. Based on information from livestock, we us.. Read More»

Growth hormone (GH) is a part of the somatotropic axis that controls metabolism, growth, development and aging in a wide range of animals. Mutations that reduce GH signaling have been associated with extended life spans and increased longevity in ways similar to what is observed in dietary restriction (DR) models. However, the..

In a 17-kb genomic fragment of Trypanosoma cruzi chromosome XX, we identified three tandemly linked genes coding for CX2CX4HX4C zinc finger proteins. We also showed that similar genes are present in T. brucei and Leishmania major, sharing three monophyletic groups among these trypanosomatids. In T. cruzi, TcZFP8 corresponds to.. Read More»

Polymerase chain reaction of a pentanucleotide microsatellite in the U1 snRNA gene complex generated a multiple band pattern due to the priming of paralogous sequences. Denaturation and slow renaturation of polymerase chain reaction products allow the formation of heteroduplex DNA that can be detected by its differential mobil.. Read More»

Spittlebugs are the leading cause of damage to tall grasses. Annual losses are estimated to reach 2.1 billion dollars in sugarcane crops and grazing land throughout the world. Correct identification of these species is difficult due to similarities in color, body size and male genitalia. Molecular markers have been useful in t.. Read More»

Giant panda cubs have a low survival rate during the newborn and early growth stages. However, the growth and developmental parameters of giant panda cubs during the early lactation stage (from birth to 6 months) are not well known. We examined the growth and development of giant panda cubs by the Chapman growth curve model and estimated the heritability .. Read More»

Age at the time of slaughter is a commonly used trait in animal breeding programs. Since studying this trait involves incomplete observations (censoring), analysis can be performed using survival models or modified linear models, for example, by sampling censored data from truncated normal distributions. For genomic selection,.. Read More»

The aims of this study were to investigate the effect of a mixture of bone marrow mesenchymal stem cells (BMSCs) and annulus fibrosus cells (AFCs) in repairing the degenerative discs of rabbits, and to provide an experimental basis for its clinical application. BMSCs from rabbits were cultured in vitro and mixed with AFCs. The animal model of degenerative.. Read More»

The karyotypes of water mites (Acari: Hydrachnellae: Hydrodromidae) are largely unknown. The present investigation is the first report of a study designed to characterize the chromosomes of water mites. The study was carried out with specimens of Hydrodroma despiciens collected from Eber Lake in Afyon, Turkey. Several differen.. Read More»
