UnknownAnalysis of the molecular mechanism of inosine monophosphate deposition in Jingyuan chicken muscles using a proteomic approach.
Inosine monophosphate (IMP) is an indicator of meat taste, and the molecular mechanism underlying IMP deposition in muscle tissues is important to developing superior poultry breeds. The aim of this study was to identify the key proteins regulating IMP deposition in different muscle groups of 180-da...

UnknownTranscriptomic and metabolomic-based revelation of the effect of fresh corn extract on meat quality of Jingyuan chicken.
To investigate the effect of fresh corn extract (FCE) on chicken meat quality, 135-day-old Jingyuan chicken hens were fed diets containing different doses of FCE (CON, 0.3% FCE, 0.6% FCE and 0.9% FCE) until 180 day-old in this study. Meat performance measurements showed that the 0.6% FCE group of Ji...

UnknownCorrelation Analysis between AK1 mRNA Expression and Inosine Monophosphate Deposition in Jingyuan Chickens.
In this study, we examined correlations between the deposition of inosine monophosphate (IMP) and mRNA expression of the adenylate kinase 1 (AK1) gene in Jingyuan chicken. The IMP content was determined by high-performance liquid chromatography. Transcriptome sequencing was used to screen the differ...

UnknownIntegrating proteomics and metabolomics to elucidate the molecular network regulating of inosine monophosphate-specific deposition in Jingyuan chicken.
Inosine monophosphate (IMP) plays a significant role in meat taste, yet the molecular mechanisms controlling IMP deposition in muscle tissues still require elucidation. The present study systematically and comprehensively explores the molecular network governing IMP deposition in different regions o...

UnknownWGCNA-based integration of transcriptomics and metabolomics reveals key meat quality regulators during development in Jingyuan chickens.
Jingyuan chickens are known for their unique meat flavor, but the molecular mechanisms underlying the dynamic changes in meat quality at different developmental stages remain unclear. In this study, we systematically measured the meat quality indicators of 42-, 126- and 180-day-old Jingyuan chickens...

UnknownMetabolomics and Transcriptomics Reveal Age-Dependent Development of Meat Quality Traits in Jingyuan Chicken.
In this study, we investigated the dynamic changes in muscle lipid content (MLC) deposition in the breast muscle of Jingyuan chickens at different stages (42-, 126-, and 180- days old) using metabolomics. The pH45min, a*, and L* were significantly increased in the breast muscle of 126-day...

UnknownIdentification of key differentially methylated genes regulating muscle development in chickens: insights from Jingyuan breed.
Skeletal muscle development is a complex, regulated physiological process that involves myoblast proliferation and differentiation and the fusion of myotubes. In this study, phenotypic differences in the breast and leg muscles of 180-day-old Jingyuan chickens were investigated. Differentially methyl...

UnknownTranscriptome analysis reveals the role of long noncoding RNAs in specific deposition of inosine monphosphate in Jingyuan chickens.
Inosine monphosphate (IMP) is one of the important indicators for evaluating meat flavor, and long noncoding RNAs (lncRNAs) play an important role in its transcription and post-transcriptional regulation. Currently, there is little information about how lncRNA regulates the specific deposition of IM...

UnknownFunctional identification of PGM1 in the regulating development and depositing of inosine monophosphate specific for myoblasts.

Background

Inosine monophosphate (IMP) is naturally present in poultry muscle and plays a key role in improving meat flavour. However, IMP deposition is regulated by numerous genes and complex molecular networks. In order to excavate key candidate genes that may regulate IMP synthesis, we pe...
