Biomarkers of meat fat content - a review

HAL (Le Centre pour la Communication Scientifique Directe) (2010)

Jean-François J.-F. Hocquette Florence Gondret Élisabeth Baéza Françoise Médale Catherine C. Jurie

Intramuscular fat (IMF) content plays a key role in various quality traits of meat. Finding relevant biomarkers of IMF is thus a challenging area. IMF content varies between muscle types and also between species, breeds and individuals depending on gender, age, growth paths and feeding. Variability in IMF content is mainly linked to the number and size of intramuscular adipocytes, but also to muscle growth rate. Not only do muscle cells and adipocytes interplay during growth, but early events that influence adipogenesis inside the muscle are also likely to be involved in inter-individual differences in IMF content. Increasing muscularity will also dilute the final fat content of muscle. At the metabolic level, IMF content results from the balance between uptake, synthesis and degradation of triacylglycerols, which involve many metabolic pathways in both adipocytes and myofibres.

Myogenesis Is Delayed in Bovine Fetal Clones

Cellular Reprogramming (2010)

Isabelle Cassar‐Malek Brigitte Picard Catherine C. Jurie Anne Listrat Michel Guillomot

We have recently reported that maturation of the skeletal muscle is delayed in cloned calves during their first year postnatally. This delay could originate from perturbations in fetal myogenesis. The aim of this study was to evaluate the developmental characteristics of muscle in clones versus animals derived from conventional reproduction. We have characterized the anatomical and biochemical properties of the Semitendinosus muscle of clones versus controls at day 60 and day 260. We have analyzed the contractile and metabolic properties of muscle fibers by measuring the abundance of myosin heavy chain (MyHC) isoforms and activities of metabolic enzymes (LDH, PFK, COX, CS, ICDH), respectively. The spatial repartition of some components of the extracellular matrix (collagen types I, IV, VI, chondroitin-6-sulfate, decorin, and tenascin-X) was also studied. At day 60 we found lower numbers and structural organization of fibers, and a delay in the setup of the extracellular matrix. IGF-2 transcript abundance was lower in clones than in their controls. There was no difference in the expression of VEGF (a growth factor regulating vascularization and myogenesis) and its receptor. At day 260 the muscles of fetal clones have not reached the same degree of differentiation than controls as shown by their lower energy metabolisms and their MyHC pattern. These results show for the first time that disturbances in myogenesis occur early in fetal life in cloned cattle.

Evolution postnatale et variabilite interindividuelle des caracteristiques musculaires chez les bovins limousins

Catherine C. Jurie

Ce travail de these a ete conduit afin d'etudier l'evolution des caracteristiques biochimiques, metaboliques et contractiles du muscle semitendinosus aux ages de 1, 6, 12 et 16 mois chez 45 bovins males limousins, eleves dans des conditions semblables et la variabilite interindividuelle de ces caracteristiques au niveau des muscles semitendinosus et longissimus thoracis chez 147 bovins males limousins abattus a 16 mois. La conversion des fibres rapides oxydoglycolytiques en fibres rapides glycolytiques, la diminution de l'activite isocitrate deshydrogenase et l'accroissement de l'activite lactate deshydrogenase revelent une augmentation du metabolisme glycolytique entre 1 et 12 mois d'age et caracterisent ainsi la periode de croissance. Parmi les caracteristiques musculaires etudiees, seule l'activite lactate deshydrogenase apparait comme un facteur discriminant entre animaux des le jeune age et pourrait ainsi constituer un moyen de predire les caracteristiques musculaires d'un animal a la naissance. Les caracteristiques musculaires etudiees presentent une plus grande variabilite entre animaux que le potentiel de croissance et la composition de la carcasse. Les animaux a croissance ponderale elevee presentent un rapport proteines/adn plus eleve et une activite oxydative plus faible. Ainsi une selection des animaux sur la croissance musculaire ne serait pas opposee a une amelioration de la qualite de la viande. L'ensemble de ce travail suggere une relation entre rapport proteines/adn, taille des fibres, metabolisme glycolytique et potentiel de croissance

The relationship between muscle metabolic pathways and marbling of beef

Jean-François J.-F. Hocquette Catherine C. Jurie Y. Ueda P. Boulesteix Dominique Bauchart

Three muscle types were taken from 4 groups of steers of different genotypes which express either high (Angus, Japanese Black x Angus) or low (Limousin) levels of marbled meat. Expression or activities of different proteins or enzymes controlling energy metabolism were determined. Angus and Crossbred animals were characterised by a more oxidative muscle metabolism (especially a higher cytochrome-c oxidase activity) and a higher protein content of adipocyte fatty acid binding protein. The latter was considered as a good predictor of marbling.
