Última Meat tenderness genetic polymorphisms occurrence and distribution in five Zebu breeds in Mexico Electron. J. Biotechnol. Parra-Bracamonte,Gaspar Manuel; Martínez-González,Juan C; Sifuentes-Rincón,Ana M; Moreno-Medina,Victor R; Ortega-Rivas,Eligio. Background The Zebu cattle are represented by a diverse group of breeds in México. Traditionally these breeds have been associated with the tough beef characteristic. Validated genetic markers have the potential to be included in marker-assisted selection and management programs in order to improve traits such as beef tenderness. The incidence and distribution of Calpain and Calpastatin polymorphisms strongly associated with beef tenderness were estimated in registered cattle of five Zebu breeds in Mexico. Results A low and in some cases null frequency of favorable C allele of CAPN316 was determined in all breeds. Conversely, a more equilibrated frequency in CAPN4751 and CAST loci was observed. Conclusions Although the relatively low occurrence of... Tipo: Journal article Palavras-chave: Calpain; Calpastatin; Frequencies; Genotype; SNP.

The variations in the amounts of milli-calpain and its specific inhibitor in the white muscle of sea bass (Dicentrarchus labrax) during storage at 4 degreesC for up to 7 days were determined after separation by hydrophobic chromatography on a Phenyl Sepharose vel. There was a significant decline in post-slaughter m-calpain activity with an important inter-individual variability in the rate of decrease of the total activity. In contrast with the calpastatin of mammalian post mortem muscles, calpastatin remained constant within fish muscles after death. The initial levels of protease and inhibitor activities, and their behaviour through post mortem storage. are discussed and implications for the mechanism of tenderisation of fish muscle are suggested.

Ano: 2004 URL: http://archimer.ifremer.fr/doc/2004/publication-1683.pdf The inhibitory role of sympathetic nervous system in the Ca2+-dependent proteolysis of skeletal muscle BJMBR Navegantes,L.C.C.; Baviera,A.M.; Kettelhut,I.C.. Mammalian cells contain several proteolytic systems to carry out the degradative processes and complex regulatory mechanisms to prevent excessive protein breakdown. Among these systems, the Ca2+-activated proteolytic system involves the cysteine proteases denoted calpains, and their inhibitor, calpastatin. Despite the rapid progress in molecular research on calpains and calpastatin, the physiological role and regulatory mechanisms of these proteins remain obscure. Interest in the adrenergic effect on Ca2+-dependent proteolysis has been stimulated by the finding that the administration of β2-agonists induces muscle hypertrophy and prevents the loss of muscle mass in a variety of pathologic conditions in which calpains are activated. This review summarizes... Tipo: Info:eu-repo/semantics/article Palavras-chave: Epinephrine; Norepinephrine; Calpastatin; Calpain; Skeletal muscle.
