Association of CAST2, HSP90AA1, DNAJA1 and HSPB1 genes with meat tenderness in Nellore cattle

The objective of this study was to evaluate the association of expression of CAPN1, CAPN2, CAST, HSP90AA1, DNAJA1 and HSPB1 genes with meat tenderness in Nellore cattle. Three experimental groups were selected by shear force (SF): moderately tender (SF=34.3±5.8N), moderately tough (SF=56.8±7.8N), an...

Description
Summary:The objective of this study was to evaluate the association of expression of CAPN1, CAPN2, CAST, HSP90AA1, DNAJA1 and HSPB1 genes with meat tenderness in Nellore cattle. Three experimental groups were selected by shear force (SF): moderately tender (SF=34.3±5.8N), moderately tough (SF=56.8±7.8N), and very tough meat (SF=80.4±15N). Gene expression was evaluated by real-time PCR. Expression of the CAPN1, CAPN2, CAST and CAST1 genes did not differ between groups. Expression of the CAST2 was up-regulated (P
