Research Concerning the PCR-RFLP/Eco88I Polymorphism of STAT5A Gene in Romanian Simmental Cattle
Abstract
STAT5 (Signal transducers and activator of transcription) is a member of STATs family that mediates the action of peptide hormones and cytokines within target cells (prolactin signaling can activate transcription of milk protein genes). Using the PCR_RFLP technique and Eco88I enzyme, the C - T nucleotide substitution at position 6853 was detected within exon 7 of the bovine STAT5A gene a population of Romanian Simmental breed. In order to study the relationship between STAT5A/Eco88I polymorphism and milk performance traits, the data for milk production that included milk yield, protein and fat yield, fat and protein percentage were used.a) Authors retain copyright and grant the journal right of first publication with the work simultaneously licensed under a Creative Commons Attribution License that allows others to share the work with an acknowledgement of the work's authorship and initial publication in this journal.
