Expression profiling of skeletal muscle in beef cattle treated with steroidal growth promoters

ABSTRACT: In the present study, a oligonucleotide microarray platform is used to compare expression profiles of beef cattle muscle in animals treated with either Dexamethazone (Dex) or Dexamethazone plus 17?-estradiol (Estr) administered at sub-therapeutic dosage, against untreated controls. Seventeen male beef cattle 15-18 months old, around 450 kg mean body weight were randomly allocated in three groups: 6 were untreated (group Ctrl), 5 were administered with dexamethazone via feed 0.75mg/head for 43 days (group D); the last 6 animals were administered via feed for 43 days with Dex (0.75mg/head) and intramuscularly (i.m.) for three times with 17?-oestradiol, 20mg/head, (group DE). Three additional control animals, matching in sex and age, collected in a previous experiment were included in the Ctr
