    Summary
    Porcine MYH4-promoter activity also tended to be increased by T3 treatment, but there were no effects of Des(1-3) IGF-I or Dex treatment, whereas average myotube diameter was increased by Des(1-3) IGF-I, but not T3 or Dex.

    C2C12 myoblasts were co-transfected with porcine MYH4-promoter-driven ZsGreen and CMV-driven DsRed expression plasmids.
    Summary · context
    At the onset of differentiation, treatments (dibutyryl cyclic-AMP (dbcAMP), Des(1-3) Insulin-Like Growth Factor-1 (IGF-I), triiodo-l-thyronine (T3) and dexamethasone (Dex)) or appropriate vehicle controls were added and cells maintained for up to four days.
