|
• male Thratm3Ven/Thra+ Thrbtm1Df/Thrb+ mutants exhibited 40% less body weight at 31 days of age compared with Thra+/Thra+ Thrbtm1Df/Thrb+ controls
• similar results were obtained with female mice, although the growth retardation of Thratm3Ven/Thra+ Thrbtm1Df/Thrb+ mutants was less at 22%
|
|
• the delay in eye opening was partially rescued, occurring at day 15.3 in the Thratm3Ven/Thra+ Thrbtm1Df/Thrb+ mutants compared with day 18.6 in the Thra+/Thra+ Thrbtm1Df/Thrb+, and day 14 in the wt mice
