Levels of A serum T3; B T4; C the ratio of T3 to T4; and D BAT UCP1 expression of striped hamsters subjected to food restriction and refed ad libitum. During ad libitum refeeding period, animals were maintained at 23 °C (CON), intermittently exposed to 5 °C for 2 h per day (ICE-2 h/d), 12 h per day (ICE-12 h/d), or persistently exposed to 5 °C (PCE). ns = non-significant difference between the two groups; * = significant difference between the two groups (P < 0.05), ** = P < 0.01. The blots in panel D were cut prior to hybridisation with antibodies
