Really does temperature reduction and norepinephrine have similar effects on the energy metabolism in rat brown adipose tissue?

Context: Heat generation by brown adipose tissue (BAT) in response to temperature reduction seems to be entirely related to sympathetic nervous stimulation.

Objective: To analyse if temperature reduction and norepinephrine may differently affect the expression of proteins related to energy metabolism in BAT.

Materials And Methods: Isolated rats BAT was incubated with/without norepinephrine (10 mol/L, 24 h at 32 °C and 37 °C).

Metabolic differences between white and brown fat from fasting rabbits at physiological temperature.

It has been suggested that activated brown adipose tissue (BAT) shows increased glucose metabolic activity. However, less is known about metabolic activity of BAT under conditions of fasting and normal temperature. The aim of this study was to compare the possible differences in energetic metabolism between BAT and white adipose tissue (WAT) obtained from rabbits under the conditions of physiological temperature and 24 h after fasting conditions.
