Even a low dose of tamoxifen profoundly induces adipose tissue browning in female mice.

ABSTRACT:

Background

Tamoxifen-inducible Cre/lox site-specific recombination technology has been widely used to generate conditional transgenic mice. As an estrogen receptor ligand, tamoxifen itself potentially affects energy metabolism, which may confound interpretation of data especially in metabolic studies. Considering sexual dimorphism, in this study, the effects of low-dose tamoxifen administration on energy metabolism, and browning of adipose tissues in female and male mice were investigated.

Methods

Female and male C57/BL6 mice were injected with tamoxifen oil solution (i.p.) and then housed at both room temperature (23 ± 2 °C) and cold environment (6 ± 1 °C). Serum, brown and white adipose tissues were obtained, and the effects of tamoxifen administration on energy metabolism
