Induction of three BMP family members and seven FGF family members upon cold exposure. (A) Ucp1 mRNA expression in BAT of male mice kept at 23°C or 4°C for 24 h. (B) Expression of genes encoding for BMP family members in BAT of male mice kept at 23°C or 4°C for 24 h. (C) Expression of genes encoding for FGF family members in BAT of male mice kept at 23°C or 4°C for 24 h. Results were normalized to 18S ribosomal RNA (Rn18s) and beta-2 microglobulin (B2m) with data from mice kept at 23°C defined as ‘1’.Values are averages ± SEM; n = 6; *p < 0.05 vs. 23°C (Mann–Whitney U test).
