Figure Lengend Snippet: ROCK2-mediated thermogenic gene expression may occur through the JNK/FOXO1/UCP1 axis (A) Western blotting and quantification of FOXO1 in sWAT from male WT mice housed at room or cold temperature for 3 h ( n = 4 mice per group). (B) Ucp1 expression in sWAT from male WT mice housed at 4 °C for 0, 3, 6, or 12 h ( n = 4 mice). (C) Ucp1 expression in sWAT harvested from control mice and then treated with 40 μM isoproterenol (Iso) and/or 4 μM FOXO1 inhibitor (AS1842856) for 6 h ( n = 4 wells per group). (D) Foxo1 expression in sWAT from male control and AdR2KO mice housed at RT or cold for 3 h ( n = 4 mice). (E) Western blotting and quantification of nuclear FOXO1 (nFOXO1), cytoplasmic FOXO1 (cFOXO1), and total FOXO1 (tFOXO1) in sWAT from male control and AdR2KO mice housed at RT or cold for 3 h ( n = 3 mice). (F) Western blotting and quantification of phosphorylated JNK (pJNK) and total JNK (tJNK) in sWAT from male WT mice housed at RT or cold for 3 h ( n = 3 mice). (G) Foxo1 expression in sWAT harvested from control mice and then treated with 40 μM isoproterenol (Iso) and/or 100 μM JNK inhibitor (SP600125) for 6 h ( n = 6 wells per group). (H) Western blotting and quantification of pJNK and tJNK in sWAT from control and AdR2KO mice housed at RT or cold for 3 h ( n = 3 mice). (I) Foxo1 and (J) Ucp1 expression in differentiated primary adipocytes from sWAT of control and AdR2KO mice. After differentiation for 8 days, mature adipocytes were treated with or without 10 μM isoproterenol (Iso), 1 μM AS1842856, or 50 μM SP600125 for 6 h n = 5–6 wells in (I); n = 3–8 wells in (J). (K) The mRNA levels of Mapk8 (encodes JNK1), Foxo1 , Ppargc1a , and Ucp1 in mature mouse adipocyte cells, 3T3-L1. Adipocytes were transfected with siRNAs for 72 h and then treated with 10 μM isoproterenol (Iso) for 6 h ( n = 6 wells per group). (L) The mRNA levels of Foxo1 , Ppargc1a , and Ucp1 in differentiated mouse primary adipocytes from sWAT of control and AdR2KO mice. Adipocytes were transduced with low ( Foxo1L ) and high ( Foxo1H ) MOI of AAV-8 containing mouse Foxo1 plasmid for 7 days and then treated with 20 μM isoproterenol (Iso) for 16 h ( n = 8 wells per group). The immunoblot images are representative of at least three independent experiments. p values were determined by the two-tailed Student’s t test (A and F) or one-way ANOVA with Tukey’s multiple comparisons test (B-E and G-L). All data are presented as the mean ± SEM of at least three independent biological replicates. See also and . AS: AS1842856; SP: SP600125.
