These results were confirmed in a more recent study by the same group, in which finerenone but not spironolactone, increased the recruitment of brown adipocytes as well as the expression of UCP-1, PGC1-α, and β-3 adrenoreceptor in interscapular BAT of very HFD-fed mice, with a concurrent improvement in insulin resistance as indicated by a significant reduction of HOMA-IR index. Here, UCP1 is linked to Insulin resistance.
