MOTS-c triggers thermogenic genes program via the ERK signaling pathway. (AD) The protein levels of phospho-ERK1/2, PGC1α, and UCP1 in adipocytes treated with MOTS-c and immunoreactive bands were quantified by densitometric analysis using ImageJ (n = 4, per group). (EG) The RNA level of thermogenic genes (PGC1α, UCP1, and Dio2) (n = 4, per group). (HK) The level of phospho-ERK1/2, PGC1α, and UCP1 in adipocytes treated with MOTS-c and ERK inhibitor, and immunoreactive bands were quantified by densitometric analysis using ImageJ (n = 4, per group). (LN) The RNA level of thermogenic genes (PGC1α, UCP1, and Dio2) (n = 4, per group). All data are represented as mean ± SEM. Differences between the two groups were determined by a two-tailed Student’s t-test. * p < 0.05, ** p < 0.01, *** p < 0.001, n.s. = not significant.
