Fig. 9. Increased blood lactate in heat-sensitive MHS patients and its effect on human preadipocyte brown adipogenesis.

Fig. 9

a Blood lactate concentration of non-heat sensitive (n = 5) and heat-sensitive (n = 10) MHS patients carrying RYR1 variants. b, c Representative immunoblots (b) and relative protein levels (c) for the mitochondrial uncoupling protein (UCP1) in differentiation assay of immortalized human preadipocytes from stromal–vascular fraction of brown adipose tissue treated with vehicle control and different dose of ectopic lactate (n = 5 each). d Proposed model of an adaptive thermogenesis enhanced feed-forward cycle of heat-induced heat response in susceptible patients. P values are indicated as Welch’s t test (a, c). All statistical tests are two-sided. Data are represented as mean ± standard deviation (a) and mean ± standard error of the mean (c). Relative protein levels are determined as levels normalized to the level of vehicle-treated controls (c). Source data are provided as a source data file.
