Its activation upregulates thermogenic genes such as UCP1 and PGC-1α, supporting mitochondrial activity and energy dissipation Loss of TRPV2 impairs UCP1 expression, reduces thermogenic capacity, cold intolerance and increases susceptibility to obesity and insulin resistance, underscoring its essential role in adaptive thermogenesis and metabolic homeostasis [132]. This evidence concerns the gene UCP1 and Insulin resistance.
