research The metabolically protective energy expenditure increase ofPik3r1-related insulin resistance is not explained by Ucp1-mediated thermogenesis
This study found that Pik3r1 Y657* mice, which model human SHORT syndrome, show increased energy expenditure despite insulin resistance, but this is not due to changes in locomotion, thermoregulation, or Ucp1-dependent thermogenesis, suggesting a different metabolic mechanism may protect against lipotoxicity.
