Interestingly, male mice with hepatocyte-specific PHB1 haploinsufficiency (hPHB1-KD) at 6 months displayed features consistent with metabolic dysfunction-associated steatotic liver disease (MASLD), characterized by liver steatosis and impaired glucose tolerance with hyperinsulinemia, while these parameters were unaffected or even mildly improved in age-matched hPHB1-KD females. Here, PHB1 is linked to Hyperinsulinemia.
