Liver transthyretin (TTR) synthesis and release are exacerbated in insulin-resistant states but are decreased by exercise training, in relation to the insulin-sensitizing effects of exercise. We hypothesized that TTR knockdown (TTR-KD) may mimic this exercise-induced metabolic improvement and skeletal muscle remodeling. Adeno-associated virus-mediated TTR-KD and control mice were trained for 8 weeks on treadmills.

Article Synopsis
  • Extreme hypoxia is a key factor in the progression of pancreatic cancer (PC), with high levels of lncRNA PVT1 and HIF-1α being significant indicators in patients.
  • The study reveals that PVT1 not only activates the transcription of HIF-1α by binding to its promoter but also enhances HIF-1α levels post-translationally.
  • These findings suggest that the positive feedback loop between PVT1 and HIF-1α could be a valuable target for new treatments for pancreatic cancer.

Even though insulin-like growth factor 2 (IGF2) has been reported to be overexpressed in nonalcoholic fatty liver disease (NAFLD), its role in the progression of NAFLD and the potential mechanism remain largely unclear. Using in vitro models, we found that IGF2 was the key overexpressed gene in steatosis, suggesting a possible association between IGF2 and NAFLD. Interestingly, loss-of-function experiments revealed that inhibition of IGF2 protein impaired mitochondrial biogenesis and respiration.

Article Synopsis
  • Exercise helps improve insulin resistance and metabolic disorders, but the specific mechanisms behind this are not fully understood.
  • The study finds that elevated levels of the hepatokine transthyretin (TTR) are linked to insulin resistance in both obese mice and humans, and that exercise can reduce TTR levels while enhancing AMPK activity in muscles.
  • TTR may negatively impact insulin sensitivity by being internalized into muscle cells via Grp78, and its suppression during exercise could be an adaptive response to improve metabolic health.
