Exosomes regulate SIRT3-related autophagy by delivering miR-421 to regulate macrophage polarization and participate in OSA-related NAFLD.

Purpose: To analyze the role of and mechanism underlying obstructive sleep apnea (OSA)-derived exosomes in inducing non-alcoholic fatty liver (NAFLD).

Methods: The role of OSA-derived exosomes was analyzed in inducing hepatocyte fat accumulation in mice models both in vivo and in vitro.

Results: OSA-derived exosomes caused fat accumulation and macrophage activation in the liver tissue.

Adipocyte-derived exosomes from obstructive sleep apnoea rats aggravate MASLD by TCONS_00039830/miR-455-3p/Smad2 axis.

A correlation exists between obstructive sleep apnoea (OSA) and the severity of metabolic dysfunction-associated steatotic liver disease (MASLD), OSA can induce more severe MASLD. However, the underlying regulatory mechanism between the two is unclear. To this end, this study explored the role and possible molecular mechanisms of adipocyte-derived exosomes under OSA in aggravating MASLD.

Interactions between angiotensin-converting enzyme-2 polymorphisms and high salt intake increase the risk of hypertension in the Chinese Wa population.

Interactions between angiotensin-converting enzyme-2 () gene polymorphisms and high salt intake increase the risk of hypertension (HTN); however, this association is not well-established in the Chinese Wa population. In this study, we investigated the prevalence and associated factors of HTN in the Chinese Wa ethnic minority in Yunnan Province, China. In addition, we assessed the associations of single nucleotide polymorphisms (SNPs) in with blood pressure and environmental factors.
