AI Article Synopsis

  • The increasing prevalence of non-alcoholic fatty liver disease (NAFLD) in adults and children highlights the need for a non-invasive diagnostic method to accurately assess progression to non-alcoholic steatohepatitis (NASH).
  • Current imaging technologies can only detect fat in the liver, making them inadequate for diagnosing NASH, while liver biopsies are invasive and carry risks.
  • A new technique using in vivo dynamic nuclear polarization-magnetic resonance imaging can accurately diagnose NASH by monitoring early mitochondrial metabolic changes, presenting a promising alternative to biopsies.

Article Abstract

Given the rising incidence of non-alcoholic fatty liver disease (NAFLD) in both adults and children, the development of a non-invasive diagnostic method for assessing disease progression to non-alcoholic steatohepatitis (NASH) has become an important research goal. Currently available non-invasive imaging technologies are only able to assess fat accumulation in the liver. Therefore, these methods are not suitable for a precise diagnosis of NASH. The standard diagnostic technique for NASH, liver biopsy, has several drawbacks, including the higher risk of complications that accompanies invasive procedures. Here, we demonstrated that in vivo mitochondrial redox metabolism was dramatically altered at an early stage, before histopathological changes, and NASH could be accurately diagnosed by in vivo dynamic nuclear polarization-magnetic resonance imaging, with carbamoyl-PROXYL as a molecular imaging probe. In addition, this technique was feasible for the diagnosis of NASH compared with histopathological findings from biopsies. Our data reveal a novel method for monitoring the dynamics of redox metabolic changes in NAFLD/NASH.

Background: Currently there is no way to determine if archived cerebrospinal fluid (CSF) specimens have been properly handled and can be considered suitable for research purposes. Transthyretin (TTR) is abundant in CSF and undergoes a redox reaction that shifts its native proteoform into an S-cysteinylated form. This reaction proceeds spontaneously ex vivo when CSF is thawed, but ceases at storage temperatures of -80°C.

Background: Oxidative stress has been implicated in the pathogenesis of Alzheimer's disease (AD). Nevertheless, whether redox perturbations are associated with cognition and AD pathology in the preclinical AD stages, remains unclear. We examined associations of blood redox markers with AD biomarkers and cognitive performance in older adults without clinical dementia.

Background: Obstructive sleep apnoea (OSA) is the sleep disorder most frequently found in patients with Alzheimer's disease (AD). The intermittent hypoxia (IH) caused by OSA may participate in AD pathogenesis through increase in oxidative damage and inflammation. We aimed to identify inflammatory and redox genes differentially expressed in the blood from AD patients with severe OSA compared with those with nonsevere OSA.

RNF7 (Ring Finger Protein 7) is a key component of CRLs (Cullin-RING-type E3 ubiquitin ligases) and has been found to possess intrinsic anti-ROS capabilities. Aberrant expression of RNF7 has been observed in various tumor types and is known to significantly influence tumor initiation and progression. However, the specific role of RNF7 in glioblastoma remains unclear.

Background: Iron is implicated in Alzheimer's disease (AD) and is bound to β-amyloid (Ab) plaques. AD brains have increased 4-hydroxynonenal (HNE) adducts, a lipid decomposition product bound to proteins originating from iron mediated lipid peroxidation. Increased brain iron may result from cerebral microbleeds which by nature are rich sources of iron.
