AI Article Synopsis

  • - Alzheimer's disease (AD) is linked to negative changes in brain cells caused by issues like low oxygen (hypoxia), inflammation, and other disruptions that affect cell functions and lead to neuron damage.
  • - Hypoxia is shown to contribute to several harmful factors in AD, such as oxidative stress, problems with energy production, and the buildup of toxic proteins, which all play a role in neurodegeneration.
  • - The review explores how oxygen levels impact the development of AD and examines important regulatory proteins involved in the disease, offering insights into potential treatments.

Article Abstract

Alzheimer's disease (AD) is characterized by an adverse cellular environment and pathological alterations in distinct brain regions. The development is triggered or facilitated by a condition such as hypoxia or ischemia, or inflammation and is associated with disruptions of fundamental cellular functions, including metabolic and ion homeostasis. Increasing evidence suggests that hypoxia may affect many pathological aspects of AD, including oxidative stress, mitochondrial dysfunction, ER stress, amyloidogenic processing of APP, and Aβ accumulation, which may collectively result in neurodegeneration. Further investigation into the relationship between hypoxia and AD may provide an avenue for the effective preservation and pharmacological treatment of this neurodegenerative disease. This review summarizes the effects of normoxia and hypoxia on AD pathogenesis and discusses the underlying mechanisms. Regulation of HIF-1α and the role of its key players, including P53, VEGF, and GLUT1, are also discussed.

Following the publication of this paper, it was drawn to the Editors' attention by a concerned reader that certain of the TUNEL assay data shown in Fig. 4B were strikingly similar to data appearing in different form in another article written by different authors at different research institutes that had already been submitted for publication to the journal (which has subsequently been retracted). Owing to the fact that these contentious data had already apparently been submitted for publication prior to the receipt of this paper to , the Editor has decided that this paper should be retracted from the Journal.

Innovative advancements in preclinical imaging have led to the development of cone-beam computed tomography (CBCT) combined with contrast free pulmonary angiography (CFPA), a novel lung scanning technology capable of assessing lung function and pulmonary vascular morphology. This cutting-edge approach integrates CBCT to provide detailed quantification of the pulmonary vascular tree. The application of this technique to image and quantify changes in the pulmonary vascular tree of mice exposed to chronic hypoxia has not been investigated.

Sevoflurane (Sev) has a cardioprotective role in myocardial ischemia/reperfusion injury (MI/RI), but its mechanism has not been fully elucidated. This study aimed to investigate whether the circ_CDR1as/miR-671-5p/HMGA1 axis mediates the cardioprotective effect of Sev in MI/RI. Cardiomyocytes underwent hypoxia/reoxygenation (H/R) treatment was used to simulate MI/RI in vitro.

Effect of age on lung adaptation to high-altitude hypoxia in Tibetan sheep.

Front Vet Sci

December 2024

Gansu Key Laboratory of Herbivorous Animal Biotechnology, Faculty of Animal Science and Technology, Gansu Agricultural University, Lanzhou, China.

After prolonged adaptation to high-altitude environments, Tibetan sheep have developed a robust capacity to withstand hypobaric hypoxia. Compared to low-altitude sheep, various organs and tissues in Tibetan sheep have undergone significant adaptive remodeling, particularly in the lungs. However, whether lambs and adult Tibetan sheep exhibit similar adaptations to high-altitude hypoxia remains unclear.

Granulomas, organized aggregates of immune cells which form in response to (), are characteristic but not exclusive of tuberculosis (TB). Despite existing investigations on TB granulomas, the determinants that differentiate host-protective granulomas from granulomas that contribute to TB pathogenesis are often disputed. Thus, the goal of this narrative review is to help clarify the existing literature on such determinants.
