Intestinal oxygen utilisation and cellular adaptation during intestinal ischaemia–reperfusion injury

  • First Published: 26 December 2024
Intestinal oxygen utilisation and cellular adaptation during intestinal ischaemia–reperfusion injury

During intestinal ischaemia, mitochondrial oxygen uptake is reduced when cellular oxygen partial pressure decreases to below the threshold required to maintain normal oxidative metabolism.

Upon reperfusion, intestinal hypoxia may persist because microcirculatory flow remains impaired and/or because available oxygen is consumed by enzymes, intestinal cells and neutrophils.

Deficiency of ATF3 facilitates both angiotensin II-induced and spontaneously formed aortic aneurysm and dissection development by activating cGAS–STING pathway

  • First Published: 27 December 2024
Deficiency of ATF3 facilitates both angiotensin II-induced and spontaneously formed aortic aneurysm and dissection development by activating cGAS–STING pathway

  1. ATF3 deficiency led to degradation of P21 through ubiquitination, which abolished the G1 phase arrest.

  2. VSMCs had no time window to repair the damaged DNA, leading to generation of micronuclei in cytoplasm.

  3. Cytoplasmic micronuclei facilitating the activation of cGAS–STING pathway, thus inducing the phenotypic switch and apoptosis of VSMCs

The antiarthritic effect of CBR-470-1 in hypoxic environment is to increase the level of NOD-like receptor family pyrin domain containing 3 ubiquitination by decreasing phosphoglycerate kinase 1 activity

  • First Published: 27 December 2024
The antiarthritic effect of CBR-470-1 in hypoxic environment is to increase the level of NOD-like receptor family pyrin domain containing 3 ubiquitination by decreasing phosphoglycerate kinase 1 activity

Hypoxia plays a pro-inflammatory role by increasing phosphoglycerate kinase 1 (PGK1) activity and reducing the binding of the deubiquitinating enzyme ubiquitin-specific peptidase 14 to NOD-like receptor family pyrin domain containing 3 (NLRP3), thereby reducing the ubiquitination level of NLRP3. CBR-470-1, a specific inhibitor of PGK1, can reduce PGK1 activity to reverse the role of hypoxia in the progression of osteoarthritis.

PINK1 modulates Prdx2 to reduce lipotoxicity-induced apoptosis and attenuate cardiac dysfunction in heart failure mice with a preserved ejection fraction

Our investigation discloses a pivotal relationship between PINK1 and Prdx2 in the context of HFpEF.

Annexin A8 deficiency delays atherosclerosis progression

Our work demonstrates a pathogenic role of endothelial Annexin A8 in atherosclerosis. The upregulation of AnxA8 in both human and mice atherosclerotic plaques strongly suggest that AnxA8 promotes disease progression through regulation of adhesion molecules expression and influx of immune cells to the intima. Therapeutic interventions to reduce AnxA8 expression in endothelial cells may delay atherosclerosis progression.
