Abstract Lysine acetylation, a reversible and dynamic post-translational modification, plays pivotal roles in regulating many biological processes in plants. However, the information of lysine acetylation during flower development of woody angiosperm remains unclear. Herein, we identified a total of 667 lysine acetylation sites in 467 proteins in flower buds of Catalpa Bungei. The acetylated proteins were mainly involved in the pathways of carbon metabolism, glycometabolism and oxidative phosphorylation. Using functional enrichment analysis, 61 and 13 acetylated proteins were involved in the glycometabolism and oxidative phosphorylation pathways, respectively. This suggests that lysine acetylated proteins play critical roles in the energy metabolism pathways.… More >

Abstract Post-resuscitation myocardial dysfunction (PRMD) is the most severe myocardial ischemia-reperfusion injury (MIRI) and is characterized by difficult treatment and poor prognosis. Research has shown the protective effects of the rational use of ivabradine (IVA) against PRMD; however, the molecular mechanisms of IVA remain unknown. In this study, an ischemia-reperfusion injury (IRI) model was established using hypoxic chambers. The results demonstrated that pretreatment with IVA reduced IRI-induced cytotoxicity and apoptosis. IVA attenuated mitochondrial damage, eliminated excess reactive oxygen species (ROS), suppressed IRI-induced ATP and NAD⁺ , and increased the AMP/ATP ratio. We further found that IVA increased the mRNA levels of… More >
