Summary: Despite advances in treating myocardial infarction, limiting infarct size after reperfusion to prevent heart failure remains a challenge, with factors such as comorbidities and experimental models needing to be considered for effective cardioprotection studies. Studies show that current therapeutic strategies may not fully protect the aging heart from myocardial infarction, prompting the need for potential new cardioprotective strategies targeting the aging heart.

Summary: Activation of STAT3 has been identified as a key cardioprotective signal, both in animal studies and in humans. It upregulates the expression of cardioprotective and anti-apoptotic proteins and also plays a role in mitochondrial function. Two novel aspects of STAT activation in cardioprotection are discussed: genetic variance as a potential confounding variable and the potential cardioprotective effects of sodium-glucose cotransporter 2 inhibitors.

Summary: Cardiovascular diseases, especially acute myocardial infarction (MI), are major causes of death worldwide. DJ-1 protein has been found to play a crucial role in cardioprotection, and systemic administration of recombinant DJ-1 has been shown to reduce infarct size, leukocyte infiltration, apoptosis, and oxidative stress in a mouse model of MI. These effects may be mediated by G-protein-coupled receptor signaling and modulation of immune response. This study provides the first evidence for the extracellular activity of DJ-1 in regulating cardiac injury in vivo.

Summary: This study presents the potential of near infrared dye IR-780 for monitoring and protecting ischemic myocardium from injury. IR-780 selectively enters cardiomyocytes in at-risk heart tissues and can preconditon or administer timely to protect against cell death, myocardial remodeling, and heart failure induced by ischemia and oxidative stress. The dye binds to F0F1-ATP synthase in cardiomyocytes, decreases mitochondrial membrane potential, and slows down mitochondrial energy metabolism, leading to a quiescent mitochondria state and inhibition of mitochondrial permeability transition pore. Moderating mitochondrial function depression could be a targeted approach for developing cardioprotective reagents.

Summary: In this study, RIPC was found to have no cardioprotective effect in rats, based on randomized and blinded in vivo studies in three study centres using different RIPC protocols. However, a systematic review and meta-analysis of in vivo rat models showed that RIPC could reduce infarct size by an average of 21.28%. These results highlight the need for more well-designed and well-reported studies to confirm these findings and develop clinically translatable cardioprotective interventions.

Summary: This study aimed to investigate the potential cardiotoxic and/or cardioprotective effects of the novel lipid-lowering drug bempedoic acid (BA) in a rat model of acute myocardial infarction (AMI). The results showed that chronic BA treatment did not affect cardiac function or infarct size, but significantly reduced the incidence of reperfusion-induced arrhythmias. Therefore, BA treatment may not have cardioprotective effects but demonstrates safety in the ischemic/reperfused heart.

Summary: AP2 forms AP2 CCV with clathrin and other coat proteins, and synapses contain different types of CCV. The stability and composition of CCV are regulated by various factors, including Hsc70 and phosphorylation patterns. The knockout of the AP1/O1B complex disrupts synaptic vesicle recycling and endosomal protein sorting, leading to upregulation of endocytosis. Stable CCV, termed stCCV, have distinct characteristics and specialized functions in synaptic plasticity. The phosphorylation of Hsc70 and the levels of kinases play a crucial role in regulating the stability and disassembly of clathrin in CCV.

Summary: This study reveals that glioma-derived S100A9 can induce microglial M2 polarization, inhibit CD8+ T lymphocytes, and promote immunosuppression. The mechanism is related to the interaction with alpha v133 integrin and subsequent activation of AKT1 in microglia. The expression of S100A9 is positively associated with CD206 expression and negatively correlated with CD8+ T lymphocyte accumulation in the TME, suggesting a potential role of S100A9 in regulating the tumor microenvironment and immune evasion in glioma.

Summary: The replication of DNA requires a complex machinery called the replisome, which is highly conserved across species. One crucial component of the replisome is the CMG helicase complex, which unwinds DNA and coordinates the assembly and function of other replisome components. In this study, the impact of the absence of one copy of the CMG complex genes on the physiology and aging of yeast cells was investigated. The findings showed disruptions in the cell cycle, extended doubling times, and alterations in the biochemical profile of these cells. Importantly, it was found that heterozygous cells for CMG helicase genes exhibited increased reproductive potential and delayed aging. The study also highlighted potential therapeutic targets for cancer treatment using yeast.

Summary: The phosphorylation of p65 and the expression of SUMO1 are increased in cancer tissues of HCC patients, and there is a positive correlation between SUMO1 and phosphorylated p65. SUMOylation of p65 by SUMO1 promotes p65 nuclear import and enhances NF-xB activity. Both SUMOylation and phosphorylation of p65 increase the viability and invasion of hepatoma cells, and decrease cell apoptosis.

Summary: This study investigates the role of cyclic AMP (cAMP) in glycogen metabolism and reveals that cAMP regulates glycogenolysis in opposite directions depending on its site of synthesis within cells and downstream effectors. The canonical tmAC-cAMP-PKA signaling promotes glycogenolysis, while the non-canonical sAC-cAMP-Epac1 signaling suppresses glycogenolysis. This highlights the importance of cAMP microdomain organization for distinct metabolic regulation.
