Background: A growing body of research suggests that oxidative stress and neuroinflammation are early pathogenic features of neurodegenerative disorders. In recent years, the vitagene system has emerged as a potential target, as it has been shown to have a high neuroprotective power. Therefore, the discovery of molecules capable of activating this system may represent a new therapeutic target to limit the deleterious consequences induced by oxidative stress and neuroinflammation, such as neurodegeneration. Lipoxins are derived from arachidonic acid, and their role in the resolution of systemic inflammation is well established; however, they have become increasingly involved in the regulation of neuroinflammatory and neurodegenerative processes. Our study aimed at activating the NF-E2-related factor 2 (Nrf2)/heme oxygenase 1 (HO-1) redox system and increasing lipoxin A4 for the modulation of antioxidant stress and neuroinflammation through the action of two fungi in a rotenone-induced Parkinson's model.
Methods: During the experiment, mice received , or a combination of the two (200 mg/kg, orally) concomitantly with rotenone (5 mg/kg, orally) for 28 days.
Results: The results obtained highlighted the ability of these two fungi and, in particular, their ability through their association to act on neuroinflammation through the nuclear factor-kB pathway and on oxidative stress through the Nrf2 pathway. This prevented dopaminergic neurons from undergoing apoptosis and prevented the alteration of typical Parkinson's disease (PD) markers and α-synuclein accumulation. The action of and was also able to limit the motor and non-motor alterations characteristic of PD.
Conclusions: Since these two mushrooms are subject to fewer regulations than traditional drugs, they could represent a promising nutraceutical choice for preventing PD.

Anthracycline doxorubicin (DOX) remains the first-line chemotherapeutic drug for the efficient treatment of breast cancer, but its severe cardiotoxicity limits its long-term application in clinical tumor chemotherapy. Until now, the pathogenesis mechanism of DOX-induced cardiotoxicity (DIC) is still not fully understood. According to current studies, the oxidative stress caused by the imbalance of reactive oxygen species (ROS) and reactive nitrogen species (RNS) production and mitochondrial dysfunction in myocardial cells are closely related to DIC.

Background And Objectives: Maternal western-style diets that are high in glucose and fat have well-known cardiovascular effects on offspring, yet the combined influence of such diets during pregnancy is relatively less comprehended. This study investigates the impact of maternal high glucose and fat diet (HGF) on vascular constriction in offspring and the underlying mechanisms.
Methods And Results: Pregnant Sprague-Dawley rats were provided with either HGF or control diets.

Stenotrophomonas maltophilia is an emerging global opportunistic pathogen that causes nosocomial infections. We demonstrated that the superoxide stress-sensing transcriptional regulator SoxR directly modulated the expression of an operon encompassing sodA1 (encoding manganese-containing superoxide dismutase) and fre (encoding putative flavin reductase) by directly binding to the operator site, which was located between the - 35 and -10 motifs of the sodA1 promoter. It is known that upon exposure to the superoxide generators/redox-cycling drugs, the SoxR, which is bound to the operator site, became oxidized.

Background: Acute myocardial infarction (AMI) remains a significant cause of global mortality, exacerbated by ischemia-reperfusion (IR) injury. Myocardial cell pyroptosis has emerged as a critical pathway influencing IR injury severity.
Methods: We aimed to investigate the cardioprotective effects of aerobic exercise on IR injury by examining the modulation of IGFBP2 and its impact on GSDME-dependent myocardial cell pyroptosis.
