Cardiovascular diseases are one of the most common complications of type 2 diabetes. They are considered the leading cause of death among diabetics. One of the mechanisms underlying diabetic cardiovascular complications is oxidative stress. Many phenolic acids are regarded as antioxidants. The aim of the study was to investigate the effect of rosmarinic acid (RA) and sinapic acid (SA) on oxidative stress parameters in the cardiac tissue and serum of type 2 diabetic female rats. Additionally, the effect of these compounds on glucose homeostasis and lipid profile in the serum was evaluated. Type 2 diabetes was induced with high-fat diet and streptozotocin. RA at the doses of 10 and 50 mg/kg and SA at the doses of 5 and 25 mg/kg were administrated orally for 28 days. Untreated diabetic rats exhibited unfavorable changes in glucose metabolism and lipid profile. Changes in the enzymatic and non-enzymatic markers indicated the onset of oxidative stress in these animals. The results showed that the higher doses of the tested phenolic acids-50 mg/kg of RA and 25 mg/kg of SA-revealed beneficial effects on oxidative stress in the cardiac tissue of diabetic rats.

Translation initiation, which involves numerous protein factors and coordinated control steps, represents the most complicated process during eukaryotic translation. However, the roles of eukaryotic translation initiation factor (eIF) in filamentous fungi are not well clarified. In this study, we investigated the function of eIF2Bα in Aspergillus oryzae, an industrially important filamentous fungus.

Exposure to vanadium (V) occurs through the ingestion of contaminated water, polluted soil, V-containing foods and medications, and the toxicity and absorption during the small intestine phase after oral ingestion play crucial roles in the ultimate health hazards posed by V. In this study, the human colon adenocarcinoma (Caco-2) cells were selected as an intestinal absorption model to investigate the uptake and cytotoxicity of vanadyl sulfate (VOSO) and sodium orthovanadate (NaVO). Our results confirmed the cytotoxic effects of V(IV) and V(V) and revealed a greater toxicity of V(IV) than V(V) towards Caco-2 cells.

The study aimed to elucidate the underlying pharmacological mechanism of the traditional Chinese medicine Pue in ameliorating myocardial ischemia-reperfusion injury (MIRI), a critical clinical challenge exacerbated by reperfusion therapy. In vivo MIRI and in vitro anoxia/reoxygenation (A/R) models were constructed. The results demonstrated that Pue pretreatment effectively alleviated MIRI, as manifested by diminishing the levels of serum CK-MB and LDH, mitigating the extent of myocardial infarction and enhancing cardiac functionality.

Loss-of-function mutations in PARK7, encoding for DJ-1, can lead to early onset Parkinson's disease (PD). In mice, Park7 deletion leads to dopaminergic deficits during aging, and increased sensitivity to oxidative stress. However, the severity of the reported phenotypes varies.

Nuclear speckles are membraneless organelles that associate with active transcription sites and participate in post-transcriptional mRNA processing. During the cell cycle, nuclear speckles dissolve following phosphorylation of their protein components. Here, we identify the PP1 family as the phosphatases that counteract kinase-mediated dissolution.
