Ischemia-reperfusion (I/R) injury, a multifaceted pathological process, occurs when the prolongation of reperfusion duration triggers ferroptosis-mediated myocardial damage. Isoliquiritigenin (ISL), a single flavonoid from licorice, exhibits a wide range of pharmacological impacts, but its function in ferroptosis caused by myocardial I/R injury remains unclear. This study delved into the protective effect of ISL on myocardial I/R injury-induced ferroptosis and its mechanism.

Background: Ischemic heart disease (IHD) is a major global health concern, and its burden among young adults aged 25-49 years remains underexplored. This study aims to provide a comprehensive assessment of the global burden and trends of IHD over the past 30 years (1990-2019) among this age group, as well as to analyze the health inequalities related to socioeconomic development.

Methods: Data from Global Burden of Disease Study 2019 (GBD 2019) were utilized to analyze the prevalence, mortality, and disability-adjusted life years (DALYs) rate of IHD among young adults globally.

Background: Oxidative stress and inflammatory reaction play critical roles in acute myocardial infarction (AMI). Isoliquiritigenin (ISL), a flavonoid monomer extracted from licorice, has been found to have antioxidant and anti-inflammatory effects in cancer studies. Here, we tested the effect and underlying mechanisms of ISL on ischemia-induced myocardial injury in a mouse AMI model.

Long non-coding RNAs (lncRNAs) have been shown to play critical roles in various cell biological processes. However, the mechanism of lncRNAs in acute myocardial infarction (AMI) is not fully understood. Previous studies showed that lncRNA N1LR was down-regulated in ischemic cerebral stroke and its up-regulation was protective.

Despite being the most common human neuroendocrine tumor, the pathogenesis of pituitary adenomas (PAs) is still unclear. Long non-coding RNA (lncRNA) is involved in a variety of physiological and pathological processes, and has been shown to play a key role in the process of tumor instigation and development by affecting the proliferation, migration, invasiveness, and metastasis of tumor cells. Therefore, lncRNAs may be used as diagnostic and prognostic markers of tumors.

Objective To establish and improve a primary culture method of mouse pulmonary artery smooth muscle cells (PASMCs), and explore the effects of different hypoxic conditions on the proliferation, migration, and apoptosis of PASMCs. Methods Under sterile conditions, pulmonary arteries were isolated from male mice and PASMCs were obtained using an improved method of tissue piece inoculation through digesting with trypsin. Cell morphology was observed under an inverted phase-contrast microscope, and cell growth curve was plotted by cell counting.

Triptolide is the predominant active component of the Chinese herb Tripterygium wilfordii Hook F (TwHF) that has been widely used to treat several chronic inflammatory diseases due to its immunosuppressive, anti-inflammatory, and anti-proliferative properties. In the present study, we elucidated the cardioprotective effects of triptolide against cardiac dysfunction and myocardial remodeling in chronic pressure-overloaded hearts. Furthermore, the potential mechanisms of triptolide were investigated.
