Biological analyses using a dual-luciferase reporter assay system revealed that the Gln127*-mutant SOX17 protein lost the ability to transcriptionally activate its target gene NOTCH1. Moreover, the Gln127*-mutant SOX17 protein exhibited no inhibitory effect on the function of CTNNB1-encode β-catenin, which is a key player in vascular morphogenesis. This research firstly links SOX17 loss-of-function mutation to familial PAH, which provides novel insight into the molecular pathogenesis of PAH, suggesting potential implications for genetic and prognostic risk evaluation as well as personalized prophylaxis of the family members affected with PAH.This study aimed to identify the serum copeptin levels in patients diagnosed with unstable angina (UA) and evaluate the relationship between the patients' copeptin levels and angiographic severity.A total of 200 patients who were diagnosed with UA and underwent coronary angiography were included in the study. Clinical, electrocardiographic, echocardiographic, and laboratory data (high-sensitivity cardiac troponin T and copeptin levels) as well as The Global Registry of Acute Coronary Events (GRACE) 1.0 risk score were recorded upon admission. Moreover, the Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score was calculated following coronary angiography.We isolated and defined two subgroups within our study population group 1 included patients with non-significant coronary artery disease (CAD) ( less then 50% diameter stenosis, n = 105); group 2 included patients with significant CAD (≥ 50% diameter stenosis, n = 95). The number of cases with a GRACE score higher than 140 was significantly higher in group 2 than in group 1 (P less then 0.001). The SYNTAX scores and copeptin levels were significantly higher in group 2 than in group 1 (P less then 0.001 for both). A positive correlation was observed between the copeptin levels and SYNTAX scores (r = 0.683; P less then 0.001), and the cut-off level of copeptin was 18.3 pmol/L (sensitivity of 74.7%, specificity of 83.8%, and area under the curve of 0.795).This study suggests that it may be beneficial to use conventional scoring systems and serum copeptin levels when identifying high-risk UA patients.The recurrence rate of acute coronary syndrome (ACS) in patients after first-time myocardial infarction (MI) is over ten times higher than in the general population. However, it is unclear whether patients with multiple-time MI have an even higher recurrence rate of MI. This study aimed to compare the recurrence rate in patients with multiple-time MI with the rate in patients after first-time MI. We retrospectively studied 794 consecutive MI patients who were discharged. Recurrent ACS was investigated in patients with previous MI (n = 46) and without previous MI (n = 748). During the follow-up periods (mean ± SD 757 ± 733 days), recurrent ACS occurred in 47 cases without previous MI and in 7 cases with previous MI. Kaplan-Meier analysis revealed that the risk of recurrent ACS was significantly higher in patients with previous MI than in patients without previous MI. ACS recurrence rates one year from the onset were 4.2% in patients without previous MI and 11.9% in patients with previous MI. Landmark analysis revealed that the higher recurrence rate in patients with previous MI was as high as 14.1% from 1 year after the onset to 2 years. In conclusion, the risk of recurrent ACS may be significantly higher in patients with multiple-time MI than in patients after first-time MI.This study aims to evaluate the impact of the coronavirus disease 2019 (COVID-19) pandemic on patient admissions to Hunan's cardiac intensive care units (CCUs).We conducted a retrospective, single-center study. Data were collected from patients who were confirmed to have critical cardiovascular disease and admitted to the CCU of the Second Xiangya Hospital of Central South University, Hunan, from January 23 to April 23, 2020. Compared with the same period in 2019, the results show that the number of hospitalization decreased by 19.6%; the inhospital mortality rate of CCU was decreased (28.57% versus 16.67%; odds ratio (OR), 0.50; 95% confidence interval (CI), 0.251-0.996; P = 0.047); hospital stay was decreased (7.97 versus 12.36, P less then 0.001); hospital emergency percutaneous coronary intervention (PCI) rate in patients with acute coronary syndromes (ACS) significantly decreased (76.00% versus 39.00%, P less then 0.001); among this, the PCI rate of patients with ST-segment elevation myocardial infarction (STEMI) decreased (76.32% versus 55.17%, P = 0.028) as well. https://www.selleckchem.com/products/py-60.html In addition, the number of patients transferred from other hospitals significantly decreased (76.79% versus 56.67%, P = 0.002), and the number of patients transferred from other cities also decreased by 10.75%.During the outbreak of the COVID-19 epidemic in Hunan Province, the number of patients admitted to CCU decreased, as well as the mortality rate; fewer patients with severe cardiovascular disease can be transported to better hospitals from remote rural areas. In addition to epidemic prevention and control, experts in China should focus on improved emergency transport medical services to reduce this impact.E2F transcription factor 2 (E2F2) is a member of the E2F family of transcription factors. The classical view is that some E2Fs act as "activators" and others "inhibitors" of cell cycle gene expression. However, the so-called "activator" E2F2 is particularly enigmatic, with seemingly contradictory roles in the cell cycle, proliferation, apoptosis, inflammation, and cell migration and invasion. How can we rationalize the apparently opposing functions of E2F2 in different situations? This is difficult because different methods of studying E2F2 have yielded conflicting results, so extrapolating mechanisms from an observed endpoint is challenging. This review will attempt to summarize and clarify these issues. This review focuses on genetic studies that have helped elucidate the biological functions of E2F2 and that have enhanced our understanding of how E2F2 is integrated into pathways controlling the cell cycle, proliferation, apoptosis, inflammation, and cell migration and invasion. This review will also discuss the function of E2F2 in cancer and other diseases.
