Non-coding RNA-related antitumor mechanisms of marine-derived agents.

In the last two decades, natural active substances have attracted great attention in developing new antitumor drugs, especially in the marine environment. A series of marine-derived compounds or derivatives with potential antitumor effects have been discovered and developed, but their mechanisms of action are not well understood. Emerging studies have found that several tumor-related signaling pathways and molecules are involved in the antitumor mechanisms of marine-derived agents, including noncoding RNAs (ncRNAs). In this review, we provide an update on the regulation of marine-derived agents associated with ncRNAs on tumor cell proliferation, apoptosis, cell cycle, invasion, migration, drug sensitivity and resistance. Herein, we also describe recent advances in marine food-derived ncRNAs as antitumor agents that modulate cross-species gene expression. A better understanding of the antitumor mechanisms of marine-derived agents mediated, regulated, or sourced by ncRNAs will provide new biomarkers or targets for potential antitumor drugs from preclinical discovery and development to clinical application.

Predictive value of N-terminal pro-B-type natriuretic peptide (NT-pro BNP) combined with D-dimer for no-reflow phenomenon in patients with acute coronary syndrome after emergency of percutaneous coronary intervention.

Acute coronary syndrome (ACS) is a critical illness in cardiovascular disease. The purpose of this study was to investigate the value of N-terminal pro-B-type natriuretic peptide (NT-proBNP) and D-dimer in predicting the occurrence of no reflow in emergency percutaneous coronary intervention (PCI) in patients with ACS. One hundred and sixty-eight ACS patients were recruited, including 88 patients with normal reflow and 80 patients with no reflow after emergency PCI. The levels of serum NT-proBNP and D-dimer in the patients were detected before PCI, immediately after PCI, 2 hours, and 6 months after PCI. The ROC curve was used to evaluate the predictive value of NT-proBNP and D-dimer in no-reflow phenomenon. Logistic regression model was used to analyze the independent influencing factors of no reflow phenomenon. Logistic regression analysis confirmed that NT-proBNP and D-dimer were independent predictors of the occurrence of no reflow in the total population. The ROC curve showed that the AUC value was 0.909 when NT-proBNP combined with D-dimer. The detection of NT-proBNP combined with D-dimer was helpful to predict the occurrence of no-reflow phenomenon after emergency PCI in ACS patients.
