Background: Lung adenocarcinoma (LUAD) is associated with high morbidity and mortality rates. Increasing evidence indicates that neutrophil extracellular traps (NETs) play a critical role in tumor progression, metastasis and immunosuppression in the LUAD tumor microenvironment (TME). Nevertheless, the use of NET formation-related genes (NFRGs) to predict LUAD patient survival and response to immunotherapy has not been explored.

Movement of lipoprotein lipase (LPL) from myocytes or adipocytes to the capillary lumen is essential for intravascular lipolysis and plasma triglyceride homeostasis-low LPL activity in the capillary lumen causes hypertriglyceridemia. The trans-endothelial transport of LPL depends on ionic interactions with GPIHBP1's intrinsically disordered N-terminal tail, which harbors two acidic clusters at positions 5-12 and 19-30. This polyanionic tail provides a molecular switch that controls LPL detachment from heparan sulfate proteoglycans (HSPGs) by competitive displacement.

Electronic address:
Liver resection represents a main curative treatment for patients with early-stage hepatocellular carcinoma (HCC), but there is a rather high incidence of postoperative HCC relapse, which severely shortens long-term survival time. Currently, no standard adjuvant strategies are available for preventing HCC relapse in clinical practice. Impaired natural killer (NK) cell anti-tumor immunity has been disclosed as a crucial root of HCC relapse, indicating that reinstating NK cell anti-tumor immunity may show promise to curb HCC relapse.

Background: The neutrophil-mediated generation of neutrophil extracellular traps (NETs) results in an augmented inflammatory response and cellular tissue injury during acute myocardial infarction (AMI). Through the analysis of public database information, we discovered and confirmed putative critical genes involved in NETs-mediated AMI.
Methods: The AMI dataset GSE66360 and the single-cell dataset GSE163465 were downloaded from the Gene Expression Omnibus database.
Inhibition of NETs prevents doxorubicin-induced cardiotoxicity by attenuating IL-18-IFN-γ-Cx43 axis induced cardiac conduction abnormalities.

Doxorubicin-induced cardiotoxicity (DIC) is one of the most severe side effects of doxorubicin, yet the underlying mechanisms remain incompletely understood. Our results showed that Neutrophil extracellular traps (NETs) accumulated in plasma and cardiac tissue after doxorubicin treatment. The inhibition of NETs formation by Pad4 gene ablation significantly attenuated doxorubicin-induced arrhythmia, prolonged survival time and reduced the levels of Troponin T (cTnT) and creatine kinase MB (CK-MB) in mice.
