RNF219 Promotes Nasopharyngeal Carcinoma Progression by Activating the NF-κB Pathway.

AI Article Synopsis

Article Abstract

In Southeast Asia, the prevalence of nasopharyngeal carcinoma (NPC) is high; however, the molecular mechanism governing the progression of NPC is unclear. The results of the present study revealed upregulation of ring finger protein 219 (RNF219) expression in NPC tissues and cells. Overexpression of RNF219 enhanced NPC cell invasion, migration, and proliferation; whereas knockdown of RNF219 had the opposite effects. Mechanistically, RNF219 activated the nuclear factor kappa B (NF-κB) pathway, mainly reflected by increased p65 nuclear translocation, and increased NF-κB pathway target gene expression. NF-κB pathway inhibition in cells overexpressing RNF219 resulted in reduced invasion, migration, and proliferation, confirming that progression of NPC was promoted by RNF219-mediated NF-κB pathway activation. In addition, the expression of RNF219 correlated positively with the activity of the NF-κB pathway, verifying that RNF219 regulates the activity of the NF-κB pathway in the clinical setting. Our results identified a novel therapeutic target that could promote the development of novel treatments for NPC.

Background: Nicastrin, a subunit of the γ-secretase complex, is encoded by the NCSTN gene and regulates notch signaling, it is involved in the pathogenesis of hidradenitis suppurativa (HS), Alzheimer disease (AD), and liver cancer. However, the animal models for studying HS are relatively scarce.

Methods: CRISPR/Cas-mediated genetic engineering was used to generate targeted knockout offspring mice (C57BL/6J).

Anthracycline doxorubicin (DOX) remains the first-line chemotherapeutic drug for the efficient treatment of breast cancer, but its severe cardiotoxicity limits its long-term application in clinical tumor chemotherapy. Until now, the pathogenesis mechanism of DOX-induced cardiotoxicity (DIC) is still not fully understood. According to current studies, the oxidative stress caused by the imbalance of reactive oxygen species (ROS) and reactive nitrogen species (RNS) production and mitochondrial dysfunction in myocardial cells are closely related to DIC.

The role of MAPK pathway in gastric cancer: unveiling molecular crosstalk and therapeutic prospects.

J Transl Med

December 2024

Department of General Surgery, The Lu'an Affiliated Hospital of Anhui Medical University, Lu'an People's Hospital, Lu'an, 237000, China.

Gastric cancer remains a significant health burden globally, especially prevalent in Asian and European regions. Despite a notable decline in incidence in the United States and Western Europe over recent decades, the disease's persistence underscores the urgency for advanced research in its pathogenesis and treatment strategies. Central to this pursuit is the exploration of the mitogen-activated protein kinase (MAPK) pathway, a pivotal cellular mechanism implicated in the complex processes of gastric cancer development, including cellular proliferation, invasion, migration, and metastasis.

Mechanical ventilation (MV) remains a cornerstone of critical care; however, its prolonged application can exacerbate lung injury, leading to ventilator-induced lung injury (VILI). Although previous studies have implicated ferroptosis in the pathogenesis of VILI, the underlying mechanisms remain unclear. This study investigated the roles of ferritinophagy in ferroptosis subsequent to VILI.

Electroacupuncture ameliorates inflammatory pain through CB2 receptor-dependent activation of the AMPK signaling pathway.

Department of Neurobiology, School of Basic Medicine, Tongji Medical College, Key Laboratory of Neurological Diseases of Hubei Province and National Education Ministry, Huazhong University of Science and Technology, Wuhan, 430030, China.

Background: Chronic inflammatory pain is a pervasive condition, and electroacupuncture (EA) is an effective treatment, but its mechanisms are not fully understood. AMP-activated protein kinase (AMPK), a key energy sensor, is involved in pain relief and EA's effects. EA may work by increasing endocannabinoids, upregulating CB2 receptors (CB2R), and stimulating β-endorphin (β-END).
