Targeted Wnt/β-catenin pathway is considered to be a promising therapy for cancer metastasis. The novel O -(2,4-dinitrophenyl) diazeniumdiolate (JS-K) plays a potent inhibitory role in the proliferation of cancers. In this study, HepG2 and SMMC7721 were used to clarify the efficacy of JS-K inhibition of HCC metastasis. JS-K significantly inhibited cell motility through a wound-healing assay and restrained cell migration and invasion at noncytotoxic concentrations. However, the inhibitory effects of migration and invasion were abolished after the addition of NO scavenger, Carboxy-PTIO. In addition, JS-K inhibited the Wnt/β-catenin pathway by a decrease of p-GSK-3β at Ser9, cytosolic β-catenin, and nuclear β-catenin accumulation whereas an increase of p-β-catenin. Furthermore, the transcription regulators c-Myc, survivin, and Cyclin D1 were down-regulated after treating with JS-K. The inhibitory of the Wnt/β-catenin pathway was reversed after the addition of Carboxy-PTIO or LiCl. Meanwhile, JS-K also inhibited the epithelial-mesenchymal transition (EMT)-mediated cell migration and invasion. The characteristics of the inhibition were reflected by the upregulation of E-cadherin whereas the downregulation of Vimentin, Snail, and Slug. Taking together, these results demonstrated that JS-K inhibited HepG2 and SMMC7721 cells migration and invasion by reversing EMT via the Wnt/β-catenin pathway.

DNA hypomethylation-related expression of hsa-miR-184 contributes to invasive growth of gonadotroph neuroendocrine pituitary tumors.

Gonadotroph neuroendocrine pituitary tumors are among the most common intracranial neoplasms. A notable proportion of these tumors is characterized by invasive growth which hampers the treatment results and worsens prognoses of patients. Increased hsa-miR-184 expression was observed in invasive as compared to non-invasive gonadotroph tumors.

Gastric cancer is the fifth most common cancer and the fourth leading cause of cancer-related deaths worldwide, accounting for nearly 800,000 fatalities annually. ITGAX (Integrin alpha X) is closely associated with immune cells, such as macrophages and dendritic cells. Its involvement in gastric cancer was identified through an analysis of The Gene Expression Omnibus (GEO) database, which highlighted as one of four key gastric cancer-related genes.

The European Union (EU) experienced two major instances of refugee influx: in 2015, refugees, mainly from Syria, Afghanistan and Iraq fled civil war, persecution, and dire conditions in neighbouring countries and in 2022, Ukrainians fled from Russia's full-scale invasion. Fusing theoretical insights on framing and crisification of migration, we ask: How do EU actors frame situations of refugee mass influx? Employing a Discourse Network Analysis, we examine EU representatives' framing of both instances with respect to three analytical foci: (1) who or what they considered to be in crisis, (2) their framing of refugees; and (3) who they saw to be responsible for solving the crisis. We show how, in 2015, EU representatives framed mass displacement predominantly as a crisis at and of Europe's borders, and refugees as threats to Member States' public, economic and cultural security.

By virtue of their ability to bind different growth factors, morphogens and extracellular matrix proteins, heparan sulfate proteoglycans (HSPGs) play a determinant role in cancer cell differentiation and migration. Despite a strong conceptual basis and promising preclinical results, clinical trials have failed to demonstrate any significant advantage of administering heparin to oncology patients. We exploited our anti-heparan sulfate branched peptide NT4 to test the opposite approach, namely, targeting HSPGs to interfere with their functions, instead of using heparin as a soluble competitor in human cell lines from pancreas adenocarcinoma, colon adenocarcinoma, rhabdomyosarcoma and two different breast cancers.

Percutaneous vertebroplasty (PVP) is a widely utilized minimally invasive technique originally developed for the treatment of vertebral compression fractures. It has since expanded to treat osteoporotic vertebral compression fractures, pathologic vertebral fractures resulting from primary or secondary spinal tumors, and traumatic spinal fractures. Despite its benefits, PVP is associated with significant complications, the most common of which is bone cement leakage.
