The metabolic pathway of aerobic glycolysis in tumor cells has garnered significant attention in tumor research because of its high activation in cancer cells. Previous research conducted by our team has demonstrated that Apolipoprotein M (APOM) exhibits potential as a factor against liver cancer. However, further investigations are needed to elucidate the precise approach and mechanism that are involved in this process.

Astrocytes participate in brain clearance of extracellular proteins and metabolites, through the activity of the water channel aquaporin-4 (AQP4), which can be deregulated in stress-related disorders, impairing brain waste clearance. The present study investigates the impact of dexamethasone (Dexa), a synthetic glucocorticoid used as a simplified in vitro stress model, on astrocytic AQP4 and its modulation by adenosine A receptors (AR), which blockade reverses conditions related with maladaptive stress, such as anxiety and depression. The clearance of proteins in primary astrocytic cultures, assessed using 5 kDa FITC-dextran and 45 kDa TRITC-dextran uptake, was decreased by a 24 h exposure to 100 nM Dexa.

Inhibition of human concentrative nucleoside transporter 2 (CNT2) could suppress increases in serum urate levels derived from dietary purines. However, the structural basis for substrate recognition of CNT2 is still unknown and only a few inhibitors have been reported. In this study, a homology model of CNT2 was constructed and residues T315, E316, N426, N491, E492, F536 and N538 were identified as binding sites for adenosine through site-directed mutagenesis and a H-adenosine uptake assay.

Head and neck squamous cell carcinoma (HNSCC) is the seventh most common cancer worldwide with a poor prognosis for survival. Risk factors include alcohol and tobacco abuse and infection with human papilloma virus (HPV). To enhance anti-tumor immune responses immunotherapeutic approaches are approved for recurrent metastatic disease but only approx.

Background: Findings have demonstrated that mitochondrial dysfunction is vital to Alzheimer's Disease (AD) pathogenesis and progression. This study explored an innovative treatment strategy involving transfer of polymer-functionalized, healthy mitochondria to AD neurons. We hypothesized that this organelle transplantation approach would restore mitochondrial function and bioenergetics, preventing aberrant neuronal dynamics associated with AD.
