The propensity of cancer cells to preferentially undergo anaerobic metabolism despite oxygen being abundant is referred to as the Warburg effect. Measuring cellular metabolism is therefore central to understanding the cellular physiology of cancer cells. The Seahorse XFe Analyzer series allows real-time measurement of cellular metabolism. In the basic assay, two parameters, the oxygen consumption rate (OCR) and the extracellular acidification rate (ECAR), are used to determine real-time changes in the energy needs of live cells: OCR provides a measure of aerobic mitochondrial respiration; ECAR gives a measure of anaerobic glycolysis. Through the use of various respiration inhibitors, the Seahorse assay allows baseline respiration rate and total aerobic and anaerobic ATP production to be determined under a variety of experimental conditions. Here we describe the protocol for completing the Seahorse Real-Time ATP Rate Assay for adherent and suspension cancer cell lines. Depending on individual experimental results, more refined subsequent assays can then be performed to specifically determine, for example, the ability to utilize different substrates by the cell lines in the presence and absence of pharmacological and/or genetic interventions.

Adeno-associated virus (AAV) vectors are widely used in gene therapy, particularly for liver-targeted treatments. However, predicting human-specific outcomes, such as transduction efficiency and hepatotoxicity, remains challenging. Reliable models are urgently needed to bridge the gap between preclinical studies and clinical applications.

Reconstructing bone defects remains a significant challenge in clinical practice, driving the urgent need for advanced artificial grafts that simultaneously promote vascularization and osteogenesis. Addressing the critical trade-off between achieving high porosity/strength and effective bioactivity at safe ion doses, we incorporated strontium (Sr) into β-tricalcium phosphate (β-TCP) scaffolds with a triply periodic minimal surface (TPMS) structure using digital light processing (DLP)-based three-dimensional (3D) printing. Systematically screening Sr concentrations (0-10 mol%), we identified 10 mol% as optimal, leveraging the synergy between the biomimetic TPMS architecture, providing exceptional mechanical strength (up to 1.

Neutrophil extracellular traps (NETs) are DNA-protein structures released during a form of programmed neutrophil death known as NETosis. While NETs have been implicated in both tumor inhibition and promotion, their functional role in cancer remains ambiguous. In this study, we compared the NET-forming capacity and functional effects of NETs derived from lung cancer (LC) patients and healthy donors (H).

Background: Lung cancer remains the leading cause of cancer-related mortality globally, primarily due to late-stage diagnosis, molecular heterogeneity, and therapy resistance. Key biomarkers such as EGFR, ALK, KRAS, and PD-1 have revolutionized precision oncology; however, comprehensive structural and clinical validation of these targets is crucial to enhance therapeutic efficacy.
Methods: Protein sequences for EGFR, ALK, KRAS, and PD-1 were retrieved from UniProt and modeled using SWISS-MODEL to generate high-confidence 3D structures.

Follicular dendritic cell sarcoma (FDCS) is a rare tumour derived from dendritic cells located in B-follicles that play a pivotal role in the adaptive immune response. Surgery is the mainstay of treatment for localized disease; however, the management of unresectable or advanced disease is less well-defined. To date, to the best of our knowledge, there is no established or preferred chemotherapeutic regimen, although a number of regimens (primarily used in lymphomas and sarcomas) have been utilized with suboptimal outcomes.
