A MT1-MMP/NF-κB signaling axis as a checkpoint controller of COX-2 expression in CD133(+) U87 glioblastoma cells

Journal of Neuroinflammation, 2009
Background The CD133(+) stem cell population in recurrent gliomas is associated with clinical features such as therapy resistance, blood-brain barrier disruption and, hence, tumor infiltration.

Stochastic Nanoscale Biophysical Cues as a Basis for the Induction of Glioblastoma‐Like Transcriptional Programs in Astrocytes

Advanced Science, EarlyView.
Stochastic nanoscale physical cues induce glioblastoma (GBM)‐associated transcriptional traits in naïve astrocytes leading to spontaneous formation of spheroids. Cells within spheroids express activated‐MMP2 and a differential gene expression pattern involving P53 and NOTCH3, providing evidence for a role for changes in brain topography, as observed in

Bmi-1 induces radioresistance by suppressing senescence in human U87 glioma cells

Oncology Letters, 2014
Radiotherapy is the main locoregional control modality for a number of types of malignant tumors, including glioblastoma. However, radiotherapy fails to prevent recurrence in numerous patients due to the intrinsic radioresistance of cancer cells.

A Cascade Recognition of Activatable Probe for Fluorescence Navigation Glioblastoma Surgery: Overcoming Blood‐Brain Barrier and Off‐Target Limitations

Advanced Science, EarlyView.
A cascade recognition of activatable probe ANG‐hCy‐MC is used for high‐precision depiction of glioblastoma (GBM) margin. This probe crosses the blood‐brain barrier (BBB) through LRP1 receptor‐mediated transport and provides excellent fluorescence signal contrast between the tumor and normal tissues, thereby enabling ultra‐selective imaging and precise ...

Immediate early gene IEX‐1 induces astrocytic differentiation of U87‐MG human glioma cells [PDF]

Journal of Cellular Biochemistry, 2006
AbstractThe immediate early response gene IEX‐1 is involved in the regulation of apoptosis and cell growth. In order to increase the apoptotic sensitivity to chemotherapeutic drugs and γ‐ray, we attempted to establish U87‐MG human glioma cell line expressing IEX‐1.

Genetically Engineered Multilineage-Differentiating Stress-Enduring Cells as Cellular Vehicles against Malignant Gliomas

Molecular Therapy: Oncolytics, 2017
Malignant glioma, the most common malignant brain tumor in adults, is difficult to treat due to its aggressive invasive nature. Enzyme/prodrug suicide gene therapy based on the herpes simplex virus thymidine kinase (HSVtk)/ganciclovir (GCV) system is an ...

Valorization of the peel and husk of guaraná (Paullinia cupana): oil extraction, chemical composition, cytotoxicity, and antitumor potential

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Guaraná (Paullinia cupana) is a fruit native to the Amazon region. Due to its widespread use, primarily in beverages, its production has grown over the years. The seed is the only commercially valuable part of the fruit so the guaraná production chain generates byproducts, including peel, husk, and spent seed.

Optimizing biophysical properties of cellular niches to enhance stem cell‐derived extracellular vesicle function in musculoskeletal regeneration

BMEMat, EarlyView.
Extracellular vesicles (EVs) derived from stem cells show promise for applications in regenerative medicine, but their scalability and yield remain challenges. This review explores the approaches for biophysical modulations within cell niches on EV properties, discusses the current clinical application of EVs, and provides an outlook on the existing ...
