Exploiting Modulation Of The Blood-Brain And Blood-Tumor Barrier Permeability By Translational Focused Ultrasound For Therapeutic Delivery To Cns Metastases, Tasneem A. Arsiwala
Exploiting Modulation Of The Blood-Brain And Blood-Tumor Barrier Permeability By Translational Focused Ultrasound For Therapeutic Delivery To Cns Metastases, Tasneem A. Arsiwala
Graduate Theses, Dissertations, and Problem Reports
Transcranial low-intensity focused ultrasound is a unique technology to modulate the integrity of tight endothelial junctions and transiently increase BBB/BTB permeability to enhance therapeutic delivery. Despite promising early studies, present literature lacks agreement on key experimental conditions, which restricts our knowledge and the technique's widespread translation. This dissertation first provides a critical review of the current gaps in knowledge regarding the universal use of LiFUS in preclinical and clinical use. We then identify key parameters for translational and predictable opening of the BBB using a 3T MRI coupled with a clinical device. Our investigation highlights that passive permeability of the …
Alpinia Galanga Extract Induces Senescence In Human Epidermal Growth Factor Receptor 2-Overexpressing Breast Cancer Cells, Riris Istighfari Jenie, Ragil Anang Santoso, Irfani Aura Salsabila, Nadzifa Nugraheni, Edy Meiyanto

Background: Alpinia galanga L. (galangal) is a widely known spice in Southeast Asia. A previous study indicated that its active compounds might effectively inhibit (human epidermal growth factor receptor 2 [HER2])-overexpressing breast cancer cell proliferation. Objective: Our study aimed to investigate the antiproliferation activity of galangal extract (GE) on HER2- overexpressing breast cancer cells by analyzing GE cytotoxicity and its mechanism of action. Materials and Methods: We used HCC1954 cell line as a model. We observed the effect of GE (10–200 μg/mL) on cell growth using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. The modulation of GE on cell cycle, apoptosis, and the intracellular …

Introduction: Hydrazones have been reported for various biological activities, such as anticancer. The presence of the azomethine group (-NHN=CH-) makes these compounds as one of the important classes in many synthetic products. Objective: The aim of this work is to explore the potential of halogenated hydrazones series as breast cancer inhibitors. Methods: In this study, some series of halogenated hydrazones have been synthesized through condensation reaction between halogenated benzaldehydes and phenylhydrazine under microwave irradiation. The structures of the halogenated hydrazoes were confirmed by ultraviolet, fourier-transform infrared, NMR, and gas chromatography-mass spectrometry spectroscopic data. The in silico studies i.e. docking and …

AMPK activation and Ubiquitin Proteasome System (UPS) inhibition have gained great attention as therapeutic strategies for the treatment of certain types of cancers. While AMPK serves as a master regulator of cellular metabolism, UPS regulates protein homeostasis. Although the crosstalk between them is suggested, the relationship between these two important pathways is not very clear. We observed that proteasome inhibition leads to AMPK activation in human breast cancer cells. We report that a variety of proteasome inhibitors activate AMPK in all of the tested cancer cell lines. Our data using Liver Kinase B1 (LKB1)-deficient cancer cells suggests that proteasome inhibitor-induced …

Among the non-cellular microenvironmental factors that contribute to malignancy of solid tumors is an acidic peritumoral pH. The first objective was to determine if an acidic extracellular pH observed in vivo (i.e., pHe 6.8) affects the activity of proteases, such as cathepsin B, that contribute to degradation of collagen IV by tumor cells when grown in biologically relevant three-dimensional cultures. At pHe 6.8 there were increases in pericellular active cysteine cathepsins and in degradation of DQ-collagen IV, which was partially blocked by a cathepsin B inhibitor. Imaging probes for active cysteine cathepsins localized to tumors in vivo. The amount of …
