The metastatic potential of cells is an important parameter in the design of optimal strategies for the personalized treatment of cancer. Using atomic force microscopy (AFM), we show, consistent with previous studies conducted in other types of epithelial cancer, that ovarian cancer cells are generally softer and display lower intrinsic variability in cell(More)
Increasing evidence supports the existence of a subpopulation of cancer cells capable of self-renewal and differentiation into diverse cell lineages. These cancer stem-like or cancer-initiating cells (CICs) also demonstrate resistance to chemo- and radiotherapy and may function as a primary source of cancer recurrence. We report here on the isolation and in(More)
AIMS To slow tumor progression by reducing migratory tumor cell burden using magnetic nanoparticles (MNPs) functionalized with ligands selective for malignant cell surface receptors. MATERIALS & METHODS Three groups of female C57BL/6 mice (control group I, control group II and experimental group) were intraperitoneally injected with a murine ovarian(More)
A growing body of evidence suggests that the developmental process of epithelial-to-mesenchymal transition (EMT) is co-opted by cancer cells to metastasize to distant sites. This transition is associated with morphologic elongation and loss of cell-cell adhesions, though little is known about how it alters cell biophysical properties critical for migration.(More)
BACKGROUND Ovarian cancer diagnosis is problematic because the disease is typically asymptomatic, especially at the early stages of progression and/or recurrence. We report here the integration of a new mass spectrometric technology with a novel support vector machine computational method for use in cancer diagnostics, and describe the application of the(More)
American trypanosomiasis (Chagas disease) continues to be a significant public health problem, and the therapeutic potential of current antichagasic agents (nifurtimox and benznidazole) is rather limited. Here we report on the antitrypanosomal effect of 1-methoxyspirobrassinol and other indole phytoalexins--secondary metabolites produced by Cruciferous(More)
Camalexin, a major indole phytoalexin of Arabidopsis thaliana, accumulates in various cruciferous plants in response to environmental stress and reportedly displays antimicrobial activities against various plant pathogens. However, its cytotoxicity against eukaryotic cells and potential as a prospective drug for human diseases has been examined only in a(More)
Reactive oxygen species increases in various diseases including cancer and has been associated with induction of epithelial-mesenchymal transition (EMT), as evidenced by decrease in cell adhesion-associated molecules like E-cadherin, and increase in mesenchymal markers like vimentin. We investigated the molecular mechanisms by which Snail transcription(More)
Prostate cancer (PCa) is the second leading cause of cancer-related mortality in men. The prevalent diagnosis method is based on the serum prostate-specific antigen (PSA) screening test, which suffers from low specificity, overdiagnosis, and overtreatment. In this work, untargeted metabolomic profiling of age-matched serum samples from prostate cancer(More)
MicroRNAs (miRNAs) are a class of small RNAs that have been linked to a number of diseases including cancer. The potential application of miRNAs in the diagnostics and therapeutics of ovarian and other cancers is an area of intense interest. A current challenge is the inability to accurately predict the functional consequences of exogenous modulations in(More)
