We have shown previously that distinct Mena isoforms are expressed in invasive and migratory tumor cells in vivo and that the invasion isoform (Mena(INV)) potentiates carcinoma cell metastasis in murine models of breast cancer. However, the specific step of metastatic progression affected by this isoform and the effects on metastasis of the Mena11a isoform,(More)
We report a technique to evaluate the same tumor microenvironment over multiple intravital imaging sessions in living mice. We optically marked individual tumor cells expressing photoswitchable proteins in an orthotopic mammary carcinoma and followed them for extended periods through a mammary imaging window. We found that two distinct microenvironments in(More)
We report on the development of a new SYBR Green I-based plate assay for analyzing the activities of antimalarial drugs against intraerythrocytic Plasmodium falciparum. This assay is considerably faster, less labor-intensive, and less expensive than conventional radiotracer (e.g., [3H]hypoxanthine and [3H]ethanolamine)-based assays or P. falciparum lactate(More)
In the previous paper [Gligorijevic, B., et al. (2006) Biochemistry 45, pp 12400-12410], we reported on a customized Nipkow spinning disk confocal microscopy (SDCM) system and its initial application to DIC imaging of hemozoin within live, synchronized, intraerythrocytic Plasmodium falciparum malarial parasites. In this paper, we probe the biogenesis as(More)
The lex ica1 representation of Serbo-Croatian nouns was investigated in a lexical decision task" Because Serbo-Croatian nouns are declined, a noun may appear in one of several grammatical cases distinguished by the inflectional morpheme affixed to the base form. The grammatical cases occur with different frequencies although some are visually and(More)
Invadopodia are proteolytic membrane protrusions formed by highly invasive cancer cells, commonly observed on substrate(s) mimicking extracellular matrix. Although invadopodia are proposed to have roles in cancer invasion and metastasis, direct evidence has not been available. We previously reported that neural Wiskott-Aldrich syndrome protein (N-WASP), a(More)
While it has been established that a number of microenvironment components can affect the likelihood of metastasis, the link between microenvironment and tumor cell phenotypes is poorly understood. Here we have examined microenvironment control over two different tumor cell motility phenotypes required for metastasis. By high-resolution multiphoton(More)
We previously customized a Nipkow spinning disk confocal microscope (SDCM) to acquire 4D data for live, intraerythrocytic malarial parasites [Gligorijevic B, McAllister R, Urbach JS, Roepe, PD. Spinning disk confocal microscopy of live, intraerythrocytic malarial parasites. 1. Quantification of hemozoin development for drug sensitive versus resistant(More)
Characterizing biological mechanisms dependent upon the interaction of many cell types in vivo requires both multiphoton microscope systems capable of expanding the number and types of fluorophores that can be imaged simultaneously while removing the wavelength and tunability restrictions of existing systems, and enhanced software for extracting critical(More)
Analysis of the individual steps in metastasis is crucial if insights at the molecular level are to be linked to the cell biology of cancer. A technical hurdle to achieving the analysis of the individual steps of metastasis is the fact that, at the gross level, tumors are heterogeneous in both animal models and patients. Human primary tumors show extensive(More)
