Active Src localization at focal adhesions (FAs) is essential for cell migration. How this pool is linked mechanistically to the large pool of Src at late endosomes (LEs)/lysosomes (LY) is not well understood. Here, we used inducible Tsg101 gene deletion, TSG101 knockdown, and dominant-negative VPS4 expression to demonstrate that the localization of(More)
Malacoplakia is a granulomatous disease that most frequently involves the urinary tract but also may involve the genital tract, gastrointestinal tract and retroperitoneum. It is believed to be infectious in origin, secondary to a deficiency of intracellular lysosomal digestion, and heretofore considered a chronic problem. We report a case of malacoplakia of(More)
Previous studies reported that the Tumor Susceptibility Gene 101 (TSG101) is upregulated in selected human malignancies, and the expression of exogenous Tsg101 was suggested to transform immortalized fibroblasts in culture. To date, the potential oncogenic properties of Tsg101 have not been examined in vivo owing to the lack of appropriate model systems. In(More)
The Tumor Susceptibility Gene 101 (Tsg101) encodes a multi-domain protein that mediates a variety of molecular and biological processes including the trafficking and lysosomal degradation of cell surface receptors. Conventional and conditional knockout models have demonstrated an essential requirement of this gene for cell cycle progression and cell(More)
A major contributor to cancer mortality is recurrence and subsequent metastatic transformation following therapeutic intervention. Therefore, in order to develop new treatment modalities and improve the efficacy of current ones, it is important to understand the molecular mechanisms that promote resistance to therapy in cancer cells. One pathway(More)
Understanding the molecular mechanisms promoting therapy resistance is important. Previously, we reported that VEGFC can promote cancer cell survival during stress via interaction with its receptor NRP2. While examining the molecular mechanisms involved in this survival, we performed a microarray study in which we identified two genes, WDFY1 and LAMP2,(More)
Neuropilin-2 (NRP2) is a non-tyrosine kinase receptor frequently overexpressed in various malignancies, where it has been implicated in promoting many protumorigenic behaviors, such as imparting therapeutic resistance to metastatic cancer cells. Here, we report a novel function of NRP2 as a regulator of endocytosis, which is enhanced in cancer cells and is(More)
