The native intermediate filament network within human corneal endothelium was identified by a monoclonal antibody to vimentin intermediate filament protein. Human corneal endothelial cells in tissue culture were shown to react positively to this monoclonal antibody by indirect immunofluorescence microscopy. In cryostat sections of human cornea, only the endothelial cells and keratocytes stained...
Fragments of vimentin, generated by chemical or enzymatic cleavages, were analyzed for their capacity to bind to human inverted erythrocyte membrane vesicles. Only peptides comprising the amino-terminal head domain of vimentin molecules were competent in associating with the membranes. In vitro studies also demonstrated that isolated ankyrin (the major vimentin acceptor site on the membrane) bi...
Liver cirrhosis is one of the most common diseases of Chinese patients. Herein, we report the high expression of a newly identified histone 3 lysine 4 demethylase, retinoblastoma binding protein 2 (RBP2), and its role in liver cirrhosis in humans. The siRNA knockdown of RBP2 expression in hepatic stellate cells (HSCs) reduced levels of α-smooth muscle actin (α-SMA) and vimentin and decreased th...
M2BP (also called 90K) is an interferon-stimulated gene product that is upregulated in HIV-1 infection. A recent study revealed that M2BP reduces the infectivity of HIV-1 by inhibiting the processing of the viral envelope protein. Here we report that in addition to reducing viral infectivity, M2BP inhibits HIV-1 virion production. We provide evidence showing that M2BP inhibits HIV-1 Gag traffic...
In vitro binding studies with isolated bovine lens vimentin and avian erythrocyte membranes reveal the existence of two functionally distinct sets of intermediate filament attachment sites. One population of such receptors is located along the nuclear envelope and comprises polypeptides recognizing the carboxy-terminal tail domain of vimentin. Vimentin associates with these nuclear surface rece...
A total of 53 different cell lines originating from a variety of mammalian species were cultured in vitro and analysed for the presence of vimentin, employing polyacrylamide gradient slab gel electrophoresis in urea/acetic acid as buffer system. Irrespective of the cell culture conditions, and the growth potential and morphology of the cells, vimentin was expressed in all cell lines examined, w...
ove over, vesicles. Intermediate filaments (IFs) are also a major cargo of microtubule-based motor proteins, according to new results from Helfand et al. on page 795. The results M explain how rapid changes in IF structure are produced by transport of nonfilamentous vimentin particles. Dynamic changes in vimentin IF structure occur at the onset of cell spreading, requiring the transport of vime...
Motivation/Background:The metastasis of tumor cells consists steps such as epithelial-mesenchymal transition, transendothelial migration and the formation metastatic colonization. E-Cadherin vimentin are main proteins associated with EMT, whereas MMP-9 is migration.
 Method:We aimed to investigate effects boric acid resveratrol comparatively on metaatatic behaviors MCF-7. 30μM 50μM were ad...
background and aim: salivary gland tumors classification continuously undergoes alternations, especially in the recent years. this study used immunohistochemical markers for distinguishing between polymorphous low-grade adenocarcinoma (plga) and adenocarcinoma carcinoma (adcc) which have several overlapping histological and clinical features. materials & methods: ten adcc and eight plga with fi...
