Features of p53 protein distribution in the corneal epithelium and corneal tear film.

Tumor suppressor protein p53 is the key factor in the regulation of cell proliferation. Its concentration is low in the cytoplasm of most cell types. However, in corneal epithelium cells, abnormally high p53 content is detected.

A significant correlation between C - reactive protein levels in blood monocytes derived macrophages versus content in carotid atherosclerotic lesions.

Background: Atherosclerosis is a complex disease involving different cell types, including macrophages that play a major role in the inflammatory events occurring in atherogenesis. C-Reactive Protein (CRP) is a sensitive systemic marker of inflammation and was identified as a biomarker of cardiovascular diseases. Histological studies demonstrate CRP presence in human atherosclerotic lesions, and we have previously shown that macrophages express CRP mRNA.

The tumor-suppressor gene p53 encodes a phosphoprotein involved in the control of cell growth. p53 expression and function have been documented in malignancy, apoptosis and the aging processes. Recently, p53 has been mapped and characterized in the normal cornea across different species.

Genetic characterization of H5N1 influenza virus that caused new outbreak in Israel at the beginning of 2008.

Our aim was to characterize the A/ck/Israeli/1055/2008 (H5N1) avian influenza virus that was isolated at the beginning of 2008, and to establish the phylogenetic relationship of this isolate to other H5N1 viruses that were recently isolated in adjacent countries. In light of a study of complete nucleotide sequences of all the genes we found that the isolate (year 2008) was closely related to the H5N1 viruses isolated in Egypt, Israel and Gaza in 2006. The Israeli isolate had the hemagglutinin-connecting peptide with a polybasic amino acid insertion.

Genetic characterization of avian influenza viruses isolated in Israel during 2000-2006.

Our aim was to establish the phylogenetic and genetic relationships among avian influenza viruses (AIV) recently isolated from poultry in Israel. During this study we analyzed complete nucleotide sequences of two envelope (hemagglutinin and neuraminidase) and six internal genes (polymerase B1, polymerase B2, polymerase A, nucleoprotein, nonstructural, and matrix) of 29 selected H9N2 and six internal genes of five H5N1 viruses isolated in Israel during 2000-2006. Comparative genetic and phylogenetic analyses of these sequences revealed that the local H5N1 viruses are closely related to H5N1 viruses isolated in European, Asian, and Middle Eastern countries in 2005-2006.

Identification of cytoplasmic p53 protein in corneal epithelium of vertebrates.

The tumour suppressor gene p53 encodes a phosphoprotein involved in the control of cell growth. It's expression and function have been documented in malignancy, apoptosis and the aging processes. Recently, p53 expression has been demonstrated in normal murine tissues, including whole eye.

p53 expression in the normal murine eye.

Purpose: The tumor-suppressor gene p53 encodes a phosphoprotein involved in the control of cell growth. Its expression and function have been documented in malignancy, apoptosis, and other abnormal cell proliferation processes. Recently, expression of p53 has been demonstrated in certain normal tissues, including whole eye.
