Quantitative Immunohistochemistry of Estrogen and Progesterone Receptor Positivity in Ovarian Tumors: A Rapid and Reliable Stereological Approach

Several assays exist to determine receptor status in ovarian cancers, like radio ligand binding assays, biochemical analysis, and even Northern blotting. However, patholo- gists generally prefer to judge the presence of biological markers

underlying viral entry and tropism 4 . The virus strains responsible for transmission, which are the predominant virus type isolated from asymptomatic HIV-positive individuals, use CCR5 as a receptor, whereas viruses that emerge later in the course

Analysis of Nuclear Receptor Acetylation

have shown that acetylated core histones are often associated with transcriptionally active chromatin. Acetylation at lysine residues of histone tails neutralizes the positive charge, which decreases the binding ability to DNA and increases the accessibility
