BACKGROUND Maspin, a recently identified protein related to the family of serpins, is believed to play a role in human breast cancer. In an effort to improve the present methods of detection, we have developed a reverse-transcriptase polymerase chain reaction (RT-PCR) assay for maspin transcript to identify small numbers of mammary carcinoma cells in the(More)
In an attempt to study the frequency and distribution of human herpesvirus-6 (HHV-6) infection both in normal and neoplastic brain tissues in vivo, polymerase chain reaction was used to look for HHV-6 genomes: 1) in samples, obtained at necropsy, from different regions of the brain of immunocompetent adult subjects and of patients who died of AIDS; 2) in(More)
Saliva and peripheral blood mononuclear cells from three patients, two with lymphoproliferative disorders and one suffering from multiple sclerosis, were examined for the presence of human herpesvirus-6 (HHV-6) genome by using the polymerase chain reaction and Southern blot analysis. The search for anti-HHV-6 antibodies, carried out in the sera of the same(More)
We have investigated the expression of Mr 53,000 protein (p53) in total RNA isolated from human peripheral blood mononuclear cells stimulated by phytohemagglutinin, in serum-stimulated human diploid fibroblasts, and in normal and tumor cells of human epithelial colon tissue. We have found that the expression of p53 messenger RNA is growth regulated in human(More)
The unique phenomenon of human herpesvirus-6 (HHV-6) chromosomal integration (CIHHV-6) may account for clinical drawbacks in transplant setting, being misinterpreted as active infection and leading to unnecessary and potentially harmful treatments. We have investigated the prevalence of CIHHV-6 in 205 consecutive solid organ (SO) and allogeneic stem cell(More)
Human herpesvirus 8 (HHV-8), also known as Kaposi's sarcoma associated herpesvirus (KSHV), has been shown to be the causative agent for Kaposi's sarcoma (KS) and to be more prevalent in populations or risk groups at increased risk for KS. HHV-8 infection is rare in children from the US and the UK, but has been reported in African children. In this study we(More)
In chronic myelogenous leukemia (CML) the reciprocal translocation resulting in the Philadelphia chromosome (Ph1) leads to the formation of a chimeric transcriptional unit carrying both c-abl and bcr genetic information whose transcript is a new fused mRNA of 8.5-kilobases (kb) and whose translational product is a 210-kD phosphoprotein with tyrosine kinase(More)
