The antiapoptotic protein survivin is widely expressed in most human cancers, including carcinomas of the breast. It is rarely detected in corresponding normal adult tissues. Therefore, survivin comes into the limelight as a promising diagnostic biomarker and prognostic parameter. Immunohistochemically, we examined the expression of this protein in 126(More)
Outbred laboratory mice were inoculated at the age of 5, 10 and 21 days by oral and/or intranasal routes with 2 different (a lethal and a nonlethal) doses of the murine herpesvirus isolate 68 (MHV-68). Severe exudative pneumonia with haematogenous dissemination of the virus to liver, heart muscle, and kidneys developed in the 5-day-old as well as in a part(More)
At least nine of the eleven herpes simplex virus (HSV) glycoproteins so far known have been widely characterised as regards their role in the virus replication cycle. During early virus-to-cell adsorption ("adsorption"), glycoprotein C (gC) interacts with the glycosoaminoglycan (GAG) heparan sulphate (HS), located on the cell membrane surface. This(More)
Newborn white mice were susceptible to peroral (p.o.) infection with murine alphaherpesvirus isolated from free-living Clethrionomys glareolus. Death occurred within 6-8 days in animals infected with the higher virus dose of 4.8 log10 TCID50. Clinical symptoms also occurred in some animals infected with lower doses, while others developed inapparent(More)
BACKGROUND The tumor suppressor gene p53 is a key regulator of cell division and/or apoptosis. Survivin is a multifunctional member of the inhibitor of apoptosis family. Survivin and p53 represent diametrically opposed signals that influence the apoptotic pathway. MATERIAL/METHODS To determine the role of p53 and survivin in basal cell carcinoma (BCC), we(More)
Primary pulmonary hypertension (PPH) is a condition characterized by sustained elevation of pulmonary artery pressure (PAP) without demonstrable cause. The most common symptom at presentation is dyspnea. Other complaints include fatigue, chest pain, syncope, leg edema, and palpitations. Right heart catheterization is diagnostic, showing a mean PAP >25 mmHg(More)
Herpes simplex virus type 1 (HSV-1) strains SC16, ANG, its pathogenic variant ANGpath and the mutants ANG-pathgC18 glycoprotein C (glyC) negative and ANGpathI2-4 (glyE negative) were compared for their ability to spread in DBA-2 mice after peripheral inoculation. Virus infectivity assay in 9 organs at days 2, 3, 4, 5, 6, and 10 post-infection (p.i.) and(More)
Altered cell signaling is the molecular basis for cell proliferation occurring in association with several gamma herpesvirus infections. Three gamma herpesviruses, namely EBV/HHV-4, KSHV/HHV-8 and the MHV-68 (and/or MHV-72) and their unusual cell-pirated gene products are discussed in this respect. The EBV, KSHV as well as the MHV DNA may persist lifelong(More)
