New World primates develop T-cell lymphomas on infection with Herpesvirus saimiri. To investigate the oncogenic potential of the Tip gene of Herpesvirus saimiri strain C488, we tried to establish transgenic mice that should express Tip under control of a constitutive promoter. Although transgene-positive embryos were found, lines could not be established. However, using a system in which the transgene has to be activated by a Cre recombinase-mediated deletion, we were able to obtain several Tip transgenic lines. At high expression levels, the mice developed T-cell lymphomas. Thus, Tip can induce lymphomas and is therefore very likely responsible for the oncogenicity of Herpesvirus saimiri.

    An association between human herpesvirus 8 (HHV8) and multiple myeloma (MM) has been reported, though most studies have not confirmed such association. To follow-up on a previous prospective seroepidemiological study, where HHV8 tended to associate with MM risk, we linked five large serum banks...

    Autosomal dominant polycystic kidney disease (ADPKD) is common and is a major cause of renal failure. Although the genetics of ADPKD are well known and have led to the discovery of polycystins, a new protein family, the pathogenesis of the disease remains largely unknown. Recent studies have...
