The E6 oncoprotein derived from tumour-associated human papillomaviruses (HPVs) binds to and induces the degradation of the cellular tumour-suppressor protein p53. A common polymorphism that occurs in the p53 amino-acid sequence results in the presence of either a proline or an arginine at position 72. The effect of this polymorphism on the susceptibility(More)
Human papillomavirus (HPV) E6 proteins inhibit apoptosis in both p53-dependent and p53-independent manners. A key point in apoptosis is the regulation provided by the Bcl-2 family; and in differentiating keratinocytes, in which HPV replicates, the Bak protein is highly expressed. We show that HPV-18 E6 will inhibit Bak-induced apoptosis and this is mediated(More)
BACKGROUND Tamoxifen preserves bone in postmenopausal women, but non-steroidal aromatase inhibitors accelerate bone loss and increase fracture risk. We aimed to study the effect on bone health in a subgroup of women included in the Intergroup Exemestane Study (IES), a large randomised trial that compared the switch to the steroidal aromatase inhibitor(More)
The oncoproteins of small DNA tumor viruses promote tumorigenesis by complexing with cellular factors intimately involved in the control of cell proliferation. The major oncogenic determinants for human adenovirus type 9 (Ad9) and high-risk human papillomaviruses (HPV) are the E4-ORF1 and E6 proteins, respectively. These seemingly unrelated viral(More)
INTRODUCTION The correct interpretation of DXA data is critical to the diagnosis and management of children with suspected bone disease. This study examines the various influences on bone mineral content (BMC), as measured by dual-energy X-ray absorptiometry (DXA). MATERIALS AND METHODS Six hundred and forty-six healthy school children and forty-three(More)
Previous studies have shown that the oncogenic HPV E6 proteins form a complex with the human homologue of the Drosophila tumour suppressor protein, discs large (Dlg). This is mediated by the carboxy terminus of the E6 proteins and involves recognition of at least one PDZ domain of Dlg. This region of E6 is not conserved amongst E6 proteins from the low risk(More)
A general theme that has emerged from studies of DNA tumor viruses is that otherwise unrelated oncoproteins encoded by these viruses often target the same important cellular factors. Major oncogenic determinants for human adenovirus type 9 (Ad9) and high-risk human papillomaviruses (HPV) are the E4-ORF1 and E6 oncoproteins, respectively, and although(More)
The wild-type p53 protein exhibits a common polymorphism at amino acid 72, resulting in either a proline residue (p53Pro) or an arginine residue (p53Arg) at this position. Despite the difference that this change makes in the primary structure of the protein resulting in a difference in migration during sodium dodecyl sulfate-polyacrylamide gel(More)
The isolation and construction of a complete human p53 cDNA and subsequent expression in monkey cells is described. A set of new anti-(human p53) monoclonal antibodies has also been obtained and used to show the expression of the human p53 cDNA in cos-l cells. These antibodies enable the specific detection of human p53, which is synthesised in the presence(More)
The W12 cell line was derived from a low grade cervical lesion, and is unique among HPV16-containing cell lines in carrying its HPV16 genome as a multicopy episome. As such it is thought to be more representative of a premalignant HPV16-induced tumor than the cervical cancers from which other cell lines have been derived. Using the polymerase chain reaction(More)
