The X-ray crystal structure of the DNA decamer d(GACCGCGGTC), containing half the human papilloma virus E2 binding site, has been solved from two crystals grown at different ionic conditions (50 mM MgCl2and 50 mM spermine or 1.56 mM MgCl2and 1.56 mM spermine). Despite the variation in salt concentration, the two DNA structures are in a very similar, A-type DNA conformation, with helical axes cu...
Papilloma virus infections of the oral cavity have been long recognized with various clinical expressions characterized as verruca vulgaris, Heck's disease, multiple papilloma and condyloma acuminata. In this paper, we are highlighting a case of verruca vulgaris involving the oral cavity with extensive skin lesions in a nonimmunocompromised 9-year-old boy. Different treatment modalities are dis...
Polydnaviruses, obligatorily associated with endoparasitoid wasps, are unique in that their segmented genome is composed of multiple double-stranded DNA circles. We present here the first cytological evidence that virus segments are integrated in the wasp genome, obtained by using in situ hybridization of virus probes with viral sequences in the chromosomes of a wasp from the braconid family of...
The plant DNA virus African cassava mosaic virus (ACMV) is believed to replicate by a rolling circle mechanism. To investigate complementary-sense DNA (lagging strand) synthesis, we have analysed the heterogenous form of complementary-sense DNA (H3 DNA) from infected Nicotiana benthamiana by two-dimensional agarose gel electrophoresis and blot hybridisation. The presence of an RNA moeity is dem...
XTrack, a rapid, cost-effective diagnostic HIV tropism system, yields predictive results and dissects virus mixtures. It is based on the duplexing of patient samples with selective DNA probes, combined with sequence-based analysis and replicative phenotyping for ambiguous samples.
Viruses can only reproduce by infecting live cells. During their replication, some viruses manipulate the host cell machinery in such a way that may cause the host cell to reproduce out of control and become carcinogenesis. These viruses are known as oncogenic viruses, also named as “tumor viruses” or “cancer viruses”. In 1909, Francis Peyton Rous showed that cancer could be transmitted through...
Abstract Background and Aims: The human papilloma virus was introduced as the major etiological agent in outbreak of cervical cancer in 1970. Since it is very difficult to recognize these viruses and their types using the serological tests and cell culture, molecular methods such as PCR are of great importance. Therefore, in this study, our goal was to use a multiple specific PCR assay on ...
Warts are skin growth caused by human papilloma virus infection. These can be solitary, multiple, smooth, or cauliflower like and usually treated with topical application of medication surgical excision procedures. Homoeopathy plays an important role in treating warts.
The natural history of cancers associated with virus exposure is intriguing, since only a minority of human tissues infected with these viruses inevitably progress to cancer. However, the molecular reasons why the infection is controlled or instead progresses to subsequent stages of tumorigenesis are largely unknown. In this article, we provide the first complete DNA methylomes of double-strand...
