Replication with viruses

Tat-independent replication of human immunodeficiency viruses.

The replication of human immunodeficiency retroviruses involves a complex series of events that is regulated at both transcriptional and posttranscriptional levels. The tat gene product is a potent trans-activator of viral transcription and therefore an attractive target for the development of antiviral drugs. Tat-defective HIV-1 proviral DNA clones have been shown previously to be replication ...

Herpes simplex viruses: mechanisms of DNA replication.

Herpes simplex virus (HSV) encodes seven proteins necessary for viral DNA synthesis-UL9 (origin-binding protein), ICP8 (single-strand DNA [ssDNA]-binding protein), UL30/UL42 (polymerase), and UL5/UL8/UL52 (helicase/primase). It is our intention to provide an up-to-date analysis of our understanding of the structures of these replication proteins and how they function during HSV replication. The...

Cancer virotherapy: Targeting cancer cells by microRNA mechanism for selective replication of oncolytic viruses in these cells

Cancer, as one of the most serious public health problems, is the second-leading cause of death in the world after cardiovascular disease. The number of patients and the resulting mortality are increasing worldwide; therefore, early diagnosis, prevention, and effective treatment of cancer are very important. Current treatments such as chemotherapy and radiation therapy are often non-selective a...
