UNLABELLED The E7 oncoprotein of the high-risk human papillomavirus (HPV) plays a major role in HPV-induced carcinogenesis. E7 abrogates the G1 cell cycle checkpoint and induces genomic instability, but the mechanism is not fully understood. In this study, we performed RNA sequencing (RNA-seq) to characterize the transcriptional profile of keratinocytes expressing HPV 16 (HPV-16) E7. At the tra...
The majority of asthma exacerbations are caused by rhinovirus. Currently the treatment of asthma exacerbations is inadequate. Previous evidence suggests that macrolide antibiotics have anti-inflammatory and antiviral effects; however, the mechanism is unknown. We investigated the anti-rhinoviral potential of macrolides through the induction of antiviral gene mRNA and protein. Primary human bron...
The study of human papillomavirus type 16 (HPV-16) replication has been impaired because of the lack of a cell culture system that stably maintains viral replication. Recently, cervical epithelial cell populations that stably maintain HPV-16 replicons at a copy number of approximately 1,000 per cell were derived from an HPV-16-infected patient (W12 cell clone 20863 [W12-E cells]). We used neutr...
Interferon alfa (IFN-alpha) is the primary treatment for chronic hepatitis B. The standard duration of IFN-alpha therapy is considered 16 weeks; however, the optimal treatment length is still poorly defined. We evaluated the efficacy and acceptability of prolonged IFN-alpha treatment in patients with chronic hepatitis B. To investigate whether treatment prolongation could enhance the rate of he...
Newly hatched chickens are more susceptible to infectious diseases than older birds because of an immature immune system. The aim of this study was to determine to what extent host responses to avian influenza virus (AIV) inoculation are affected by age. Therefore, 1- and 4-week (wk) old birds were inoculated with H9N2 AIV or saline. The trachea and lung were sampled at 0, 8, 16 and 24h post-in...
Like the biological clock in the body, replication of each cell type (even different cells of the same organism) follows a timing program. Abnormal function of this timer could be an alarm for a disease like cancer. DNA replication starts from a specific point on the chromosome that is called the origin of replication. In contrast to prokaryotes in which DNA replication starts from a single ...
Mitochondrial DNA (mtDNA) is normally only inherited through the oocyte. However, nuclear transfer (NT), the fusion of a donor cell with an enucleated oocyte, can transmit both donor cell and recipient oocyte mtDNA. mtDNA replication is under the control of nuclear-encoded replication factors, such as polymerase gamma (POLG) and mitochondrial transcription factor A (TFAM). These are first expre...
