OBJECTIVES Previous studies in cell lines and tissues derived from mice lacking genes encoding cyclooxygenase (COX)-1 or -2 have demonstrated compensatory regulation between the two isoenzymes. To determine whether this compensation was driven by a mechanism that controls prostaglandin (PG) levels, we investigated the effects of PG availability on the(More)
Like other Alphaherpesvirinae subfamily members, bovine herpesvirus 1 (BHV-1) establishes latency in sensory neurons. The latency-related RNA (LR-RNA) is abundantly expressed in latently infected sensory neurons. An LR mutant virus with stop codons at the amino terminus of the first open reading frame (ORF) in the LR gene (ORF2) does not reactivate from(More)
Human papillomavirus (HPV) type 16 is the most prevalent high-risk viral genotype associated with cervical cancer. Six distinct phylogenetic clusters of HPVs have been identified and are distributed differently across five continents. HPV16 DNA was extracted from cervicolavage samples from women with normal pap smears. The LCR regions were amplified in(More)
Bovine herpesvirus 1 (BHV-1), like other members of the Alphaherpesvirinae subfamily, establishes latency in sensory neurons. The virally encoded latency-related RNA (LR-RNA) is expressed abundantly in latently infected sensory neurons and encodes several proteins, including ORF2. An LR mutant virus with stop codons at the amino terminus of ORF2 does not(More)
Two new 10-membered lactones, namely, multiplolides A (1) and B (2), were isolated from the broth extract of the fungus Xylaria multiplex BCC 1111. Chemical structures of 1 and 2 were elucidated on the basis of their spectral data. Multiplolides A (1) and B (2) exhibited antifungal activity against Candida albicans with IC(50) values of 7 and 2 microg/mL,(More)
Human papillomaviruses (HPVs) are maintained latently in dividing epithelial cells as nuclear plasmids. Two virally encoded proteins, E1, a helicase, and E2, a transcription factor, are important players in replication and stable plasmid maintenance in host cells. Recent experiments in yeast have demonstrated that viral genomes retain replication and(More)
BACKGROUND Papillomaviruses (PVs) establish a persistent infection in the proliferating basal cells of the epithelium. The viral genome is replicated and maintained as a low-copy nuclear plasmid in basal keratinocytes. Bovine and human papillomaviruses (BPV and HPV) are known to utilize two viral proteins; E1, a DNA helicase, and E2, a transcription factor,(More)
Human papillomavirus (HPV) is a major causative agent of cervical cencer and a number of human cancers. The high‐risk types can be detected in more than 90% of cervical cancer, of which HPV16 is the most common found. The virus establishes a latent infection in basal epithelial cells in which the viral genomes can be stably maintained as extrachromosomal(More)
