The yeast PAF (yPAF) complex interacts with RNA polymerase II and coordinates the setting of histone marks associated with active transcription. We report the isolation and functional characterization of the human PAF (hPAF) complex. hPAF shares four subunits with yPAF (hCtr9, hPaf1, hLeo1, and hCdc73), but contains a novel higher eukaryotic-specific subunit, hSki8. RNAi against hSki8 or hCtr9 reduces the cellular levels of other hPAF subunits and of mono- and trimethylated H3-Lys 4 and dimethylated H3-Lys 79. The hSki8 subunit is also a component of the human SKI (hSKI) complex. Yeast SKI complex is cytoplasmic and together with Exosome mediates …

The objetive of this study was to detect antibodies against vesicular stomatitis virus (VSV) collared peccaries in (Tayassu tajacu) from farms of Iquitos and Pucallpa, Peru. Blood samples were collected in animals olders than 6 months of age (pregnant females were not included) from a farm in Iquitos (n = 21) and from four farms in Pucallpa (n = 47), for detection of antibodies against Indiana 1 and New Jersey serotype of VSV by viral neutralization test. No specific antibodies against both serotypes of VSV were detected, indicating that the peccaries were not exposed to VSV, and suggesting absence of …

Studies of transgenic mice with accelerated accumulation of mtDNA mutations specifically in the heart lead us to propose that apoptotic signaling and cell death is central to the pathogenesis of mtDNA mutations in aging. It is the cellular response to that apoptotic signaling and the organ?s compensatory response to a loss of cells that specify the phenotype of an accumulation of mtDNA mutations. In the heart, cardiomyocytes induce a vigorous anti-apoptotic, pro-survival response to counteract mitochondrial apoptotic signaling. The heart up-regulates contractility of remaining myocytes in order to maintain cardiac output. We hypothesize that mutant mitochondrial proteins originate apoptotic signaling …

A study was conducted to determine the effect of culling BVDV carrier animals on the seroconversion against BVDV in the new generation of heifers from a dairy herd located in Arequipa, Peru. Blood samples were collected from 6-12 month old females in four sampling periods: January (n = 73), June (n = 48), October 2003 (n = 48), and January 2004 (n = 35) to evaluate their serological against BVDV status and to screen for carrier animals using the virus neutralization and antigen-capture ELISA tests, respectively. The prevalence of BVDV was 80.8 ± 9.0, 56.3 ± 14.0, 50.0 ± 14.2 …
