The acyclic nucleotide analogue (S)-9-(3-hydroxy-2-phosphonylmethoxypropyl)adenine [(S)-HPMPA] is a potent and selective inhibitor of African swine fever virus (ASFV) replication. Using the DNA-DNA hybridization technique with plasmid pRPEL-2 as probe, we have shown that (S)-HPMPA exerts a specific,
Blood platelets from malignant hyperthermia patients share the same defect as skeletal muscle. This could be verified by the effect of halothane on the energy metabolism of blood platelets under optimal experimental conditions. The sensitivity of changes in adenine nucleotide metabolization to
Protein pB119L of African swine fever virus belongs to the Erv1p/Alrp family of sulfhydryl oxidases and has been described as a late nonstructural protein required for correct virus assembly. To further our knowledge of the function of protein pB119L during the virus life cycle, we have investigated
Hyperthermia has been shown in vitro and in vivo to potentiate the effects of ionizing irradiation. Previous studies found that hyperthermia alters the metabolism of adenosine diphosphate (ADP)-ribose polymers required for recovery from DNA damage and that poly(ADP-ribose) polymerase activity is
We have demonstrated recently that CICR (Ca2+-induced Ca2+ release) activity of RyR1 (ryanodine receptor 1) is held to a low level in mammalian skeletal muscle ('suppression' of the channel) and that this is largely caused by the interdomain interaction within RyR1 [Murayama, Oba, Kobayashi, Ikemoto
When compared to normal pig sarcoplasmic reticulum (SR), SR from malignant hyperthermia susceptible (MHS) porcine skeletal muscle has been shown to exhibit an increased rate of calcium release, as well as alterations in [3H]ryanodine-binding activity in the presence of microM Ca2+ (Mickelson et al.,
The global trend towards intensive livestock production is associated with increased fecal oral pathogen transmission resulting in a high prevalence of Salmonella. Since many pathogenic Salmonella serovars are often endemic to livestock production systems, it is desirable to develop a vaccine that
Salmonella DNA adenine methylase (Dam) mutants that lack or overproduce Dam are highly attenuated for virulence in mice and confer protection against murine typhoid fever. To determine whether vaccines based on Dam are efficacious in poultry, a Salmonella Dam(-) vaccine was evaluated in the
Intensive livestock production and management systems are associated with increased fecal-oral pathogen transmission and a resultant high prevalence of multiple Salmonella serovars in many large dairy farms and feedlots. Thus, it is imperative to develop livestock vaccines that are capable of
Salmonella enterica serovar Typhimurium is highly virulent and mediates robust interferon (IFN)-stimulated gene (ISG) induction, whereas bacterial mutants that lack the DNA adenine methylase (Dam) are attenuated, elicit a reduced ISG activation profile, and establish immunity to murine typhoid
Mutants of Salmonella enterica serovar Typhimurium deficient in DNA adenine methylase (Dam) are attenuated for virulence in mice and confer heightened immunity in vaccinated animals. In contrast, infection of mice with wild-type (WT) strains or flagellin-deficient mutants of Salmonella causes
Several inhibitors of S-adenosylhomocysteine (AdoHcy) hydrolase have been found to selectively suppress the replication of African swine fever virus (ASFV) in Vero cells. Of the compounds tested, 3-deazaneplanocin A proved to be the most potent and selective inhibitor of ASFV replication. Its
