African swine fever virus (ASFV) causes a highly lethal disease in swine for which neither a vaccine nor treatment are available. Recently, a new class of drugs that inhibit histone deacetylases enzymes (HDACs) has received an increasing interest as antiviral agents. Considering studies by others
African swine fever virus (ASFV) codes for a putative histone-like protein (pA104R) with extensive sequence homology to bacterial proteins that are implicated in genome replication and packaging. Functional characterization of purified recombinant pA104R revealed that it binds to single-stranded DNA
This study describes the sensitization mechanism to thermal stress by histone deacetylase inhibitors (HDACIs) in lung cancer cells and shows that Ku70, based on its acetylation status, mediates the protection of lung cancer from hyperthermia (42.5°C, 1-6 hrs). Ku70 regulates apoptosis by
Here we describe an African swine fever virus (ASFV) protein encoded by the open reading frame 5-AR that shares structural and functional similarities with the family of bacterial histone-like proteins which include histone-like DNA binding proteins, integration host factor, and Bacillus phage SPO1
Non-histone chromatin proteins (NHCP) were isolated from skeletal muscle, left ventricle and liver of swine susceptible to malignant hyperthermia and from controls. These proteins were extracted with phenol buffers and fractionated by polyacrylamide gel electrophoresis. Isoelectrofocusing gel
The activity of a platelet protein kinase that phosphorylates the alpha-chain of fibrinogen and the exogenous substrate histone was evaluated in 28 patients with Argentine hemorrhagic fever, grouped into: 13 mild, 6 moderate and 9 severe clinical forms. Blood samples were obtained before treatment
Pazopanib-a multitargeted tyrosine kinase inhibitor with prominent antiangiogenic effects-has shown promise in the treatment of soft-tissue sarcomas. Hyperthermia has been also applied as an adjunctive treatment to chemotherapy for these malignancies. Here, we show that pazopanib and hyperthermia
Induction of programmed cell death has been described during infection with many different viruses. We have investigated the influence of African swine fever virus (ASFV) on apoptosis of different cell populations during in vitro and in vivo infection. We observed apoptosis in ASFV-infected
Heat shock protein (Hsp) 70 expression can be stimulated by febrile range temperature (FRT). Hsp70 has been shown to be elevated in serum of patients with sepsis, and when released from cells, extracellular Hsp70 exerts endotoxin-like effects through Toll-like receptor 4 (TLR4) receptors.
Hantaviruses cause hemorrhagic fever with renal syndrome (HFRS) and hantavirus cardiopulmonary syndrome (HCPS) in humans. Both diseases are considered to be immunologically mediated but the exact pathological mechanisms are still poorly understood. Neutrophils are considered the first line of
Sera samples of 168 patients with familial Mediterranean fever (FMF) and their 184 first degree relatives were analyzed for the presence of autoantibodies to ssDNA, dsDNA, poly (I), poly (G), cardiolipin, histones, RNP and Ro(SSA), using an enzyme linked immunosorbent assay (ELISA). A similar
The analysis of chromosomal aberrations by premature chromosome condensation (PCC) induced by Calyculin A (Cal) is feasible in tumor biopsies from patients and has the potential to predict sensitivity to radiotherapy. As hyperthermia (HT) improves radiotherapy outcome in certain tumor sites, it was
In this paper we demonstrate an increase in thermoresistance of resting Reuber H35 cells upon growth stimulation by serum-containing medium: late G1/early S-phase cells were thermoresistant as compared with G0 phase cells. Increase of thermoresistance during early cell cycle runs parallel with
Pestiviruses are pathogens of cloven-hoofed animals, belonging to the Flaviviridae. The pestiviral particle consists of a lipid membrane containing the three envelope glycoproteins Erns, E1, and E2 and a nucleocapsid of unknown symmetry, which is composed of the Core protein and the viral
