The lack of small-animal models that are suitable for evaluation of agents used to treat infection with hepatitis C virus (HCV) severely hinders the assessment of potential new therapies for the disease. This study created such a model, termed the "HCV-Trimera" model. The HCV-Trimera model was developed by using lethally irradiated mice, reconstituted with(More)
Treatment of chronic hepatitis B virus (HBV) infection with interferon alfa and lamivudine is characterized by lack of viral clearance, loss of response, or emergence of drug-resistant mutants. Thus, new and multiple drug approaches are needed. We have developed two fully human monoclonal antibodies, directed against different epitopes of hepatitis B(More)
BACKGROUND DNA repair is a cellular defence mechanism responding to DNA damage caused in large part by oxidative stress. There is a controversy with regard to the effect of red blood cells on DNA damage and cellular response. AIM To investigate the effect of red blood cells on H2O2-induced DNA damage and repair in human peripheral blood mononuclear cells.(More)
A Trimera mouse is constructed through a three-step process. Firstly, a normal mouse host is rendered immuno-incompetent by a lethal split-dose total body irradiation. Secondly, the myeloid and erythroid lineages are reconstituted by transplantation of bone marrow cells from a genetically immune-deficient mouse donor. Thirdly. the resulting preconditioned(More)
The 2 histone deacetylase inhibitors (HDACIs) approved for the treatment of cutaneous T-cell lymphoma (CTCL) including mycosis fungoides/sezary syndrome (MF/SS), suberoylanilide hydroxamic acid (SAHA) and romidepsin, are associated with low rates of overall response and high rates of adverse effects. Data regarding combination treatments with HDACIs is(More)
BRCA1 mutation is associated with carcinogenesis, especially of breast tissue. Telomere maintenance is crucial for malignant transformation. Being a part of the DNA repair machinery, BRCA1 may be implicated in telomere biology. We explored the role of BRCA1 in telomere maintenance in lymphocytes of BRCA1/2 mutation carriers and in in vitro system by(More)
Transplantation of T-cell-depleted C57BL/6-Nu/ Nu (“nude”) bone marrow (BM) into C3H/HeJ recipients, conditioned with 8 Gy total body irradiation plus chemotherapy with the myeloablative drug dimethyl myleran, resulted in poor hematopoietic reconstitution 14 days posttransplant, compared with transplantation with T-cell-depleted BM from normal C57BL/6(More)
Tyrosine kinase inhibitors (TKIs) have revolutionized the prognosis of chronic myeloid leukemia. With the advent of highly efficacious therapy, the focus has shifted toward managing TKI adverse effects, such as vascular adverse events (VAEs). We used an in vitro angiogenesis model to investigate the TKI-associated VAEs. Our data show that imatinib,(More)
BACKGROUND MicroRNA (miR)-155 contributes to the proliferation of mycosis fungoides (MF) in vitro and is upregulated in tumours of MF compared with early MF lesions. OBJECTIVES To investigate the contribution of miR-155 to the cancerous phenotype and drug resistance of MF/Sézary cell lines. METHODS miR-155 was inhibited in MF cell lines (MyLa and MJ) by(More)
Anemia is a major cause of morbidity and mortality worldwide resulting from a wide variety of pathological conditions. In severe cases it is treated by blood transfusions or injection of erythroid stimulating agents, e.g., erythropoietin (Epo), which can be associated with serious adverse effects. Therefore, there is a need to develop new treatment(More)
