The susceptibility to Fas-mediated apoptosis was evaluated in seven T-cell lines (two infected with HTLV-2, one with HTLV-1, and four HTLV-free) as well as in Jurkat cells transfected with a Tax-2 expressing vector. Fas-mediated apoptosis was significantly reduced in the HTLV-1- and HTLV-2-infected lines in comparison with the HTLV-free lines regardless of the surface expression of Fas antigen ...

early in the development of many animals, before transcription begins, any change in the pattern of protein synthesis is attributed to a change in the translational activity or stability of mrna in the egg and early embryo. as a result, translational control is critical for a variety of developmental decisions, including oocyte maturation and initiation of preimplantation development. in this s...

laffer curve indicates relationship between tax rate and tax income. the aim of this paper is estimating of laffer curve in iranian economy. to do so, we have used threshold regression method. empirical results indicate that since the tax rate is low (the threshold value is less than 0.0848) in two-regime model, tax rate and tax income have a significant positive relationship, but when the tax ...

objective(s):htlv-1 is the first human retrovirus that has been recognized and is associated with ham/tsp and atll. studies have shown that less than five percent of htlv-1 infected carriers develop ham/tsp or atll and about ninety-five percent remain asymptomatic. therefore, the proviral load with tax may affect cellular genes such as cytokines and oncogenes, as well as involve in pathogenicit...

The lack of bovine leukemia virus (BLV) expression is a consistent finding in freshly isolated ovine tumor cells and in the B-cell lines derived from these tumors. In order to gain further insight into the mechanisms of BLV silencing in these tumors, we have used the YR2 B-cell line, which was derived from the leukemic cells of a BLV-infected sheep. This cell line contains a single, monoclonall...

c-Met is a tyrosine kinase receptor for hepatocyte growth factor and suggested to be involved in oncogenesis ormetastatic phenotypes in many malignancies. Adult T-cell leukemia (ATL) is a neoplasia characterized by massive invasion of the leukemic cells into various organs. Recently, we have reported frequent hepatic involvement and the relationship between liver invasion and the poor prognosis...

We examined the effect of the human T lymphotropic virus type 1 (HTLV-I) Tax gene product on the human transforming growth factor beta 1 (TGF-beta 1) promoter. Transfection of deleted constructs of the TGF-beta 1 promoter revealed regions homologous with AP-1 binding sites that were required for Tax-induced transactivation of the TGF-beta 1 promoter. In addition, we examined the expression and ...

malaysia, as a small and developing country, must reduce carbon emissions because the country is one of the top co2-emitting countries in the asean region. therefore, the current study implements two environmental tax policies; carbon and energy taxes, in order to examine the impacts of these policies on the reduction of carbon emission in the whole of the economy by applying a computable gener...

To gain insight into the cellular regulation of bovine leukemia virus (BLV) trans activation, a lambda-gt11 cDNA library was constructed with mRNA isolated from a BLV-induced tumor and the recombinant proteins were screened with an oligonucleotide corresponding to the tax activation-responsive element (TAR). Two clones (called TAR-binding protein) were isolated from 750,000 lambda-gt11 plaques....

UNLABELLED Human T-cell leukemia virus type 1 (HTLV-1)-associated diseases are poorly treatable, and HTLV-1 vaccines are not available. High proviral load is one major risk factor for disease development. HTLV-1 encodes Tax oncoprotein, which activates transcription from viral long terminal repeats (LTR) and various types of cellular promoters. Counteracting Tax function might have prophylactic...
